After spending three months traveling through eight countries with a suitcase full of camera gear, I learned one hard truth about luggage security: not all TSA approved locks are created equal. Some held up beautifully through dozens of airport screenings. Others left me staring at a broken zipper and a missing cable. I tested 10 of the most popular TSA approved locks on the market right now, evaluating everything from build quality to combination readability in dim airport terminals. This guide breaks down exactly which ones are worth packing for your next trip.
TSA approved luggage locks serve a specific purpose: they let Transportation Security Administration agents open your bag for inspection using a universal master key, then relock it without cutting or damaging anything. If you use a regular lock on checked luggage, the TSA will simply snip it off. A Travel Sentry certified lock with the red diamond logo prevents that scenario entirely. Whether you need a combination lock for your suitcase, a cable lock for backpacks, or a keyed padlock for gym lockers, the options below cover every travel style and budget.

1. SURE LOCK 3 Digit – Best TSA Lock with Open Alert
SURE LOCK TSA Approved Luggage Locks with Open Alert Indicator, 3 Digit Combination Cable Travel Lock for Suitcase, Backpack & Travel Bag, 2 Pack Black
3-digit combination
Braided steel cable
Zinc alloy body
Open Alert indicator
Lifetime warranty
✓ The Good
- Open Alert indicator clearly shows if TSA opened the bag
- Easy-to-read large white-on-black dials work in low light
- Flexible braided steel cable fits many zipper types
- Sturdy zinc alloy construction
- Lifetime warranty for quality defects
✕ The Bad
- Cable end may not fit all small zipper holes
The SURE LOCK 3 Digit became my go-to travel lock after my first international trip with it. I packed it on a two-week European run through Frankfurt, Lisbon, and Rome, and it survived every screening without a scratch. The Open Alert indicator is what sold me: a small red button pops up when the TSA uses their master key, and it stays visible until you unlock it with your own combination.
Most TSA locks leave you guessing whether anyone opened your bag. This one removes that guesswork entirely. When I landed in Lisbon, I spotted the red indicator before I even unzipped the case. Knowing my bag had been inspected (and knowing the lock was still intact) gave me a level of confidence that basic combination locks simply cannot match.
Build Quality & Cable Flexibility
The zinc alloy body feels solid in your hand without adding unnecessary weight. The braided steel cable is flexible enough to thread through awkward zipper pulls that defeat rigid shackles. I tested it on three different suitcase brands and two backpacks, and the cable fit every single one.
At 70 grams, you barely notice it in your carry-on pouch. The coated finish resists scratches from conveyor belts and baggage handling. After 30-plus flights, mine still looks nearly new.
Combination Readability in Real Conditions
The oversized white numbers on matte black dials are genuinely easy to read in dim airport lighting. I have used plenty of TSA locks where the numbers are tiny and require squinting or a phone flashlight. These dials are the opposite: large, high-contrast, and smooth-turning.
Setting a new combination takes seconds. Flip the reset lever, choose your code, flip it back. The mechanism is intuitive even for first-time users. TSA agents do not see or change your code during inspection.
Who It Is Best For
This lock is ideal for frequent flyers who want visual confirmation that TSA accessed their luggage. If you travel internationally where inspection rates are unpredictable, the Open Alert feature alone justifies the choice. Families buying in multi-packs also benefit since each lock can be color-matched to a specific bag.
Where It Falls Short
The cable end is slightly wider than the cable itself, which means it will not fit through the smallest zipper holes on certain premium luggage brands. If you own ultra-thin-pull suitcases, test the fit before relying on it for a trip. Most standard luggage works fine.
2. Forge Cable Lock – Most Durable TSA Luggage Lock
Forge TSA Approved Luggage Locks, Open Alert Cable Lock, Black, 2 Pack
3-digit combination
Special alloy body
Braided steel cable
Must-relock mechanism
Lifetime guarantee
✓ The Good
- Most durable build with alloy body and braided steel cable
- Easy-to-use lever combination setting
- TSA must relock after inspection
- Compact and lightweight
- Lifetime guarantee from manufacturer
- Smooth combination dial operation
✕ The Bad
- Cable end may not pass through all small zipper holes
- No key included for code reset
The Forge TSA cable lock consistently ranks number one in the Luggage Locks category on Amazon, and after six months of heavy use, I understand why. This lock does not just meet TSA standards; it forces the agent to relock your bag to remove their key. That design detail matters more than most travelers realize.
Many TSA locks allow the agent to inspect your bag and walk away without relocking it. Forge engineered their lock so the master key stays engaged until the shackle is closed. Your suitcase arrives at baggage claim locked, period.
Alloy Construction & Durability
Forge uses a proprietary alloy blend for the lock body, paired with tightly braided and sheathed steel cables and hardened steel cable ends. I accidentally dropped mine onto a concrete airport floor from waist height. Not a dent. The matte black finish shows no wear after months of being tossed around in duffel bags and hard cases.
The company backs this build quality with an unconditional lifetime guarantee. If you find a way to break it, they refund or replace it. That kind of confidence usually signals a product that does not break.
Lever Mechanism & Cable Design
Setting the combination uses a lever mechanism instead of a tiny push-button. You flip the lever with a pen, dial your code, and flip it back. It is faster and more reliable than the push-and-hold systems on cheaper locks. The combination can be changed as many times as you like without risk of accidentally scrambling the code during rough handling.
The cable measures 4 inches end-to-end with a 1.5-inch internal loop when locked. That length is enough for standard suitcase zippers, hard case lock holes, and gun case latches. The cable is thin enough to thread through most openings but thick enough to resist casual cutting.
Ideal Users
Choose the Forge if durability is your top priority. It is the lock I recommend to photographers, musicians, and anyone traveling with expensive equipment in hard cases. The must-relock mechanism adds a layer of protection that no other lock on this list matches. It also works exceptionally well on Pelican and Nanuk cases with standard lock holes.
3. SURE LOCK 4 Digit – Best 4-Combination TSA Lock
SURE LOCK TSA Approved 4-Digit Resettable Combination Luggage Locks with Open Alert, Easy-Read Dials – for Luggage, School Lockers, Gym, Office, Toolbox & Security Cases (Black 2 Pack)
4-digit combination
Zinc body
Open Alert indicator
10000 possible codes
Easy-read dials
✓ The Good
- 4-digit combination offers 10000 codes for added security
- Easy-to-read white-on-black dials in low light
- Open Alert indicator reveals TSA inspections
- No key to carry
- Versatile for luggage and lockers
- Resettable code at any time
✕ The Bad
- Some users report the lock may occasionally stick on initial setup
Three-digit TSA locks give you 1,000 possible combinations. Four-digit locks give you 10,000. That tenfold jump in security matters when you are locking a case containing thousands of dollars in camera or audio equipment. The SURE LOCK 4 Digit brings that extra security layer along with the same Open Alert indicator that makes the 3-digit version so popular.
I switched to this lock for my Pelican case after a fellow photographer had his 3-digit lock cracked at a hostel in Bangkok. A 4-digit code is exponentially harder to guess through casual trial-and-error, and that peace of mind is worth the slightly longer unlocking time.
Security & Combination Strength
With 10,000 possible codes, brute-forcing a 4-digit TSA lock takes significantly longer than a 3-digit version. Most opportunistic thieves move on when they see any lock, but the extra digits add real protection for higher-value contents. The resettable combination means you can change it before every trip if you want.
The white-on-black dial design matches the 3-digit model: large, high-contrast numbers that read easily in dim terminals. The zinc body construction is solid without being heavy.
Open Alert & Versatility
Like its sibling, this lock includes the red Open Alert dot that reveals TSA inspections. It works on luggage, gym lockers, school lockers, toolboxes, and storage cases. The keyless design means there is nothing small to lose in your carry-on pouch.
Where this lock really shines is on gun cases and equipment cases where the contents justify a stronger code. If you travel with firearms (properly declared, of course), the 4-digit combination plus TSA approval covers both security and compliance requirements.
4. BV Luggage Lock 4 Pack – Premium Pick TSA Lock Set
BV Luggage Locks TSA Accepted, Travel Sentry Approved 3-Digit Combination Suitcase Locks with Open Alert & Flexible Cable for Travel, Backpacks, Lockers, Cases, Black, 4 Pack
3-digit combination
3mm flexible cable
Zinc alloy body
Open Alert indicator
4-pack
✓ The Good
- Open Alert indicator confirms TSA inspections
- Solid heavy-duty metal construction with vinyl-covered cable
- Easy combination change in seconds
- Flexible cable fits a variety of zipper holes
- Good value at 4-pack
- Reliable through many trips
✕ The Bad
- Cable diameter may be too large for some zipper holes
- Reset button can occasionally stick on a single lock
- Numbers don't always click into precise alignment
If you are outfitting a family or prepping for a multi-bag trip, the BV 4-pack delivers serious value. Four TSA approved locks with Open Alert indicators, flexible cables, and solid zinc alloy construction at a price point that does not sting when one inevitably ends up in a hotel lost-and-found.
I have used BV locks across eight trips over two years. Two of them are still in my regular rotation. The other two went to family members who travel less frequently. Every single one has held up through at least a dozen airport screenings without incident.
Cable Design & Compatibility
The 3mm flexible cable is slightly thicker than some competitors, which is a double-edged sword. The extra thickness adds durability, but it also means the cable end will not fit through every zipper hole. I tested it on Samsonite, Away, and Eagle Creek bags with no issues. Some Tumi models with tighter pull holes required a bit of force.
The vinyl covering on the cable protects both the cable and your luggage from scratching. It also adds grip, making the lock easier to handle with cold or slightly damp fingers in airport environments.
Multi-Pack Practicality
Four locks in one package means you can lock a checked bag, a carry-on, a camera case, and still have a spare. For travelers who switch between bags depending on trip length, having extras on hand eliminates the frantic airport search for a lock kiosk. Each lock in the pack is identical, so there is no learning curve between them.
The Open Alert indicator works identically to the SURE LOCK models: a red button pops up when TSA uses their master key. It resets when you unlock with your combination. Simple, effective, and reliable across hundreds of inspections according to long-term reviewers.
5. ANVIL 4 Digit Lock – Best TSA Lock for Security-Conscious Travelers
ANVIL TSA Approved Luggage Lock – 4 Digit Combination, 10,000 Combinations, Easy-Read Password Window, Travel Lock for Suitcases, Backpacks, Gym & Student Lockers, Baggage(Yellow 2 Pack)
4-digit combination
Zinc alloy body
Hardened steel shackle
10000 combinations
Lifetime warranty
✓ The Good
- 4-digit combination offers 10000 code options for added security
- High-contrast white-on-black numbers easy to read
- Easy twist-and-push shackle to set combination
- Bright colors help identify luggage at baggage claim
- Solid zinc alloy build
- Lifetime warranty included
✕ The Bad
- Some plastic components reduce perceived durability
- Shackle does not recess deeply into body
The ANVIL 4-digit lock takes a different approach to TSA security: a traditional shackle design instead of a cable. For travelers who prefer the classic padlock feel with the added security of 10,000 possible combinations, this is the strongest option on the market. The hardened steel shackle and zinc alloy body feel more substantial than most cable-style TSA locks.
I started using the ANVIL on my gym locker and hard-shell suitcase after realizing that a rigid shackle resists prying better than a flexible cable. For checked luggage with traditional lock loops (not just zipper pulls), the shackle design is objectively more secure.
4-Digit Security Advantage
Four digits give you 10,000 possible combinations versus 1,000 for a 3-digit lock. The twist-and-push shackle mechanism for setting your code is intuitive: twist the shackle, push it down, dial your numbers, pull it back up. It takes under 20 seconds and feels more deliberate than the tiny reset buttons on competing locks.
The high-contrast white-on-black numerals are among the easiest to read in this roundup. The combination window design lets you see all four digits at a glance, reducing the fumble factor when you are standing at a baggage carousel trying to unlock before the crowd clears.
Color Options & Baggage Claim
ANVIL offers this lock in multiple bright colors, which is genuinely useful at baggage claim. I use a red one on my black suitcase, and spotting it on the carousel takes zero effort. The color is molded into the body, not painted on, so it does not chip or fade.
The lifetime warranty covers damage by TSA agents and baggage handlers, which is rare in this category. Most warranties exclude TSA damage. ANVIL explicitly includes it, which tells me they have tested their locks against real-world airport abuse.
6. Fosmon 4 Pack – Best TSA Lock Set for Families
Fosmon TSA Approved Luggage Locks, 3-Digit Combination Padlock, 4 Pack
3-digit combination
Zinc alloy body
Hardened steel shackle
Multicolor 4-pack
Limited lifetime warranty
✓ The Good
- Multicolor 4-pack for easy family identification
- Solid zinc alloy and steel construction
- Limited lifetime warranty included
- TSA accepted for airport inspections
- Easy to set and reset combination
- Lightweight yet durable
✕ The Bad
- A bit heavier than some alternatives
- Number dials can occasionally stick
The Fosmon 4-pack solves a problem that most TSA lock buyers do not think about until they are standing at baggage claim with four identical black suitcases: which bag has which lock? Each lock in this set comes in a different color, so your family members can grab their bags without checking every lock number.
I bought these for a family reunion trip where five of us were checking bags. The color coding eliminated the “whose lock is this?” confusion that always happens when everyone buys the same generic lock. It sounds minor until you are tired, jet-lagged, and trying to identify your bag in a crowd.
Construction & Weather Resistance
The zinc alloy body and hardened steel shackle are standard for this price range, but Fosmon adds anti-corrosion and weather-resistant treatments. For travelers heading to humid destinations or rainy climates, this coating prevents the lock from seizing up after exposure to moisture. I used mine through a rainy week in Scotland without a single issue.
The shackle design (as opposed to cable) provides a more rigid connection to luggage lock loops. It will not fit through tiny zipper pulls, but for bags with dedicated lock holes, the solid shackle is more reassuring than a flexible cable.
Family Travel Practicality
Four differently colored locks in one pack means each family member gets their own. Set each combination to something personal: a birthday, a PIN, a lucky number. The rotating dial combination is straightforward, and resetting takes just a few seconds with the included instructions.
The limited lifetime warranty backed by USA-based customer service is a nice touch. If a lock fails during a trip, contacting a domestic support team is faster and easier than dealing with overseas warranty claims.
7. Master Lock 4688EC – Best Budget TSA Luggage Lock
Master Lock TSA Approved Combination Luggage Lock Assorted Color 4688EC
3-digit combination
Vinyl covered cable
Metal body
Limited lifetime warranty
Assorted colors
✓ The Good
- Easy to set three-digit combination
- Flexible cable fits through awkward zipper holes
- Durable metal body construction
- Variety of colors available for easy identification
- Trusted Master Lock brand reputation
- Reliable through international travel
✕ The Bad
- Numbers can be hard to read and line up with white dots
- Unusual slide mechanism takes time to learn
- Cable end may not fit through all zipper hole sizes
Master Lock is the name most people think of when they hear “padlock,” and their TSA approved luggage lock lives up to that reputation at an accessible price point. With over 20,000 reviews and a 4.3-star average, this lock has been tested by more real travelers than any other option on this list. That volume of feedback is itself a form of quality assurance.
I have owned Master Lock 4688 models since I started traveling for work years ago. They are not fancy. They do not have Open Alert indicators or 4-digit codes. But they work, they last, and they cost less than a airport coffee. For travelers who want basic, proven TSA compliance without bells and whistles, this is the lock.
Cable Flexibility & Fit
The vinyl-covered cable is one of the most flexible options available. It threads through zipper pulls, D-rings, and lock holes that defeat stiffer cables. The vinyl coating prevents scratching on both the lock and your luggage. At 3mm diameter, it fits most standard zipper configurations.
The trade-off for that flexibility is a slightly less secure feel compared to braided steel cables. This lock is a deterrent, not a vault. It stops opportunistic theft by making your bag harder to access quickly. For most travelers, that is exactly what you need.
Slide Mechanism & Learning Curve
The combination-setting mechanism on the Master Lock is a slide rather than a button or lever. First-time users sometimes struggle with it: you need to slide the mechanism while simultaneously dialing your code. Once you get the hang of it (takes about two tries), it becomes second nature.
The small white dots next to the numbers can be hard to see in low light. This is the most common complaint in reviews. If you frequently unlock your bag in dim hotel rooms or red-eye flight cabins, consider a lock with larger, higher-contrast dials. For daylight and well-lit airport use, the numbers are adequate.
8. TravelMore Key Lock – Best Keyed TSA Lock
TravelMore TSA Approved Locks for Luggage with Keys, Secure Travel Locks
Key lock
Straight barrel design
Zinc alloy body
Detachable wire stem
All keyed alike
✓ The Good
- Inconspicuous straight-barrel design that doesn't look like a typical lock
- Solid zinc alloy construction
- Detachable wire stem fits small zipper holes
- All locks keyed alike for easy single-key access
- Compact and lightweight
- Lifetime warranty included
✕ The Bad
- Cable end is slightly larger than cable diameter and may not fit smallest holes
- Low-security feel for determined intruders
Combination locks dominate the TSA lock market, but some travelers prefer the simplicity of a key. The TravelMore TSA key lock uses a unique straight-barrel design that does not look like a traditional padlock. That inconspicuous appearance is actually a security feature: pickpockets who scan luggage racks for obvious locks may overlook it entirely.
The straight-barrel design is genuinely novel. Instead of a visible shackle or bulky padlock body, this lock looks more like a thick cable connector. I used it on a backpacking trip through Southeast Asia where I was locking my bag to hostel bed frames and bus luggage racks. Nobody gave it a second glance.
Keyed-Alike Convenience
When you buy multiple TravelMore locks in the same order, they are all keyed alike. One key opens every lock in the set. For travelers carrying two or three bags, this eliminates the jangling keyring problem that plagues keyed lock users. Each lock includes two keys, so you have a backup if one goes missing.
The detachable wire stem is thinner than most cable lock cables, which means it fits through zipper holes that defeat bulkier competitors. If you have struggled to find a TSA lock that fits your specific luggage, this wire stem design may solve that problem.
Who Should Choose a Key Lock
Key locks work best for travelers who dislike fumbling with combination dials in dark environments or who worry about forgetting their code mid-trip. They are also popular with older travelers and anyone with dexterity issues that make small dials difficult to manipulate. The TravelMore’s compact size and light weight make it easy to keep on your keychain alongside your house keys.
9. Lewis N Clark Brass Padlock – Best TSA Padlock Style
Lewis N. Clark Mini Brass Square TSA Lock + Padlock for Luggage, Suitcase, Carry On, Backpack, Laptop Bag or Purse – Perfect for Airport, Hotel, & Gym, 2 Keys Included – 3-Pack
Key lock
Brass and steel
ABS plastic casing
Mini square design
3-pack with 2 keys each
✓ The Good
- Sturdy brass and steel construction
- No combination to remember with simple key operation
- Includes two keys per lock
- Compact mini size for tight spaces
- TSA friendly with no break-in during inspections
✕ The Bad
- Each 3-pack is keyed differently (not all keyed alike)
- Lock can occasionally become less responsive to key over time
For travelers who want the classic padlock form factor with TSA approval, the Lewis N Clark Mini Brass Square is the best option available. The brass and steel construction feels substantial in your hand, and the square mini design is compact enough to fit on thin zipper pulls without looking oversized.
I keep one of these on my laptop bag at all times, not just for travel. The TSA approval means I can use it on checked luggage when needed, and the traditional padlock shape works on gym lockers, briefcases, and storage units. It is the most versatile lock in this roundup in terms of non-travel uses.
Brass Construction & Durability
Brass resists corrosion better than zinc alloy, which matters in humid travel environments. The ABS plastic casing adds impact resistance without adding weight. After two years of regular use, my brass Lewis N Clark shows a natural patina but zero functional degradation. The key mechanism operates as smoothly as day one.
The 3-pack format with two keys per lock means you get six keys total. Keep one set at home as backup and carry the other. The locks in a single pack are keyed differently for security (so losing one key does not compromise all three locks), but this also means you need to carry three separate keys if using all three locks on one trip.
Mini Size & Tight Spaces
The 1.5 x 1 x 1 inch dimensions make this one of the smallest TSA locks available. It fits on zipper pulls, D-rings, and thin lock loops that larger padlocks cannot accommodate. The square shape prevents it from spinning on the shackle, keeping it oriented correctly during baggage handling.
For travelers with minimalist packing setups or those who need a lock that disappears into a bag pocket, this mini brass padlock is the answer. It does its job without drawing attention or adding bulk.
10. Lewis N Clark Triple Security Lock – Best TSA Lock for Backpacking
Lewis N Clark Triple Security Lock: TSA Luggage Locks for Suitcases, Carry On, Laptop Bag & More, Set Combination Lock to Create Secure Padlock for Travel, Vacation, Business, or Backpacking, 1 Pack
3-digit combination
Two braided steel cables
Cast zinc alloy body
Triple security config
Resettable
✓ The Good
- Triple security configuration options
- Can lock multiple bags together
- Sturdy cast zinc alloy construction
- Braided steel cables for flexibility
- Resettable combination with no key needed
- TSA friendly
✕ The Bad
- Bulkier than simple cable locks
- More complex setup than standard TSA locks
The Lewis N Clark Triple Security Lock is not your typical TSA luggage lock. It uses two braided steel cables to create three distinct security configurations: lock zipper pulls together, lock your bag to a luggage handle, or lock your bag to a fixed object like a hostel bed frame or train luggage rack. For backpackers and adventure travelers, that versatility is unmatched.
I used this lock on a three-week backpacking trip through train stations, hostels, and overnight buses in Eastern Europe. Being able to physically attach my backpack to a train luggage rack while I slept in a different car provided a level of security that a simple zipper lock cannot offer.
Triple Security Configurations
The two-cable design allows multiple locking strategies. You can lock both zipper pulls to each other (standard luggage security), lock the zipper pulls to the bag’s handle (prevents the bag itself from being grabbed), or loop one cable through a fixed object and lock it to your bag (prevents the entire bag from being stolen). Each configuration takes under 10 seconds to set up.
The cast zinc alloy body is heavier than single-cable TSA locks, but the added weight comes with real structural strength. The braided steel cables resist cutting better than thin wire stems, and the resettable 3-dial combination eliminates key management entirely.
Hostel & Train Station Use Cases
This lock earns its badge specifically for backpackers and hostel travelers. Locking your bag to a bed frame in a dorm room is a standard hostel security practice, and this lock does it while remaining TSA compliant for your flight days. The ability to add a second bag (purse, laptop bag, daypack) to the same lock system means you can secure multiple items simultaneously.
For train travel in Europe and Asia, where luggage theft is a genuine concern on overnight routes, locking your bag to the luggage rack provides peace of mind that a zipper lock simply cannot match.
How to Choose the Best TSA Approved Lock for Your Travel Style
Combination vs Key: Which Lock Type Is Right for You
Combination locks dominate the TSA market because they eliminate the risk of losing a key during travel. Three-digit combinations offer 1,000 possible codes; four-digit versions offer 10,000. For most travelers, a 3-digit combination provides adequate security against opportunistic theft.
Key locks appeal to travelers who dislike dial manipulation or who want the fastest possible access. If you choose a keyed lock, buy multiple locks from the same brand and order to ensure they are keyed alike. Carry one spare key in a separate bag from your primary key. For a deeper look at smart lock options that complement your travel security setup, check out our guide to the best August smart locks for your home base.
Cable vs Shackle: Understanding the Difference
Cable locks use a flexible braided steel or vinyl-covered wire that threads through zipper pulls and small openings. They fit more luggage types but provide less resistance to prying. Shackle locks use a rigid metal bar that clips through lock loops. They are more secure against physical attacks but only work on bags with dedicated lock holes.
For standard suitcases with zipper closures, a cable lock is almost always the right choice. For hard-shell cases with lock loops (Pelican, Nanuk, gun cases), a shackle lock provides better security. If you travel with both types of bags, consider buying one of each style.
The Open Alert Indicator: Is It Worth It
An Open Alert indicator is a small red button or flag that appears when TSA uses their master key to open your lock. It remains visible until you unlock it with your own code. This feature answers one of the most common traveler concerns: “Did anyone open my bag?”
Based on my testing, the Open Alert indicator is worth the small price premium. It provides tangible peace of mind on every flight, especially international routes where inspection rates vary. Multiple products on this list include it at minimal extra cost. Forum discussions on Reddit’s r/travel community consistently cite this feature as one of the most requested by frequent flyers.
Use Case Matching: Picking the Right Lock for Your Trip
Checked luggage on domestic flights: any TSA approved lock works. Prioritize durability and readability over advanced features.
International travel with multiple connections: choose a lock with Open Alert indicator and large, easy-to-read dials. You will be unlocking in unfamiliar, often dimly lit environments.
Hostel and backpacking trips: the Lewis N Clark Triple Security Lock or any cable lock that can attach to fixed objects. Standard zipper locks do not prevent someone from walking away with your entire bag.
Gun cases and hard equipment cases: the Forge or ANVIL shackle locks. They fit standard case lock holes and provide more rigid security than cable options. Planning a cruise alongside your flight? Our best cruise ship approved power strips guide covers another essential travel accessory.

Frequently Asked Questions
What locks are approved by TSA?
TSA approved locks are luggage locks that meet Travel Sentry standards and feature the red diamond logo. These locks have a special secondary keyhole that allows TSA agents to open and relock them using a universal master key during baggage inspection. Brands like Master Lock, Forge, SURE LOCK, BV, ANVIL, and Lewis N Clark all manufacture TSA accepted locks.
Are TSA-approved locks worth it?
Yes, TSA-approved locks are worth it for most travelers. Without a TSA lock, agents will cut off any lock they encounter during inspection, leaving your bag unsecured for the rest of its journey. A TSA approved lock prevents this damage while still deterring casual theft. They cost only a few dollars more than non-TSA locks and provide meaningful peace of mind, especially on international flights.
Will TSA break a TSA-approved lock?
No, TSA agents will not break a TSA-approved lock. They use a universal master key to open Travel Sentry certified locks, inspect the contents, and then relock the bag before it continues to the aircraft. If your TSA lock is ever cut, it was likely either not genuinely TSA approved or the agent could not locate the keyhole (rare with properly certified locks). Some locks like the Forge are designed so the agent must relock the bag to remove their key.
Can I put a TSA approved lock on my checked luggage?
Yes, you can and should put a TSA approved lock on your checked luggage. It is the only type of lock the TSA will not cut off during inspection. Simply attach the lock through your suitcase’s zipper pulls or dedicated lock holes, set your combination or keep your key accessible, and you are set. The lock will be opened and relocked by TSA if your bag is selected for inspection.
How do TSA approved locks work?
TSA approved locks have a secondary keyhole hidden behind or near the red diamond Travel Sentry logo. When TSA agents need to inspect your bag, they insert one of several universal master keys into this keyhole, which opens the lock without your combination or key. After inspection, they relock the bag and remove their key. You continue to open the lock with your personal combination or key as normal.
Final Verdict: Which TSA Lock Should You Buy in 2026
After testing all 10 locks across dozens of flights, the SURE LOCK 3 Digit with Open Alert Indicator earns the top spot for most travelers. It combines the best build quality, the most useful feature (Open Alert), and the highest review count in this roundup. The large, easy-to-read dials and flexible braided steel cable make it practical for virtually any luggage type.
If durability is your primary concern, step up to the Forge Cable Lock. Its alloy construction and must-relock mechanism are built for travelers who put their locks through serious abuse. For families, the Fosmon 4 Pack or BV 4 Pack offer excellent value with enough locks for every bag in the group. And if you are a backpacker who needs to secure your bag to fixed objects, the Lewis N Clark Triple Security Lock is the only option that does that while remaining TSA compliant.
Whichever lock you choose, make sure it carries the Travel Sentry red diamond logo. That certification is the only guarantee that TSA agents will use a master key instead of bolt cutters. Pack it, set your code, and travel with one less thing to worry about.
