The fastest places to buy TSA-approved locks
TSA-approved locks are sold at most major retailers that carry luggage and travel gear. Amazon, Target, Walmart, and Best Buy stock them online and in stores. Travel specialty shops like The Container Store and REI carry multiple brands. Airport shops sell them, though at a markup. If you need one when ready before a flight, an airport Hudson News or similar newsstand usually has basic models in stock.
The lock must have the red diamond logo or the words "TSA-approved" printed on the packaging. Without that marking, Transportation Security Administration officers can cut it open during screening, and you will not know until you land. Buy from a seller that clearly shows the logo in product photos — this saves a return trip if the lock arrives without TSA certification.
Key Takeaways
- Amazon, Walmart, Target, and Best Buy carry TSA-approved locks online and in physical stores, with prices ranging from $8 to $25 for a single lock.
- The red diamond TSA logo must appear on the lock itself or packaging; locks without it can be cut open by security without compensation.
- Travel specialty retailers like REI and The Container Store stock multiple brands and can explain the difference between combination and key locks.
- Airport shops have locks available but charge 50 to 100 percent more than retail prices, so buying before travel saves money.
- Luggage sets often include a TSA lock, so check what comes with your bag before buying separately.
Online retailers with the widest selection
Amazon carries the most TSA-approved lock options — combination locks, key locks, cable locks, and padlocks from brands like Master Lock, Delsey, and Samsonite. Filter by "TSA-approved" in the search results to avoid non-certified locks. Prices start around $8 for a basic combination lock and go up to $20 for heavier-duty models. Read the reviews to see whether the combination dial is stiff or loose, because that affects how long the lock lasts.
Walmart and Target stock TSA locks both online and in their travel sections. Walmart's website shows in-store availability by zip code, so you can pick one up the same day if you are near a location. Target carries fewer brands than Amazon but prices are similar. Both sites clearly mark which locks have the TSA logo, so there is no guessing at checkout.
Specialty travel retailers
REI and The Container Store focus on travel gear and stock TSA-approved locks alongside luggage. REI members get a discount on most locks, and staff can explain the trade-offs between combination and key models — combination locks are easier to remember but slower to open, while key locks are faster but you have to carry the key. The Container Store's website shows which models fit specific luggage brands, which is useful if your bag has a built-in lock slot.
Local luggage repair shops often carry TSA locks and can test whether a lock works with your specific bag before you buy. This matters if your luggage has an unusual lock slot or if you want to match the existing hardware. Call ahead to confirm they have TSA-approved models in stock.
What to check before buying
Verify the lock has the red diamond TSA logo printed on it or on the packaging. The logo is small but unmistakable — it looks like a red diamond with "TSA" inside. If a product listing does not show the logo in photos, ask the seller in the comments or contact customer service. A lock without this marking will be cut open at security, and TSA does not reimburse for damage.
Check whether your luggage already has a built-in TSA lock. Many modern suitcases from brands like Samsonite, Delsey, and Away include one. If it does, you do not need to buy a separate lock. If your bag has a lock slot but no lock, measure the slot width — most are 7 to 10 millimeters — so you buy a lock that fits.
Decide between a combination lock and a key lock. Combination locks are more convenient because you do not carry a key, but the dial can wear out after heavy use. Key locks are more durable but you have to keep the key with you. For frequent travelers, a key lock lasts longer. For occasional trips, a combination lock is simpler.
Price comparison across retailers

| Amazon | $8–$25 | 20+ brands and styles | Ships in 1–2 days with Prime |
| Walmart | $10–$20 | 5–8 models | In-store same-day pickup available |
| Target | $10–$18 | 4–6 models | In-store same-day pickup available |

| Airport shops | $20–$35 | 1–3 basic models | when ready availability |
Amazon and Walmart offer the best value for price. Airport shops charge double but are the only option if you forgot a lock and your flight leaves in hours. If you have time before your trip, order online — the savings add up if you travel more than once a year.
What happens if you buy a non-TSA lock
TSA officers will cut open any lock that does not have the red diamond logo. They do this during baggage screening, and you will not be present to see it happen. The lock is destroyed and cannot be reused. TSA does not pay for damaged locks or the contents inside if something goes missing during the cutting process.
A cut lock also means your bag is open for the rest of your journey. If you are connecting through multiple airports, your luggage could be accessed at any point. For this reason, buying the correct lock the first time is worth the few minutes it takes to verify the logo before checkout.
Frequently Asked Questions
Can I use a regular padlock instead of a TSA-approved one?
No. TSA will cut any lock without the red diamond logo. A regular padlock offers no protection and will be destroyed during screening. Only locks marked TSA-approved can be opened by TSA officers with a master key, which means your bag stays locked during transit.
Do I need a TSA lock if I am flying domestically?
You do not need one for domestic flights, but TSA recommends it because baggage handlers can open your bag without your knowledge. A TSA lock lets you lock your bag and still allow TSA to inspect it without cutting the lock. If you fly internationally, you will need one for the return trip through U.S. security.
What is the difference between a TSA combination lock and a TSA key lock?
Combination locks have a dial you spin to enter a code; you do not carry a key. Key locks require a physical key to open. Combination locks are more convenient for travel because you cannot lose the key, but the dial mechanism wears out faster. Key locks last longer but you have to keep the key safe and accessible.
Can I buy a TSA lock at the airport if I forget one?
Yes, but expect to pay $20 to $35 for a basic lock that costs $8 to $12 online. Airport shops have limited selection and charge a premium for convenience. If your flight is more than a few hours away, buying online and picking it up at a nearby store is cheaper.
Will a TSA lock work on all luggage?
Most TSA locks fit standard luggage lock slots, which are 7 to 10 millimeters wide. Some luggage has built-in locks or non-standard slots. Check your bag's manual or measure the slot before buying. If your luggage has a built-in TSA lock, you do not need a separate one.
