You can buy TSA locks at most major retailers, both online and in stores

TSA locks are sold at luggage shops, hardware stores, big-box retailers, and online marketplaces. The most common places are Amazon, Walmart, Target, Home Depot, Lowe's, and specialty luggage retailers like eBags or Samsonite's direct site. Airport shops also carry them, though prices run higher. You do not need to buy from a specific brand — any lock marked "TSA-approved" will work, and the TSA does not sell locks directly.

The lock must display the red diamond logo, which means TSA agents have a master key that opens it without damaging your luggage. Without that mark, security will cut the lock if they need to inspect your bag. Price ranges from $5 to $25 per lock depending on type and brand.

Key Takeaways

  • TSA locks must display the red diamond logo to allow TSA agents to open them without cutting.
  • Online retailers like Amazon and Walmart usually stock the widest selection and lowest prices.
  • Combination locks are cheaper and more convenient than key locks, since you cannot lose the key in transit.
  • Luggage retailers and airport shops carry TSA locks but charge more than general retailers.
  • You need one lock per bag if you want to lock multiple pieces of luggage.

Online retailers have the most stock and lowest prices

Amazon carries dozens of TSA-approved lock models, from basic combination locks to cable locks and padlocks. Prices start around $5 to $8 for a single combination lock. Walmart and Target both stock TSA locks online and offer in-store pickup, which saves shipping time. eBay also has many options, including bulk packs if you travel frequently or need locks for multiple bags.

Online shopping lets you compare brands side by side and read reviews from other travelers. Look for locks with at least 100 reviews and an average rating of 4 stars or higher. Many online retailers offer free shipping on orders over a certain amount, which can offset the cost if you are buying multiple locks.

Hardware and big-box stores stock TSA locks in the luggage or security section

Home Depot and Lowe's carry TSA-approved combination locks and cable locks in their security or hardware sections. Walmart and Target stock them near luggage or in the travel accessories aisle. Prices are similar to online, usually $6 to $15 per lock, and you can inspect the lock in person before buying.

The advantage of buying in-store is that you can leave with the lock the same day, which matters if you are packing for a trip that leaves soon. Staff at these stores can also point you to the TSA-approved section if you cannot find it, though they may not know much about the locks themselves.

Luggage retailers and airport shops charge more but offer convenience

Specialty luggage stores like eBags, Samsonite, and local luggage repair shops carry TSA locks and often bundle them with luggage purchases. Prices run $10 to $20 per lock. These retailers can also advise you on which lock works best with your specific luggage brand.

Airport shops sell TSA locks at a premium — often $15 to $25 — because they know travelers need them at the last minute. If you forgot a lock and your flight is in a few hours, an airport shop is your only option, but plan to pay more. Some airports have Hudson News or similar shops in the terminal; check your airport's website for store locations.

Combination locks are more practical than key locks for travel

Combination locks cost $5 to $12 and do not require carrying a key. You set your own code and can reset it if you forget. The downside is that combination locks are slower to open and close than key locks, and the dial can wear out over time.

Key locks cost $8 to $15 and open faster, but you have to keep track of the key during your trip. If you lose the key, you cannot open the lock without cutting it. Many travelers prefer combination locks for this reason, especially on international trips where losing a key in a foreign airport is a real risk.

Cable locks and luggage straps offer a different approach

Cable locks thread through the zippers of your luggage and lock them together, preventing someone from opening the bag during transit. They cost $6 to $15 and work well for soft-sided luggage. Luggage straps wrap around the entire bag and lock with a combination or key, adding a visual deterrent.

Cable locks are lighter and more flexible than padlocks, which matters if you travel with carry-on only. They do not work on hard-sided luggage with no zipper access. Luggage straps are bulkier but find the entire bag, not just the zippers, and some travelers use both a strap and a padlock for extra security.

What to check before you buy

Look for the red diamond TSA logo on the packaging or product description. If it is not mentioned, the lock is not TSA-approved and TSA will cut it. Check the lock type — combination, key, or cable — and decide which fits your travel style. Read reviews that mention durability, since cheap locks can jam or break after a few trips.

If you buy online, confirm the seller ships to your location and that delivery arrives before your trip. If you are buying at a store, test the lock mechanism to make sure the dial turns smoothly or the key fits without sticking. A lock that is hard to use now will be frustrating at the airport.

Frequently Asked Questions

Do I need a TSA lock or can I use any lock?

You need a TSA-approved lock marked with the red diamond logo. TSA agents have master keys for these locks and can open them without damage. If you use a regular lock, TSA will cut it off if they need to inspect your bag, and you will lose the lock.

Can I buy a TSA lock at the airport?

Yes, most airports have shops that sell TSA locks, usually in the terminal or near baggage claim. Prices are higher than retail stores — expect to pay $15 to $25 — but it is an option if you forgot one before arriving at the airport.

How many locks do I need?

You need one lock per bag if you want to lock multiple pieces of luggage. If you only check one bag, one lock is enough. Some travelers buy two or three at once to have spares for future trips or to lock both a suitcase and a personal item.

Are expensive TSA locks better than cheap ones?

Price does not always mean better quality. A $5 combination lock from a major retailer works just as well as a $20 one, as long as it has the red diamond logo and good reviews. Expensive locks may have features like a cable or strap, but the basic function is the same.

What if I lose my TSA lock key?

If you lose the key to a key-lock, you will need to cut it off. Combination locks avoid this problem since there is no key to lose. If you use key locks regularly, consider keeping a spare key at home or buying combination locks instead.
