The 13 Best Travel Accessories of 2021 Best Cable Lock: LuminTrail TSA Approved Cable Luggage Lock Buy on Amazon With three color options, this TSA-approved lock from Lumintrail prioritizes flexibility. The steel cable attached to the lock is thin enough to slip through the smallest of zippers, and it comes with an extra 4-foot cable that works great for securing luggage together or stabilizing zipper pulls. If you find yourself in need of a TSA-approved lock that will work just as well for your backpack as it does your hard-sided luggage, opt for this flexible cable lock. Best Combination Lock: Forge TSA Luggage Combination Lock Buy on Amazon Buy on Walmart Forge’s combination locks come with special keys that feature a dimpled design, making the locks much harder to pick. If you’ve ever retrieved your luggage and noticed the lock hanging open or stuffed back into your suitcase, rest assured you won’t have to worry about that happening with this lock. It's designed so that the TSA agent has to re-lock the suitcase in order to remove their key. The 11 Best Wallets for Men of 2021 Best Key Lock: Master Lock Padlock Buy on Amazon Buy on Walmart Master Lock’s padlock is designed with front access, which makes locking and unlocking easier on the wrists. The steel shackle gives you all the protection you need against those looking to cut the lock off, and both locks in the set can be opened with the same key (you get two keys in the pack). Another bonus: These locks are available in two colors (purple and blue) making them easier to spot in the mess of packing and unpacking. Best Retractable Cable Lock: Lewis N. Clark Retractable Cable Lock Buy on Amazon Buy on Walmart If you don’t want to mess with any additional accessories like keys or extra cables, this retractable design from Lewis N. Clark may be just what you’re looking for. A 30-inch steel cable provides plenty of flexibility for securing multiple pieces of luggage or looping your zipper pulls together. An easy-to-use, three-number combination allows the user to open and close the lock. Reviewers say that this option is better for carry-on luggage, as steel shackle styles provide more security for when your bag is completely out of your hands and sight. Final Verdict You really can’t go wrong with the durability, strength, and security of the Tarriss TSA Lock with SearchAlert (view at Amazon). Knowing that your luggage is safe is one thing, but it’s nice to know whether or not a TSA agent has rummaged through your things: the SearchAlert technology built in to this lock is a nice touch you don’t see with many other options. What to Look For When Buying a TSA-Approved Lock Price Luggage locks vary quite a bit in price, but you won’t find many over $20. It depends on the level of security you’re looking for: steel shackle locks can run a bit more expensive, as do keyless options that require a card to unlock. Beware of super-inexpensive options—paying a few dollars more on your luggage lock can make all the difference. Durability Most TSA-approved locks are made of steel, which is an ultra durable material. Steer clear of locks made completely of rubber or plastic, as well as locks with cables that are anything but steel. Style There are a few common styles of TSA-approved locks: combination locks, cable locks, and keyless locks. Consider your own personal preferences when making your choice: Do you constantly lose your keys? Stay away from locks that require one to open. Need a bit of flexibility to lock up a bag with small zipper holds? Look for a super-strong cable lock with a thinner cable. Anxious about someone cracking your combination code? Opt for a card-access lock. FAQs How do I know if a lock is TSA-approved? Every TSA-approved lock will have a red diamond logo, also known as a Travel Sentry logo. This means that it’s compatible with the universal keys that TSA agents have to unlock these approved locks. Are cable locks easier to break? Not necessarily. Most cable locks are made with durable, steel cables — this means you’d need a pretty heavy duty wire cutter to break through. If that still has you worried, choose a steel shackled lock instead, just know that they are less flexible in terms of what you can affix it to (larger shackles don’t often work well with smaller zipper pulls). What happens if I don’t use a TSA-approved lock? It’s not illegal to lock your luggage with a non-approved lock, but you are running the risk of a TSA agent cutting your lock off should they need to search your bag(s). There isn’t often a price difference between TSA-approved and non-approved locks, so you’re always better off going with one that the TSA can access. Why Trust TripSavvy?
