Luggage locks

Luggage locks help keep zip pulls together, discourage casual tampering, and make a suitcase harder to open in transit. The best option depends on how you travel. For checked bags, TSA-approved luggage locks are usually the most practical choice, especially when you are packing long-haul travel essentials. For carry-ons, backpacks, and duffle bags, a small combination lock or cable lock is often enough. You can also browse locks and related gear in our travel accessories.

Why travellers use suitcase locks

A travel lock is mainly a deterrent. It will not make a bag impossible to open, but it can slow down opportunistic access and stop zips from working loose during handling. That is useful on checked luggage, lockable backpacks, and soft travel bags. If your suitcase already has a built-in lock, use it. If not, a compact luggage padlock or cable lock gives you an easy extra layer of security. For identification and recovery, make sure your bag is clearly labelled—see how to fill luggage tags.

When a TSA-approved lock makes sense

If your journey includes the US, or you simply want fewer problems during airport checks, choose a TSA lock. TSA-approved locks use a system recognised by airport security so a bag can be opened for inspection and relocked without cutting the lock. Many models are also marked Travel Sentry. If you see codes such as TSA007 on the lock body, that refers to the security access type, not to your personal code. Travellers do not need a TSA key to use these locks. Keep important documents separate and secure as well—our travel document organiser guide explains how.

How to use a luggage lock correctly

On a zip suitcase

Bring the two zip pulls together, pass the shackle or cable through both eyelets, and close the lock fully. If it is a combination lock, scramble the numbers after locking and test that the zip pulls cannot separate. Keep your code somewhere safe and avoid using an obvious number such as 000 or a birth year. For extra case security during handling, a strap can help—see how to use luggage straps.

On luggage with a built-in lock

Many hard-shell suitcases have a built-in TSA combination lock. If you are still comparing hard shell vs soft luggage guide, lock design can be one factor. Set your code before travelling, press the zip pulls firmly into place, and test the release button once before you leave. This type is neat, secure for normal travel use, and easy to reset if needed.

Which travel lock should you choose?

Combination locks

A TSA combination lock suits most travellers because there is no separate key to lose. It is a strong all-round option for checked suitcases and cabin bags.

Cable locks and padlocks

Cable locks are useful when zip pulls are awkward or when you want a little more reach on a backpack or duffle bag. Small padlocks work well on cases with solid locking points. In most cases, the best luggage lock is a sturdy, compact model that fits your bag properly rather than the largest lock available.

FAQ about luggage locks

Is it worth putting a lock on your suitcase?

Yes, if you want a simple way to reduce casual interference and keep zips closed. A lock is not absolute protection, but it is still a practical addition to any trip.

Should you put locks on checked luggage?

Yes, but choose TSA-approved suitcase locks for checked bags. That lowers the risk of a lock being cut if security needs to inspect the case.

What is the best suitcase lock?

For most people, the best suitcase lock is a TSA-approved combination model. It is easy to use, avoids lost keys, and works well for both regular suitcases and many lockable travel bags.

TSA007 is not your code and not a feature you need to activate. It identifies one of the official access formats used by authorised security staff to inspect TSA luggage locks when necessary.
