Which luggage locks are best?

It is a federal law that Transportation Security Authority baggage screeners have access to your luggage so they can open it and inspect it. If your lock is not approved for travel by the TSA, baggage screeners will cut it off, rendering it useless.

All TSA-approved locks are designed so they can be opened by special tools, codes and master keys held only by TSA baggage handlers. If you are looking for a TSA-certified luggage lock that uses a steel cable and opens with a numerical code, take a look at the Travelmore TSA Approved Combination Cable Luggage Lock.

What to know before you buy a luggage lock

TSA approval

If you plan on checking your locked luggage when you fly, you must have a lock that is approved and certified by the TSA as one they can open with their special tools. TSA-approved luggage locks are easily identified by a special red logo printed on the lock itself.


Shackles are padlocks with metal bodies and a U-shaped loop of solid steel. They are unlocked via a key or a combination. The shackle is the movable portion attached to the inside of the lock body. Shackles come in different lengths, so choose a lock long enough to connect the pieces you want locked together. Closed shackle luggage locks are more secure than the standard type you see people using on bicycles and school lockers.


This type of luggage lock has a flexible woven metal cable you thread through zipper heads to keep people from opening your luggage. Because cables are narrower in diameter than shackles, they are often used in light-duty applications.


This uniquely shaped luggage lock opens with a key or combination. The cable is a straight stem, not the typical design where the cable loops around and inserts into the lock body like a shackle does. The cable has a wide flange attached to one end and unlocks from the barrel at the other for inserting through zipper heads. 


 heavy-duty adjustable nylon straps

Another alternative to locks that slip through zippers is heavy-duty adjustable nylon straps with quick-connect TSA lock buckles. The locks are operated by combination. The crisscrossing straps are stretchable elasticized nylon with a nonslip silicone pad.


TSA-approved tamper-evident seals

Some manufacturers sell TSA-approved tamper-evident seals. These look like small plastic zip ties and cable bundlers. Like locks, TSA baggage handlers open these seals with special tools. The nature of this device is more of a seal than an actual lock.

What to look for in a quality luggage lock

Key vs. combination

Combination locks are easy to use but you have to remember the numbers. Key locks are also easy to use but you’d better not lose your key ring. If you see yourself losing your combination or your keys, choose a light-duty luggage lock you can disable yourself with simple household tools.

Lock sets

You can buy TSA-approved luggage locks individually or in packs of two to six locks. It is a good idea to have a spare luggage lock in the event of a malfunction while you are packing for a trip.

How much you can expect to spend on a luggage lock

TSA-approved luggage locks made with the most common shackle or cable styles start at $10 or less each, as do single locks with keys or combinations. The highest prices for sets of luggage locks are about $25.

Luggage lock FAQ

Is any luggage lock entirely safe?

What if you want a luggage lock but don’t fly on commercial airplanes?

A. If your luggage will not be going through TSA screening, your lock does not need to be TSA approved.
