Which TSA-approved lock is best?

Whether traveling by train from New York to Boston or on a long-haul flight to South Korea, it’s always best practice to take additional security measures with your luggage. It’s not only to prevent thieves from easily picking your bulky Master Lock, but also to ease your mind, knowing that the Transportation Security Administration won’t break the lock if they need to go through your bags. 

Each TSA-approved lock has several identifiable features that you should look for. For example, the best TSA-approved lock, the compact TravelMore Combination Lock, has the required red logo and easy-to-read dials. 

What to know before you buy a TSA-approved lock


You can find varying types of TSA-approved locks for sale, and it’s really a matter of personal preference which one you should buy. However, like TSA-approved travel bottles, they must fulfill specific requirements to be accepted. Some of the varying types include ones that open with a combination, key or pin. 

A combination lock on luggage isn’t like the bulky ones you’d find on school lockers. Rather, there are dials that turn instead of the ones that spin. Since each dial only goes up to nine digits, there are only a limited number of combinations that a thief would have to attempt in order to access the bag’s contents. So if you decide to go with a combination lock, look for ones that offer at least three to four separate dials. 

Next, you’ll come across key locks. These use a key that looks like a miniature version of the one for your front door. Because of their size, these keys can be easily lost, but manufacturers typically sell these locks with at least two sets of keys. 

Similar to a key lock, you have locks that open with pins. The only difference between the two is the tool. 


Many locks market themselves as TSA-approved but aren’t. Using an unapproved lock increases the chance that the TSA will have to break the lock, leaving your bag unsecured. 

Safe Skies and Travel Sentry are the two main companies that manufacture approved locks. These ones must have a red torch or a maroon diamond that signals to the TSA officer checking your bag that they can easily use their universal key to open it instead of breaking it and rendering it useless. 

Multiple unlocking methods

If you purchase a lock that only opens with a combination or key, you can run into trouble. A combination can get quickly forgotten and a key misplaced. Unfortunately, most TSA-approved combination locks can’t be reset if you ever forget the number. You’ll have to cut off the lock and purchase a new one. Luckily, these locks are relatively inexpensive, so it’s not a major problem if you ever forget your combination.

However, if you purchased a lock with both a key and combination option, even if you forget the combination, you can still use the key. But best practice is to take note of your combination and place it in a safe space if it’s a lock that can’t be reset. 

What to look for in a quality TSA-approved lock

Travel sentry symbol

One of the reasons to use a TSA-approved lock is that they don’t have to break it if your luggage needs to be searched. The most important thing to look for on any lock is the Travel Sentry symbol. This symbol alerts the agent searching your bag that it can be opened with their issued universal key. 

Compact but sturdy

The best TSA-approved locks are compact and sturdy. Size and shape are important: You don’t want the lock to hook onto the handles of other luggage and cause damage. While the locks may be small, high-quality ones are rugged enough to handle the harsh treatment your luggage goes through to get to your destination. 

If you decide to go with a lock that’s not approved, be aware that sometimes the mechanisms within can freeze during travel. 

Alert feature

An excellent feature to look for on an approved lock is the Search Alert indicator. Typically, they come built-in, and a red indicator pops up when a TSA agent uses their universal key. You may also find locks with a built-in indicator that shows up as a green block when it’s locked but turns red when opened. 

How much you can expect to spend on TSA-approved locks

TSA-approved locks are relatively inexpensive, and you can expect to pay between $8 and $30. 

TSA-approved lock FAQ

How can you tell if a lock is TSA-approved?

A. The TSA works with two companies, Safe Skies and Travel Sentry, that provide them with universal keys that allow agents to open the lock without cutting through it. Typically, the first sign that a lock is TSA-approved is the red torch logo for Safe Skies, or the maroon diamond that signals the lock is a Travel Sentry product. Other than that, the packaging should also state that it’s TSA-approved.

How does the TSA open these locks?

A. All approved locks have a particular keyhole at their bottom only accessible with the universal key given to TSA agents. The unique red logo alerts the agents that they can use the key to open and relock your luggage instead of cutting it off.
