Airport TSA Approved for Checked Luggage

The TSA now suggests you lock your checked baggage with TSA accepted and recognized Travel Sentry® Approved locks.  This lock features the required Travel Sentry® mark that meets the requirements of the TSA.  Airline check-in staff are trained to recognize the Travel Sentry® mark so they understand that case and luggage locks with this special mark is permitted to remain locked. 

When you check a travel case at a U.S. airport, it is sent through an electronic screening process for inspection. If a TSA Agent needs to search it, the agent will use a federal government protected override device to open the TSA accepted SearchAlert lock. TSA employees no longer need to cut your locks or force the bag open and risk damaging it. They simply open your locks, inspect, and re-lock your bags, sending them quickly and securely on their way. 

Airport Approved In Most Countries

The Travel Sentry luggage security system is in use at hundreds of airports around the world. The system has been implemented at every U.S. airport including overseas territories such as the U.S. Virgin Islands, American Samoa, Guam, and Micronesia. Travel Sentry Approved locks are officially recognized and accepted by the US Department of Homeland Security's TSA and by Her Majesty's Revenue and Customs (HMRC) in the U.K.

What Makes This TSA Lock Different From Others?

When a TSA agent needs to check your luggage and uses their override device on the lock, the SearchAlert patented Security Window changes from green to red. After they re-secure the lock, they cannot reset the SearchAlert window and it will stay red in color. Once your case arrives in baggage claim, the SearchAlert feature tells you if the lock has been opened outside of your view, important if you check valuable and expensive gear.

If the locks SearchAlert window is "red" upon arrival, the traveler needs to open the luggage to see if a TSA Notification of Baggage Inspection has been placed inside.  If no notification is found the traveler should check to see if anything is missing or if something has been added to the travel piece.  This should be done at the Airline Baggage Claim office.

Love the metal construction and ease of use. Also like the indicator to tell me if someone accessed my stuff. Great product. Love the larger size.


After seeing a video of how easy it is to poke a pen into the zipper of a piece of luggage and steal your valuables when flying, I took the given advice and purchased an ATA approved case from SKB, which is actually a better, stronger, lighter case than the ones offered by Pelican. The video also mentioned how easy it is to snip or break the standard TSA locks, so I purchased two of these beefy locks for my case, which just arrived today. Corporate Travel shipped them to me within a couple of days, faster than my case, which just arrived today. The locks are beefy and easy to set your own combination and operate. The extra big loop makes it easier to thread through the lock holes on the case, and let the locks hang down nicely out of the way. The smaller standard padlock loop would probably have the body of the lock partially sticking out. I couldn't be happier with the lock or the amount of time it took to receive them once ordered. Now I know that my valuables will be safe as the combination of the locks and the SKB 2011-7 case will practically be a traveling safe. I heartily recommend these locks and Corporate Travel Safety.


I go on a lot of business trips and have been using this lock for some time now. It is durable and easy to use. Will be buying more soon.
