An Overview On TSA Locks

All checked luggage is screened by the TSA before it is loaded onto an airplane. If a suitcase seems suspicious for any reason, an agent will open it up to review its contents. Since you won’t be with the suitcase at the time of the screening, the agent needs a way to get into the bag. That’s where TSA locks come in. Agents are able to open these locks. Anyone who opts to go with a traditional lock risks having the lock cut off if the TSA agent decides to take a peek inside.

There are two types of TSA locks. You can opt for a key lock or a combination lock. Key locks can be opened rather quickly, but if you lose your key, you won’t be able to open your luggage. Individuals who tend to misplace items regularly may want to go with a combination lock instead. You will, of course, need to memorize your passcode to open the lock.

If you do opt for a combination lock, you may want to go with a four-digit lock instead of one with only three digits. A four-digit lock is 10 times harder for thieves to crack, as there are over 10,000 possible combinations.

Always review the lock’s construction material. It needs to stand up to harsh handling. Bodies made of zinc alloy are strong and durable. Look for stainless steel cables and internal mechanisms, as they are resistant to rust and won’t freeze up in cold temperatures.

Another feature associated with TSA locks that you’ll want to keep an eye out for is an indicator button. This button pops up when a TSA agent uses their key to open the lock. There are also models that require the TSA agent to relock the device before they can pull their key back out. That ensures your luggage continues to be protected as it heads to the plane.

The TSA Lock Buying Guide

  • Although TSA locks will deter some thieves, it is possible for anyone to use a wirecutter to remove them if they really wanted to get into your bag.
  • Combination digits that are tiny and shiny are hard to read quickly. You’ll want to look for models that have white numbers with a contrasting black background.
  • You can use TSA locks on more than just your luggage set. They work great on gym lockers, briefcases, golf bags, book bags and gun cases.
  • If you like a little pop of color in your life, you’ll be excited to learn that TSA locks come in bright colors like orange, blue, purple and green.
  • TSA locks are pretty inexpensive, and you’ll find prices vary by only a few dollars. You can, however, expect to pay slightly more for a model that offers a four-digit combination instead of a three.
