Pacsafe Prosafe 1000 Travel Sentry Approved Combination Padlock vs Master Lock 4688D Set Your Own Combination TSA Lock

Which should you buy? Our verdict on both, pulled from our full Which TSA Luggage Locks Are Actually Worth Buying? comparison.

The Pacsafe names its inspection system, lists a deadbolt mechanism and materials, and carries a 2-year accessory warranty. The Master Lock costs less and its flexible cable shackle fits awkward zipper pulls, but Master Lock itself classes it as basic security.

Buy it

A sturdy, clearly documented Travel Sentry padlock with a deadbolt mechanism and a 2-year accessory warranty.

  • Pacsafe names it as Travel Sentry Approved, which is one of the two systems TSA holds master keys for.
  • It lists a deadbolt locking mechanism and a 3-dial resettable combination.
  • Materials are stated as zinc alloy and plastic with stainless steel, and Pacsafe gives a 2-year warranty on accessories.
  • At 3 inches tall and 0.16 pounds it is the largest and heaviest lock here.
  • A rigid shackle can be harder to fit through small or tightly spaced zipper pulls than a cable.
  • Three dials give 1,000 combinations, the same as most TSA locks, so it is still a deterrent rather than high security.
