Master Lock 4689Q TSA Luggage Lock 4-Pack review

The Master Lock 4689Q is the value pick for groups: $23.99 buys four TSA-approved locks, about $6 per lock, the lowest unit price on this list. All four are keyed alike, so one key opens every bag, and Master Lock lists a 1 in (25 mm) metal body, a front access keyway and a steel shackle 9/16 in (14 mm) long and 1/8 in (3 mm) thick. The shrouded design covers most of the shackle, which Master Lock says minimizes exposure and protects against bolt cutter attacks, and the product page lists a Limited Lifetime Warranty. The drawbacks come with keys: if the key goes missing on a trip, every lock is affected, and the short shackle may not pass through chunky zipper pulls that the 4688D's flexible shackle handles. Master Lock also says each package holds locks of the same color. Travelers who would rather not carry a key should pick a combination model. We compared documented features and published prices and did not test the locks.
