Align the dials to the existing code, press or push the reset button into its groove, hold the button while choosing the new combination, then release the button to save the new code.

The most common mechanisms are pin-tumbler key cylinders, warded keyed locks, and keyless combination dials.

TSA-accepted locks are labeled as such and let Transportation Security Administration screeners open, inspect, and relock checked bags without breaking the lock. Some models also include an open-alert indicator that shows whether an inspection occurred.

Common materials include hardened steel (often for shackles), iron, zinc alloy or other metal bodies, and vinyl-covered braided steel cables for flexible models.

Many locks offer water-resistance and rust-resistance. Some combination locks also include an open-alert indicator that signals if luggage was inspected.

Baggage locks are sold individually and in multi-packs. Options range from single-unit packages to multi-packs such as a 12-pack of small keyed locks.

Very small locks—about 0.7 x 1.2 x 0.25 inches (roughly 1.2 inches high) with short shackles—are ideal for zipper pulls and securing small containers like jewelry boxes or diaries.
