Most TSA luggage padlocks have metal bodies, commonly zinc alloy, as shown in the product listings.

They include mechanical pin-tumbler mechanisms and user-set 3-digit combination dials; listings describe both pin-tumbler operation and 3-digit dial-style combinations.

Customers commonly report they’re straightforward to set up and use—including changing combinations—and product details typically describe a simple reset/setup mechanism.

Many listings highlight travel-oriented protections such as water-resistance and rust-resistance, and some note vinyl-covered cables or protective bodies intended to resist damage from baggage handling.

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

Options include single-lock packages and multi-packs; one listing explicitly describes a 4-pack that includes a user manual.

Some locks include an “open-alert” indicator or similar feature noted in product listings; this indicator shows whether security agents have opened and inspected the lock.

A 3-digit dial-style TSA luggage lock offers about 1,000 possible combinations.
