Many TSA-accepted locks use zinc-alloy bodies and hardened or steel shackles; some cable-style locks use a vinyl-covered braided steel cord.
These locks typically use a 3-digit combination—commonly advertised as offering up to 1,000 possible codes (some descriptions may simply say 'hundreds' of combinations).
Align the dials to the current code, press and hold the reset button, set the new combination, then release the reset button to save it.
Cable-style locks in these descriptions use a vinyl-covered braided steel cable about 5.6 inches long.
Product details commonly list water-resistant and rust-resistant as protective qualities.
Descriptions say the locks work on most zippered luggage and backpacks and are suitable for both checked and carry-on luggage, as well as lockers at stations, schools, gyms, and water parks.
Some locks include an open-alert indicator that shows whether the lock has been opened, which can signal an inspection. Check the product details or the lock itself to see if it has this feature.
