Built-in combination locker locks use a combination to open and are resettable, so they're ideal for settings where the lockers regularly change hands, like schools. They may also be accessed with a control key if the combination is forgotten or unknown. These locks secure access to the locker's contents and don't require users to keep track of locks or keys.

Built-in keyed locker locks open with a key and have a pick-resistant tumbler cylinder, making them more secure than combination locks. These locks secure access to property in horizontal and single-point ventilated and open mesh lockers in schools.

Built-in multiuser locker locks can be reset each time they're used, so they're ideal for lockers that are used by different users at different times. Users set their own combinations, and once they've finished using the locker, it's left unlocked and ready for the next user. If the combination is forgotten or unknown, the lock can be overridden with a control key. These locks secure access to property in lockers in gyms, health clubs, and spas and don't require users to keep track of locks or keys.
