code lock
Dial-operated fastener
A code lock is a lock opened by entering a sequence of numbers, letters, or symbols rather than using a physical key.
The term covers both mechanical combination locks with rotating dials and electronic keypads: Enter the code to unlock the door.
Code locks appear on safes, doors, luggage, and bike chains.
