A system for selectively coding a key to correspond to the code for any one of a number of differently coded locks is provided whereby the key is set to operate any given one of the locks. The key includes settable bits carried upon a shank or stem each of the bits being variously settable to a number of coded arrangements thereof. The key setting means serves to set the bits of the key in response to a coding element having predetermined code portions defining the code for the lock which is to be operated. For example a punched hole accounting card can be utilized as a coding element. The setting means receives a key and also the coding element and includes sensing portions for sensing the coded portions of the coding element so as to set the key bits in response thereto.
