Abstract

A mechanical card-serviced lock comprises a housing (1), a locking member (2) which is displaceably arranged in the housing, blocking pins (12, 13) which by means of a key card (4) are mechanically movable between positions where they prevent and permit, respectively, relative movement between the locking member and the housing, and means (3, 18) for selectably changing the total length of the blocking pins in order to set the combination of the lock in correspondance with a key card (4) introduced in the lock.
