Abstract
The publication relates to a lock system of the type which may be activated and/or recoded by means of a preferably plate formed key and/or recoding unit. The publication relates also to a method for recoding such system and to a key member for recoding the system. The lock system comprises a reading unit reading the code on the key and/or recoding unit, a unit comparing and memorizing the detected code and means for activating the mechanical parts of the lock thereby suspending its locking effect. The purpose of the system is to enable recoding of lock independent of a priority determined sequence of codes on the key and without being dependent of a centrally arranged memorizing unit, memorizing the various codes in sequence. The proposed effects are achieved by including a code section on the key member on to which a recoding command may be recorded. The recoding command is recorded on the key member in a central unit where a correct command for the lock in question is recorded on the recoding section of the key.
