ABSTRACT:
Recodable electronic lock where the coding unit which contains the code and/or other readable information preferably is removed from the lock after the recoding operation. The lock is coded by help of input of information and brought to accept recoding to any code member in a series of code members and is valid until a new, previously not utilized code member in this series is introduced whereupon the lock is automatically recoded to this new code so that the previously employed code member(s) are no longer accepted. The lock is then recoded to accept a new code series by employment of a new appropriately coded recoding member which contains readable information about the code(s) of the different code members in the new series. The potentially valid code series are stored in a memory unit in the lock.
