Abstract (en)

[origin: EP0816600A2] Single key system comprising a lock, keys and a codifier. The lock includes an electronic circuit (25) which stores an access code and identification codes for the keys with specific restrictions. Besides the lock, there is also a mechanism (22), to enable or prevent the cylinder (13) from turning, which is controlled by the electronic circuit (25). The keys include electronic circuits that store the access codes for one or several keys. The codifier enables the codes for the keys to be introduced, annulled or modified, with the possibility of one key including authorization to open several locks. <IMAGE>
