Abstract (en)
[origin: ES8703565A1] A system for the locking and/or unlocking of a security device, particularly an automobile locking device, comprising a transmitting device for transmitting coded data recording, a receiving device for receiving the coded data recording, a transmitter-end storage and a receiver-end storage for storing codes and a comparator for comparing the received data recording with the stored data recording, a control signal being adapted to be given off to the security device from the receiving device in the event that said data agree. The receiving device has a signal generator to produce several further coded data which are stored in the transmitting device and in the receiving device and can be employed upon the subsequent use of the system. The further coded data recording may be random number and/or algorithms for changing the random numbers. The production of the further coded data recording is effected preferably upon actuation of the ignition lock.
