Abstract:
A system with optical or radio remote control for initializing a system for locking and/or unlocking doors of motor vehicles, comprising:a portable transmitter corresponding to a key for a motor vehicle, said transmitter broadcasting a digital code upon actuation by a user for locking and/or unlocking doors of the motor vehicle;said broadcast digital code received by a receiver in the motor vehicle, which receiver controls a relevant lock or locks of the doors of the motor vehicle after a comparison and correlation of the received digital code with a predetermined code stored in the receiver;the digital code being initialized as the predetermined code at least when the motor vehicle is first used and, possibly when changes are later made to the digital code, being reinitialized, that is fixed for following actuations, by storing in the receiver the broadcast digital code as a new predetermined code that replaces a previous predetermined code, the broadcast digital code being also storable in the transmitter;an external diagnostic device for supplying at least an external signal for (re)initialization, that is for initialization and/or for (re)initialization, the receiver being switched only after reception of the external signal to a (re)initialization readiness status before the receiver is (re)initialized;the motor vehicle having a diagnostic interface for electrical testing of motor vehicle units in the motor vehicle, said diagnostic interface connected to said receiver; andthe receiver being switchable to the (re)initialization readiness status only after reception of the external signal fed to the receiver via the diagnostic interface from the external diagnostic device;wherein a new code signal is generated using the transmitter and is transmitted to the receiver, the new code signal then being stored as a new-predetermined code signal in the receiver.
