A process for operating a remote-controllable central locking installation of a vehicle by means of a transmitter, which can transmit coded signals--for example acoustically by means of ultrasound, optically by means of IR and/or by means of USW high-frequency waves--to a receiver fitted in or on the vehicle. An initialization is typically carried out before the actuation for the first time of the central locking installation, or a reinitialization is carried out before the next actuation of the same, to cancel the previous code, that is the code which can be used in future, or in the case of a changing code the relevant code set which can be used in future, being fixed for the first time or once again by the receiver being driven, for example by means of a special control code, into a state in which it can be (re)initialized. The receiver indicates that the receiver is ready for (re)initialization and/or after successful (re)initialization by means of an activation of the door locks.
A process for operating a remote-controllable central locking installation of a vehicle by means of a transmitter, which can transmit coded signals to a receiver fitted in or on the vehicle, an initialization being carried out before the actuation for the first time of the central locking installation, or a reinitialization being carried out to cancel the previous code, or in the case of a changing code the relevant code set which can be used in future, and to establish a new code or code set, by the receiver being set into a mode in which it can be (re)initialized, comprising the improvement that:
A process for operating a remote-controllable central locking installation of a vehicle by means of a transmitter, which can transmit coded signals to a receiver fitted in or on the vehicle, the vehicle having an ignition switch operated by an ignition key an initialization being carried out before the actuation for the first time of the central locking installation, or a reinitialization being carried out to cancel the previous code, or in the case of a changing code the relevant code set which can be used in the future, and to establish a new code or code set, by the receiver being set in a reprogram mode in which it can be (re)initialized, comprising the improvement that:
A method of initializing a remote controllable central locking installation for a vehicle having a remote transmitter and a receiver fixed to the vehicle and operatively connected to locks for doors of the vehicle, the receiver having electronic means for receiving and recording new instructions for recognizing future valid transmitter codes from a transmitter assigned to the vehicle when the electronic means is actuated to an initializing state, comprising the steps of:
