Remote control for central locking system

The remote control is used to operate the central locking and various additional functions.

The radio signals from the remote control are received by the remote control receiver and transferred to the CAS control unit.

Radio transmission of the remote control commands is encoded using a rolling code. This encoding rules out any possibility of manipulation.

The CAS manages the rolling codes of up to 10 remote controls.

During the vehicle unlocking procedure, the rolling code stored in the remote control is sent to the CAS. The CAS assigns a personal ID code to every remote control.

The CAS can assign up to 4 personal ID codes. If there are more than 4 remote controls, personal ID codes are assigned more than once. Which personal ID code is assigned to which remote control can be chosen at will.

The personalization number controls the defaults encoded in the key memory. The CAS transfers the personalization number to the control units on the data buses. The settings for the key memory are stored in the relevant control units.
