The Car Access System (CAS) administers two different numbers for each remote control and for each spare key belonging to the vehicle.
The key code number is part of the key identification. As there may only be a maximum of 10 keys per vehicle, key numbers 1 to 10 are stored in CAS. Key code numbers cannot be changed. The key code number is transferred to CAS when the remote control is used. When the key is in the ignition, CAS reads the key number directly from the transponder (memory) in the key. Each key code number occurs only once in CAS. If required, a key can be blocked in CAS by using the key code number.
Personalisation numbers are required to read the Key Memory settings in the vehicle. When unlocking using the remote control, the remote control sends the personalisation number to CAS. CAS forwards the number to the other control units via the data busses. The control units then perform the settings saved in the Key Memory. A total of three different Key Memory settings are coded into each control unit. This means that the personalisation number can have a value from 1 to 3. If required, these can be transferred to another remote control. This is carried out in the personalisation number function.
The vehicle is delivered from the factory with two remote controls. A new remote control has the same key code number as the personalisation number.
This function is used to:
Replace/block a remote control.
Release blocked remote controls.
Program an extra remote control.
Blocking is recommended when a remote control or spare key has been lost or stolen. The engine cannot be started with a blocked remote control (or spare key). The remote control functions are also blocked. A remote control or spare key can only be blocked if the remote control or spare key is used at least once and is not inserted into the ignition. If a remote control is used instead of a lost or faulty remote control, the old one must still be blocked..
Important:
When retro-ordering more remote controls they must be activated in the correct order.
When retro-ordering more remote controls they must all be activated using the ring aerial.
Activating a new remote control/key: Insert the new remote control in the insertion socket and hold it in this position until the remote control clicks in place. This may take as long as 10 seconds. After it has clicked in place wait a further 5 seconds. The remote control is then ready for use.
When ordering a new CAS control unit and new remote controls, you must first fit the new control unit and then activate the new remote controls in the correct order.
Test conditions:
Ignition on.
Procedure:
Start the function.
Follow the instructions in the program.
The function is complete.
