Disabling remote-control units 

Should a remote-control/key unit be lost, it is possible to disable it using the diagnostic interface.

First, the CAS Car Access System will need to read out data from all of the remaining remote-control/key units to determine which unit has been lost. It determines which remote key is missing based on the remote key numbers that are still present.

The selected remote control/key unit can be disabled using the "Disable/enable key" diagnostic service.

Should the remote-control/key unit be discovered again at a later date, it can be enabled again using the same process.

Emergency operation 

In the event of a failure in the central locking system, the vehicle can be unlocked and locked manually using the emergency key. (lock barrels on door and boot lid/tailgate as well as the locking storage compartment)
