Disable remote key
The service function 'Remote key lock/enable' in the BMW diagnosis system can be used to lock or enable remote keys, ID transmitters or spare keys.
It is recommended that a remote key is disabled if it is lost or stolen. Engine start is not possible with a disabled remote key. The functions of the remote control buttons are also locked.
A remote key can only be locked if it has been used at least once and has not currently been authenticated by the CAS control unit as a valid key.
To run the service function, it is required that CAS control unit has currently detected a valid and enabled remote key.
