Blocking/enabling remote keys and ignition keys

It is possible to electronically block or enable individual remote keys or ignition keys using diagnosis (service functions).

IMPORTANT: Electronically blocked means that both the starter and the engine control unit are not enabled for starting. It must be noted that an electronically blocked ignition key still fits mechanically, i.e. lids and doors can still be opened.
