Spare key with adapter

A spare key with an ignition-lock adapter is also furnished with the vehicle. The spare key consists of a mechanical key bit along with an integral transponder, and is substantially smaller than the remote-control units.

The spare key offers the same functions as a remote-control unit:

• Access and driver authorization for the vehicle
• Transponder functions for the EWS electronic vehicle immobilizer
• Individual encoding

An adapter is needed to insert the narrow, flat spare key in the ignition lock and lock it in place. Because the adapter is only required for starting, it can be stored within the vehicle.
