1. An electronic vehicle key comprising:
- a radio receiver for receiving radio call information which is transmitted by a control centre;
a key communication device for communicating with a vehicle communication device in an associated vehicle, signals transmitted by the key communication device to the vehicle communication device serving to activate or deactivate an immobilizer on the vehicle; and
a key controller provided in the electronic vehicle key for administering a mobility account, wherein use-enabling radio call information transmitted by the control centre is registered as a “
maximum credit”
in the mobility account;
relevant events are registered as “

Abstract
An electronic vehicle key has a radio receiver for receiving radio call information which is transmitted by a control center, and a key communication device for communicating with a vehicle communication device in an associated vehicle, signals transmitted by the key communication device to the vehicle communication device serving to activate or deactivate an immobilizer on the vehicle. According to the invention, a key controller, which administers a mobility account, is provided in the electronic vehicle key; and radio call information is transmitted by a control center is registered as a “credit” in the mobility account. Relevant events are processed as “debits” in the mobility account, and deactivation or activation of the immobilizer on the vehicle is dependent on the account value of the mobility account.
