Abstract
Access control equipment for vehicles with an electronic remote key which is accommodated in a housing, includes a controller that is designed for temporary activation of the remote key. The controller has an interface for wireless communication and is designed to cause an activation of the remote key in dependence on a wireless communication. A voltage supply is coupled to the controller and the remote key. The voltage supply, under actuation from the controller, applies an electrical breakdown voltage via at least one contact of the remote key for at least a first predetermined duration, which is greater than a designated operating voltage for the remote key, in order to destroy the remote key by the resulting current flow.
