Abstract
A jamming radio signal is outputted to interfere with an interrogation signal emitted by a vehicle for verifying a tag of a vehicle key that provides access to the vehicle. An access signal including access data is received. The output of the jamming radio signal is halted, at least temporarily, when the access data matches an access code so that the tag of the vehicle key can be authenticated.
