Abstract

A method and apparatus teach a plurality of keys to an authorization device in a vehicle. The keys that are in a reception range of a transmission unit of the authorization device receive a test signal from the authorization device. The respective key ascertains a key-specific time window from at least one signal parameter of the test signal that is dependent on the physical location of the key, during which the respective key transmits a response signal that can be received by the transmission unit and recorded by the authorization device.
