Abstract
A method implements keyless access to at least one vehicle door. An access system has at least one central control unit for transmitting and receiving control signals, at least one first door control unit which is assigned to a first vehicle door and has the purpose of unlocking or locking a vehicle door, at least one first proximity sensor for sensing an object located in the direct vicinity of the first proximity sensor, and a central check system which communicates with the central control unit in order to authenticate an opening signal of an identification signal transmitter. The first proximity sensor outputs a proximity signal when the object is sensed, so that the first door control unit is changed by the proximity signal from a first operating state into a second operating state.
