Abstract: A keyless entry system for a vehicle, in particular a motor vehicle, the keyless entry system including a device for unlocking at least one locked door of the vehicle in response to an electronic door opener being manipulated, and the device having at least one input element accessible from the outside of the vehicle. It is provided, that the door of the vehicle may be opened by inputting a code at one or a maximum of two input elements, the code being made up of a sequence of digital or quasi-digital signals, which are generated by alternately manipulating or not manipulating the input element(s).

Abstract: A device and a method for reproducing information in a motor vehicle include, as part of a keyless access system and/or drive authorization system, a portable transponder for sending a code via a transceiver to a control device arranged in the motor vehicle. Access authorization and/or drive authorization are granted if the control device receives a valid code. A display is arranged in the vehicle. The display displays specific data based on an output signal from the control device.

Abstract: A start/drive system for a vehicle includes a selector assembly having a drive/gear selector, a driver authority device, a security system and a lock. The lock provides an initial partial release and a subsequent complete release of the drive/gear selector. An initial movement of the selector triggers an authorization check in order to allow a further complete release of the selector.
