Abstract: Once the release switch is operated via the control unit in the car, a vehicle transmitter for the vehicle interior is triggered to send a passivation signal to an existing identification device (radio key device) in the vehicle. This signal prevents its further participation in authentication communication.

Vehicle remote-operation apparatus
Makoto Inoue
- 21 Feb 2006
TL;DR: In this article, a vehicle remote-operation apparatus is provided which transmits a regular authentication request signal from a vehicle outside antenna and simultaneously transmits an interference wave for negating this authentication request signals from inside antenna, so that the communicable range can be limited between a radio portable unit allocated an identification code unique to a vehicle and the vehicle-outside antenna.

Method for detecting portable transmitter left inside vehicle
Peter Paeschke,Walter Weishaupt +1 more
- 14 Jul 1992
TL;DR: In this article, a keyless access system for vehicles is proposed, in which the position of the transponder is detected and possibly a signal is triggered via a question/answer dialogue triggered during the locking, the dialogue is triggered when a locking command is issued and the locking is only carried out when the transping signal is detected outside the vehicle.
