Abstract
A switch is interposed between an ignition antenna associated with a vehicle ignition switch and an auxiliary antenna located spaced from the ignition switch. A reader is selectively connected through the switch to either the ignition antenna or to the auxiliary antenna, the reader configured to determine if an authorized key is present adjacent to an antenna. An authorized key is kept adjacent to the auxiliary antenna. The vehicle ignition switch can be operated either with an authorized key brought adjacent to the ignition switch and adjacent to the ignition antenna or by adjusting the switch to connect the reader to the auxiliary antenna to read the authorized key kept adjacent thereto. A controller can cause this switch to adjust from connecting the reader to the ignition antenna to connecting the reader to the auxiliary antenna, so that the controller can automatically cause vehicle ignition operation when desired.
