Method to limit interference to passive start and entry systems
First Claim
1. A passive start and entry system for a vehicle including an accessory power outlet disposed within an interior cabin, said passive start and entry system comprising:
- an electronic control unit for authorizing operation of desired functions responsive to receipt of a valid identification signal; and
a first antenna for transmitting a prompt signal disposed within the interior cabin of the vehicle.

Abstract
A vehicle passive start and entry system includes a controller that sends signals through a low frequency antenna to an identification device. The low frequency antenna is disposed within the vehicle cabin and proximate a source that generates extraneous electronic noise that may interfere with the transmission between the passive start and entry system and the identification device. Placing the low frequency transmitting antenna proximate these noise generating devices and locations prevents and provides for a uniform consistent and uninterrupted signal between the passive start and entry system and the identification device.
