Interior Passive Start Antenna Ranges

WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Some brands/types of mobile phone or laptop computer chargers may cause interference that could lead to a PATS no-start if the IA key is within a few inches of the charger and the NO KEY DETECTED message is displayed in the message center. If a concern is observed, move the IA key away from the charger and attempt to start the vehicle.

There are 3 passive start antennas that are used solely for the purpose of starting the vehicle. They are located in the front of the floor console, in the rear of the floor console, and under the liftgate scuff trim panel below the liftgate striker. When activated, each antenna sends out a low frequency signal with an approximate range of 1 m (3 ft). A programmed IA key must be in range of 1 of the 3 antennas for PATS to operate.

If an IA key is placed in the far outside edges of the interior, like above a sun visor or in a door map pocket, the vehicle might experience a no-start. If the IA key is located in one of these areas and there is a no-start condition, move the IA key out of the area and attempt to start the vehicle. If the key is outside the range of a passive start antenna, NO KEY DETECTED is displayed in the message center.
