Interior Passive Start Antenna Ranges

WARNING: This page is about a different car, the 2013 Ford Explorer. 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 Intelligent Access (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 Intelligent Access (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. When activated, each antenna sends out a low frequency signal with an approximate range of 1 m (3 ft). A programmed Intelligent Access (IA) key must be in range of 1 of the 3 antennas for PATS to operate.

If an Intelligent Access (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 Intelligent Access (IA) key is located in one of these areas and there is a no-start condition, move the Intelligent Access (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.
