PATS Antenna Ranges

WARNING: This page is about a different car, the 2016 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

The PATS antennas are used solely for the purpose of starting the vehicle or changing the ignition states. When activated, each antenna sends out a low frequency signal with an approximate range of 1 m (3 ft). A valid programmed passive key must be in range of 1 of the 3 antennas for the passive key to activate.

If a passive key is placed in the far outside edges of the interior, such as above a sun visor or in a door map pocket, the vehicle might experience a no-start condition. If the passive key is located in one of these areas and there is a no-start condition, move the passive key out of the area and attempt to start the vehicle. If the key is outside the range of the PATS antennas when the START/STOP button is pressed, No Key Detected displays in the message center.
