PATS Front Antennas

NOTE: Some brands/types of mobile phone or laptop computer chargers may cause interference that could lead to a PATS concern if the passive key is within a few inches of the charger and the "No Key Detected" message displays in the message center. If a concern is observed, move the passive key away from the charger and attempt to transition the ignition on.

The PATS front antennas are wired to the BCM. When activated by the BCM, they transmit a low frequency signal that activates a passive key. These antennas serves a dual purpose in that it can detect a passive key in the backup starting location. The backup starting location is used to program passive keys and to detect a programmed passive key in the event the battery in the programmed passive key has failed.

A programmed passive key must be within the passenger compartment or cargo area for the PATS to detect the passive key and allow the ignition to transition from off to on.

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 can experience a PATS concern. If the passive key is located in one of these areas and there is a PATS concern, move the passive key out of the area and attempt to transition the ignition on. If the key is outside the range of the keyless entry rear antenna, PATS front antennas, PATS center antenna, and PATS interior rear antennas when the START/STOP button is pressed, the "No Key Detected" message displays in the IPC message center.
