Keyless Entry Rear Antenna

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 keyless entry rear antenna is wired to the BCM. When activated by the BCM, it transmits a low frequency signal that activates a passive key.

When activated, the keyless entry rear antenna sends out a low frequency signal with an approximate range of 1 m (3 ft). A programmed passive key must be within range for the PATS to recognize the key and allow the ignition to transition out of off.

If a passive key is placed in the far outside edges of the interior, such as the far corners of the passenger compartment area, 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 and the PATS center antenna when the START/STOP button is pressed, the No Key Detected message displays in the message center.
