Exterior Front Door Handles

WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.

Each of the exterior front door handles contain a keyless entry antenna. The antennas are wired to the BCM. When activated by the BCM, the antenna transmits a low frequency signal with an approximate range of 1 m (3 ft) to activate a passive key.

If a passive key is placed in the far outside edges of the interior, such as the far corners of the luggage 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 determined by the BCM to be outside the vehicle or is outside the range of the antennas within the exterior front door handles, the keyless entry rear antenna and the PATS front antenna when the START/STOP button is pressed, the No Key Detected message displays in the message center.
