Passive Entry

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

The passive entry feature unlocks or locks the doors or releases the tailgate latch without having to use a mechanical key blade or the RKE transmitter feature.

When the BCM detects a lock or unlock sensor is touched on an exterior door handle, or the tailgate release button is pressed, it activates the low frequency antenna in the corresponding exterior door handle or inside the tailgate. The low frequency antenna sends out a signal to activate the passive key. The passive key then responds by sending a high frequency signal back to the RTM. The RTM interprets the high frequency signal from the passive key and sends the information to the BCM. If the BCM detects a valid programmed passive key, the BCM either unlocks the driver door, unlocks or locks all doors, or releases the tailgate latch.

Door Passive Entry 

With a valid programmed passive key within 1 m (3.28 ft) outside a door, touch the lock or unlock sensor on the exterior door handle. The doors lock or unlock depending upon which sensor was touched on the handle. The unlock button is located on the inside of the handle and the lock button is located on the outside top face of the handle.

The driver front door passive entry feature either unlocks the driver door (if 2-staged unlock is enabled) or all four doors (if staged unlock is disabled). The passive entry feature always locks all the doors when the lock button is touched.

The passenger door passive entry feature always locks or unlocks all the doors.

Tailgate Passive Entry 

With a valid programmed passive key within 1 m (3.28 ft) outside the tailgate, press the tailgate release button on the underside of the tailgate handle to release the tailgate latch.
