Passive Entry

The passive entry feature unlocks or locks the doors or opens the liftgate/luggage compartment lid without having to use a mechanical key or a RKE  transmitter feature.

When the RFA  module detects that a lock or unlock sensor is touched on an exterior door handle or the liftgate/luggage compartment lid release button is pressed, it activates the low frequency antenna in the corresponding exterior door handle or inside the rear bumper cover. The low frequency antenna sends out a signal to the passive key. The low frequency signal activates the passive key which then sends a high frequency signal to the Radio Frequency (RF) receiver. The Radio Frequency (RF) receiver interprets the high frequency signal from the passive key and sends the information to the RFA  module. If the RFA  module detects a programmed passive key, the RFA  module either unlocks the driver door, unlocks/locks all 4 doors or releases the liftgate/luggage compartment lid latch.
