Passive Entry
The passive entry feature unlocks or locks the doors or opens the luggage compartment lid 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 luggage compartment lid release button is pressed, it activates the low frequency antenna in the corresponding exterior door handle and inside the luggage compartment area. The low frequency antenna sends out a signal to the passive key. The low frequency signal activates the passive key and the passive key sends 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 programmed passive key, the BCM either unlocks the driver door, unlocks or locks all 4 doors, or releases the luggage compartment lid latch.
