Passive Key
The passive key incorporates both the PATS and the RKE transmitter functions into a single device. The passive key must be located inside the vehicle for the ignition to transition out of off and outside the vehicle for passive entry features. During key programming procedures, the PATS and the RKE transmitter of the passive key are both programmed into the RFA module. The vehicle accepts programming of up to 8 passive keys.
The passive key receives the low frequency signals from any of the 3 PATS antennas. When the passive key is activated by one of the low frequency signals, it sends out a high frequency signal that is received by the Radio Frequency (RF) receiver. The passive key also contains a removable key blade that unlocks the driver door in the event of an electrical failure (such as a drained battery).
