Passive Key

The passive key incorporates both the PATS  and the RKE  transmitter functions in a single device. The passive key must be located inside the vehicle for the ignition to transition out of off and on the outside for keyless entry features. During key programming procedures, the PATS  and the RKE  transmitter of the passive key are both programmed into the BCM  and the RFA  module. The vehicle accepts programming of up to 4 passive keys.

The passive key receives the low frequency signals from the 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 Remote Functions Receiver (RFR) module. 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).
