Passive Key

NOTE: Some brands/types of mobile phone or laptop computer chargers may cause interference that could lead to a PATS concern if the passive key is within close proximity of the charger. If a concern is observed, move the passive key away from the charger and attempt to turn the ignition on.

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. See the Owner's Literature for maximum number of keys that can be programmed to the vehicle.

The passive key receives the low frequency signals from the PATS center antenna, the keyless entry door antennas and the keyless entry rear antenna. 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 RTM. 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.

The passive key also contains a removable key blade that unlatches the driver door in the event of an electrical failure (such as a drained battery). The passive key requires 1 battery. For battery replacement instructions, refer to the Owner's Literature.
