Front PATS Antenna
If the battery inside the passive key is weak, damaged or if excessive ambient Radio Frequency Interference (RFI) prevents communication between the RTM and the passive key, the backup slot located in the center console storage compartment provides a secondary means for the BCM to validate the passive key and authorize the use of the vehicle. The front PATS antenna uses passive Radio Frequency (RF) identification to exchange signals with the passive key.
