Passive Anti-Theft System (PATS) - Overview
Overview
The PATS deters the vehicle from theft by preventing the vehicle from starting unless a valid programmed key is detected inside the vehicle when the START/STOP button is pressed.
The PATS does not disable an already running vehicle.
No Key Detected Message
There are 2 scenarios in which the No Key Detected message displays in the message center.
The first is when the ignition is off, the START/STOP button is pressed and a valid programmed passive key is not detected inside the vehicle. If a component failure (such as a depleted passive key battery or RTM failure) is causing the No Key Detected message to display, the backup starting method can be used.
The second scenario is when the ignition is ON, the driver exits the vehicle with the programmed passive key and closes the door.
When a door or the liftgate is opened and then closed with the vehicle running and the first time each drive cycle the vehicle speed exceeds 15 km/h (9 mph), the inside of the vehicle is searched for a passive key. The No Key Detected message displays in the message center and the horn chirps twice when the ignition is on and a passive key is no longer detected inside the vehicle.
This strategy deters the passive key from being separated from a vehicle with the ignition ON. If a passive key is no longer in the vehicle, the ignition remains on and the vehicle continues to operate. When the START/STOP button is pressed to turn the ignition off, the ignition can be restarted without a passive key present inside the vehicle for approximately 20 seconds. After 20 seconds have elapsed, a valid programmed passive key must be present to transition the ignition out of off.
Backup Starting
When the BCM does not detect a valid programmed passive key in the passenger compartment, the No Key Detected message displays in the message center when the START/STOP button is pressed.
In the event this message displays, place a programmed passive key in the backup location to allow the vehicle to start. The passive key must be oriented correctly in the backup starting location.
Refer to the Owner Literature for the passive key backup starting location.
