No Key Detected Message
The No Key Detected message displays in the IPC message center when:
- When the ignition is OFF, the START/STOP button is pressed and a programmed passive key is not detected inside the vehicle. If a component failure (such as a depleted passive key battery or BCM failure) is causing the No Key Detected message to display, the backup starting method can be used.
- When the ignition is ON, the driver exits the vehicle with the programmed passive key and closes the door.
- The BCM activates the PATS center antenna and keyless entry rear antenna to search the inside of the vehicle for a passive key any time a door or the liftgate is opened and then closed with the vehicle running and the first times each drive cycle the vehicle speed exceeds 15 km/h (9 mph). 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 detected in the vehicle, the vehicle continues to run. If the START/STOP button is pressed to turn the vehicle off, the engine can be restarted without a passive key present inside the vehicle for approximately 20 seconds. After 20 seconds have elapsed, a passive key must be present to transition the ignition to ON.
The No Key Detected message displays in the message center when:
- the START/STOP button is pressed with the ignition OFF and a valid programmed passive key is not detected inside the vehicle.
- the engine has been started or the ignition is in RUN and a passive key is no longer detected inside the vehicle.
The BCM activates all the PATS antennas to search the inside of the vehicle for a passive key every time a door or tailgate is opened and then closed. This strategy aids to prevent the passive key from being separated from an already running vehicle. If a passive key is no longer detected in the vehicle, the vehicle continues to run. If the START/STOP button is pressed to turn the vehicle OFF, the engine can be restarted without a passive key present inside the vehicle for approximately 20 seconds. During that time, Restart now or key is needed displays in the message center. After 20 seconds have elapsed, a passive key must be present to start the vehicle or transition the ignition out of ON.
