No Key Detected Message

NOTE: Some brands/types of mobile phone or laptop computer chargers may cause interference that could lead to a PATS no-start 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 start the vehicle.

The No Key Detected message displays in the message center when:

The BCM activates all the PATS antennas to search the inside of the vehicle for a passive key every time a door or liftgate 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.
