"No Key Detected" Message

NOTE: Some brands/types of mobile phone, laptop computer chargers and other radio frequency interference 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 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 front antennas, PATS center antenna, PATS interior rear antennas and keyless entry rear antenna to search the inside of the vehicle for a passive key any time a door or the tailgate is opened and then closed with the vehicle running and the first times each drive cycle the vehicle speed exceeds 5 km/h (3 mph). The "No Key Detected" message displays in the message center and the horn chirps (when in park only) twice when the ignition is on and a passive key is no longer detected inside the vehicle.
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.
Key not in vehicle
Doors electrically disconnected, but still installed.

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.
