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 programmed passive key is not detected inside the vehicle. If a component failure (such as a dead passive key battery) is causing the No Key Detected message to display, the backup starting method can be used.
The second scenario is when the vehicle ignition is on, the driver exits the vehicle with the programmed passive key and closes the door.
The BCM activates the PATS center antenna, the keyless entry rear antenna and both exterior door handle keyless entry antennas to search the inside of the vehicle for a passive key any time a door is opened and then closed with the ignition on and the first time 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 an already running vehicle. 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 passive key must be present to transition the ignition out of off.
