No Key Detected Message

2021 Ford Edge SE, 4WDSECTION No Key Detected Message
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Some brands/types of mobile phone or laptop computer chargers may cause interference that could lead to a PATS concern 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 turn the ignition on.

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.
