How do I use my Lincoln's Phone As A Key™* backup start passcode?

If you are unable to start your vehicle with Phone As A Key, follow the steps below:

  1. Press the brake pedal and the ignition button. If the system does not detect a valid Phone As A Key, the system will prompt you for your Backup Start Passcode.
    • Make sure you have Phone As A Key active on at least one phone so that you can use the previously created Backup Start Passcode.
    • If the Backup Start Passcode screen does not appear, press the ignition button again.
  2. Enter your Backup Start Passcode on your vehicle's SYNC®** screen.
  3. Press enter within 30 seconds.
  4. Once the system validates the Backup Start Passcode, a message will alert you to start your vehicle.
  5. Press the brake pedal and the ignition button within 20 seconds to start your vehicle.
  6. If your vehicle does not start, repeat steps 1-5.

System Lockout

The system will lock after five attempts of trying to enter a Backup Start Passcode, resetting a current passcode, or entering an incorrect Valet Mode passcode.

The system will remain locked for five minutes. Try entering the codes again after five minutes.
