How do I get my 2001 lincoln Navigator factory default code reset

You will have to have a dealer do this for you,

1. Make sure you know the factory-programmed door lock code (Master Code). Check the original documentation that came with the vehicle or look at the right-side gas spring arm on the rear hatch door or under the drivers side dash (up and to the left by the firewall). In both places, you should see white labels with the Master five-digit factory code printed on them. 2. Enter the factory-programmed five-digit code on the exterior keypad. 3. Press the "1-2" button on the keypad within five seconds of entering the last digit of the factory-programmed code. This initiates the code-setting mode for the personal code. 4. Enter your preferred five-digit code number. Make sure that you hit each button within at least five seconds of hitting the one before it, otherwise the code-setting mode will auto-cancel. 5. Watch and listen for the door locks to lock and then unlock in fast succession after you've entered the last digit of your personalized code. This is the signal that the new code was accepted.
