WARNING: This page is about a different car, the 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

A unique personal 5-digit code can be programmed by following these steps:

  1. Enter the factory set 5-digit code (the RKE keypad will illuminate when pressed).
  2. Press the 1/2 button within 5 seconds of Step Β 1.
  3. Enter the unique 5-digit code.

The personal code does not substitute for the permanent factory set code. Either code can be used to access the vehicle. In addition, if a second personal code is programmed, it simply overwrites the previous personal code.
