Spare Key Programming
WARNING: This page is about a different car, the 2013 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The customer spare key programming allows spare keys to be programmed (up to a maximum of 8) to the BCM without having to use a scan tool. Two programmed keys are required to carry out the procedure. This procedure can be disabled so that spare keys can only be programmed to the vehicle using a scan tool. Refer to KEY PROGRAMMING - PROGRAM A KEY USING TWO PROGRAMMED KEYS for the customer spare key programming procedure or KEY PROGRAMMING - ENABLE/DISABLE SPARE KEY PROGRAMMING for the enable/disable procedure.
