The question is that how to change the factory keyless entry code? These methods are to put a NEW PERSONAL entry code not to replace the FACTORY CODE. So please tell us how to CHANGE the FACTORY keyless entry code. If someone could help it would be appreciated. Thanks,,
I followed the instructions to find the factory code behind the fuse box. Yes, that was a pain. But that code does not work. The 8-9 buttons DO lock the car, so I presume the mechanism still works. If the previous owner had personalized the code, the factory code should still work, should it not? And since it doesn't, what is my next step?? Trying to avoid paying $ 150 to the dealer. I am working on this for a 78 year old woman who manages to live on $800 per month, and has nothing to spare.
Thanks In Advance!!

Door pad keyless codes?
in owner manual, enter permanent code and then press "1" and enter personal code, then press "1" again. Then both codes will work.
If you don't have manual, go to Motorcraft.com and click on technical resources and click on your year owner manual.
---------------------------------------------
Each vehicle equipped with a keyless entry keypad is programmed with a five-digit entry code. This code is provided to the customer through a wallet card in the Owner Literature package. In addition, this code is available through a diagnostic tool and is also printed on the vehicle security module label. When entering codes each digit must be entered within five seconds of the previous button press.
Programming/Erasing Personal Code
A unique personal five-digit code can be programmed by following these steps:
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 will simply overwrite the previous personal code. To erase a personal code, carry out the following procedure:
The system will now only respond to the factory set code.
Anti-Scan Feature
To provide added security, the keyless entry pad is disabled for one minute after 35 button presses without a valid entry code being entered. The keypad will flash during this one-minute mode with all functionality disabled except for 7/8 and 9/0 still being allowed to lock the vehicle.
Anti-Scan will be turned off after any of the following events:
