I have a 2000 MGM that has become my pride and joy since buying it just under a year ago. I've been lurking here since just before I purchased it (this forum strongly influenced my decision) for tips and tricks. Now I have one that I can't seem to find an instance of it having been answered before. I came home with a nasty sinus infection the other day and forgot to lock my doors before I went in the house (15 years in the security industry preaching this stuff to clients...). Some time over night the local hoodlums raided my car for goodies.  They got some unimportant stuff like my cellular headset and a couple of items I'd picked up at a garage sale, but they also took my user manual from the glove compartment. While I do miss having that cool Mercury emblazoned booklet in there, I'm more concerned that the factory unlock code card was in there. Having watched the neighbourhood kids for years I don't think that they're smart enough to come back again (and again) but I'd prefer not to take that chance. Has anyone ever had to change the security module in their car? I realize that the factory code isn't changeable but I presume that installing the module from another car may address my problem. Is this possible? Is is expensive? Am I grasping at straws?

Replying to: euphonium (Aug 13, 2006 7:41 pm) There is a factory code in a module that cannot be reprogrammed, but owners can overlay a 2nd code of their choice. (Certain combinations, however, are not allowed. And users are cautioned against using consecutive numbers, such as 12345, or all one number, such as 55555.) The factory code is printed on the module, but the module is placed in various locations on various models and model years. The code is a 5-digit numeral in larger/heavy print than other citations on the module. Several posts said you can buy replacement modules on eBay at a reasonable price. On several different threads, these Keypad Reprogramming/Programming Directions were posted (NOTE that I have not yet tried them), and the same steps allegedly work for all Ford products: ---------- Make sure when pressing the controls on the keyless entry keypad you press the middle of the buttons to ensure good contact with the controls. Programming Your Own Personal Entry Code 1. Enter the factory-set code (keypad will illuminate when first digit is pressed). 2. Press the 1/2 control within five seconds of step 1. 3. Enter your personal 5-digit code. Enter each digit within five seconds of the previous one. Your personal code does not replace the factory-set code. You can use either code to unlock your vehicle. Each time you set a new personal code the module will erase the previous one in favor of the new code. The factory-set code can not be erased. Erasing Your Personal Code or A Prior Owner's Code 1. Enter the factory-set code. 2. Press the 1/2 control within five seconds of step one 1. 3. Press the 7/8 and 9/0 controls at the same time within five seconds of step two. The system will now only respond to the factory-set code. Unlocking the Doors 1. Enter either the factory-set code or the personal code (Each digit must be pressed within five seconds of the prior digit). The interior lights will illuminate as soon as the first valid digit is pressed. 2. To unlock all the doors, enter the factory set code or a personal code and press the 3/4 control within five seconds of the drivers door unlocking. Locking the Doors 1. Press 7/8 and 9/0 controls at the same time. The 5-digit code does not have to be entered to lock the doors. Deactivating/Activating Auto-lock 1. Enter the five 5-digit code. 2. Press and hold 7/8 control. 3. Press and release 3/4 control while holding 7/8 control. 4. Release 7/8 control. The horn will chirp once if auto-lock was deactivated or twice if auto-lock was activated. ------------- Good luck!

Let us know how you make out with eBay, cyberwiz. And where the module is located on your GM when you find it. (A truck owner said his was behind the glove box. I couldn't find anyone who replaced a GM module.) Who knows when one of us will need to duplicate your work?

If it does, then maybe you haven't noticed the other locks releasing after pressing in their codes. The owners manual tells and gives direction on how to install a second code. We use that second code on both of our cars with pads. Code= wife's birthdate, that she knows. |
