    How do I get the key code from a 92 MTX? There are no stickers in the trunk, inner door jam, under hood, anywhere?????

    The most common place for the sticker to be is in the trunk on the control module. You'll need to pull the cover thing (that covers the amps) away from the seat and locate the box. It should be on the driver's side mounted to the back of the seat IIRC.

    Other places it could be are:
    1) On the owner's wallet card
    2) On a sticker in the lower left corner of the Owner Warranty Card

    And if you can't find the sticker open the control module and look at where all the little resistors are soldered and you can figure out the code. That's what I ended up having to do. It sounds like a pain but it's pretty easy.

    The top resistor determines the first number, and each successive number is determined by the next resistor down, so the last number is determined by the resistor closest to the IC. Here is how the resistors determine the code. On the right side of the resistors are five possible solder points. The solder point closest to the right of the card is for number 1/2 the next one to the left is for 3/4, then 5/6, 7/8 and finally 9/0. Below is an example drawing with a factory code of 31936.

    Here is the card you are looking for inside the keyless entry box:

    Here is the resistor layout that will give you the code:

    I recommend Sticky status on this for all to see. Really good information above.

    Also, theres no doubt that you can find a control box in the junk yard that IS labled.

    This way, you can change your code so the Previous Owner can't get in with the code he/she knows.

    I got mine from a supercoupe that had the sticker on the box.

    I have the complete document on changing the code step-by-step. If Bizzy wants to make it a sticky I can either send her the DOC or I can post it in a new thread.

    This is perfect just the way it is and I can absolutely sticky the thread. With your permission, I'd like to save the image you posted on the forum server. That way if anything ever happens to your image host the image won't go away.

    I'd also like to add some additional information about adding a personal code. I got the info from SHOTimes a long time ago, but not everyone surfs there anymore in spite of it being a great source for information.

    To add a personal code to your keypad what you do is input your current 5 digit code, then press the 1/2 button. Then within 5 seconds, input your own personal 5 digit code. This new personal code will do just as the programmed code does, except for some folks it will be an easier number to remember. One note though, you must have the current programmed code in order to input a personal code. It doesn't over-ride the programmed code either, you can use either one you like. Personally, I like being able to input something easier for me to remember. :thumb:

    Yes you have my permission to save the pics although I have to give to credit to Bruce Klein as it is his information. Here is the link to his write-up: http://webpages.cwia.com/~bdklein/sho.htm

    What if you know the car had the capability (you know the code and where it is located) but there is no number pad on the driver door (collision?) ? If you swapped on a door with the number pad would the code work?

    The code follow's the box in the trunk. You can swap key pads any time.

    resetting the factory preset that activates the relock

    Is there anyway of rewiring the control box inorder to defeat the preset (7/8-9/0) buttons which are used to relock the doors. My pads 9/0 botton isn't working properly so if the preset can be rewired to work with a different pad number it would save me the hassel of replacing the keypad on the door.

    Thanks

    it should still work with the car on; I have locked the car with the engine running and used the keypad to open it back up. It irks the living hell out of anybody that's locked their keys in their car before.

    Anyway, it seems that something isn't working with your system; does the car have electrical power? Also, can you turn the key in the ignition? If so, removing the whole lock cylinder is a moderately easy proposition; simply get a long skinny object - there's a hole on the bottom of the steering column shroud that it'll go into; it needs to be skinny enough to fit in that hole and the head can't be much larger than a pen head (the core of a cheap pen actually works fairly well for this).

    Then, put the key in RUN and push up on the pin on the bottom of the cylinder. It should be pretty obvious when you get it. Then, simply slide the cylinder out...

    Remind me to get a better (read: bigger) picture of that module; I have one sitting in my wrecked car I can take out and get a good pic of.

    the lights on the key pad light up, and I got the code for it of the module in the trunk, so I am sure it is the right one....the key turns, it starts the car, and turns it off, just stuck in the ignition..bad tumbler or something.

    There are some parts in there that will get the key stuck.
    They are not that hard to change if your good at pulling steering wheels.
    Not actually sure on changing the fords though. i'm going from truck/chevy repair.
    they all work somewhat the same.
    I'm gonna take apart my old column for some testing stuff, I'll give it a look over and post back.

    Thanks for the info in here. It's good to know I can get, or change that code.

    I'm so glad somebody finally posted about this! I kept asking Sam if we could get the code for my car...which he kept saying yeah, it's in the trunk but never told me where. And so I never got it...but now.... Well we'll see if I find it and get it to work.

    Once you get your code. You can open all the doors at once and/or your trunk by pressing a magic number after your code. Also create your own custom code.

    Press 1 after your code to add another code to your car.
    Press 3 after your code to open all the doors.
    Press 5 after your code to open your trunk.

    Thanks to twistedmunkey telling me.

    and, while we're necroposting, I'll throw a freebie in:

    Press 7+9 (at the same time) to lock all doors.
