Question about Cars & Trucks
Someone changed my ignition to my 2002 for Taurus 4 door - and didn't realize it has a security key code. I paid to have a A-1 mobile service come out to try and reset the key however it didn't read the new key. The " Idiot " who replaced my Ignition may have messed up the antenna ring that goes around the key ignition which typically reads and syncs the keys to start up the car. However back to the "Idiot" who was working on my car also pulled out a 1/2"x1/2" square circuit board thingy that apparently has nothing to do with the ignition switch and I was wondering if anybody knew what the purpose of that chip is and/or if it could potentially have anything to do with my car not starting up? Its located on the right side of the steering wheel in the dash next to the lower part of the stock stereo , almost underneath the dash next to the ashtray. Now I had no idea "idiot" was even going to touch my car because I didn't need it worked on. I had misplaced my car key and just hadn't gotten around to picking up my spare key from my place because I had been ill with the flu. "Idiot" wanted to surprise me and unfortunately took it upon himself to swap out my ignition leaving the ignition he pulled out in a condition unable to be re-installed. Needless to say my car ran perfectly before that but hasn't started since. Upon trying to find out exactly what "idiot" has done to my car, I have decided to watch every u tube video in regards. I even made an attempt on a different page and asked the community(similar to this page) but I know so much more now about my car and the parts so I can only imagine how dumb I must have sounded so "NO WONDER" as to the NO REPLIES" to my question than. However in the process of trying to figure out what the problem could be here - I have learned how to remove and install my heater core(however everyone on the ''Show You How You Tube Vids" literally dismantle there dash by cutting & removing a chunk of there dash in order to get to the heater core and I thought -WTF! there has got to be a different way to get that bad boy- like lifting the car and going from the underneath to the firewall and so on... maybe???)I also learned how to replace my intake manifold thingy and what the 'O''(oh) Rings replace the and remove and replace the gaskets from the "O" (oh) Rings and how to remove the fuel line and the fuel adapters and replace them all, where the automatic fuel switch is located and that it shuts the access to fuel pump incase you get into an accident or bump something like a curb and if your car doesn't start it could be that the fuel switch automatically switch off so go in behind the drivers side of the trunk and look beneath your stock stereo speaker deck and you will locate the automatic fuel switch. You can bypass this switch by simply pulling the cords and switch toward you and locating the two red wires attached to the switch and cutting the switch off the two red wires its attached too-but it was installed by the factory to benefit the patrons should we get into a car accident so don't do it just because you might hit a bump to hard. However mine shut off from being towed from my old place to my knew thanks to 'Idiot". A really BIG- FYI- to the public is please note that I have not tried to bypass or do any of the above descriptions that I have learned in my quest to fix my car but I did watch the Vids and I did take notes and I did learn something new with just about every video I watched and "I HAD NO IDEA" However there is a purpose to my madness here and so the reason behind me sharing what I learned is in hopes to -SAVE YOU TIME-HELP YOU TROUBLESHOOT-HOPEFULLY HELP YOU FIX YOUR PROB -but mostly- TO GIVE BACK TO THE COMMUNITY IN HOPES SOMEONE WILL TAKE THE TIME AND REPLY TO MY CONFUSION BY SHARING THEIR PERSONAL KNOWLEDGE IN HOPES I CAN GET MY CAR BACK ON THE ROAD. Thanks. D
Sure. I will try to help. The car won't start because the factory installed security feature will immobilize key components of the ignition or fuel or both systems to prevent theft. Best thing you could do is have the ford boys check that antenna ring thing, and get the system up and running. You asked for a diagram of everything under the dash. Believe me, you don't want to go there, even if such a diagram existed. Too much extraneous! What would help you is a wiring diagram from a repair manual for your Taurus. Then you could identify by the color of the wires what that circuit board piece is. It may be part of the security controls, may be the main module, or it may be something entirely different. If you can disconnect it easily, you could take it to the parts place at a ford dealership to identify it from a part number. Or if can locate a part number, write it down and take it to them.
Keep researching for what you need. Looks like your choices are pay ford's outrageous repair prices, or keep trying to fix it yourself (then do buy the repair manual for the wiring diagrams, and for the recommended procedure to replace the heater core), or find the site where some have published how to disable the alarm or security systems. Just google it, there are some sites. Good luck.

sound like the tumbler is falling out, when you open the steering column there should be a hole where a small but solid object can go in.. this release the tumbler but only when the key it turn at a certain position you will feel the pin in the hole go inwards then you can slide it out...it could be defective or just need to place back properly..hope this help..

Check out the vwfixx.com forum online. One guy has a step by step procedure on removing the ignition, says it takes about a half an hour.
