Ok, so there are two 97 Lincoln Town Cars in my driveway and I have to admit I've fallen in love with the keyless entry keypad above the door handle. I had to replace one of the keypads and a window regulator, and while I had the door apart I realized how easy it would be to swap this system into another vehicle.
I have an aftermarket immobilizer in my 94 GT and I plan on wiring the keyless entry into it. So far I have a spare module for it that goes into the driver door and a keypad with a bad button(no big deal they are $10). I will need to find a very specific wiring diagram for the keyless entry system(not to mention the Toyota), and the door wiring harness from a Lincoln towncar.





Spare Keypad, 1-2 button doesnt work but I can get them at the salvage yard for $10




Driver door Keyless Entry Module, stores 5 codes. cost $35 at the junkyard.





So so far my total starting out for this project is $35, Ill make sure to keep you posted.
Lemme know what you think!!!

Ok, so I've had a breakthrough in my brainstorming, rather than install an ugly keypad on the door, I will paint the circuit into the driver window with conductive paint. I got the idea looking at this- http://www.bareconductive.com/555-touch-circuit

I would have 5 buttons on the window sprayed with some kind of conductive paint, nearly invisible. I could backlight the glass or add UV/Flourescent paint to the conductive traces so LEDs could light them up from inside the door. I'd use 555 or 556 chips in monostable mode similar to the website's circuit to make all 5 conductive traces act like the Ford keypad's buttons did.
My only real hurdle is to find a conductive paint that is durable enough to survive the elements and having the window rolled up or down. Im considering the idea of putting it on the back window because it wont roll down and rub the traces off. Also will water cause false positives? I need to build a test circuit and start experimenting!


Things I have-
Keyless entry control module
Keypad with broken button
Spare celica door harness.

Things I need-
Conductive paint, waterproof
Build control board for window keypad
Lincoln door harness




Let me know what you think!
