k i bought one of these keypads mentioned above, wow, where do I start. How about with "DONT DO IT!!!!" after four or five starts, the key to number 1 cracked. Luckily i had a valet switch installed and could get my car back to the shop to have it removed. Good stuff. I was very pleased.

seriously, why would anyone want to do this? For "security" purpose?

those things are the worst, would take a theif about 5 seconds to bypass.

Well if you did it right and hid the wires properly, flush mount it into the dash or something and hide the relay or what not you could prevent the thief from taking the car. Of course if he thinks he has time and tracks down the wires and stuff he could still bypass it. Or just get ****ed and wreck the car.

Okay now I've been having this code lock idea myself for some time. I even found a single chip solution for it. In the first place I thought it would be cool to have for my PC.. but in the end i got a PC case with a lockable front (no power button accessible) so it baceme obsolete. Now I read it here and I thought maybe some of you migh like to have the information about it. I'll have a look for the single chip solution. In the meanwhile I'll post some links of some schematics to make them yourself.

http://www.electronic-circuits-diagr...rdenckt2.shtml <-- this one can be made to use an 8 digit code with rotary wheels. Might also be possible to do this with some keypad matrix tho.

I'll have a look at my collection of PDF files to see if I can find the IC I found a couple of years ago.

[EDIT]

This was the IC I was talking about. I hope someone kan make some use of it.
