Thread: rfid keyless ignition

manual. i went ahead and bypassed the clutch switch so that it doesnt have to be pressed in to start. (i had to do this because i also have remote start installed)

Sounds like your setup is similar to mine with out the push button of course how long did it take you?

maybe 2 hours. it wasnt as difficult as i thought


And that is 2 hours WITHOUT the steering lock removal.

your setup seems to work so good. ive been looking for something like this for a while. do you mind revealing all the parts you used and how you hooked it up? id really like this for my car.

Do remember that you will need to figure out how to remove the steering wheel lock on your car. The key on 99% of cars engages a mechanical lock to the steering wheel, which makes it impossible to steer the car without the key in. Not impossible, but not just a few wires.

i know, ive been in the steering column in my car quite a bit and the mechanism is simple to remove.

My push button start works like this...
1 second after push, ACC/IGN is powered up...keep holding 1 second longer and the starter engages...
If you just want ACC, let go after 1 second.
To turn the car off, push the button again. It also has a powered output to use with an ignition/antitheft bypass unit, if you want to go completely keyless...

the main components are

2 - dei 611t relays(ebay $20/each)
1 - set of relays (like the ones that come with a remote start system or one relay for acc, one for ign1 and so on)
1 - ordinary (momentary) push button.

Basically the dei relays can be used as either latched relay or timed relay(0-100 seconds) and they are activated by either - or + pulse.(from the push button) i used one as latched and one as timed. They are both activated by the push button. the timed output can be adjusted for a suitable crank time for your vehicle. You will want to have the output going to a relay, not directly to the start wire. the other dei relay is set to turn on a set of relays that keep constant power to acc. ign1 ign2....etc so it will turn the acc ign on and send a timed pulse to the starter all with a push of a button. ****one thing you will want to do is put a NC relay in line of the pulse activation wire that runs from the button to the timed ouput relay. It should open(break) the contacts when its recieving a + signal from the latched relay. (this is very important it prevents the starter from engaging when you push the button to shutdown the engine.

Ive been looking into doing this for my scion and was wondering if you could help me out with a quick how-to
