Hey guys, got another question. I have a push to start button in my dash already, it works once I turn the key to the run position and then it starts the car. is there a way to completly bypass the key altogether, but not have the car always in the run position, as this would drain the battery pretty quickly. basically I want to be able to dis-arm the alarm, get in the car and push the button to start the car, any suggestions?

regards, The saint

Basically what you need to do is unplug your ignition switch and use relays to open and close the circuits with a toggle switch - one for ignition and one for accessory. You also need to use a relay for crank too, utilizing a push button. Hook up the 12v constant to the 87 and 86 pin on each relay, one for each circuit. Then hook pin 30 up to each circuit in the car. take your toggle switch and push button, ground one side and run the other side to pin 85. This way the relay is handling all the amperage, and the switches aren't overworked. I usually put the toggles in an easy to access location and hide the push button where only you know it's location. Then all you have to do is mechanically remove the ignition switch so the steering column can't lock. Let me know what kind of car and maybe I can throw you some tips on getting the lock cylinder out. let me know

I tell it like it is...

hey, thanks for the reply... So basically what you're saying is that I would have to get in the car, flip a switch to turn on the electrical system, and then hit the start button to start the car correct? is there a way that it can all be handeled by the start button? as I can see myself forgetting to disengage that switch after turning off the engine, and leaving the electrical system on and draining my battery.

Try this "basic remote start diagram" using only 10 normal relays.
Frankly, I don't recommend what you're doing. Ignition cylinders provide safety and security that you'll have a tough time designing...

i know in my friends prelude, he has his car setup for the push button start. he also has 3 toggle switches that control the ignition and all the accessories. All he does when he's done driving and turns off the car is turn off the 3 toggle switches. Seeing as how with a push button start all it does is complete a circuit to the starter. Similiar in sorts to like a valet button on some alarms. Once you let go of the button for the start it's done, no current continues through the switch.

my problem isn't installing the start button, I already have that, what I wanted was a way to have the ACC turn on with the button and stay on, so I wouldn't need any switches to turn on the ACC, and electrical system to the car.

thanks for that... I will take a look at that. I am not worried about someone stealing my car because I have a Clifford RSX 3.5 Alarm /RS system installed, not that it's unbeatable, but I also have no door handles, so there is no lock to jimmy, and no handle to open the door with; so they ! have ! to break a window, wich trips the window sensors, and if I'm for some reason more than 1/4 mile away from the car I get a txt msg to my cell phone that a sensor has gone off. also where I work is right next to the cop shop, and I have a cop on either side of my house, and across the street... (kinda sucks though) I'm not too worried about someone even thinking about breaking into my car. OH, and I will also be installing this : http://www.bypasskit.com/product.aspx?prodid=RFKE-22&catid=6 into my car as well, so without that transmitter the button won't do a thing....

You could do some relay trickery with two stage switch. when the switch hits the first stage it fires relays to get you ign system up and the second stage does the starter. Then wire something up to a door pin so when the pin closes the vehicle shuts down... Off the top of my head, it might work... I wouldn't recomend it though.. I would just use some cool looking toggle switches. I have that set-up in my 56 chev and I don't forget to turn things off.

I have looked over the link hagmanti provided, and it will do the trick, as I have a start button, and a kill switch, so that solves the problem I had.

thanks guys, The Saint

you have to shut the switch off for the ignition to get the engine to shut down when you get where you're going. you could have one toggle control all the relays, this is the easiest way. good luck
