so ive been building my car sense 2006.. somewhere along the line i lost my key... i can either get a new ignition re-key.. or just go with engine start button...?

any downside's to the engine start button?

car is not a daily at all when i take it out it wont be out of my sight

 

if you're going to be rekeying it anyway, might as well go with the push start. i cant imagine the costs would be very different..

i vote push button.

 

correct me if im wrong but on the push button start dont you have to have the key on the on position to start it with the button? if thats the case you gotta rekey it anyways

 

i was thinking about just putting a switch ... it would just like the key begin in the first click position activating the electrical and whatnot.. then the S2K start button to start the engine... sounds legit in theory

and i guess just turn the switch off to turn the car off

 

You still need the key so the steering coloum does not lock while driving. Unless your going to break the key cylinder off. Even the s2k has a key. You can not start the car without it. Its not that hard to add push button start. A push button and a single relay and your set

 

You have to take the key cylinder off the column to remove the steering wheel lock.

Your start button will have to accomplish several things. First, it has to power up the ignition circuit. Then it has to crank the starter until the engine starts (assuming it's a push and let go setup like the OEM's), and then it has to stop cranking (when it gets AC signal on the blue tach wire at the distributor or from the injectors). Once the engine is running, the button has to maintain power to the ignition circuit, and then it needs to give power to the ignition 2 circuit and accessory circuit. And finally, if you push the button again, it needs to cut power to all the circuits that it's powering. You can accomplish this with a bank of relays and a lot of patience and thought.

The easiest and most common way is to have 3 high current switches for Accessory and both Ignition circuits and then a normally open push button for the starter wire. You cut all these wires from the key cylinder that is removed from the steering column.

Actually I'm pretty sure there's an immobilizer too.

 

starting to sounds complicated...

i already disabled my steering lock... all you have to do is drill a hole in the brass colored circle plug on the bottom of the ignition.. and the spring will pop right out... and walla .. no more steering lock
