The Real Push Button Start
I been seeing a few threads go up about push buttin start. BUT all of them include putting the key in and turning before u hit the start button. So i though i would share with you guys a real deal keyless entry and push button start system that some guy over on SF makes. I know most of you dont visit that site and to see this thread you gotta be a member. So here is his youtube vid and some pics

AND super old.
he started this in 2008 and last time i checked, he hasn't ever finished it yet (although he keeps saying soon, alot of people are hopeful). plus he's building it for the supra so i dont even know if it would transition to the sc 3/4
lol i used to follow this thread along time ago
dont get me wrong OP its uber cool and since i no longer have my sc i wish they had one for the gs but these are really model specific units.

i don't think its really specific to the supra. looks like the button is from a newer lexus, like an is350 or something.
I wonder if the button and key just work together or do they communicate with some ecu on the car. if you could do that and get the doors to unlock when you walk up that would be something!!

There are a few members on SF that have bought his kit and have had no problems with it thus fare. I mean it not as perfect as the smart key on the newer Lex models but its really close. He is making another bach of better units and should be done with them "soon". So we'll see and no it not specific to the supra, read up on the thread I thought i'd post this show that a "real" push button system can be done

POLL OPTIONS:
Trying to make up my mind:
(A) Keyfob w/hidden key + smart start button = You get a Keyfob with a hidden blank key. Fob communicates to box in car. Once your 2-3 feet from the car, it automatically locks/unlocks the doors and enables the start button. It also allows anti-carjacking. If the fob is not in the car within 30 seconds of you starting it OR opening then closing the door, cuts the ignition via the start button.
(B) Smart start button ONLY = Just the button and circuitry. It will need a signal from another alarm to enable itself and let you start your car. You would use your alarm to lock/unlock the doors. This is the best option for those of us who have a nice COMPUSTAR alarm system with the 2-way pager. The hidden keyfob is nice, but you'll end up carrying to large fobs everywhere you go.
(C) Automatic lock/unlock as you approach the car = Best convenience if you choose the keyfob option, but may become annoying if your working on your car. You can cover the keyfob in aluminum wrap, turn off the RFID via a button, or keep the key near the car.
(D) Must touch car to lock/unlock = Small hidden sensor near glass. Keyfob enables this sensor. You touch sensor to lock/unlock the doors. Issue here is you *can* leave the fob in the car and it can still lock on you.
Integrated Key Fob with internal Supra Key and smart keyless circuitry - Custom cut supra key inserted into keyfob. OEM Infinit fob guts tossed in favor or custom circuitry. Only one button works for emergency lock/unlock.
Prototype unit - fairly complete minus the button.
Circuit progress

I'm almost done working on a product and am looking for any interested parties.
First off, these things generally cost $2000-$3000 if you buy all the parts seperately. I can probably get this down to a few hundred dollars.
What: Auto push button start with auto-detect keyfob. Key the fob in your pocket. Get close to your car, open your doors w/o a key. Get into your car, push the button, car starts. Key only needed for opening the door manually.
Included:
RFID fob - 128bit encryption, new code generated each time you walk away from the car. I haven't yet decided how to incorporate the Supra key inside (like most do). I may request you ship me a copy of your key so that I can create the key-in-fob desgn or supply a kit that allows you to cut your key and slip it in.. or send me a remote that you use (alarm remote) where I can insert the frequency detection guts inside for a clean design.
Smart Push button - You push once, turns on accessories. Push again, turns them off. Anytime you put your foot on the brake and push the button, it cranks. Stops cranking after the tach signal reaches idle. Push again, turns off. The button will only function if the fob is in your car. I have yet to develop a column-lock solenoid if it can even be made. I may have to look at late-model toyotas to see if there is anything already available. If not, I can still offer this unit with the intention that the user resolves column-lock themselves.
Theft concern: It will be component based. If your a thief and you know the supra wiring, a few cuts and twists you can start the car. I plan to include a seperate connection for the fuel pump. You can always use this system with your current alarm, so there is that option.
I am looking at a few weeks for a test mule to be completed. As with anything, I would not be responsible for car theft, just like a turbo supplier isn't responsible for you dying due to excessive HP.
