Keyless ignition

Hi,
    I noticed that there was a couple of forums that had people touch on doing a keyless ignition push button system, but none with detailed information.   I was hoping that to help everyone who is interested in doing this that one or some of you on this website can give detailed information on this.

    Here is the scenario, I have a 97 Honda Civic EX with a Viper 5706v car alarm that is a 2way and remote start. My ignition has been damaged by a thief and i cannot replace the ignition since the steering column was damaged. Therefore, I want to be able to start my car with a push button/switch without us of any keys. The button must engage all 3 steps of the ignition process, Acc 1, Acc 2, and momentary start.

Thank you in advance everyone. Please use as much images and videos as possible.

You will want to do it properly.

Thank you for that link, but I want this system to work without a RFID device and without buying a kit. I want to do this from "scratch".

WHITE/ blue at H2 on the Viper, momentary switch to ground.
Extremely unsafe, make sure you're in neutral if the vehicle is a manual.

This is a subject for debate. In my opinion you can always buy a tumbler with the key. Since its a 97 there is no immobilizer. Next to nothing for a tumbler from the scrap yard, and have the dealership cut you new keys. If the steering column really is damaged as you say "can't replace" how are you able to drive it then?

imo do it properly or don't do it at all.

Howies suggestion would work but very unsafe As he mentioned. Not really what you're looking for since that will only activate the remote start, shutdown after programmed run time and shutdown upon brake input

Thanks for the comment Ted, I suppose you could have an SP switch for the ignition and another for the ACC but seriously cheaper to replace column and tumbler, also much safer.
BTW Ted, the other show is Monday Mornings from Fox, just started here, rather like it.
PS you can buy a multi way ignition switch, OFF/ACC/IGN/Start from an number of suppliers over here.
Ignore the steering lock, mount it anywhere convenient.

Thank you for your input guys, but please don't use my post as a message forum to each other, put information that is "safe" and answer the question without negative feedback. I just want safe and possible answers nothing else, this is why this question is never clearly answered.

   Here is a video link showing someone successfully doing this: https://www.youtube.com/watch?v=_JRSkToc1Yg. Yes I tried contacting him with no success.

Browse the relay diagram section. Use your imagination. If you know basic relay circuits, you will come up with something. I did. It would have about 10 relays and some diodes in it, but it would do what you want.

Hint: This is the foundation. You have to add some stuff to it, but it can be done. If your Honda is a stick, incorporate the clutch pedal switch for safety.

Nice answer Dave, I'd guess KP technologies is also worth looking at.

No chip required if no OEM immobiliser fitted.

That's a $179 solution. A junk-yard steering column should cost less than that.

I get 15-20 mini-relays for the cost of my $2 admission to pick-a-part. I pull relays out of under hood boxes and toss them in the bottom of my tool tote.

I've used my imagination while browsing the relay diagrams and come up with some cool solutions and devices for various "what-if's". I've built and installed a few in my cars and trucks. I get a rewarding feeling every time I use the device. It's something I came up with, built, installed, and it works. For virtually zero-cost.

The OP would get the same satisfaction from designing, building, and installing his own device every time he starts his car. I encourage him to do so.

But design in some safety features. Like foot on the brake or clutch to activate. Door-open kills the "Accy" feature. Etc. Be safe.

Thank you davep finally someone who is ok with giving me info. to do what i'm asking. Not convincing me to not do it. I am an extreme DIYer I push to try to do everything until I'm physically unable or financially unable to.

You have to design your own system. If you don't have a solid basic understanding of relay-logic circuits, you may not be able to design it, and this project is therefor "too much" for your current skill-set. No biggie, we all had to learn what we know from somewhere. Keep studying the diagrams, build some circuits, experiment. Teach yourself what you need to know. Get your system to work on the bench, then go for it live by installing it in the car.


I just did a 5 minute block sketch of the elements to what is needed for this device. I came up with 17 !!! relays to incorporate the features I would want in the system, (I guessed at the need for 6 relays for 2 ACCY, 2 IGN, and 2 Starter). (I don't know Honda's, so I'm not sure, and I didn't look up the wiring). Wow. While I have the capability and knowledge to design and draw this device out for you, I'm not going to. Here's why:

Certainly for liability, but mostly to avoid the frustration of attempting to do a system this complex over the internet. We had a guy on here awhile back that kept blowing fuses on his simple, everyone understands it, 5-wire lock system. It went on for weeks and 6+ pages. FINALLY, IIRC it was Ween or IAAI suggested that one of the relays was a different type than the normal SPDT that we all assumed it was that was causing the blown fuses. Someone finally thought of something new (which was "it"), but it took weeks and was frustrating for everyone. I learn from these episodes; I'm not going to expose myself to that kind of frustration. Sorry.

Here's some ideas for design features:

You have to design and incorporate your security features.
You have to identify and test the wires in your car for what has to be powered for start, run, and accy.
You have to design into the system, then interface into the car, your safety features.
You have to think about, design in, then install an over-ride feature in the event that the device fails at an in-opportune time for troubleshooting, like alongside a busy highway.

The relay array below is the foundation. The START/STOP button activates this array.
Each push of the button changes the state of the "12 Volt Output" (blue) from off to on, and back. Use this output for RUN relays.
#86 on the far left relay remains (-) as long as the button is depressed during the ON event, so use this trigger for START relays.
#86 on the far right relay is (-) trigger for STOP. Use this trigger to turn off the ACCY / ACTIVATE array. (Discussed below the image).
Don't connect the red "constant fused 12V" to a constant source. Use your security features and the brake pedal to activate a latched-on array to power the foundation. The output of this latch is also the ACCY function.



Browse the relay diagrams. There are several ways to do a latch-on array to power the foundation array (the red fused constant 12V hot), and the ACCY relays. Use your alarm aux output, and the brake switch (+) to energize this array for security and safety. Then use the (-) STOP output from the foundation array to turn off the AUX/ activate array.

Good luck. Study hard, patience, and you'll get it.

Wow, thanks for your time and info. i definitely will start researching. i have pretty much a 100% understanding of my car electrical, now i just need to incorporate this "over ride" SYSTEM.

Quite right Davep it was IAAI and that Honda has 1 X start, 1 X Ign. and 2 X ACC.
