S2000 Engine Start Button
Simple job, take a starter button from the Honda S2000 and install it in a Honda CRX.
The usual process for this modification involves removing the cigarette lighter or finding a blank area of dash to wire the button into. In my opinion, this would look tacky and actually make the car more awkward to start since you would have to turn the key to 'ignition on', then move your hand to wherever the button is installed.
The only viable solution, as I see it, is to totally do away with the ignition barrel and install the starter button in its location. To whet your appetite, here are a couple of 'after' shots...
The Details
Excuse the quality of those pictures, they were taken in bad light with the cheapest digital camera in the whole world.
Right, if I'm going to remove my ignition barrel I obviously have some electrics to sort out. I toyed with the idea of installing a couple of basic switches to take the functions of 'accessory' and 'ignition' but this would be totally unsecure. Anybody would be able to walk up to the car drive it away! At least, if the alarm and immobiliser were disabled...
Not long ago I installed central locking and wired it to my alarm unit to lock/unlock the car automatically and I knew the alarm had a few spare 'functions' for random duty. So, after some careful planning I decided to wire the ignition directly to the alarm. This means I switch the ignition on and off with a button on my alarm key fob. Since the 'accessory' circuit only powers minor circuits I wired this to a basic illuminated rocker switch which you can see in the image above.
To prevent accidental ignition switching and keep vehicle security at its peak, the remote ignition is configured (via the alarm) to only switch on when the alarm/immobiliser is disarmed. If the circuit becomes powered while the alarm unit is armed the siren will sound and the CRX remains immobilised.
Basically, I now have myself a totally keyless CRX. Walk up to the car, press a button on my key fob and the car beeps. The alarm and immobilisers disable and the doors unlock. Press another key on the fob as I get into the car and the ignition switches on ready for a gentle press of the big red 'ENGINE START' button to fire it up. As I get out of the car, with the engine still purring I close the door behind me and take a few steps before killing the engine via the fob then locking, arming and immobilising the car all in one simple motion.
Appendix
This is a brief wiring diagram of the S2000 starter button with a typical alarm/immobiliser:
The relay shown is a typical 40/50A relay and must be purchased seperately.
Honda part number and price for the starter button can be found in the part numbers section.

Due to germany road law, I cant do away with the ignition alltogether as it will void my insurance. |

Is it possible to add a button like this. and make it so you need to push to button to enable you to start the car with they key? |

You know, this would make a cool show car, especially if you could also start the car with key fob, or will the C/L not support the starter control circuit? Potentially dangerous, I know, but cool nonetheless, hence why it would be best as a show car. |

Not trying to get into or your business or anything but what should I look for in an alarm for my car to operate like yours? I was looking at this (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=60202&item=5777998199) |

Yeah. But weird in a good way :o) And it feels so 'James Bond' to hear the exhaust burble lazily as I kill the engine with my back to the car! |
| MarcusThomas Tue 31st May 2005, 23:24 |
Doesn't it feel weird just leaving a running car though? |

Guess they teach differently in the UK. I was always taught to leave the car in gear and rather avoid using the handbrake too much unless really necessary. |
| hackist Tue 11th Nov 2003, 10:00 |
my instructor taught me to park against the kerb and leave the wheels pointed in such a direction that if the handbrake failed the car would bump against the kerb. i've never parked a car in gear in five years of driving. |
| Kras Tue 11th Nov 2003, 08:00 |
All really nice but only one problem. When you walk out with the engine still on you can't leave the thing in gear which could be quite useful when parking on a steep road (using only the handbrake can be dangerous). Otherwise, an amazing job. |
