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.
The Details
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.

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.
