D.I.Y Honda Key Conversion
So I finally finished the last of my Honda conversion. Woohoo. I bought a Honda Accord key and a blank Acura key I had cut and then cut it to fit inside the Accord Key fob...
So here is the new key. It's from a Honda Accord and it's been modified to use my acura key

So first I took it over to ace hardware and had my key cut

Then I took a razor blade and cut open the old key to remove the immobilizer

there it is in the center


now I open the new key fob and pull out the factory immobilizer for the accord

put the RSX one in the accord key

and BAM! Now I have my new key and a blank spare!

now time to program the new fob
Turn the ignition switch ON (II).
Within 1 to 4 sec. , push the transmitter lock or unlock button with the transmitter aimed at the receiver under the audio unit.
Within 1 to 4 sec. , turn the ignition switch OFF.

Confirm you can hear the sound of the door lock actuators. Within 1 to 4 sec., push the transmitter lock or unlock button again.
Within 10 sec. , aim the remaining transmitters (up to two additional ones) whose codes you want to store at the receiver, and press the transmitter lock or unlock buttons. Confirm that you can hear the sound of the door lock actuators after each transmitter code is stored.
Turn the ignition switch OFF, and pull out the key.
Confirm proper operation of the transmitters.
Then also bought this.
bad pictures but you get the idea... the back half of the key fob I ordered finally came in today woohoo! Straight from Japan

Great write-up!
A couple questions,
Did you have to buy another acura key or could you have used the one that you opened to remove the immobilizer? Or did you just buy another one to have a backup key that worked? Also what kind of modifications did you have to make to the key to get it to fit in the fob? And did you just epoxy it in there or what?
I've been wanting to do something like this with my CRX by getting a key fob like you did and the keyless module but I always figured if I mod'd the keyfob the new key wouldn't fit in the fob well or it would be flimsy. Any more info you have would be great.

Good questions I should have answered:
I bought a spare key and had it cut from the hardware store. I cut it apart with a dremel but I apparently forgot to take photos... Just match up to the old key you pull out. And yes I used JB Weld to glue the key in place.
Hey - New to the forum and I've been researching keyfob ideas. The '02 EP3 key does look like this. It's the '03 + that have those wide, laser cut keys. Might this work for an '02? I actually wanted to change the ignition to an '03+ just for the key, but this may be an even cooler, more practical idea.
I'll post a side by side tonight I forgot my phone at home today lol.

The key should work, as long as whomever cuts the key does it properly.
I'd look into a TL-S blank, - though. Looks cooler and is a switchblade. I've had mine over two years now and it's still folding up fine.
And yes, the programming is as annoying as the directions make it look.
