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

did you get the hatch release button to work.
?

that would be a veryy nice addition =D

Re: D.I.Y Honda Key Conversion
 

No because the RSX doesn't have a remote button pop it has old school cable pull hatch.

They make a key without the trunk but it was more money :P

Re: D.I.Y Honda Key Conversion
 

This should technically work with an ep3 correct? Since I'm buying extra keys anyways...

Re: D.I.Y Honda Key Conversion
 

not for my 03, the blank is completely different....

Re: D.I.Y Honda Key Conversion
 

crap on a cracker...

Re: D.I.Y Honda Key Conversion
 

damn thats cool. how much did this all cost you about?

Re: D.I.Y Honda Key Conversion
 

its not as costly as time consuming

Re: D.I.Y Honda Key Conversion
 

to bad it won't work on the EP!

Good write up btw :thumbup:

Re: D.I.Y Honda Key Conversion
 

sorry for sounding stupid for asking this but what makes an ep's key so different that this wont' work for it?

Re: D.I.Y Honda Key Conversion
 

ep key has no groves, Its designed for a different kind of lock.

Re: D.I.Y Honda Key Conversion
 

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.

Re: D.I.Y Honda Key Conversion
 

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.

Re: D.I.Y Honda Key Conversion
 

I want to do this with my 99 Accord but I cannot find a key like this one with that blade that you have. Where did you get that? And how much was it?

Re: D.I.Y Honda Key Conversion
 

do you have a part number for the accord key? .or know what years i should be looking for?

Re: D.I.Y Honda Key Conversion
 

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.

Re: D.I.Y Honda Key Conversion
 

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.

Re: D.I.Y Honda Key Conversion
 

Do you guys know of any practical way to switch over to an '03 + key at the same time? I know I would need the ignition, door/trunk locks, immobilizer.. anything else I'm missing? I spoke to one person on Kijiji who was parting out an '04 ep3 he crashed, and now has an '02. He switched all the keys / locks over but said he lost his 'Anti-theft'.. I wasn't sure what that meant and I couldn't get a better description but that would be quite important to me to retain the immobilizer & 'Anti-theft' if they are the same thing even..
