2003-2007 accord key retrofit
The accord key has the key and the key fob on the same unit. Currently this is not possible to use on the s2k because the s2k keyless entry control module(KECM)has a 307.9 mhz receiver (FCCID E4EG8DJ). This is however, possible on the RSX(here) because it has a 313mhz receiver(FCC ID OUCG8D-355-A).
If I can get this to work, it would then be possible to use the RDX/TL switchblade key also, as seen here.
There are a couple of problems to this, the USDM has an 18pin connector, while the UKDM and JDM have a 14 pin connector. I cannot find a full Wiring diagram for the USDM KECM anywhere, just the wiring diagrams for alarms and such. I did find one for the euro-spec connector in this thread. Another problem is the immobilizer, I don't have to worry about this since Kpro disables the immobilizer. If it is anything like the RSX, you should be able to pry open the key, and swap the immobilizer to the new key.
I have a couple of theoretical solutions to this. One is to get a UKDM KECM with pigtails and use the wiring diagrams of both to wire it in. Another is to see if the antennas in the KECM are the same, and solder it out and into the USDM unit.
If anyone has a full pinout of the USDM, UKDM, and JDM Keyless Entry Control Module, I would sincerely appreciate it.
I know it doesn't seem worth it for the amount of work and money I'm putting into it, but I think this would a pretty cool upgrade and very OEM looking. I hope someone with more electrical knowledge could help me out.

Ok, now all I have to do is get a hold of a keyless entry control unit. I should be getting a JDM unit soon. The wiring doesn't look too different, hope I can get this to work. If there is someone with more electrical knowledge and can assist me further, that would be great.

New revelation. It seems that the JDM s2k keyless entry control unit has a 313.85 MHz frequency. It looks like I'll have to find an UKDM module. This might take a bit longer to find.
