I wonder if it's possible to replace the crystal to match the Mhz?

 

someone had to ruin your dream sooner or later, if it wasnt him it woulda been me. i been following these kinds of topics for a while coz i want one of these keys. i even went to some people that cut automotive keys and asked them to do it for me, they said that it wouldnt work.

 

here's a thought, replace the key AND the reciever in the car. while your at it, figure out a way to rig the windows to open up on command of the key. just like the accord.

 

Actually the fob for MY03 transmits at 307.9000MHz. I still don't think it will work though. I looked in an old TSB that covers the remote transmitters.
From another thread:
If you really want to know the frequencies look at the back of the remote for the FCC ID. Use this number and check it against the FCC's online database. The FCC has the frequencies on file.

EDIT: I did remote for an 03, heres what I got:
Applicant Name=Omron Corporation

Zip Code=600-8530

Application Purpose=Original Equipment

once youv'e searched click on the icon that say's "view form" for even more detailed info.

 

My FCCID is exactly the same on an 06 remote.

The seller of the Accord key posted the FCC ID, OUCG8D-380H-A. It shows up as
Lower Frequency In MHz: 313.8
Upper Frequency In MHz: 313.9

Ohh well, I get to keep my weight reduction if I ever need to remove the remote.
