I know I've only been a member for a few days, and I apologize for being intrusive...but, as with all Omega owners, I have a problem...(I think it may be mental)

I've had three of these things...
OK, this is it...Let's see if I can categorize it...C/Locking is a bit dodgy but that'll be mainly down to servos or limit switches...Usual thing, passenger door won't lock or unlock with remote, or key in the driver's door, (have to do it manually) but that'll be the servo or wiring, I'll repair that...(done it before)...I was an Electronic Installation Technician, in a former life...For my Sins...(It's amazing how many people want PCs building or repairing. For nowt, of course)...But I digress...
All the doors, (except f/passenger) would lock with the key in the lock, set alarm and deadlock...
The back doors would lock and unlock with the remote and pop up again 'cos driver's wouldn't lock (not driver's or f/passenger, though...Servo/limit switch, Again) Remote would set alarm and deadlock, after locking with key in door......That's no problem, I just locked and unlocked with the key...And reset alarm once inside...Remote would close windows and S/Roof, so, OK there...
Then the fob stopped working....So, I took it apart, some one had repaired the battery holder with bridging wires but one had detached...so I resoldered it, properly ( I've done that before, as well)...New battery...fob working fine...But (and there's always a But)...now the c/locking steadfastly refuses to respond...at all...and Yes, I've tried re-syncing it......Nuthin'...
So, this is the main question, I can get my hand on a replacement fob, however, the question is...Is it a simply a matter of transferring the original blade and transponder to the new fob or am I going to have to get the whole nine yards reprogrammed. Because even though it appears to be working, (Led operating) I think that the original fob PCB could well be fried...

The key is still locking and unlocking the car and is OK in the ignition...But it would be nice to have remote C/Locking that actually worked...especially as I have only the one key...
Oh, and incidentally, the power sounder doesn't operate, just the indicators flashing...I think that this may have been an on going problem and that's why it's been rendered inoperable...Or there may, simply, not be one, I haven't had a look yet...
I've only had this Omega a coupla' weeks...Ongoing Project...new Ex/Manifold, tomorrow...Its blowing...

So, if I can pick your brains and if there's any one out there with advice on the fob, It would be appreciated...Perhaps Mr. Imber may have some input, here...
I've trawled the forum and my apologies if it's been covered before....but there doesn't appear to be be a problem, quite as complicated as this...
Car 2003 2.2 CDX Estate...Two button fob...If that helps...I live under no illusions... It's gonna cost me, what ever it is
