I can do for a limited few either:
Just the remote - Desolder and extend transponder or
you supply the fob with key cut (or cut it later) and I will fit the insides for you.
But I think the extending the transponder option is the safest for you then all you need to do is dremmel the case and drop in the remote... ta da job jobbed
If you want just the transponder doing then pop it in an envelope with your address and a crispy ten pound note and PM me for Address
or
to be fair I will match Gray52's offer below.
P.S. If you want the full monty done then please contact Gray52 first, If he's too busy then I will do it but as I said I'm only going to do this to help out.
