Its all good now, I didnt go to reno, in the end I fixed the key myself.  What had happened is a little button type switch thing that makes the clicking niose when you press the key to open your car, had came away from the chip. I thought something was wrong as there was a rattle inside the key????!!
Thats why there was no click when I tried pressing the button.  Anyway after getting the chip out of the half side of the key, i decided to super glue the button to the chip, becuase I havent got a solderer.  it was ok I didnt superglue the connections just the plastic part of the button in the middle and made sure both connections where touching on the chip!
And its works yeppee, saved me a few quid, PROPER BO!
