gilly thanks for good explanation.

yip i was trying to ignore and not face the hard code issue

i want to confirm these codes with the shop again.....i took it off my invoice from them.
if it is the computor i believe that only the dealer can program a new one...is this correct?
so i might have to get the car in to them to program it as last resort.
is it as simple as unplugging the old one , get a new one over the counter and get the service dept. to program the car?

thanks again for your help.
