hello all, i just bought a used '97 SC400 a month ago. The guy i bought it from gave me a keyless entry remote that he bought from somewhere(i'm assuming online?) but said it had to be programmed to the car. I've tried some of the programming instructions i found online, but none of them seem to work.....the process comes to a halt after the car locks and unlocks by itself.....anybody out there have program instructions specifically for the '97 SC400???? thanks....
