About four months ago, our 2000 S80 started giving us problems. It wouldn't start every time. You could put the key in the iginition, turn it, all the lights would come on, the fans would start blowing, the radio would come on, the fuel pump would whine, but the motor wouldn't turn over. It took three weeks for our local mechanic to duplicate the same problem. AFter consulting with two other dealerships, he finally concluded it was a problem with the security chip in the ignition key. He got the keys "re-programmed" and everything seemed to be OK. Until last night. It started doing this again. We had to leave the car overnight in a shopping center. We got back to the car this morning, and the damn thing started right up.

Has anyone else experienced this problem?
