Dave, here's what happened: Once the fob would not work, I replaced the two small batteries...still would not work..the physical key would not open the door either. Roadside service opened it in 1 minute. Placed the fob/key(with new batteries)...started car immediately.Drove the car home (100 miles). and key opened the door perfectly. However the physical key still would not unlock the door...I thought that if the fob didn't work that the physical key would open the door?????..Thanks... Carl
