Don't get caught out with the batteries running outin your key fob without warning as it happened to me yesterday. I have a 9000 Aero and I locked the car with the remote and I was unable to to unlock it with the remoteas the batteries were dead. I phoned Saab at Turners hill who said that the car would not start without the fob working. Only 40 miles from home and the spare fob!. So a 10 minute walk to the nearest Ford garageand minus £8.95 for two batteries the car started.Glad it wasnt midnightso learn from my misfortuneand carry a spare set of batteries in the car.Just ordered a spare setfrom Saab£6.54.
