I think my alarm went off and drained my battery. It's recharging now, and has some juice, but none of the key functions work. The manual says that the car may not be operational and to call Mercedes, but they can't help until Monday.

Does anyone know the procedure for resolving this type of problem. I've already locked and unlocked the car with the manual key. Also, my FOB batteries are good.

I think the alarm can corrode and do this. I don't remember where it's located.
