HELP Please! Key Fob not working/ alarm won't disarm
1998 E320 Wagon:
Key fob not working, can't disarm alarm, wipers, window controls & central locking won't work....suggestions?
In the middle of a crazy NW winter snowstorm my key fob suddenly stopped working! Took the kids sledding, worked fine when I locked the car, but 45 minutes later when we went to leave the doors wouldn't unlock with the fob. Used the mechanical key to open drivers door, which set off the alarm. Fob wouldn't work to disarm, neither did putting electronic key in ignition. Car starts...drove home with window down, alarm blaring and lights flashing. Once engine is off, it goes through 2 alarm cycles, then turns off unless I open a door.
Help please! Husband is out of town and I can't even get the car to a mechanic to check it out due to snow!
I have tried:
new batteries in Fob
re-synching fob according to directions found here
key in ignition and resetting central locking
disconnected neg battery connection for 15+ minutes
checked for blown fuses (and was able to pull the horn so at least it wasn't honking while I tried to trouble shoot!)
Does anybody have suggestions of what else to try? Is there a reset code (we have an aftermarket radio)? Is the alarm connected to wipers, windows not working?
