2002 C230 Kompressor Coupe: Key Remote Lock/Unlock Not Working, Key Won't Turn
Ok, here are the details: last Sunday, I left my key in the ignition overnight, possibly in position #2 after shutting the engine off. This drained the battery by morning. So, I began a trickle charge and got new batteries for the key.
Once the battery was recharged, headlights worked, radio worked, lock/unlock dash control worked, dash info. lit up.
The key is recognized when put in the ignition (buzzing sound, steering unlocks), but the key does not turn.
Also, the remote lock/unlock function is not working.
I'm hoping there is a simple way to re-synchronize? The car was working fine before this happened. I'm not mechanically inclined, but it appears that the security system is not back on, either.
Should all automatically reset, or since the key was in the ignition when the battery drew down, maybe there are steps to re-sync?
I've found similar posts/issues, but none specific to my situation.
Any help would be appreciated.
