97 E420 remote door lock issue
 

Hey guys. Any idea why my remote door locks sometimes wont work at all? It seems to be an intermittent problem. I will try to unlock it, and it wont, no lights flash. I am forced to unlock it by the key. As soon as I unlock it with the key, the remote works again.

Any ideas? Its driving me nuts!

UPDATE
 

Update: its fixed.

On my lunch break today, I went out and unhooked the sensor in the drivers door handle. Immedietely the system started working again. The rear-view mirror sensor and the trunk sensor work just as they should, and the range has increased as well. That sensor will stay disconnected, seeing as the dealer wants $450 for a new one! :eek:
