Hello, I have a big problem with Central lock on my Mercedes! I have to manually unlock the doors, no sound coming from the pump. The Unlock button in the center console does not work at all! I verified all the fuses in front and rear, they are in perfect condition! I could know what to do ..... My car is a 1994 C280 and I do not have the remote .... Can someone help me?

 

I had same problem,had bad pump.you didn't. Say what happened to remote.was it working fine w/o remote.did you open manually w/key drivers door.or lock/unlock from trunk lock.you need another remote.
