Hi guys...my sister-in-law drives a 1997 C230 and apparently neither remote clickers (with brand new batteries installed) lock/unlock doors. She would use the mechanical key for now. Any suggestions? Blown fuse somewhere?

Thanks.

 

Probably needs to be re-synch'd. Procedure is in the owner's manual. Should be something like turn key to position #2, hit 'lock' on fob, turn back to position #0. Should then work.

 

did this solution work for you? My clicker is not working either.
