just changed batteries in my remote and now it wont lock/unlock doors.. tried to synchronise as per owners hand book but it just wont work....any ideas on what might be wrong..... many thanks

 

Was hoping someone was going to reply to this thread as I have the exact same issue with my c200k and key fob(s).

 

My friend is having the same problem. She has a 2001 C320. The remote will not open or close the doors. Everything else works fine. She changed the battery in both remotes.

Any assistance is appreciated.
