Having problems with your Mercedes-Benz C-Class ?

Hi, My cars central locking (C220 model) has stopped working all of a sudden. The doors will not lock/unlcok using the key & i am using the key (metal) bit to open and close the doors manually. When i press the lock/unlock button on the key, red light flashes, so battery is fine i think. Can someone please help/advise what might have happened and whats needed to be done to resolve the situation. Really appreciate your help. Thank you. SS

Replace Fuse 27 in main fuse box located under the hood black box in far right corner. Then try reseting your battery. Make sure to follow these steps as follow. Unhook the - then + of the battery. Clean both the negative and postive of the battery. Next go under the hood far right and replace Fuse 27 which is 15 type fuse green in color. Wait 20 minutes for reset of the computer then attach the + and - cables back to the battery.
