How to fix central locking system that wont work properly
Hi, so my car, a Mercedes-Benz C220 W203 from 2004 is doing a thing where it won't unlock or lock remotely from the key fob. I went to a guy who said it could be the SAM but I changed it and still won't do its thing. It happened to work once or twice when i was clicking my key multiple times and somehow it worked then the day after stopped working. I also changed the battery. Any help, advice or answer is welcomed.
