The remote fob has been working sporadically for the past 6 months but if it decides it doesn't want to work I have always been able to use the key to open the doors and disarm the alarm. Well today the key trick didn't work. It unlocked the door but didn't disarm the alarm so when I opened the door the alarm went off. When I tried to use the fob to shut off the alarm you could just hear a slight buzz inside the door panel. The fob would lock the doors but not unlock them or shut off the alarm. I finally had to pull the fuse which killed the alarm but also disabled my power locks. Any suggestions?
