Recently purchased a 2007 MS6. Had some issues but I’ve fixed just about everything. The key fob wouldn’t lock or unlock when I bought it. I replaced the battery in the fob and it worked immediately. Then the next day it doesn’t lock again. I leave my keys in my car. Can this run the battery down in the fob? Also another issue that just popped up randomly is the master window switch will only roll the drivers window down. While the other switches roll there respective windows down. I’m going to mess around with the fuses and see if anything is blown. Going to college in 2 weeks so I need to be able to lock this sucker up. I want to add that it makes a beeping noise when I get out of the car. I also leave the plastic cap thingy in the car.
