Hey -- thanks a bunch for the help again. I did not have a chance to check the fuses one by one this weekend. What I did see was that the battery was consistently above 12V so looked ok... but the car was still acting funny: locking/unlocking with the clicker was finicky, and at one point even locking/unlocking with the button in the door didn't work, but sometimes it was fine. Then this morning... the alarm went off again, randomly. May be more sensitive in cold weather since it is quite a bit colder out today than it has been.

Anyway, I am going to take it to a shop to get looked at since I don't have the time to do it myself. Any recommendations on whether I'm better off going to a dealer or a chain shop like Midas, VIP, Pepboys...?
