Not too sure if this has happened to anyone before, but today when I got to my car to drive home from work I am unable to open the car. At first i thought its probably the battery in the key fob so i went and bought a new battery. I am still unable to get into the car. The key also doesnt do anything when i manually try and open the car. I've never experienced this before. Luckily I had access to another car so as I could get home however I am wondering what my next steps should be. sign up for the AA and hope they can get in and figure out if its the car battery or at least tow it home.. Has anyone had this happen to them before? I dont really want to have to break the window.. Its an 04 A3.
