Hey got a 2001 Audi a4 Quattro. Batteries in both keys finally went dead. Kept meaning to change them never did. Then when I wanted to the batteries were hard to find. So anyway, during that time, the built in alarm system's blinking red light stopped blinking. Just gone. Now I've got the batteries, two keys, am ready to roll and I can't get anything to happen. I just wanna go back to normal, where I can control the windows, locks, sunroof and alarm all with my master key. Please help.
