My battery in my A4 died. I replaced the battery and found my keyless entery doesn't work anymore now. Would I need to reprogram the remote? that is a bad design if so. But if I need to reprogram it, how do I do this?

Also, I've tried to reset the windows auto up/down following the instructions in the owners manual. but it doesn't seem to work either. Is there a trick to that? Does the car have to be running, or not running, or in the acc position?

I've had the car for 4 days so this is all new to me, sorry if its all noob questions.

 

Nevermind I figured the keyless entery reprogram out. Its very easy. lol
