New car battery Installed, now no alarm

[cdyer77]

My battery died the other day & recharging & driving didnt bring it back, so I went to autozone & got a replacement. Install went as easy as installing a new battery. But now my alarm doesnt work.

Is there something I have to do to get the alarm working again?

Please help.

Thanks!

After replacing the battery what all needed to be done to get the car defaulted again?

I guess this alarm thing and adding the code to the radio. I also heard something with pitch for the window? Anything else? I'm about to replace my battery and want to be prepared before doing it.


Thanks

I'm new to the Audi world, how do I know if the alarm is working or does my car even comes with one, I know when I locked it makes a really low beeping sound from the back of the car, but it doesn't make any sound when I unlock it tho, thx
