Nissan Repair: Audio does not work after I replaced the battery, operations manual, nissan

Question
My car is a 2004 Nissan Atlima. After I replaced the battery, audio does not work. Help me to fix it, please!

Answer
Hello -

This is an anti-theft device that once the audio loses power, it requires a code to be entered to reactivate. This code should be in your audio manual (not car operations manual) that came with the vehicle when it was new.

If you don't have the manual, then you will need to call the dealer to get instructions on how to reset. You will need to give them verification that you are the owner, though.

Hope this helps -
