I have to replace a battery in my car. I have read that I will need a code to activate my radio. Is that true ?

What is your question?

My 2015 Buick Encore battery was dead this morning, this is first time I had to replace the battery in my car. Just let you know I purchase this car in 2017....So will everything like radio ..windows..locks..etc.. work fine when I reinstall a new battery or will I need a code to unlock these items I had mention..

How long has your 2015 Buick Encore had this problem?

this morning
