will a 04 alero radio fit in a 2000 alero. plug and play ?

If it has thieft lock then you will need the code to unlock it.

I heard the pins changed in 01, not sure though

Pins are different from 2000 to newer years. It will physically fit but not plug-and-play.

You would have to re-pin the radio harness and add in a class-2 data bus wire. Then it would work.

Most people would probably would say it's not worth it.
