2005 Chevy Cobalt LT auto lock issues?

Just bought a used 2005 Chevy Cobalt LT 4 door, only issues presenting are the auto locks don't work on either door. You press them and they do nothing, the automatic mirrors do not move as well. However the Windows all go up and down just fine. I checked the fuses and they re all fine, any suggestions on what it could be?

When pressing the trunk button it makes a clanking like its trying to unlock but it can't and has to be opened with the key. Anything you can think of that would help fix that?

I bought a key fob off eBay for $12 thinking I could program it myself easily as I did with my last ford. Can't figure it out, reading something about a dealership? Thanks for your help guys, other than that cars mint and only paid $1200.

Do the door locks work with the inside button?

Hi so asking the same fool question twice does not get a better answer as it is just as worn out old heap.
