Yep it sounds like you lost the BCM fuse or the BCM when bad. Here is a door lock wiring diagrams so you can see how the system works and a guide to help you test the fuse

I also included a fuse panel location and identification.

Check out the diagrams (Below)

Let us know what happens and please upload pictures or videos of the problem.

Cheers

They can get weak over time or there is a short in the system if there is a short you will see the fuse pop again let me know if that happens.
