Over a month later and i'm finally repairing. Still need some help from the pros on here

I have disassembled the drivers side front door, to first replace the carrier. Did in fact find the old carrier to be broken, so that should solve the handle opening problem.

Before reinstalling I was messing with the key lock, on the bench. The key does not turn the stem on the lock. I assume this means i need a new lock cylinder assembly, and from what i gather takes a few weeks to be keyed to my x5?

I removed the door lock actuator, and it does not move up and down when I grab the post (the part that comes through the top of the door panel) - I believe this means i need a new actuator?

Need any help you can provide. I want to put this thing back together asap
