It's likely one of two things, either the door lock cylinder was replaced and not keyed to your actual key when the actuator was replaced, OR the lock cylinder has corroded and frozen in place. I would take the lock cylinder out and soak in WD40 or PB Blaster and see if it frees up. If it does then lubricate it with graphite and reinstall. If not, then make sure it is keyed to your key (if you don't know how to disassemble the cylinder and do this, a local locksmith can).

Problem #2: Keyfob buttons working intermittently
Sounds like the keyfob has just gone bad. Do you have a 2nd keyfob? Does it work? Probably need a new keyfob.
Thanks for the reply, Opie.

I worked on the door lock actuators myself with a friend who has made a living working on cars professionally, so with him knowing wtf he's doing much more than myself he did the majority of the work, I was pretty much a glorified panel puller and tool gofer for most of it, and we verified everything was functioning properly after the job was done. The lock cylinder itself was not changed. I may have to go back in there like you suggested and see if anything happened to it. If it were frozen/corroded, would it still be able to turn in either direction or would it be stuck and unable to move?

I did mention that I have two sets of keys, one basically brand new because it's lived its life as a spare that I thankfully haven't needed to make use of. Both keys experienced the same problems interacting with the car, batteries were replaced in both, and both required several button presses before either one got a response from the car.
