i haven't tried the locks manually yet as i don't use the buttons, my car locks the doors and un locks them for you when you shift from park it locks and unlocks when put back in to park, and i have key less entry.

i do have the back door lock actuator unhooked right now, it was making a loud noise when i first got it, and the lock was not working. found the noise and killed it by unplugging it. but thats been like that for 10 months now.
