Something must be binding even if it's clean and lubed.

Mine doesn't have power locks. Key lock works easy, but the inside lock button has always worked a little hard since new. Have you tried removing the rod from the power lock solenoid, then cycle the power lock switch to check for free movement? Then check the key lock movement to check that all is moving freely, also with the rod removed from the solenoid. The only maintenance that the shop manual shows is R&R of the solenoid. No trouble shooting info either.

Took top rod off no binding.That rod is the solenoid.If I used power locks it pushes the circle rod down to far.Then the key won,t turn to unlock the door.But with the rod off no problem

Can you bend that rod a little to make it shorter without interfering with something else?
