I used Lock Ease Graphited Fluid. I don't know if power locks would work because I have no remote. I have to use the key manually to unlock the locks and the driver side is malfunctioning. Pretty confident its the lock cylinder.welcome to the forum! what kind of lube did you use? Does the power lock work inside the vehicle?
You used the correct fluid for the cylinder. You don't want any oils or other solvents (silicone, WD40, white lithium, etc.) getting into the lock cylinder since they are known to gum up over time. Graphite is the only thing that can safely go in and lubricate the pins without them sticking in the future. Having said that, I've owned cars since the early 80s and have never had to lubricate a car's lock tumbler.I used Lock Ease Graphited Fluid.
