Default Replacing tough locks on an 81

I have a '81 C3 with the power windows and power locks, and I'm looking to do a refresh. The power locks work well, but, man, it can be tough to unlock. I feel like I might break a key!

I've had some issues where I actually have to open the passenger side, reach in and trigger the power unlock to get the driver's side to open as the key won't do it. I'm worried I'm going to get completed locked out.

So, here is my question. I'd like to tear down the door and replace whatever I need to get the door locks working well again. Bonus points if I could install a keyless lock/unlock while at it. Any points to a kit or what I'll need to get rolling on this.

You might not need to replace anything. A good cleaning and lubing usually does the trick.

Interesting. Are we talking about the actuator specifically? Any areas that I definitely want to hit?

I ended up replacing the lock actuators, along with cleaning and lubing. If your actuators are in good shape, hopefully you can skip this step.

I don't recall which instructions I followed, but here's what Grok suggested today.

More than likely the main door latch mechanism is all gummed up.
