Lubricating Truck Door Key Lock?

No grease!

Pull the lock cylinder if you can. Clean it out with brake cleaner and lube it with a dry graphite. Anything petroleum based will just attract dirt and grime and it will be sticky again.

 

Plus, do you have another copy of the key? Try it. It could be the key itself is what is getting worn.
And if not, see if the dealership will not rape you for a new key cut by the VIN, not by copying.

 

I don't know how you all put up without having the button on the keychain to unlock or lock it.

You should find better jobs.

 

I've heard this before that Freightliner will make the key for your truck. My truck is an older truck, a 1995. When I called Freightliner they absolutely told me positively no way would they make me a key. I have been afraid to have anyone else make me a key because I only have one. And I have gotten the outrageous prices like $100 to cut a key that's basically the same as an old Chevrolet key.

Does this kind of things vary from dealer to dealer?

 

Kroil oil.

 

For a 95 model find a old hardware store and have one cut. I’ve got a couple keys on my keychain now that I’d bet $100 will open your truck.
