Cargo and propane door latches.

My latches are getting harder to turn .The ones without keys. Can they be lubricated or should they be replaced. Thanks for any advice .

[H. John Kohl]

Yes I lubricated mine. Open them up and remove the screw and spray some lubricant in. Try getting the freed up. If that don't work then replace them.
This works for ones with keys too.

Don't use something like WD40 that will collect dirt and dust. Use a dry silicone or a graphite spray.

Thanks John And Dick. I will use the spray I put on the slides it's dust free.

Yeah, I'm having the same issue with my barrel locks. Lubricant sounds like a good idea after adjusting the tightness.
