External Door Locks

[BobRivers]

I have noticed a few of our locks on the motorhome starting to stick a little. I read sometime ago on here not to use WD40. I have tried to find the thread but have had no luck. Was it more advisable to use Dry Silica or 3-1 instead of WD40?

I was told to use graphite powder on the key and put the key in and out of the lock a few times.

Could try GT85. That has PTFE in it.

Graphite powder

Graphite powder, tiny amount on a cleaned key.

Ambersil lock lube is very good, it's graphite based, silicone spray works but not as good.

I was told to use graphite powder on the key and put the key in and out of the lock a few times.

Works every time.

You are correct:

NEVER use WD40 on a lock!
It will fill the lock with sticky (fish) oil.

Graphite or Silicone based lubricants are the answer

Thanks everyone

I use graphite powder that's supplied in a container with a thin spout that you can push into the keyhole and puff in the graphite powder directly to the lock tumblers.
