I had to disassemble and clean all the locks on my Tristar. The factory
grease had become so hard, all the tumblers were stuck and any key would
open the door. I thoroughly cleaned the tumblers and all the hardware
before I reassembled with a light coating of anti-seize (all I had handy at
the time). Everything works crisply now.
Cheers,
Jeff

A light grease known as white lithium grease is often used on airplanes
to keep fine parts lubricated and water out. It is a very thin grease
but has enough body to stay put. Other lubes often used in the aircraft
world for lubing of finner parts were LPS (three different weights as I
recall), Marvels Mystery Oil (the penetrating oil - not the top lube
stuff). WD-40 also works but didn't make for the best lube over time
because it evaporates and/or runs off. It is really a water displacement
agent. There were also teflon spray products - one particular as I
recall called Treflon. Worked well in some applications. And once in a
blue moon graphite was used.
