Outdoor Locks

[Lorek]

I was just wondering if anyone here has ever run into problems with master-keyed residential locks that are mounted outdoors on say a gate where the thumbturn is open to the elements. I've run across a couple of these where the locks tend to get stiff or jam up after a couple of weeks. After double checking the mastering for sliver's and finding none, I'm inclined to think its not staying lubricated. Any ideas?

Do the locks in question have any #1 master wafers? that is the most common problem with them getting jammed up. Most locksmiths will never use #1 masters at all. They are to small and tend to cause problems.

Oh, when I said slivers I meant Master #1's. I always use at least a two step when mastering. Too many problems with the #1's.

What type of weather are they being exposed to?

I recently sold a bronze american brand padlock, (5200 in bronze) to a neighbor, and repeated what a locksmith told me long ago, that bronze as a schackle on a padlock can be just as strong as steel. Given the modern alloys and all their properties, I would belive that this is true, or if the arguement gets stupid, you can compare it to mild steel and it will be harder.
However there is the verdigris thing, these locks can turn green in saltspray environments.
Does anyone have more on the bronze / steel variants? tell us what you know.

The weather's not too extreme, usually mid 70's to low 80's with changes in humidity just about every night. Unless it's going to rain then its between 60 and 70.

What are you using for lubrication?

[Lorek]

For residential locks I typically use Triflow.

[freakparade3]

I'd recommend using a silicone based lubricant. You can get them at any hardware store. They spray as a liquid and them dry to a waterproof film coating.

The problem you get with locks exposed to the weather is the mineral buildup from the moisture when it evaporates on the inner parts. Best to keep lubricated with a teflon lubricant like PT Blaster or Spray Lube Dry. Lock Saver is excellent but may not be readilly available. TriFlow is very good also. I like the dry type lubricants in keyways as some people don't like the residue on their keys as it tends to soil clothing.
