“Weatherproof” padlocks for boat/trailers

Anybody have a recommendation for boat and trailer padlocks? I would likely need a set of four and want them to be keyed same. 2 for trailer doors, one for enclosed trailer tongue, and one for boat trailer tongue.
I would buy a 5th if sizing worked out to use to secure mu ulterra on the mounting plate, as well. The master locks I’ve used the last few years had the plastic cover for the keyhole, but in upper Midwest winter weather always require me to put a lighter on the keyhole for about 30 seconds in order to be able to turn the key.

They all freeze. Their tolerances are too loose, lube and heat are your friends.

One day I’m gonna buy me one of those cordless heat guns. Safer than a torch, but more oomph than a hair dryer (and cordless as well)

Combination locks?

I use the standard keyed master locks and just spray them. Had the same locks on the boat (tongue and for spare) for 5 years with no issues. My boat is outside about 90% of the year.

Zep 45 or jb 80 sprayed all over in the lock and in the locker. I apply zep to my trailer tongue pad lock and my hitch lock. Zep seems to last the longest between applications but I try to spray them once a month of I remember. Wd 40 works but It doesn’t seem to last near as long before corrosion starts. Jb80 is great as well but I hate the smell. I run master pad locks I have probably 15 pad locks with the same key.

How often do you spray the WD40/Zeb45/JB80? Seems like the locks on my enclosed trailer (side door and back door) are the main issue when traveling with snowmobile/atv for ice fishing.

I just do it as I remember. I have a can of wd40 in the truck under the seats. When I see the can I usually spray the locks.

Yeah just keep a can on hand in the box of truck or in your road side kit. Spray it once a month in the winter the keep it well lubed. Early and late season my snowmobile trailer sees alot of salt so that pad lock gets lubed more often then the other trailers. Just be liberal with what ever product you use. You can’t over lube it.

Like BC says, You can never have too much lube!

^That’s the perfect defense.

Maybe P-Diddy just owned a bunch of trailers with locks on them, and baby oil worked the same as WD-40?!?

The best I’ve seen/used. https://infiniterule.com/

Not cheap but imo worth every penny. I got the 3 pack #61633 ($185) – Trailer Tongue lock, Coupler lock, Hitch pin lock ALL keyed the same (6 keys total). And 2 other coupler locks. BUT the last I will ever buy. Plus you can order next year and get the same key. They even make one for the Demco coupler on my Aluma trailer. Stainless steel and made in USA. Highly recommend.

Oil collects dirt. They recommend 3-in-One Lock Dry Lube. $5 at L&M.

Can of jb80 stay ok in high and low temps? Dont want anything going boom…

I have a case of zep in my work truck 24/7. In this brutal cold you’ll have to warm the can a little to use.

I’ve used the brass Master padlocks for over 30 years. Great locks. As others have said, the main problem with padlocks is water getting in them and freezing. A couple of shots of WD-40 every once in awhile really keeps things moving well.

Thanks, all. I have a can of JB80 and will keep it in the truck to give the locks a spray now and again. Also planning to pick up a small 3 in 1 Lock Dry can.

Might be a silly question but why travel with the locks on in the first place? I get sitting in the driveway but why not take them off while traveling where the roads will do the worst damage.

The pad locks on my trailers are also my hitch pins. So spraying them is a must. But I bought 6 or 10 pad locks all keyed the same probably 6 years ago. So just praying them with zep does the trick. It’s the same thing on my box truck. I have a pad lock on the side barn door and my back door. Just spray with zep and they stay functional

Never really thought about that…just leave them on. Security so the doors don’t pop open, I guess.

I’ve been using a can of Amsoil MP the last few years on all of my outdoor locks with good results.
Use it on the trailer tongue lock, hitch pin lock, and keyed Masterlocks on the chain for the spare, the trolling motor plate and swing away tongue pin.

When mine do freeze I like to heat the key. I HATE it when they freeze. Happens all the time on my snowmobile trailer that just sits in the yard. I fashioned some plastic water bottles around them once and that worked pretty good but that wont work trailering. Like others said keep drowning them in lubricant/solvent.

In a pinch use a piece of hose from tail pipe to the lock. The exhaust heat thaws it out quickly but is not a long term fix like lube.

That JB80 seems to be pretty amazing stuff. Sprayed the locks, coupler, trailer hinges….spray Spray SPRAY!!!

Jb80 is twice as good at wd 40 lol

I haven’t used JB80, but I do know that Schaefer’s version Penetro 90 is awesome. I’m assuming they are roughly the same thing? The rep that stops here started leaving cans for us to try and we quickly converted to it as the “do everything” spray for tools, machines, or whatever else is worked on around the buildings.
