The Master Lock Universal Trailer Coupler Lock, part # 379DAT, is designed to work on all three hitch ball sizes, 1-7/8 inch, 2-inch, and 2-5/16 inches. Since it fits all three sizes it will not be able to be very tight, but you will want to make sure to slide the body of the lock up against the coupler as far as possible when attaching the lock to the coupler.
As long as the lock cannot be removed after you lock it to the coupler it will work just fine in keeping somebody from connecting... view full answer...
There are two different size cone's with the BOLT Trailer Coupler Lock part # BL7032493. The small cone is for 1-7/8" and 2" trailer couplers whereas the large cone is for 2-5/16" trailer couplers. There are several different types of trailer couplers which means that this lock will not be a perfect match for all. If the lock will not stay in place while using the smaller disc then it can be returned under warranty. These will be a bit of play inside the coupler but the lock should still... view full answer...
I can absolutely explain how the etrailer Trailer Coupler Lock for your flat lip coupler works, and it is extremely simple.
What happens is you will slide the lock over your flat lip coupler, and push the pin up - it won't take any strength at all, you can do it with a finger. With the pin up, just turn the key and you're done; it's locked to the coupler. When you want to remove it, turn the key in the opposite direction and the pin will come down. That's literally all there is to it!... view full answer...
There are a couple of different ways you can lock the Curt QuickPin No-Latch Trailer Coupler for 2" Ball, either with a standard coupler lock, or you can use a 1/2 inch diameter hitch pin lock, since that is the same size as the pin and clip (though you should always use the pin and clip that come with the coupler when towing and not a lock).
So to lock it you can use any of the following options, depending on what you prefer:

In order to get this setup, you want to start with the Lock N Roll Articulating Trailer Hitch for 2" Receivers # 336VS501. This will fit the 2" receiver on the hitch on your vehicle.
For the trailer side, you will need to remove the current coupler and choose the correct Lock N Roll Articulating Channel Tongue Trailer Coupler based on the tongue of your trailer. We have the following options available:

I only had one photo of yours come through so it is a little hard to tell but you should be able to add your padlock style coupler lock, like the Master Lock # 605DAT, to keep your coupler from opening.
Attached is a review video of the discontinued Atwood Yoke style coupler AT80072 where you can see that the padlock would attach to. I'm guessing you've already tried attaching the lock and you are still able to open up the coupler with the trailer coupled to your tow vehicle? If that is... view full answer...
There will be no safety issues and you can absolutely back up with the Lock N Roll articulating coupler, no matter which one you use. Backing straight up won't be problematic and it will even be a bit easier to maneuver when turning due to the articulation. I'm not sure what coupler you need for your trailer, so here are all the trailer-side Lock N Roll couplers:
- 2" Channel: Lock N Roll Articulating Coupler # 336TS528
- 2-1/2" Channel: Lock N Roll Articulating Coupler # 336TS506

While the 2-5/16 inch ball of the # C48CR would fit into a gooseneck coupler the pin portion would not have a place to insert to lock it. You'd want a gooseneck coupler lock like the EZ Lock Gooseneck Coupler Lock part # BLTL-53-40D2 which fits most couplers like Bulldog, Stallion, Superior, and T.E.M. view full answer...
The Trailer Coupler Lock # e98886 prevents the latch of the coupler from opening. So if you installed this lock on the latch of your trailer like in the picture attached to this page someone could lower the coupler onto their ball and the ball would support the weight of the trailer, but the coupler would not be able to secure to the ball.
So basically if the thief were to hit a big enough bump to unload the tongue weight of the trailer it would fall right off. Or if they drove up a steep... view full answer...
The Masterlock trailer lock set part # 3794DAT does come with a ball mount lock, a pin lock, and a coupler lock that are all keyed alike like you are looking for. view full answer...
The BOLT Trailer Coupler Lock - 1-7/8", 2", and 2-5/16" Couplers - For Ford Side Cut Key # BL7032496 comes with two different integrated balls. These don't look like your traditional hitch ball since they are not designed for towing. The ball is the round silver piece you can see mounted to the base plate below the shackle. The smaller ball fits a 1-7/8" and 2" coupler and the larger ball fits the 2-5/16" coupler. view full answer...
According to Lock N Roll, their # 336TS508 articulating trailer coupler is meant to be bolted or welded into place. They don't recommend using a locking hitch pin to mount the coupler. view full answer...
Due to the thickness of the top of the coupler, you wouldn't be able to lower the pintle all the way when used on a regular coupler. You'd be better off using a coupler lock to prevent the coupler from being unhooked. The best lock for you will depend on the design of your coupler. If you have a latch style, a lock like the Bulldog # BD580403 would be an excellent choice, and could be used while towing.

It's not uncommon to have to drill new holes on a trailer tongue to install a new coupler as most couplers have unique bolt hole spacings. That said there isn't an exact dimension I can give you on what you are asking for. Moving the coupler forward on the trailer frame would be what you'd need to do to install new holes. As long as both holes are being utilized and at least an inch away from the old holes (roughly) you'll be fine. You'll have to use your best judgment. view full answer...
Yes, you can use the Trailer Coupler Lock part # e98888 to prevent the hitch ball from coming uncoupled from the Demco 50-Degree A-Frame Trailer Coupler part # DM16680-52. The lock will install in the pin hole directly below the latch which you can see in the attached photo. view full answer...
Basically, the Gooseneck Trailer Lock, # BLTL-50-40D, sandwiches around the bottom of the gooseneck coupler on the trailer. The two hooks that look like duck heads go over the lip on one side and then you hold it up flat against the bottom of the coupler, and then you insert the pin that will be over the lip on the other side of the coupler. view full answer...
You are correct that there isn't a lock made specifically for this kind of off-road coupler, the Ark Articulating Off-Road Coupler for 2" Receivers - Trailer Side # AR44FR.
Since it mounts inside an off-road trailer's hitch tube like the Buyers Products Black Receiver Tube # 337RT25806B, the best way to secure it is to remove the coupler from your trailer when it is not being used and lock it in your vehicle, so your trailer would not be able to be towed away.

While I completely understand it can be a bit of a pain and more time-consuming than you'd like, I have to recommend you only use the included bolts that come with an adjustable channel trailer coupler such as # CTA-400. Using these bolts (which are grade 8 bolts) ensure the coupler maintains its capacity and stability for the safest towing set up.
I know it's not the answer you were looking for but the only option to help prevent theft is to add a lock to the latch, the Master Lock Adjustable... view full answer...
The Curt Pintle Hook with 2-5/16" Hitch Ball - Channel Mount - 20,000 lbs # C45922 would technically be able to lock in place over a coupler if the coupler were reduced in size along with the hitch ball itself. The huge issue is that when you change the coupler and the hitch ball you will drastically change the capacity of both the hitch and the coupler. This in no way is a safe practice as both capacity rated parts would be altered. In addition the hitch ball and coupler wouldn't rotate... view full answer...
I suppose nothing is stopping a thief from ordering the Fastway Universal Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers - Key 320 # FA86-0015-320.
That said, it seems pretty impractical and slow in practice to carry the keys, then find a trailer with this coupler, and go through each key to find what unlocks it. Realistically, a thief is almost certainly more likely to move on to a trailer with no lock at all as it would just be far quicker and less risky. view full answer...
