Coupler Fits:
This lock fits 2" ball couplers with a flat lip. Examples of some of the couplers it fits are pictured below.
This coupler lock has a disc tumbler locking mechanism. Unlike locks that use vulnerable spring-loaded pins, this ultra-secure lock is bump-proof. The cylinder has a series of rotating discs that can be correctly lined up only when you turn the corresponding key. Two identical notched keys are included to operate the lock. Because these keys feature 1 of nearly a million possible key codes, it's extremely unlikely that another individual will have a key that can open this lock.

What's up, everybody It's AJ with etrailer.com. Today, we're gonna be checking out this AMPLock coupler lock. It's going to fit on your trailer couplers that have the flat lip around there, and it has a two inch coupler on it. And what it's going to do is, it's gonna take up that space down here, so that nobody can mess with this when you're not around. So it's on there right now. Nobody can back up there and hook up to your trailer.
It's gonna prevent people from trying to use tools to get at it. You can see that this doesn't leave a whole lot of space to get in there and mess with anything. And most likely, they're just going to go to the next trailer that doesn't have any protection on it. Let's check it out. This lock's a little different from the other AMPLocks, the other ones have the second piece.
That's going to be the two inch ball that would fit up in this coupler and take up that space. Now I do like that style, because it doesn't leave any space in here. This one just has a pin that pops up and keeps it from coming off. So let me slide it back on there and show you. You just match up the grooves here with the flat lip.
It sits on there and you can just push that up, and now it's locked. That pin is now all up here and locking it tight. Another thing I want to point out, is this rounded plate here, it extends out just a little bit. And what this is going to do, is completely cover the portion underneath the coupler where their ball would be. That goes with the other one, having that complete ball in there.
This one has this plate to cover up that spot, so once it's up and on there, slid in, there's no access point to mess with it. Underneath, you can see the lock is a rotating disk tumbler, which is going to be resistant to drilling and lock picking. It also comes with two keys that are really easy to use. They go right in there and work really well. The whole thing's going to be cast iron and shock-absorbent. So that means if somebody was to hit it with a hammer, it would absorb that shock and not have any issues. Something else I would recommend getting is a coupler latch lock. It would feed in right here and lock up this latch, so that it can't be tampered with when you're not around either. Some things to consider before you order, is make sure it's going to fit on your trailer. It's going to fit a coupler width including the lip, of 4 3/8 of an inch. And then it's going to fit with the thickness of the lip, of 7/16 of an inch. Overall, I think it's gonna be a good addition to your trailer. Never hurts to keep it locked up when you're not around. Well, thanks for hanging out and I hope this helped..

Use this heavy-duty cast iron coupler lock to help prevent trailer towaway theft. Fits standard 2" ball couplers with flat lips. Resists picking, cutting, drilling, and freezing. Tumbler offers nearly 1 million possible key codes.This lock is a solid and hefty piece of equipment. Make sure to get the right model for your set-up. The width of the lip on my trailer was 3.75” and the lock fits like a glove.
I just got this new lock and have no long term experience. However, I have used and handled a lot of the so called locks on the market and I can tell you they’re cheap garbage. This lock weighs in at several pounds, and is a solid piece. The lock bolt action is smooth and comes with 3 keys. Installed on the trailer the fit is snug with no extra movement or sloppiness. I’m very impressed and feel good about this lock.
Seems like a great lock. Beefy lock and nice fit on my travel trailer, plus it is very simple to install and remove.
It was all that I expected strong and heavy duty. I will fish at ease knowing I have this lock on my trailer.
well, nobody has has tried to put a sledgehammer to it in the middle of the nite yet,but from the looks of it, I don't think it would hurt it much anyway. I like the design, an it looks very strong,an so far I'm happy. I like the way it locks.
It's terrific!

these are the best locks ever and locks can be keyed the same.

Review from a similar AMP Trailer Coupler Lock in Trailer Coupler Locks
The lock is heavy duty and great. But it DID NOT work on my 2022 Jayco Micro. The lock mechanism needs to be about ?” shorter to clear the lower lip of the trailer hitch. e trailer wanted a 20% restocking fee plus for me to pay for shipping since I was outside my return window. The trailer was in for service so I could not test it out before the return policy ended. So I am either going to sell it or try to modify it myself.I would not buy it again for my 2022 Jayco.

Tough Lock, Heavy Duty, Well Made, Rugged.

Review from a similar AMP Trailer Coupler Lock in Trailer Coupler Locks
This is the best I've found for a 20K Demco coupler. Easy to install, proprietary keys, really really good quality.If you see how its designed and works it'll help understand the cost.If I had a claim w the piece attached to this coupler, at least the insurance co would see I made every effort to protect my asset.Buy Once cry once. If someone gets past this to get your equipment,there was not much you could do to protect it. etrailer has done well carrying quality equipment.zero complaints.

It's built really well! No way anyone is getting it off the trailer without a cutting torch and that would be questionable!

This should provide the security we hope for while the trailer is parked unhitched at a horse show.

Review from a similar AMP Trailer Coupler Lock in Trailer Coupler Locks
These locks are such heavy duty locks that when we lost the key to our first one, we had to hire a locksmith to get the lock off. It was no easy task even for him! Ordering a second lock was easy, customer service is excellent and shipping prompt. I highly recommend this lock if safety of your work vehicles are a priority for you!
