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.
Has worked flawlessly for over a year stored outdoors in Chicago. Finish seems to be holding up and the action still works smooth. This is a very robust design that would be difficult to defeat.
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.
Arrived very quickly and is very HEAVY duty.
Should work great so I can relax.
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 was all that I expected strong and heavy duty. I will fish at ease knowing I have this lock on my trailer.
You guys always have everything I need. Always quick on your shipping.
Best service,also good hitch lock.
It's terrific!
Easy to install. Does the job!
these are the best locks ever and locks can be keyed the same.
well made. works very smooth. strong.
Impressive lock. Well machined.
I was disappointed I couldn’t engage ball with the hitch ball clamp assembly after the flange lock was installed.
Good tight fit, tough construction, and a disk core. It has sat out in the elements it's whole life and the lock still spins like new. I did drop the ball portion with the key still in it and it bent the key. That's my fault though. I Like the lock.
I have a car hauler with 2 inch receiver rolled lip. This coupler lock has what I wanted. It should prevent the opportunitistic thief from taking trailer.its a solid lock . I leave a trailer off-site so it's just added insurance. It will take some grinding to get off. Key is heavy and solid so shouldn't break in lock. Happy with purchase.
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.
This AMP Lock Trailer Coupler Lock might be expensive but you get what you pay for here I believe. I have purchased 3 of these based on what I believe to be a quality product.
I had a friend recommend this to me a year ago. Excellent lock for securing my car hauler! I recommend this to anyone that needs a trailer lock.
Nice lock for my Air Stream Bambi, just what I needed, between this lock and my new wheel chuck locks from Etrailer.com it should not get stolen again. thanks Etrailer for my new lock setup.!
Solid made, would be very very time consuming to overcome this lock , The lock cylinder is on the bottom, is harder to get to for locking and unlocking, That's ok is harder for thief to overcome it, This lock is well made and very heavy, Im glad to have this.
