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 amp lock, coupler lock, and this is going to be good for those flat lip trailers on the front and with a two inch coupler. So, you're going to be able to put this on the front of your trailer, lock it up, and you can see it's blocking anybody for messing with the front here on this coupler. The ball is actually in there, blocking that space, and you can't get a tool in there to mess with that or even hook it up to a trailer. It's nice and secure when you're not around.
Let's check it out. So now, the lock comes in two different pieces. So we got this part, which is the two inch ball, that's going to go up in the coupler and fill this whole space, which is good because that's what sets it apart from the other locks. Sometimes they just have a pin that goes in there or just a little covering. This is going to fill up that entire space just like it would, if you we're hooked up to your truck.
That way, again, like I said, you can't get any tools in there or force anything in there to try and tow it out. So then, with that in there, you put it in the second piece and this is where that flat lip is going to fit in. Just push it on like that. And then we can push in the cylinder at the bottom. That's locked in place.
Look, in the bottom down here, you got a rotating disc coupler, and that's going to be the way it locks up and it's going to be resistant to drilling and lock-picking. Now, it comes with two keys. And then all you gotta do, is go under here, wind it up, rotate it until the cylinder comes out, just like that. And that's what makes it unlock. Looking out the side, this portion is going to be cast iron.
So it's going to be shock-absorbent. That means if you we're to hit with a hammer, it would be able to absorb that force, and not cause any problems. One thing I'd probably add though, is if you're going to go through the trouble of getting a lock and put it on your coupler, I would go and get a locking pin for here, for the coupler release. So you're gonna put that through here and have the lock on that side. We have plenty of those on the website. I would look at one of those just to go ahead and lock this up, lock this up, that way nobody can mess with any of it. You're gonna want to make sure this fits on your trailer coupler before you get it. So, to explain that, it's going to go and fit on trailer couplers with up to four inches. And it's going to fit on the thickness of three eights of an inch. Overall, I think it's worked great for your trailer. Never hurts to add that extra theft to turn on there like this lock. It's going to be on the front. Somebody walks by and they're more likely to look at that and go, "I'm not going to mess with it." Move on to the next trailer. But I think that does it. Thanks for hanging out and I hope this helped!.

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.
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.
Tough Lock, Heavy Duty, Well Made, Rugged.
I do believe that this will send a potential trailer thief looking for another trailer.
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.
Heavy duty item! It is a little looser when installed than I thought it would be but I understand it fits many different hitch types. Even though it does fit a little loose in my opinion, in no way would anyone be able to get it off!
Easy to use. Heavy duty. Seems very sec ure.
We chose AmpLock because after thorough research we found that this was the must trusted anti-theft device for our travel trailer. We often go out and leave our dogs in the trailer while camping and we didn't want to have to worry about something happening to them should the trailer get stolen. This gives us extra piece of mind. I hope that we don't ever have to find out how well it works, but for now we are very satisfied with our purchase. It did fit perfectly and was easy to install as well.
Trailer still where I parked it. This lock is doing its job.
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.
Kate was extremely professional and knowledgeable about the trailer coupler lock that I needed. She was very efficient and helpful in placing the order and when the lock arrived it fits perfectly. It is on my trailer right now and is exactly what I needed thanks to Kate and her performance. Give her a big monetary raise and recognition before her peers.
This is a nice lock, but there is plenty of room between the lip of the lock and the body of the trailer coupler for a prybar to be used. The coupler does have quite a bit of 'play' when installed - probably because it is a universal lock and as such it is designed to accommodate the dimensional differences between coupler manufacturers. Overall, the quality is very nice, and I have some ideas regarding how to 'tighten' up the fit between the lock and the coupler via shims. The manufacturer should consider including some shims - which could be used to provide a better fit between the lock body and the coupler.
Very well built, I like jow heavy it is
Heavy, high quality. Hope it keeps the honest people honest. Time will tell.
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.
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.
Seems like a well engineered system. No one has stolen my trailer yet.
Fit over hitch perfectly. Lock mechanism was smooth and orientation down so water/ice don't get into the tumblers and freeze the lock
Nice trailer lock, its expensive but if some one steals the boat it would be very in expensive then. :)
Great heavy duty lock. Have put it on at every stop, we feel secure leaving our home knowing it’s not going anywhere. The lock hole being on the bottom of the unit is a bit of a pain at times but would also make it harder for someone to pick it. Over all I am happy with my purchase
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.
