Specs:
This lunette ring 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.

Hey, everybody. Welcome to etrailer.com. I'm Bobby. And today we're taking a look at the AMPLock trailer coupler lock for lunette rings. So as you can see, we actually do have two versions for us today. We do have our three inch lunette ring version and our two and a half.
So I'll go ahead and make sure we are measuring that inner diameter on our lunette rings to make sure we have the right one to fit our trailer. Now, this is going to be a great little way of going ahead and securing our lunette ring that when anybody hook up to it, so therefore our trailer may be sitting wherever we leave it unattended. We have that nice peace of mind for ourselves. So you are getting the nice little stainless steel construction on this guy. It's going to work great.
And it's really, really simple to go ahead, take a closer look. See how we get this installed. Can you guys can see, we have a nice little fabric covering our outside chain, making our holding that much easier for ourselves. It's a pretty little simple device here, guys. You're seeing these two little balls right here that are preventing us from actually putting this on.
Of course that's what's preventing it from coming out when we actually get it installed. And there's certain accessing that we just want to simply slide over this cub cover plate here to access our tumblers. Now on the inside, you're having a ton of rotating desk and an AMPLock likes to point out you're getting a million different combinations with this. So you will need a very specific key that it comes with. So we got to go ahead and insert it like so, and just simply turn it to unlock it.
Then we can slide that up and out of the way as you guys can see, that's going to be pulling those balls into position. Allowing us to simply insert it, turn our key back out. Exposing those as well and preventing it from lifting out. So very little simple way of getting this installed and it's definitely going to work great. A lot of times when you're seeing lunette rings, you have a second assembling. You use it to put that one on the bottom one. Then the second one on top. I like how I can just simply walk up, pull that key out, pull those tumblers and drop it in place and then simply lock it right away. I mean, look at that. It's so easy. You can be hanging in there. Now, you are seeing it's just a little loose in there. However, I think it's actually doing a really good job and that can be popping out. Let's go ahead and stress test it a little bit. So we're just going to go ahead and try and see if we can pop this guy out. We just got a little rubber mallet here for ourselves today. It is pretty thick, you guys can see, we are seeing that exposed hammerhead on the bottom there. So we know it's going to do some pretty good work here. Let's go ahead, take a few swings. So I'm not seeing anything pop in that movement or anything. That stainless is holding up quite nice for us as well. That ball seems to be free spinning, so we're not damaging the inside of it anyway. And also as you guys can see, it's definitely not coming out at all. So even with me prying on it, you can see no movement from it. So I'm liking that those balls are staying in position, even with that tumbler being down. And I don't think we're going to get this guy out anytime soon. As you guys saw it seemed to be doing a pretty good job of standing up to our stress test. Now, obviously it's only a few whacks of a hammer, but I definitely am liking the stainless steel that makes for sure that it's going to be a nice strong product for ourselves. And I am a really big fan of those rate rotating desks. I definitely don't think I'd have an easy time getting in there. Of course it is nice that we are getting those two spare keys as well. And it's really easy just to walk right up, take that out, simply walk it away. I mean, it's really easy to go ahead, do that. I can see us too at the job site. Just drop into some place and leaving it for the weekend and having that nice peace of mind for ourselves. Well guys, I think that that's going to do it for our look at the AMPLock trailer coupler lock for lunette rings here at etrailer.com. I'm Bobby, thank you for watching..

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.
Impressive lock. Well machined.
I was disappointed I couldn’t engage ball with the hitch ball clamp assembly after the flange lock was installed.
This is a BEAST of a lock. The only way this is being removed without the key is with a torch and then welding a new trailer tow receiver back on to your trailer.
Trailer still where I parked it. This lock is doing its job.
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 the best trailer tung lock I have ever used. Heavy duty, well built, with a very unique key system that was well thought out. YES, I would highly recommend the AMP LOCK SYSTEM FOR YOUR TRAILER. YOU WONT BE DISAPPOINTED.
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.
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.
I am impressed with the quality of the lock. The day we put it on in Buffalo, our sons bikes were stolen out of his garage. We were parked right in front of it. We were happy to have had it on.
AMPLock coupler lock is fantastic. Used daily. Very well made, strong and def trust regularly to keep my trailer safe.
Nice trailer lock, its expensive but if some one steals the boat it would be very in expensive then. :)
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.
Easy to use. Heavy duty. Seems very sec ure.
It is a little large for my 2", it fit my trailer with a 2 1/2" coupler, I wouldn't get another one.
Fit and finish are perfect Fits the Demco no lip 25K
Does its job as advertised. I leave this trailer on construction sites, and no attempted thefts yet.
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.
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.
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 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.
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.
