Secure Locking Mechanism

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.

Video Transcript for AMPLock Flat Lip Ball Couplers Trailer Coupler Lock Review

What's up, everybody, it's AJ, with etrailer.com. Today, we're gonna be checking out this coupler lock from AMPLocks. Now this is going to work with your coupler on your trailer, and what it's gonna do, is you're gonna put the ball in the coupler, and the lock along the lip, and then it should be all locked up and nobody can mess with it, let's check it out. It's a real easy process, first you're going to put the ball up here in the coupler like you normally would. Lock that into place, and you can see it's locked in there, it's not going to go anywhere. And then we add the second part of the lock, which this part here, it's going to fit it right over the flat lip of our coupler.

And you're gonna line up this with the hole on the ball there, just slide it into place, and then lock it up. So now that ball has taken out that empty space here in the coupler, so nobody can get anything up there to wedge it out, and this is covering up the front of it too, so that's just like double protection. so people can't mess with this coupler. It's actually a pretty snug fit on our coupler today, it's moving back and forth but there isn't a lot of space and then there's not a lot of gaps, so let's test that out with a pry bar. Just going to put that into place.

Yeah, it looks like it will fit in there and you can push on it a little bit, but it's not moving anywhere. I'm not pushing that hard, but it's still staying in place pretty good. Looks like it can fit in under here on the side too, now this way, I can't really pry against anything. This way I might be able to just a little bit, but it really does take up a lot of those gaps, I mean, there's not an easy way to get this in there. So if somebody wasn't messing with it, it would take them quite a bit of time to get in there and do anything.

I think they would probably just walk on to the next trailer that doesn't have a lock on it. Another good thing to test is to see, with the latch undone, it's not going to just drop back out, it doesn't drop that ball. This is working in combination with that ball to keep this locked up nice and tight. So even if you don't have a locking pin that goes in there to keep that from moving, you still can't just get it out of that easily. Another thing to note is here at the bottom, the tumbler lock.

And I really liked that because it's going to be resistant to drilling and picking, and it's got like a million different combinations or possibilities for the key. So, chances are no one's going to have the same key and they're not going to mess with it to try and get in there. And it does come with two keys you get, and you see I just turned that and pop that button out, and that means it's disengaged. When you want to go to lock it, you just push it into place and it's locked. It's nice that when you go to set this up, you don't have to have the key in there to lock it. I like that push button 'cause you can just do that, and your keys on the side. The construction is cast iron with an E-coating so you don't have to worry about the elements bothering it at all, so if you leave it out here and it rains, or anything like that, it's not going to rust or corrode on you. The other thing is it's going to be shock absorbent, so if somebody was hit with a hammer, it wouldn't just shatter, it would absorb that shock. Taking a look at the inside of the coupler, this is going to fit trailers of coupler widths of 4-9/16" of an inch, and then a thickness lip of 7/16" of an inch. So just keep that in mind when you're looking at your trailer, this is the one that's going to fit. Overall, I really like this lock. I like that the two-in-one combo is pretty heavy duty too, I like the fact that this covers up the front of the coupler, and this is gonna take up that space on the inside. So like you saw with the pry bar, it's gonna be hard to get those angles and get in there, and like I said before, pretty sure people don't take one look at this and go, "I'm not messing with that," and going to the next trailer. Thanks for hanging out, and I hope this helps..

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.

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!

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.

Review from a similar AMP Trailer Coupler Lock in Trailer Coupler Locks


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.
