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 2 inch Ball Coupler Lock Review

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..

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.

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!

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.

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.
