Specs:
This king pin 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, how's it going Today, we're gonna be going over and showing you how to install the AMPLock kingpin lock for 5th wheel trailers. So this coupler lock again is gonna be a great option for some of those people who either leave their trailer at the campgrounds permanently, or they head into town frequently with their tow vehicle, leaving their trailer unattended. You could also have your trailer parked at the house and you still just don't feel comfortable when you're away at work or if you leave town. This coupler lock here is gonna keep your trailer nice and secure. You don't have to have any worry about someone taking off with it. So this is what our trailer coupler lock looks like installed.
As you can see here, it's very beefy, heavy duty design, it's actually made out of cast iron, so you know it's gonna be super durable as well. Everything has a nice powder-coated finish, sort of this gray hammered finish. So it's gonna do a great job of protecting the lock from rust and corrosion, being that it is, again, installed on the outside here of our trailer, subjected to the elements. So if you haven't heard of AMPlock before, they make some phenomenal products. In fact, their coupler locks are widely regarded as some of the best locking options on the market.
And that's because they're pretty much bulletproof. There's pretty much no way that you're gonna be able to get this coupler lock off the trailer without your key. You can't pry it off you can't cut it off, you can't freeze it off and you won't be able to pick the lock core, due to the tumbler design. So granted, we don't wanna damage the trailer, so we're not gonna be doing any extreme measures, but just again, to show you guys how bulletproof this lock is, we've got a fairly large pry bar here. And if we sneak it below the skid plate here and above the trailer lock, and we really pry on that thing, you can see it is not going anywhere.
In fact, I would probably break this pry bar before the lock broke. So our pry bar didn't work. Let's go ahead and try a hammer now. So if we take a closer look, obviously the lock is still intact and on our trailer, but even where I was hitting this cast iron here with our hammer, it really didn't damage the finish too much. There's a couple of marks here, but most of it is still intact.
So we didn't have any luck with the hammer as well. So that's two out of three that won't work. Let's go ahead and try to pick the lock. Now, even for an experienced locksmith, they're not gonna be able to pick this lock, with their picking tools. I am by no means an experienced locksmith, but just to give you a representation with a standard pick here, you won't be able to free the lock from the coupler. We touched on this a little bit earlier, but due to the tumbler design of the keys, these keys are actually very, very hard to replicate. Now I do wanna point out that if you lose them, you can obtain replacements from the manufacturer. Just make sure you keep your blank here that has your key code, but again, you won't be able to remove this lock by picking it, either. So, something else you'll be glad to know, so with our lock cores here, we don't actually have to have our key to lock this on the trailer. Granted, we have to have the key to unlock it, obviously, but as you can see here, we don't have the key inserted. We'll place it in position. And all we do is just press in on that lock core there, and our lock is engaged. So just another added feature here, you don't actually have to have the keys to lock it on the trailer. So in regards to compatibility, this trailer coupler lock here is gonna work with most 5th wheel king pin pin boxes. There are a few that don't and that's gonna be the Sidewinder options from Reese. There is actually a separate lock for this exact purpose, but most of these standard pin boxes that come on your RV from the manufacturer are gonna work great here with this coupler lock. So our coupler lock here, you can see it's pretty bulletproof, but if anything we're to happen, you would be covered by a five-year warranty. The manufacturer does, however, recommend a quarterly maintenance, but all this entails is simply using a lubricant to lubricate the internal locking mechanism. So to start off our installation today, we're gonna be uncoupling the trailer from the tow vehicle, making sure we're on a nice flat and level surface. Then we're gonna level the trailer with our landing gear. And once we've done that, we're ready to install our coupler lock. We're going to rotate the included cap out and away from the lock core. Then we're gonna take the keys that come with our lock, we're gonna insert them into the core, and then we're gonna rotate them clockwise and then pull out. We'll rotate them back again so we can remove the key. Now, what we're going to do is, we're going to line up the kingpin with the opening inside our lock here. And then we're gonna push all the way up until it's flat against the bottom flange on the hitch. Now, what we can do is simply push in the lock core. Now, we're going to rotate the cap down to lock it in place. As you can see here, our lock is secure on the coupler of the king pin. Now we'll take our keys here. We'll put them in the vehicle or a safe place to where we don't lose them. And then when we're ready to tow, we'll simply open up the little dust cap here. We'll re-insert our key. Make sure you have a good hand on the coupler lock here. And then we'll go ahead and rotate the keys, pull the lock core out, and then we can drop the lock down and out of position. Now we're ready to tow. And that's gonna do it today for our look and installation of the AMPlock king pin lock for 5th wheel trailers..
Great people to deal with very informative.
Great product. Well made and will be a great deterrent.
Look forward to using them.
Quality product, easy order process and on time delivery!
works great
Awesome, very H.D., installs and removal is easy.
I was a bit skeptical purchasing online, but it fits our Pulltrite Capture Plate like a champion!!
Most definitely recommend this if you have a capture plate that is notched (Pullrite)!
Great product serves its purpose
Very beefy lock and fit perfectly. Another great buy and interaction with etrailer!
Excellent quality, will take some work to remove without the key. Simple to use, and fits like a glove.
My husband asked me to find a king pin lock for our new Fifth Wheel. I spent a lot of time searching the web. I finally found the Atwood AMPLock 5th Wheel King Pin Lock on this site. It looked so much more substantial than other locks I looked at. Yes, it came with a price, but when there are so many people out there that think what you own is their's for the taking I wasn't going with something that would be easy to break off. We like the features of this lock and by the way, my husband is very happy with my choice. We also received our purchase in a timely manner and in great condition. Thank you!
Wonderfully simple yet effective design. Intuitive operation. Nice.
Product works a advertised. The time from placing the order to receiving it was amazing fast! I will definitely be ordering from E- trailer again!
This lock is of the utmost quality a great investment for our new fifth wheel.
Product is exactly as I had hoped. Solid and heavy! The keyed lock and keys look robust and impenetrable.
Extremely nice lock, I was shocked on how heavy duty it is. The guys at etrailer know how to take care of the customer along with quick delivery. Way to go team...
I really like the heavy duty feel of this hitch lock. I plan on using it on my RV while traveling.
This lock is very impressive . Easy to use and works as advertised. Also, the service from Etrailer is second to none. I ordered it in the evening and was surprised , and pleased, when I was notified that it shipped first thing the next morning. I will be using Etrailer as my first choice to order equipment.
I am totally happy with the service and products of etrailer, the prices are great and the customer service is even better. I highly recommend etrailer to all of my friends! Thanks
This is the sturdiest lock I've ever seen for a king pin. It will work perfectly. Thanks etrailer, as usual you guys ROCK!!!!!!!
The king pin lock is very substantial and would be most difficult to remove without a torch. It's also easy to install and remove. Although it is more costly than the others, my peace of mind is worth it.
