This universal coupler lock protects your trailer from towaway theft. Lock codes to your vehicle's ignition key, and it's nearly impossible to pick or bump. Included lock, base plate with ball, and shackle fit most coupler and latch styles.
Features:
Specs:
Note: BOLT locks permanently code to only 1 vehicle. They cannot be re-coded or re-keyed.
To install this lock simply insert the ball into the coupler's ball socket. Insert the collar into the base plate until it's snug against your trailer latch and the holes align with the holes in the base plate. Insert the lock through the holes in the base plate, and use your vehicle's ignition key to secure it.
When you insert your own key into the cylinder, spring-loaded plate tumblers move up and down until they are matched exactly to that key. The first time the key is rotated, the cylinder is uniquely coded to that key. When the key is removed, the cylinder moves into the locked position. When the key is turned again, it will rotate to the unlocked position.

Hi, everybody. Andy here with etrailer.com. Let's take a look at this BOLT trailer coupler lock. Now this universal coupler lock is going to help deter theft by preventing trailer hookup while your trailer is unattended, and the lock cylinder is going to code to your vehicle's ignition key. So this is designed to work with the ignition keys of the vehicles that you see there on your screen. As you might know, BOLT locks permanently code to only one vehicle and they cannot be recoded or rekeyed.
So if you have one of those vehicles, the ignition key will work with this lock cylinder. Now going back to our coupler lock here, this is going to work with your 1 7/8-inch, 2-inch and 2 5/16-inch ball couplers. I currently have the 1 7/8-inch insert on, this will also work with your 2-inch, and this does come with a bolt that you can tighten down to secure that insert. And then if you're wanting to use your 2 5/16-inch ball coupler, you'll just loosen the bolt to remove it, and then replace it with this larger ball insert. So very easy to swap it out.
And this is going to be very flexible depending on the coupler that you have. I do have a 2-inch ball coupler here. And to install it, I went ahead and lifted the latch there. You're simply going to install the coupler onto that ball insert. So as you can see, that holds very securely.
And then you're going to take this collar and you want to insert the collar in the base plate where it's going to have the most contact with the latch, so it's going to be in the rear most part of the base plate for this coupler here. And then obviously, this will be a whole lot smoother operation using this on a coupler that's mounted onto a trailer. But what I'm going to do is just make this as tight as I can and then run the pin through the holes, lining that up. So let's see if I can easily do that here. And then once you have this run through, just like that, there we go.
(metal thuds) Then obviously you'll replace the cylinder. But I just wanted to show you, while I got the pin in the collar, I'm not able to lift up the latch, so I'm going to be secure on there. And so someone can't come by and easily take this off. So when you insert your own key into the cylinder, the spring loaded plate tumblers are going to move up and down until they are matched exactly to your key. And then the first time the key is rotated, the cylinder is going to be uniquely coded to that key. And then when the key is removed, the cylinder is going to move into the locked position. And then when the key is turned again, it's going to rotate to the unlocked position. So it's going to be a very easy set up with your ignition key. And so let me go ahead and just remove my coupler here. (metal thuds) And this is a very durable, I think, well-designed coupler lock. (metal thuds) And if you notice, we do have a red powder coat on the base plate. And the collar is a black powder coat. So not only does it look good, not only will that finish, I think, do a pretty good job of holding up, but because it's red, it's going to be highly visible. So if someone is looking to take a trailer away, they're going to see that red color and that's going to catch their attention and they're going to realize that this is a lock, and so they're going to move on to the trailer that is unattended and unsecured. So this does include an instruction sheet to make sure that you're using this the way that it's been designed. But I think that's going to wrap up our look today. I do hope that it's been helpful for you. Again, my name is Andy. Thank you for joining me.
Ratings & Reviews
I have purchased other hitch locks in the past. Most of them have exploded when hit with a large hammer, because I have lost the key. This lock is well built out of harden steel. The lock is keyed to the truck so I will never have to bring out the hammer, (even if I had to break out the hammer, I do not believe it will affect the lock). Thank you etrailer for bring it to my attention.
Ordered it and received it in two days, Outstanding, everything worked as expected. I now have the 5 padlocks, receiver lock, and trailer coupler lock all set up using my ignition key, I love the fact I don't have to use 7 different keys and always have the key with the truck. Great stuff.
Like most boat owners, I have a multitude of keys to keep up with for my trailer and boat - boat ignition, boat cabin, boat storage compartments, trailer coupler lock, trailer coupler latch, trailer receiver lock, etc. The Bolt lock allows me to match my car's ignition key to the trailer coupler latch which means I have one less key to deal with - something I definitely appreciate. Just be sure you order the right lock for your style car key - once they are coded they cannot be uncoded.
Excellent product, used it on my month long trip through Utah, to Yellowstone and home. had no problem with my Bolt lock, really cut down on the keys I had to carry, have it on my bed cover on my truck, the hitch ball and the hitch lock. Very happy with the product will look for other of their locks in the future.
Very happy with Etrailer indwell use them again as needed.
Prompt delivery without damage , adequate packaging, merchandise as advertised. The locks were easy to set, performed smoothly; would use this supplier again and recommend the company to others.
Really like that this works off my key and u don’t have to carry additional keys!! However, this only comes with 2 size balls, not 3 as advertised. I think it’s assumed if you have a 2” hitch, you will just use the 1-7/8 ball. But I can actually lock it (as tight as it will go) with the trailer locked in to it and still remove it easily. If it had an actual 2” ball, this wouldn’t happen, or if it could cinch down tighter, but I can’t get it to fit thru the next set of holes on the black piece. Love the idea, but unfortunately can’t recommend this product.
I purchased a receiver lock and 3 coupler locks made by Bolt. I have a habit of forgetting to lock the coupler to the ball and driving off with the lock and keys on the bumper. This has happened twice causing me to lose both my first set and spare set of keys. I learned of Bolt locks and their ability to be keyed with your vehicle door/ignition key. I received my locks today and the easy to follow instructions had me insert my truck key and turn it clockwise till it stopped. I now have 4 locks matched to my ignition key, so no more leaving the key on the bumper. The receiver loch snaps onto the hitch pin without the key, but the coupler lock needs the key in for locking (just what I needed). These locks aren't inexpensive, but e-trailer had the best price I found. Another good deal from e-trailer.
Took forever but given current international complications, it’s understandable . Thanks for your constant updates.
Great product and easy to use
Key programmed easy. Looks very strong. Hope no one will try to remove it.
Got my Bolt trailer coupler lock this afternoon. It was a lot easier than I thought to key. I got it on the trailer already.Great product!!
Thanks to Amy. She shipped this part and the third part that is on backorder will be shipped as soon as it comes in product is easy to key to your vehicle key.
Super easy to key lock to my Ram key. Trying to eliminate as many keys as I can. As you can see in the picture, I also got the matching BOLT receiver lock.
No weather cover as on their other locks, but it has a sliding internal cover similar to your car/truck door lock. Solid and beautifully finished.
Keyed to our 1996 f350 and using on our Demco hitch. Bought this with the plan to weld up some extensions covering the hitch bolts that connect to trailer. Should not be difficult since it is made from steel.
My 2010 Airstream trailer coupler has a curled lip on the collar which widens as you move toward the trailer. The 2-5/16" "ball" fit well as long as I slipped the U ring through the front slot of the red plate. I tried the back slot but the collar was too wide so the pin wouldn't go through. Using the front slot seems like the system will be secure enough but I would prefer using the back slot. The lock works perfectly with my 2014 Tundra key.
I don't have a center cut GM key just yet but my locksmith is hooking me up with an unused that's already been cut that he was using to bring perfection to the center cut key world when they were first introduced. I do know the bolt is the perfect size to replace the snap retainer on the yoke of our Curt 30K 5th wheel hitch to help keep it right where it's supposed to be, which is helping to protect our hitch to keep it from growing legs then strolling off the property. It's really discouraging when considering all the fellow brothers and sisters out there who are scheming, thinking up new ways to attempt to rip us off. I really never pictured 2025 to be so upside-down in the mindset between what's right and what's wrong. In the modern times, absolutely nothing is sacred or safe.
Works well but thought pin a bit long but maybe ok when combined with this complete tongue lock when parked. Again nice that it works with my Toyota tailgate key.
Best addition you can add for trailers. I never have to go looking for keys. Had this on my last truck for the receiver and trailer pins. Only gripe is those are now useless.
Using on my Aluma car trailer. Fits well and instructions well written. Can even combine with latch pin for added security. Uses my Toyota truck tailgate key as advertised.
I already owned one of these for my boat now I’m putting a second one on my utility trailer and I have one for my trailer hitch on my truck firm believer always nice to have only one key for all my toys
We've tried a TON of different coupler locks for our 2019 Jayco RV with an underslung coupler, and we ended up having to send them all back because they're too narrow. A year or two ago, after giving up on all the other brands from all the other sellers, I got on the phone with an e-trailer rep, and he dug through the available options to find one wide enough, and this one works!
Since it's keyed to the tow vehicle key, and since we sold our previous tow vehicle, I just bought another one because I KNEW it would fit, and it does. So thankful for this lock and for etrailer's help.
Good news is that it works like all B.O.L.T. locks I have with one key. Bad news is that there is no way to seat the cylinder COMPLETELY against the hitch, which leaves a small gap that a thief could get a hacksaw into. Still, the pros outweigh the cons.
Easy to use, works perfectly gets rid of unnecessary keys on ur key ring.
Excellent quality! Superior security! I have Bolt products on boat trailer and cargo trailer. The feature that all my Bolt products are all keyed to my ignition key sure comes in handy!
It’s great that I do not have to carry extra key, however it is loose. It has 1-7/8 and 2-5/16, however it does not have2 inch cup ball. It fits loosely on 2 inch balll cup.
