This coupler pin lock ensures that your trailer is securely hitched and helps keep it safe from theft while being stored. With this lock, you won't have to carry an additional key - it codes to your vehicle's ignition key.
Features:
Specs:
Note: BOLT locks permanently code to only 1 vehicle. They cannot be re-coded or re-keyed.
Are you tired of carrying a bulky ring of keys - for your hitch lock and coupler lock, your pickup cover or trailer door, and all the various padlocks securing your equipment? Tired of fumbling for the right key or having to replace a lost key?
BOLT (Breakthrough One-key Lock Technology) has solved that problem by designing a line of locks that can operate with a key you already have handy - your vehicle ignition key.
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.
BOLT is particularly useful in commercial applications. Imagine being able to send a crew without having to sign out multiple keys for a work truck, trailer, hitch pins, and equipment locks. With BOLT, the vehicle key becomes a master key. It opens all those locks and you no longer have the hassle of getting to a work site only to find that you've brought the wrong keys.

Today we're going to be taking a look at the Bolt line of trailer coupler locks. These are designed to fit with your standard ignition key. They can be keyed to Ford, Chevy, GM, Nissan, Toyota, just about whatever you got. They use an automotive quality lock. It has a six-plate tumbler that's going to prevent it from being picked. There's a stainless steel shutter that you can see right here.
That keeps dirt and debris out of our cast zinc cylinder. It's going to give us superior corrosion resistance. It attaches to the stainless steel rust-proof shaft using a double ball bearing, and it's going to lock automatically when the key is removed. They make these right here in the United States and they're going to offer a limited lifetime warranty. Now to get our lock set up we're simply going to take our ignition key, our key that we're going to use everyday with our vehicle. We're going to place it right into the lock and we turn it all the way over until it stops.
At that point our lock is unlocked and our tumbler is keyed. That's all there is to it. As you'll see here now we can slide it right down in there, get our secure fit. These are adjustable anywhere from 1/2" all the way up to 3-3/8". That's on an 1/8" increment.
We've got several different spots there where we can get it connected to give us a good snug fit. Now that we've gone over how it works, we'll show you how to use it on your trailer. Here on our trailer we're just going to slide the pin right through our coupler. We'll bring our bolt lock onto the other side. We'll then just turn our key and remove it. When we're ready to head down the road we'll know that nobody's going to be able to remove the trailer from our vehicle or hook up to it when our trailer's unattended.
To remove it we'll just place our ignition key in, give it a turn, and pull it right off. Now that we've seen how it works and we've gone over all the features, that will complete today's look at Bolt line of trailer coupler locks. .

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.
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.
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.
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.
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!
Easy to code to car key.
Love it!
Does it’s job with a secure lock!
WORKS GREAT, NO EXTRA KEY . WORKS WITH MY CAR KEY.
Works well. I haven't tried to defeat it but it seems relatively difficult.
Product was delivered quickly as is the hallmark of dealing with E-trailer. This is a nice quality coupler lock that uses my Nissan Frontier key. Programming to my key was easy and straightforward. Looking forward to providing security for my new trailer.
Love the concept and gets rid of a few more keys. Already placed it on the boat trailer and looks very theft deterent.
Good solid lock and coding it to your existing key is as easy as sticking it in the lock and turning until it clicks. My only complaint about this is you need the key to insert and remove the lock. I would prefer to only need the key for removal and hot locking my trailer coupler to the ball. Now I don't need to carry additional lock keys with me, as it uses my factory Nissan car key.
Perfect
Don’t need a different key. Just use the ignition key.

Still works perfect , but I did lose one bar for a trailer lock. So that one is unusable.
