Key Compatibility

Diagram showing compatible key styles

Installation

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.

Video Transcript for Let’s Check Out the BOLT Trailer Coupler Lock

Hello, everybody. This is Jeff at etrailer.com. Today we're gonna take a look at the Bolt Trailer and Coupler Lock for the Nissan Factory Key. Now this kit will fit many Nissan vehicles. Now the vehicles that this will work on, we do list them on the product page of this part number, or if you want, you can go to our fit guide on our website, put in your year and model of vehicle, and it'll show you which Nissans this will work on. Now this bolt coupler lock protects your trailer from tow away theft by preventing hookup to your trailer coupler.

And I did wanna pop up an insert just to show you what we're talking about. If you look, you can see this lock on a trailer coupler, so it prevents anybody from hooking up to their vehicle and towing your trailer away. This part will include everything laid out here on the table. It includes the plate itself, the shackle strap, the bolt lock and the pin, and then two different size balls with the bolt to attach the correct one to the plate. This will fit most latch style couplers.

Now the two included balls we talked about, it'll allow an application, the smaller one for a one and seven eight inch or a two inch coupler. If you use the larger one, it'll work for a two and five 16ths size coupler. Basically, the coupler ball socket will attach to the ball on the plate. So basically, once you install this one, we're gonna use the smaller ball here. And once you get that bolt tightened down and torqued into place, I happen to have, I pulled a two inch coupler.

So as we mentioned, the ball socket on the coupler is what'll attach to the ball here on the plate. So if you just open the latch, drop it on the ball, latch it, now it's hooked off to there. And then what you'll do is take this shackle strap, drop it into the back corset here, and drop it down as far as it'll go to where it lays on top of your latch so nobody can open the latch. Once those holes line up correctly, then you'll slide the pin through. That pin will go all the way through the shackle, and then you'll take your bolt lock and put it on the end there.

The shackle has six positions you can put it in. It's a steel collar to restrict coupler latch movement. And as we mentioned, the bolt lock itself will code to your vehicle's ignition key. So basically when you open this, you'll be able to put your ignition key in here and code it to where that will work in this lock to have your one key to work on your ignition. and even on the lock. It does use a six plate tumbler sidebar on the lock to prevent picking or bumping. Now, I did wanna show you also an insert. That's the type of key on the Nissans that this lock will work with. If your key looks like either one of those, it'll work with this lock. One thing I do wanna mention, that this bolt lock will permanently code to only one vehicle. They cannot be recoded or rekeyed. And you can see these parts do have a nice, bright red and black powder coat finish on them to resist corrosion. So if you need it to fit a larger two and five 16ths coupler, then all you have to do is switch out the ball, remove your bolt, put the large one on there, tighten it down, and it'll fit the larger couplers. But that should do it for the review on this Bolt Trailer and Coupler Lock for the Nissan Factory Key.

Glad you are liking it, Joshua! The BOLT locks definitely make these things a lot more convenient! ^___^ What kind of trailer are you using this on?

by:
It is made out of strong steel which would be difficult to cut through. While no product is 100% theft proof, this seems much better than average. I really like that it is keyed to my truck key. There are already too many keys for my trailer, so using a key I already have is convenient.

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.

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!

Works great with my 2026 GMC Sierra. I always have the key for the lock with me.
by:
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.

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 still like all of the Bolt products and am still using them. I would say that I do not recommend the Bolt padlocks as while they have the same great key setup I think the shackle is too long, too thin, and too exposed for easy removal by a small grinder or bolt cutter. Otherwise great stuff. I do wish they actually made a hockey puck style padlock instead

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

One key to rule them all, you might say? : P Glad to hear you are getting good use out of them, Eldon! Being able to use your vehicle's key for locking up any manner of things definitely makes life easier. What vehicle are you towing all your stuff with?

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.
by:
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.

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.

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.

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.

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!!

Took forever but given current international complications, it’s understandable . Thanks for your constant updates.

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.

Still very happy with my locks. This is the longest Ive gone without misplacing the keys, great being able to use the truck key for everything.

by:
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.

Still works great. I love not having to carry extra keys. I pull a trailer every day and it’s very convenient!!

by:
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.

Excellent product

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.

  • Trailer Coupler Lock That Codes to 2004 Nissan Titan Key
    There are two BOLT Trailer Coupler Locks that are compatible with the key on your 2004 Nissan Titan; you will only need to make sure it looks like one of the keys in the accompanying photo.
