BOLT Locks for Convenience and Security

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 for Commercial Applications

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.

The pin would not fit in the lock. I had to grind it down slightly. Once that was done works great.

I reached out to the manufacturer and there was a small batch that were made that did have a larger pin head. It has since then been corrected and I also had our stock checked as well. The manufacturer will reach out to you.

I bought three Bolt Trailer Hitch Receiver Locks. I absolutely love them. You can't beat the convenience of using your ignition key as the same key to unlock the Bolt lock. It is a two for one deal. Now all three of our hitches are safe, secure and convenient to use. Etrailer website was very easy to use. I was unable to find two of our vehicles receiver locks elsewhere, Etrailer had them. Super fast delivery. If you need a Trailer Hitch Receiver Lock, Bolt is the way to go and ETrailer is the place to buy it!

2017 GMC Sierra 2500

One of the coolest towing accessories I've purchased in a long time. I'm still amazed the lock fits the factory vehicle key. No more looking for lost keys and having to cut the old receiver lock off.


Nice to have my tow vehicle keys open the hitch lock. I have less keys to keep up with.


Great selection of products with competitive pricing. Shipping time is incredibly quick. Customer support and communications are 5 star. I will continue to purchase all of my trailer and towing components with this company. Years of rock solid support and selection will keep me returning to this trusted supplier. Thank you

Chevrolet Colorado

I was very impressed with the items I ordered. Brent told me about the lock that I could get that work with my ignition key and it is great. the receiver hitch looks very nice on my Chevy Colorado and really dresses up the back of truck.


Never fails. Awesome product. One less key or combination to worry about :)


Works great! Actually need another one since I got a new truck!

2018 GMC Sierra 3500

Good quality,nice being able to use your vehicle key to key the lock the same. Probably one of the best items that I have purchased for my hitch assembly.

2016 Chevrolet Silverado 3500

So much simpler to just have have the truck key and be able unlock the pin. As others have mentioned the lock is very big and you may have trouble hooking up your safety chains. You may find if you remove the lock and then hook up you chain, it may make it easier. Just don't forget to put the lock back on. I just wish they made a coupler lock now.

Thanks for your review, Bob. I have good news! The coupler locks may be found at the following link:

Ram 2500

Great product fast shipment , works very well on my 2500 GMC 2022.


What a great lock! We have used one for years on our receiver hitch. It works perfectly for our king pin too!


The service was great. The product was delivered quickly with much detail if the progress!

2015 GMC Sierra 2500

What a slick setup. Lock and pin all in a line and rubber cover over keyhole. Since it uses my Toyota tailgate key it is easier than fumbling for yet another key to get ready to hook up a trailer.

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

Ordered 2 for my GM trucks. Excellent product. Only complaint is that I have to turn truck off to use truck key to unlock and flip my B&W hitches. Best thing, can’t lose a hitch lock key unless you lose your truck key. Just ordered another for another truck.


Nice deal. Should work great!!


For those with a 2021 GM key that embeds into the fob… it works with this product!


Works great and very convenient!


Great idea for keyed lock same as towing vehicle
No more looking for keys
Great company to work with

2018 Chevrolet Silverado 2500

Vehicle ignition key also operates the hitch lock. AMAZING!!
Simple to use. Great very well thought out construction.

GREAT!! 1 year later and still works like new. You must get one.
Eddy - 08/31/2019


Easy to set. Well made. Are sealed well. Come greased. Just spread it around after you first insert the shank. Really nice to only have to pack around one key.
Also. Although these cant be rekeyed. If you buy a new vehicle, you can contact bolt and they will send you a coupon for a discount on new locks


The convenience of using the existing vehicle key is a game changer. Easy on easy off. Key not required to put it on like other receiver locks I have had in the past.


Love it. Eliminates the need for a separate key. Works off the my truck ignition key.


I was a little concerned that this receiver lock was to be coded to just my one truck. Because I have a newer truck and expect I will have it for some time I went ahead and ordered. The bolt is plenty long for my 2.5 in hitch. Programming the lock to my truck key was very simple. It is in place and protecting my heavy duty 6 inch drop hitch also purchased a few months ago from ETrailer. Why not five starts? It should be able to be reprogrammed to other keys.

2018 Chevrolet Silverado

I bought this as a replacement after buying a new truck.
I forgot to make a copy of my old trucks key to use the one I had.
This is a great product and I love how you can set it to your vehicle key.
I bought this for a 2018 Chevy Silverado 1500. Some sights say this particular one wont work but they are wrong.
Thank you etrailer for another (3rd time buying from them) great purchasing experience.
