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.

Lock high quality. Fit my 2016 GMC sierra key, worked as advertised. customer service and follow up exceptional!!! econ shipping only took one day. Highly recommend etrailer. Thank you 339966

- BL7023582

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 737105

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. 617789

Vehicle ignition key also operates the hitch lock. AMAZING!! Simple to use. Great very well thought out construction. 560210

GREAT!! 1 year later and still works like new. You must get one.

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! 588604

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. 510695

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

Coolest lock ever! 882735

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. 870004

Works great 653869

- BL7023582

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. 646663

- BL7023582

Works great. Very easy to use with your factory key. 629405

- BL7023582

This is an excellent product and the added convienence of not needing a separate key and being able to use ignition key is great. The shipping was only two days which was far quicker than I imagined. Look forward to dealing with you again. 605615
