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.

Video Transcript for BOLT Product Line Review

Today, we're going to be taking a look at the BOLT family of locks. Now, the BOLT is a very unique lock. It's designed to use your vehicle's ignition key and it can be coded to Toyotas, Nissans, Fords, GM, Chevys. A lot of different vehicles. The BOLT lock, the BOLT, BOLT, stands for Breakthrough One Key Lock Technology. As you can see here, we've got a padlock on. Our padlock.

It uses our factory Ford key. No extra keys that we have to keep up with. As you can see, it opens it nicely, locks without a problem. The special part is that now we can take this same key right over to our six-foot-long self-coiling cable lock. Operates it just like it did the padlock. If you'll come here to the hitch with me, take a look.

We've got our trailer coupler lock right here. Same key. Operates that without issue and even down here to our hitch pin lock. We're looking at the same thing. Key is going to go right in.

Functions just as it should, all using that exact same key. Now, they even have pickup truck bed mountain toolboxes. They've got the latch style levers on them. They've got the BOLT One Key accessories to fit that and even spare tire carriers. I've got that installed on my Jeep, so let's take a look at that one. As you can see here, on our Jeep, the same technology applies. All of them have the nice rubber hardened protection that's going to go around the lock.

They've got a stainless steel lock shutter that's going to protect our zinc cast core from any kind of corrosion, giving us some really superior corrosion resistance. Got that and it's going to go right over the top and cover that up as well. They use a six plate tumbler style. It is an automotive quality lock. That's going to prevent any kind of picking or anything like that. Now that we've gone over our full line of the BOLT locks, that will complete today's look. .

I absolutely love these locks!! I've had them for my last truck and just recently bought a whole new complete kit for my new truck and trailers. IMO the greatest thing invented to make trailer and travel life easier... Don't be afraid of the price- they're well worth it! You'll see!!! 583261

Product shipped and received in time frame promised. Easy to program however a little difficult to lock after programming. Over all good product just the problem of getting to lock easily kept me from giving it 5 stars. 567862

Carrying a handful of keys for your trailer is a pita... One year later, I'm still loving these locks... Not only am I down to one key for the trailer, but one key for everything! I'd never buy another lock except for a bolt. A lil more money but worth every penny in the hassle it saved! 546789

Bolt fanboy bias. User of the Bolt receiver and hitch coupler lock. Relatively expensive padlock. Price for the convenience of single key operation for all the locking mechanisms used on the truck and trailers. The lock seems to be a solid design. Both shackle arms lock into place. Firm connection. The indents in the shackle arms are ~1/4” below the top surface of the lock body when locked. Length of shackle is imho a good compromise. Full 1.5” x 1” space within the widest points of the shackle. Gated key slot to reduce dust and moisture entry. Look at all locks as preventive. Reduce the temptation of those with sticky fingers. More as a deterrents to thieves. A serious semi-intellegent low life will not be stopped by any lock. Bolt meets the need with the convenience of single key use. 492781
