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 like these locks that will work with my truck key. i like having one key that will work on my truck and these locks. very well made and heavy duty at that. 600842

- BL7018518

Not what I expect Insert my ignition key Follow the instructions and twist My key and almost broke it Need to replace the padlock Or may be the wrong model to fit a 2003 GMC 500635


Thanks for your product review, I did want to let you know that this Bolt lock BL7018518 is not a fit for a 2003 GMC, the earliest GMC year offering for this lock is a 2007. Which would explain the issue you had. For your 2003 GMC you would want the Bolt Lock BL7018517.

Ask the Experts about this Bolt Padlocks

Do you have a question about this Padlock?

  • Can BOLT Vehicle-Key-Specific Locks Be Programmed for 2 Different Keys
  • All of these BOLT locks, such as their Covered Padlock that codes to GM center cut keys, part # BL7023537, can be programmed with one and only one key. The one-time coding process requires simply that you insert the compatible vehicle key and turn it once. This results in permanent coding of that one lock to that one key. Once coded the locks cannot be re-coded for another vehicle key. All of the BOLT vehicle-specific locks that we offer can be seen on the link at right. These include...

  • Availability of Keyed Alike Coupler Lock, Hitch Lock and Padlock
  • Unfortunately, we can't get MasterLock products Like the # 377DAT keyed alike with different locks, but I might have an option to key everything else to your vehicle ignition key. BOLT offers hitch locks, coupler latch locks and padlocks that can be keyed alike to certain vehicle ignition keys. For instance, if you had a 2013 Chevy Silverado, you could use the BOLT # BL7018446 hitch lock, the # BL7018518 padlock or even the # BL5922987 locking tailgate handle. I don't have anything...

  • Locking Tailgate Handle for 2004 Chevy Avalanche
  • Unfortunately, according to my contacts at Pilot, the Integrated OEM Tailgate Lock, part # LH-003 will not fit a 2004 Chevy Avalanche. However, we do have an available solution for you. BOLT offers the # BL5922987 that has a lock cylinder that you permanently 'code' to your ignition key. You'll install the locking handle, insert your ignition key, turn the key once and the lock will be keyed to match your ignition key. Pretty cool stuff! BOLT also offers other locks that can be keyed...
