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 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.

This heavy-duty padlock codes to your vehicle's ignition key. Made of automotive-grade materials and nearly impossible to pick or bump, this corrosion-resistant lock helps keep your trailer and equipment safe and secure.


Easy peasy. I’ve got a 2022 3500 HD Silverado with the key that pulls out of the remote. Stuck it in the locks, turned clockwise and done! I checked out these locks on Amazon and each part number said it wouldn’t fit my truck. I knew if I bought them from e-trailer and had a problem, I would get the customer service that I needed. The price difference was negligible ( Amazon was $2 more) and shipping was free over $100. No contest! Oh, I had emails through the whole process telling me where everything was at, and an email that said it was delivered! Can we say great customer service!


Convieant to have my truck key open lock. I have less keys to deal with.


Works with 2018 Chevy Silverado


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.


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!


Added security without additional keys.
Love it.


Nice quality locks and a breeze to set up. I can't believe no one thought to make these locks before now. I shall be ordering the pintle hitch lock next.

2019 GMC Sierra 2500

The information on the website was very precise. The locks arrived a day before they were scheduled and worked the way they were designed to work. I cannot say anything better about this order other than I am completely satisfied and will order from them again as needed.


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!!!


I am thrilled with the product strength, ease to set my key to the lock, and the fit to my 2015 truck tow hitch. Fantastic !

2021 GMC Sierra 3500

love the 1 key concept no pocket full of keys well made


Great lock. No more combinations to remember and I always have the keys on me.


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.




Excellent concept, and a great, solid product to accomplish it.

2018 GMC Sierra 2500

They just got delivered very fast. I want to try them out soon.



Great idea to minimize extra keys!


Easy to use no more having to deal with a bunch of keys


This is one of the best ideas yet!!! I love these locks!


Fast delivery

  • Does BOLT Padlock # BL7023537 Fit 2018 GMC Canyon
    For the GMC Canyons there can be two different key designs for the truck which is why there's an asterick. What you need to do is compare the picture I attached to the key you have, and if your key matches one of the three pictures the BOLT Covered Padlock part # BL7023537 that you referenced is a confirmed fit.

  • Sears X-Cargo Roof Carrier Latch and Lock Fit
    The top portion of your latch should be on the outside of your shell and not the inside. It looks like the parts were likely dismantled for cleaning or painting and were reinstalled incorrectly. We do offer some great BOLT Covered Padlocks like the # BL7023537 (GM Center Cut Key) which will key to your specific vehicle key. This will make it easier to always have the correct key and not having to worry about losing your other keys.

  • 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...
