Best security lock made!

One of the most challenging locks for pickers. A real must for protecting valuables.

Consistently rated one of the best puck locks by lock pickers (do your own research). Company is very responsive if you need more locks with matching keys. I use these on all my trailers and storage units.

Outstanding Purchase and Delivery Experience!

I recently purchased 3 proven trailer locks and couldn't be more satisfied with both the product and the delivery process. The locks are solid, heavy-duty, and clearly built to last—exactly what I needed for added peace of mind.The delivery was prompt, with everything arriving securely packaged and in perfect condition. From start to finish, this was a smooth and professional experience. Highly recommend these trailer locks to anyone looking to upgrade their security. Well worth the investment!

Another well built lock from Proven Industries, remember it’s not to never have someone break in it but it is a great lock to prevent thief’s from stealing

These locks are awesome! I bought the wrong tongue lock and they resolved My mistake fast. Their customer service is top notch! Awesome product and awesome company!

Faulty locking mechanism.

The locking mechanism needs to be redesigned. For the price of these locks one would expect it to work every time. Every time I go to unlock I spend at least 5 minutes fiddling with the key in the lock until it aligns the pins and opens, the same thing happens when I try to lock them back on the trailer. I have decided that the hassle is not worth the money and ordered puck locks with a more traditional and proven locking system.
