For years I have purchased middle of the road coupler locks for my trailers and every one of them, from Trimax, to Reese, to Master Lock has failed me in some way. Several of them had to have the lock cylinder drilled out because they were stuck on there and no longer worked with the key. I got sick of dealing with the headache of trying to leave on a trip and drilling out the lock to get my own trailer hooked up. I decided to spring for an expensive setup, hoping it would be my last. I will never again hassle with cheap locks.

This Proven Lock product is extremely well-made and heavy duty. It fit right onto the coupler of my trailer perfectly, holding the safety chain hooks inside and lining up the first time I put it on. The puck lock is very nice. The blue looks nice, and the lock cylinder seems like it will hold up. It is very easy to install and remove, and I am no longer worried about getting locked out from towing my own trailer again. Worth the money (albeit pricey) to save me some headaches.

This is my second unit purchased. I want to take a moment to share my positive feedback regarding the trailer tongue lock. This product has proven to be exceptionally reliable and secure, providing me with peace of mind whenever my trailer is parked. The robust design ensures that it effectively protects against theft, which is a significant concern for anyone who owns a trailer. I’ve also found it to be remarkably easy to install and remove, making it a practical solution for everyday use. The sleek design complements the overall look of my trailer, and the durable materials suggest that it will stand the test of time, even with regular exposure to the elements. Overall, I highly recommend the trailer tongue lock to anyone looking to enhance their trailer's security. It truly is an excellent investment for protecting your valuable assets.

Great quality lock. Very solid and well constructed. Delivered on-time.

I was also very impressed with their customer support and how fast they were able to resolve MY mistake when I ordered the wrong size for my hitch… I will be ordering more locks for my other trailers in the near future.

I have found Proven locks to be the best on the market. Quality is top notch and my hitch pin locks and Trailer Coupler lock have been working great. I definitely have better peace of mind when leaving my trailer unhitched with the Proven Trailer Lock guarding my little silver home :)

I recently purchased the Proven Industries Model 2516 Trailer Lock, and I must say it has exceeded my expectations in terms of security and durability. As someone who values the safety of my belongings, especially when it comes to my trailer, finding a reliable lock was paramount, and the Model 2516 did not disappoint.

The first thing that caught my attention was the build quality. This lock is constructed with hardened steel, making it incredibly resistant to tampering or brute force attacks. The robust design instills confidence that my trailer is well-protected against theft. The heavy-duty construction also gives it a substantial feel, reinforcing its reliability.

Installation was a breeze, thanks to the user-friendly design and clear instructions provided by Proven Industries. The lock fits seamlessly onto my trailer hitch, and the precision engineering ensures a snug and secure fit. The lock even allows for safety chains to be locked inside the case. Once in place, it's evident that this lock is not going anywhere – a vital aspect for those of us who leave trailers unattended for extended periods.

One of the standout features of the Model 2516 is its drill-resistant lock cylinder. This adds an extra layer of security, deterring potential thieves who might attempt to compromise the lock with conventional tools. It's reassuring to know that Proven Industries has taken measures to protect against various methods of tampering. Proven Industries' customer service was able to hook me up with a lock cylinder that is keyed the same as the other four Proven puck-locks that I purchased for my trailer.

I look forward to Proven's claim of the lock's resistance to the elements. Living in an area with diverse weather conditions, I needed a lock that can withstand rain, snow, and UV exposure. The Model 2516's corrosion-resistant materials ensure it remains in optimal condition, providing long-lasting protection for my trailer.

In conclusion, the Proven Industries Model 2516 Trailer Lock is a top-notch investment for anyone serious about safeguarding their trailer. Its robust construction, drill-resistant lock cylinder, and weather-resistant features make it a reliable and durable choice. While it may come at a slightly higher price point than some alternatives, the peace of mind and security it provides are well worth the investment. I highly recommend the Proven Industries Model 2516 to fellow trailer owners who prioritize the safety of their valuable assets.

Love the lock help keep my trailer safe for my sanity sake😄😄😄 great purchase definitely would recommend if own a trailer or anything u need good tough lock on

👌.

Great construction but the fit and finish was a little disappointing. I had difficulty getting the tabs to align with the coupler lock completely closed. If you opened it a little bit you could wiggle the puck lock enough to get to lock. As for the finish, the powder coat seem to be a little on the thin side. After trying to get the lock to fit, I found that I had lost some powder coat in lot of the contact areas. All in all. I still like the lock.

Solid design and great customer service!!!

Product is solid and works flawlessly --- very easy to use. Construction is top notch -- very solid. After placing order, the company reached out to me to just confirm that I had ordered to correct lock; requesting hitch photos if possible. I had in fact ordered the incorrect part, and this was all sorted before the lock assembly shipped. Overall outstanding customer service! Do not hesitate to do business with them through Amazon.

Great fit. Good deterrent. Suggest changing out the lock.

I ordered the incorrect lock for my Airstream. Proven technology exchanged the lock for the correct one at no charge. The lock is very heavy duty. I recommend this vendor and their product.

I have just received my Proven Industries 2516 Trailer Lock. The unit appears very well built, simple install and have had great customer support that was both very helpful and quick responses. This product gives us peace of mind when our trailer is not hitched to our truck.

Responsive customer service team. They helped me to correct my order quickly. Friendly and efficient. Once I receive my order I will share a review of the product. So far, all good!
