Review: Nice and secure - 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.
Review: Best lock in the market. - 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.
