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

### ⭐⭐⭐⭐⭐ Four years in and still going strong — peace of mind for my tiny house trailer
*by J***D on 19 June 2026*

I've been using this lock on my tiny house trailer for over four years now and it has been completely reliable. No issues with the mechanism, no rust problems, no signs of wear that would make me question it. It just does its job every time. For anyone securing a tiny house or a heavy trailer, the fact that it fits the 2 5/16-inch coupler and also secures the safety chains is a big deal — it's not just stopping someone from hitching up and driving off, it's locking down the whole connection point. Who this is for: Anyone with a 2 5/16-inch coupler trailer who wants a serious lock they can trust long term. Tiny house owners especially — this is exactly the kind of thing worth spending money on rather than cutting corners. Any downsides? None that I've encountered after four years of use. That's really all that needs to be said.
