  • Great, low cost trailer lock if you're in a pinch
Style: Coupler Lock
We were renting a uHaul for a week trip and I wanted to secure the trailer so I could disconnect and leave while we were out and about. This was a low cost, great solution. Gave me peace of mind that it would deter theft and was easy to use. Only potential issue is you can tell it is low cost, the keys are kinda like the daughters first diary level quality (not robust) and I'm not sure I'd trust it to stay outdoors in the elements long term as it'd probably rust. Overall: This is great for occasional use but I'd personally upgrade to something better if I was using it on my own trailer long term. ... show more

  • Purchased for another use.
Style: Coupler Lock
Though I do pull a trailer, I purchased this for another use. I use it to lock down a large trashcan lid. works like a charm.

  • Good for the cost
Style: Coupler Lock
Can be hard to unlock as key mut be inserted perfectly, cannot remove key from cylinder until you relocked it

  • Good quality lock
Style: Coupler Lock
It’s a good lock, a little hard to lock until you use a time or two. Gives you piece of mind when leaving a trailer unattended, but it could probably be broken off with a hammer if they are serious about it…

  • Great long lasting lock.
Style: Coupler Lock
Had to order a 2nd one only because I left my last one on the rear bumper and dropped off somewhere. Got the same one because my last one was over 3 yrs old and never had a problem with it. Even in subzero temps with ice and snow it never seized up. Well worth the money.

  • Theft deterrent NOT theft proof
Style: Coupler Lock
The steel pin and the cylinder lock are not substantial to stop theft. But provides theft deterrence from crimes of opportunity, e.g. thief needs to have tools handy to easily defeat this lock. I Use this trailer coupler latch lock to secure my empty boat trailer to my tow vehicle in the marina boat ramp parking lot only. ... show more
