Secure, but terrible lock mechanism that freezes

7 months ago
Lock fits easily enough with my camper and snowmobile trailers, but the keyed lock mechanism is rough at best under ideal conditions. In the winter, it constantly jams/freezes up and will not unlock until I heat it with a blowtorch for a few minutes. Just an absolutely terrible locking mechanism that is a hassle to use. Avoid if you plan to use on any trailers below freezing temperatures. I will try a lock with a regular key next to see if that's any better.

No, I do not recommend this product.
