Hitch locks are pin latches designed to keep your ball mount attached to your vehicle. This will prevent it from being stolen while your vehicle is parked but disconnected from your trailer. However, it’s important to also note that ball mounts should not always remain attached to the hitch; this can make your accessories corrode faster by suffering unnecessary wear and exposure to the elements. Between trips and uses, you should always detach, clean and safely store your ball mount.
Trailer locks cover your trailer’s latching mechanism so that no one can hook their car, truck or SUV up to your trailer when it’s not directly secured to your own vehicle. These typically lock a metal ball in place, similar to how your trailer is traditionally rigged.
Coupler locks also use pins, but these secure your trailer’s latching mechanism to the ball mounts while you’re on the go. Coupler locks offer a variety of drop lengths, ball widths and all trailer weights and sizes. They’re not only made to be secure and easy-impact on the road, but they’re also weather-resistant metal alloy that will prevent or resist rust and corrosions when sitting in the elements for great lengths of time. These anti-theft devices are designed to be resistant to picks and drills so that no one can detach your trailer without your key.
If you have several trailers, you can have all of your locks prepared so that they all work with a universal key, which helps you stay organized and prevents key-switch mishaps. If you only plan to use one trailer at a time and want one kind of lock (hitch, trailer or coupler) for all of your vehicles, you can purchase a universal lock that can adjust to work with all truck and trailer types.
