Trailer Hitch Locks

Take security a step further with a trailer hitch lock. Like a pin and clip, our hitch locks insert into the fastener hole in the side of a receiver tube and hold a ball mount or other hitch-mounted accessory in place. Shop our standard sizes in a variety of styles to perfectly suit your vehicle-trailer setup.

Lock Your Hitch with Confidence

We have the trailer hitch and coupler locks you need to keep your trailer secure. Take security a step further with a trailer hitch lock or coupler lock that is designed to keep your hitch-mounted accessory in place and prevent theft of your trailer. Shop our standard sizes in a variety of styles to perfectly suit your vehicle-trailer setup.

Hitch locks are important for trailer security. Like a hitch pin, a hitch lock is designed to insert into the fastener hole in the side of a receiver to hold a ball mount or hitch accessory in place. We offer barbell, dead-bolt and right-angle-style hitch locks in 1/4", 1/2" and 5/8" pin sizes for all standard receivers.  

We also offer padlock and barbell-style coupler locks, featuring 1/4-turn lock activation and hardened steel locking pins for reliable security and easy operation. Made with a 1/4" locking pin and available in brass, stainless steel and black finishes to complement your trailer.

Sometimes a safety pin and coupler latch aren't enough to keep your trailer secure. The CURT universal trailer coupler offers premier security, prevents a trailer ball from being inserted into the coupler and fits most ball receivers.
