Hitch locks for your receiver

CURT hitch locks secure your hitch receiver, locking the inserted shank in place. The shank could belong to a ball mount, pintle hitch, cargo carrier or other hitch accessory.

CURT Trailer Coupler LockCURT Trailer Coupler Lock

Coupler locks for your trailer latch

CURT trailer latch coupler locks feature a locking pin that passes through the coupler latch, disabling it from being engaged or disengaged from a hitch ball. This is useful for adding security, whether the trailer is hooked up to the vehicle or parked by itself.

CURT coupler locks come in different styles and finishes. They can be used as a boat trailer lock, utility trailer lock, trailer trailer hitch lock and more!

Trailer locks for your trailer tongue

Similar to our latch-style coupler locks, CURT trailer locks engage the trailer tongue to prevent it from engaging with a trailer ball. Trailer locks are different, however, in that they are only meant for a trailer that is left parked and unattended. A trailer lock cannot be used when the trailer is hitched up to the vehicle.

Trailer locks are available in multiple styles, including over-lip style and a shackle style. They work well as a boat hitch lock, travel trailer lock and more.
