Trailer Hitch Locks & Coupler Locks

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 hitch locks are available to fit any industry-standard receiver tube size, and they are available in various styles and finish options to give you a lock that suits your towing setup.

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!

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.

CURT specialty towing locks include everything from wheel chock locks to spare tire locks. These tow locks are intended to help you further secure your vehicle and trailer, beyond just a standard hitch lock and coupler lock.

Right-angle

Right-angle hitch and coupler locks provide ergonomic access to the keyhole. Instead of straining to reach the keyhole from the side, the perpendicular head swivels to always point in the right direction.

Barbell

The barbell is the traditional style for hitch locks. The design is compact, subtle and effective. One end of the lock is a knob to secure the pin, while the other is a key-operated removable cap.

Deadbolt

The deadbolt hitch lock is another traditional style. This type of lock has a hitch pin with a bent handle on one end. The other end of the pin inserts into a deadbolt cylinder or square to secure the shank.

Adapter

Hitch locks with an adapter sleeve enable use with different receiver sizes. Standard receiver pin holes are 1/2” or 5/8”. A 1/2” lock with a 5/8” sleeve equips the lock to fit various hitch classes.

Segmented

This type of trailer coupler lock has a pin with multiple segments, allowing the lock cylinder to be incrementally adjusted. The lock can be secured at each segment to fit a range of coupler spans.

Over-lip

The over-lip coupler lock slides over the trailer tongue opening, blocking a ball from being inserted. This type of lock is great for adding security to a parked trailer. It cannot be used for towing.

Shackle

A shackle trailer lock is similar to an over-lip coupler lock, engaging the trailer tongue opening to prevent a ball from being inserted. A metal shackle then secures over the top of the coupler.

Padlock

A coupler padlock is a compact style of trailer lock with a short pin, offering subtle, low-profile trailer security. A trailer padlock can be used to keep the coupler latch engaged or disengaged.

Anti-rattle

An anti-rattle hitch lock combines the security of a trailer hitch lock with the sound-dampening functionality of an anti-rattle kit. An anti-rattle lock deters theft as well as vibrations.

Right-angle

Right-angle hitch and coupler locks provide easier, ergonomic access to the keyhole. Instead of straining to reach the keyhole from the side, the perpendicular head swivels to always point in the right direction.
