TOPICK Trailer Coupler Lock Set Keyed Alike — Ball & U-Shaped Latch Locks, Fits 1-7/8"–2-5/16", Corrosion-Resistant

TOPICK Keyed Alike Trailer Coupler Lock Set secures your trailer hitch and latch with two matched locks that use the same key for fast, reliable protection.

Protecting a trailer, boat, RV, or utility trailer starts at the coupler. This kit combines a heavy-duty trailer coupler ball lock and a 1/4" dia U-shaped coupler latch lock, engineered to fit a wide range of hitch sizes while resisting corrosion and tampering. Built from reinforced steel with weatherproof finishes and rubber caps, both locks are designed for frequent outdoor use and simple everyday handling.

Will this lock pair fit my trailer hitch?

The TOPICK set is designed for broad compatibility with the most common coupler diameters, so it works across many trailers without extra adapters. It fits 1-7/8", 2", and 2-5/16" couplers and secures the latch and ball area to deter theft or unauthorized towing.

• Includes trailer coupler ball lock plus 1/4" diameter U-shaped latch lock
• Compatible with 1-7/8", 2", 2-5/16" coupler sizes
• Adjusts to most RVs, boats, utility and cargo trailers

How durable is the construction against weather and wear?

Both pieces in the set are built from high-strength steel and treated with protective coatings to stand up to rain, salt air, and road grime. A PVC-coated U-bolt prevents scratching and adds grip, while electrophoretic paint and zinc plating reduce rusting for long service life.

• PVC-coated U-shaped bolt for scratch resistance and better handling
• Electrophoretic paint and zinc plating for corrosion protection
• Rubber caps shield lock cylinders from dirt and moisture

How secure are the locks against picking or forced entry?

The locking cylinder employs a more intricate internal mechanism and reinforced key design to make picking and forced manipulation more difficult. Coupled security—blocking both the ball and the latch—adds a physical barrier that slows down opportunistic tampering and towing attempts.

• Complex cylinder structure and reinforced keys for enhanced anti-tamper resistance
• Two-lock system protects both hitch engagement points
• Included rubber caps and solid materials reduce exposure to prying tools

What convenience features does this keyed-alike kit offer?

No need to carry separate keys for each lock: the set ships keyed alike, so a single key operates both units. The package contains four identical keys so owners have spares for drivers or storage in case of loss.

• All locks keyed alike for single-key access
• Four keys included—extra on hand for backup
• Compact shapes and rubber grips make handling quick and simple

Who is this for: The TOPICK Keyed Alike Trailer Coupler Lock Set is aimed at trailer owners who want a straightforward, robust deterrent to theft and unauthorized towing. It suits RV owners, boaters, landscapers, utility and cargo trailer users, and anyone who parks or stores trailers outdoors and needs a weather-resistant, easy-to-use security solution that covers both the coupler ball and the latch.
