Trailer Hitch Locks and Locking Pins Explained
Updated 2026-10-20 · Rhino Hitch Inc · Facts checked 2026-10-20
Quick answer
A trailer hitch lock replaces the standard receiver pin so the hitch can't be removed without a key. Rhino Hitch sells InfiniteRule stainless steel security locks matched to each hitch rating, plus replacement adjustment pins.
An adjustable hitch has two kinds of pins, and both matter.
Receiver pin or lock
This pin goes through your vehicle's receiver and the hitch shank. A locking version needs a key to remove, which deters theft of the hitch.
Adjustment pins
These hold the ball mount at the drop you chose. They carry towing loads, so use pins made for your hitch.
