CZC AUTO Hitch Receiver Pin Lock Keyed-Alike 2-Pack 5/8" Pin Weatherproof for 2" & 2-1/2" Receivers

The CZC AUTO hitch receiver pin lock is a keyed-alike, 5/8" pin security set designed to secure 2" and 2-1/2" Class III/IV receivers for trailers, bike racks, cargo trays and towing accessories.

If you tow equipment, haul racks or leave gear on a hitch-mounted carrier, a robust pin lock stops casual theft and prevents parts from dislodging while driving. This two-pack includes two identical-key locks (four keys total) built to fit common 2" and 2-1/2" receiver tubes, with a 3-1/2" effective pin length and weatherproof features for outdoor use.

How does this lock fit different receiver sizes?

The CZC AUTO receiver pin lock is designed for both 2" and 2-1/2" hitch tubes used on Class III and IV systems. Its 5/8" diameter pin slides through the hitch and accessory mount, and the 3-1/2" effective length accommodates most standard setups without adapters.

• 5/8" solid carbon-steel pin resists bending under normal loads.
• 3-1/2" effective length fits common receiver offsets and shanks.
• Compatible with bike racks, cargo trays, hitch balls and tow ropes.

What materials and weather protection does it offer?

This lock combines a painted carbon-steel shaft with a zinc-alloy lock core and a rotating head for ease of use. An electrophoretic black coating and rubber key cap help keep moisture and road salt away from the mechanism to reduce corrosion over time.

• Electrophoretic paint finish resists chipping and rust.
• Zinc alloy lock core for stable key action.
• Rubber keyhole cap shields from water and dust.

How easy is it to operate and manage keys?

Each set comes keyed alike so both locks open with the same keys, simplifying access when you use multiple hitches or accessories. You receive two locks plus two keys per lock (four keys total), and a simple pull test after locking confirms the head is secure.

• Keyed-alike convenience—one key opens both locks.
• Two keys per lock included, four keys total in the pack.
• Quick pull test verifies correct engagement after locking.

What warranty and support are included?

CZC AUTO includes a 30-day return window and a 12-month warranty for quality-related issues, with customer service available for any concerns. If you encounter defects or fitment problems, contact support for replacement or refund assistance.

• 30-day money-back option for any reason.
• 12-month warranty covering manufacturing faults.
• Customer support available for fit or function questions.

Who is this product for? This two-pack is aimed at drivers, RV owners, and cyclists who use hitch-mounted accessories and want a straightforward way to secure them. It suits people who need a durable, weather-resistant pin lock that fits common 2" and 2-1/2" receivers and prefer the convenience of keyed-alike operation for multiple locks.
