BOLT Receiver Lock for 2"–2.5" Hitches — 5/8" Stainless Pin, Works with Chevy/GMC/Buick/Cadillac Center-Cut Key

The BOLT 7023582 5/8" Receiver Lock secures your 2"–2.5" trailer receiver using your vehicle's center-cut Chevy/GMC/Buick/Cadillac ignition key.

Keep your hitch and trailer accessories protected without adding another key to your ring. The BOLT receiver lock replaces separate hitch keys by matching the lock cylinder to your vehicle ignition key, simplifying access while delivering heavy-duty theft resistance for Class 3–5 towing setups. Built with a solid stainless-steel pin, a weather-resistant jacket, and an automotive-grade lock cylinder, this model focuses on durability, ease of use, and long-term reliability.

How does this lock eliminate extra keys and simplify towing?

Instead of carrying a dedicated hitch key, the BOLT lock is coded to work with your vehicle’s center-cut ignition key. That means the same key that starts your truck also opens the hitch, reducing lost-key risk and streamlining your routine when hooking up a trailer.

• Pairs with Chevy, GMC, Buick, and Cadillac center-cut ignition keys
• No separate hitch key to store or misplace
• Auto-return spring automatically locks when the key is removed

Will this fit my hitch and handle heavy towing demands?

The 5/8" stainless-steel pin is engineered for class 3, 4, and 5 hitch receivers (commonly 2"–2.5" openings), making it appropriate for most medium- and heavy-duty towing applications. Its robust construction resists bending and tampering under typical towing loads when used as a receiver lock.

• 5/8" diameter solid stainless steel pin for strength
• Designed for 2"–2.5" (Class 3–5) receiver tubes
• Weather-resistant jacket protects the pin and receiver from corrosion

How secure and weatherproof is the locking mechanism?

The cylinder is built to automotive standards and includes multiple anti-tamper features to resist common attack methods. A stainless-steel shutter helps keep dirt and moisture out, and internal mechanisms are chosen for durability and pick resistance—ideal for outdoor, long-term exposure.

• Automotive-grade lock cylinder matched to vehicle ignition key
• Stainless-steel lock shutter keeps contaminants away from tumblers
• Plate tumbler sidebar and double ball-bearing locking mechanism resist picking and pulling

What convenience and protection features does the BOLT receiver lock include?

Beyond key consolidation and mechanical strength, this lock adds user-friendly touches that reduce hassles and extend service life. Its auto-locking behavior and protective jacket make it a low-maintenance solution for frequent towing or long-term storage.

• Auto-return spring locks automatically when key is removed for quick security
• Weather-resistant jacket prolongs finish and reduces corrosion
• Limited lifetime warranty provides added ownership confidence

Who is this for? The BOLT 7023582 is aimed at truck and SUV owners who tow regularly with Chevy, GMC, Buick, or Cadillac vehicles and want one-key convenience paired with a rugged, weatherproof receiver lock. It's a practical choice for contractors, weekend RVers, boat owners, and anyone who wants to secure a Class 3–5 hitch without managing extra keys. If you use a 2" or 2.5" receiver and prefer automotive-grade security that integrates with your vehicle key, this lock delivers a durable, low-fuss solution.
