BOLT 5/8" Receiver Hitch Lock for Chevrolet GMC Buick Cadillac - Center-Cut Key, Stainless Pin, Weather-Resistant

The BOLT 7023582 5/8" Receiver Lock secures Class 3–5 trailer hitches and opens with your vehicle's center-cut ignition key so you never need an extra lock key.

This heavy-duty receiver hitch lock is built to pair with center-cut keys used by Chevrolet, GMC, Buick and Cadillac, letting you use the same key already on your ignition. Designed for 2" to 2.5" receivers, the 5/8" stainless steel pin and weather-resistant casing are made specifically for larger towing setups. BOLT integrated their patented One-Key concept and automotive-grade locking components so the hitch stays locked, resists tampering, and keeps contaminants out.

How does this lock fit my truck and trailer setup?

This model uses a 5/8" diameter stainless steel pin intended for Class 3, 4, and 5 applications. It fits standard 2" and 2.5" receiver tubes and installs just like a conventional receiver pin, but with an internal lock cylinder that matches your vehicle key.

• 5/8" solid stainless steel pin for higher towing capacities
• Compatible with 2" and 2.5" receiver openings
• Works with center-cut Chevy, GMC, Buick, and Cadillac ignition keys

What security features protect against theft and the elements?

The lock combines a plated-tumbler sidebar and double ball-bearing mechanism to resist picking and forced entry. A stainless steel shutter and a weather-resistant outer jacket guard the cylinder from dirt, moisture, and road grime so the lock remains operational in harsh conditions.

• Plate tumbler sidebar reduces susceptibility to picking and bumping
• Double ball-bearing locking prevents the pin from being pulled out if attacked
• Stainless steel shutter and weather jacket block moisture and debris

How easy is it to use day to day?

The BOLT Receiver Lock is designed for simple, no-fuss operation: insert the pin, turn your vehicle key, and the auto-return spring locks the pin the moment you remove the key. Because it uses your ignition key, you avoid carrying extra keys for your hitch — convenient for frequent haulers and occasional users alike.

• Opens and locks with your vehicle ignition key for single-key convenience
• Auto-return spring enables automatic locking when key is removed
• Quick install and removal with no additional tools required

What durability and warranty can I expect?

Materials and internal components are selected for long-term toughness: a solid stainless pin resists bending and corrosion, and the lock cylinder uses automotive-grade parts. BOLT supports the product with a limited lifetime warranty for peace of mind.

• Solid stainless steel pin and corrosion-resistant finish
• Automotive-grade lock cylinder for reliable repeated use
• Limited lifetime warranty from BOLT

Who is this for: The BOLT 7023582 5/8" Receiver Lock is ideal for owners of Chevrolet, GMC, Buick or Cadillac trucks and SUVs who tow heavier loads and want a secure, weatherproof hitch lock that uses their existing ignition key. Choose this lock if you need a robust pin for Class 3–5 towing, want protection against theft and the elements, and prefer the convenience of a single key for vehicle and hitch security.
