RETRUE Trailer Hitch Lock Set — Keyed Alike 3-Piece Kit, Black, Adjustable Coupler & Receiver Locks

RETRUE Keyed Alike Trailer Hitch Lock Set is a three-piece anti-theft kit that secures your trailer coupler, receiver, and latch-type tongue with matching keys for fast, reliable protection.

This compact kit groups the most common trailer locking points into a single solution: an adjustable coupler lock that fits 1-7/8", 2", and 2-5/16" couplers, two receiver-style hitch locks sized for 5/8" and 1/2" pins, and a tongue lock pin for latch-style couplers. Each lock is keyed alike so one set of four keys operates the entire kit, simplifying access while deterring theft with hardened materials and weather-resistant finishes.

How does the coupler lock adapt to different trailer ball sizes?

The coupler lock features an adjustable design with 11 locking positions to fit the most common coupler sizes without extra adapters. It clamps securely over the coupler mechanism and prevents the ball socket from mating with a hitch ball.

• Fits 1-7/8", 2", and 2-5/16" couplers
• 11-position adjustable locking for tight fit
• Aluminum body with A36 steel internal components for strength

What receiver pins are included, and how do they stop theft?

The kit includes two receiver-style hitch locks sized to cover common receiver pin diameters: a 5/8" pin with roughly 2.8" effective length and a 1/2" pin with about 2.2" effective length. These locks replace standard hitch pins and resist removal with cutters or pry tools, locking the accessory or ball mount to the receiver tube.

• 5/8" diameter pin — long enough for most ball mounts and accessories
• 1/2" diameter pin — fits slimmer applications and lightweight accessories
• High-strength steel pins and reinforced locking components for cut resistance

Will the tongue lock pin work with latch-style couplers?

Yes — the tongue lock pin is designed for latch-type couplers and fits openings up to 3/4" span. It blocks the latching mechanism so the coupler cannot be closed onto a hitch ball, providing a simple mechanical deterrent.

• 1/4" diameter tongue pin for latch-type couplers
• Accommodates latch spans up to 3/4"
• Black finish resists corrosion and hides wear from road use

How durable and weather-resistant are these locks?

RETRUE builds this set with an aluminum outer body and A36 high-strength steel internal parts to balance weight and toughness. The lock cylinders and thicker keys have been upgraded to resist picking and deformation, and the exterior surfaces are treated to withstand rust and road salts.

• Aluminum housing combined with A36 steel for cut and shear resistance
• Weatherproof finishes to reduce corrosion in wet conditions
• Upgraded lock cylinder and thicker keys for enhanced security

Who is this for? The RETRUE Keyed Alike Trailer Hitch Lock Set is aimed at trailer owners, contractors, and outdoor enthusiasts who want a single, practical kit to secure common hitch connection points. It suits those who tow seasonal gear, boats, landscaping equipment, or cargo and prefer one key for quick access. If you need a compact, weather-resistant locking solution that adapts to multiple coupler sizes and receiver types, this kit offers a balanced combination of convenience and mechanical protection, backed by a 120-day responsiveness policy for product-quality concerns.
