METOWARE Keyed-Alike Trailer Coupler Lock Set — Heavy-Duty 4-Piece Kit, Weather-Resistant Security for Ball Couplers & Hitch Pins

METOWARE Keyed Alike Trailer Coupler Lock Set is a four-piece, heavy-duty towing security kit that locks couplers, hitch pins and latch mechanisms so your trailer, RV or cargo stays put.

When you need a single key to control multiple trailer security points, this METOWARE keyed-alike set delivers a practical, weather-resistant solution. The kit combines an adjustable universal coupler lock with two bent-pin hitch locks and an adaptable latch lock, all using the same key. Each component is built for rugged outdoor use and designed to fit common coupler sizes and receiver classes, making it a versatile choice for boat trailers, utility trailers, campers and hitch-mounted accessories.

How does this set secure different trailer connection points?

The kit covers the main theft or accidental-disconnection risks by protecting the ball coupler, the hitch pin in the receiver, and the coupler latch itself. Each lock targets a different vulnerability and together they create layered protection for towing setups.

• Universal coupler lock: ratcheting, adjustable for various ball sizes and coupler depths.
• Bent-pin hitch locks: two diameters (1/2" and 5/8") to suit multiple receiver classes.
• Adjustable latch lock: spans and pins to prevent the latch from opening while driving.

Which couplers and receivers will fit this kit?

METOWARE designed the components to match standard towing hardware so you can use the set across a wide range of trailers and towing accessories. The adjustable features let you dial in a snug fit without additional tools.

• Universal lock adapts to common 1-7/8", 2" and 2-5/16" ball couplers across 11 indexed positions.
• 1/2" bent-pin fits most Class I and II receivers and smaller accessory mounts.
• 5/8" bent-pin fits Class III–V receivers, bike racks, cargo carriers and ball mounts.
• Latch lock adjusts from about 1" to 3" span to secure various latch widths.

What materials and anti-theft features protect the locks outdoors?

The locks use durable metals and an upgraded lock core to resist tampering and weather damage. METOWARE focuses on both mechanical strength and a protected key mechanism to reduce the risk of picking or drilling.

• Zinc-alloy tubular lock cylinder with enhanced anti-theft geometry.
Weather-resistant finishes to limit corrosion and performance loss outdoors.
• Drill-resistant core design and sturdy bent-pin construction for impact resistance.

How easy is installation and daily use?

Installation is tool-free for most actions and the keyed-alike format simplifies repeated use. The universal coupler lock ratchets into place while the bent pins slip through receiver holes and the latch lock pins clamp the coupler handle closed.

• Tool-free ratchet and pin installation for fast on/off when hooking or unhitching.
• Single key operates every piece, reducing the need to manage multiple keys.
• Compact components store easily in a trailer toolbox or hitch compartment.

Who is this for? If you tow a boat, camper, utility trailer, or use hitch-mounted accessories and want one-key convenience plus robust protection, this METOWARE keyed-alike lock set fits the bill. It's suited to owners who haul frequently and need quick, dependable locking for a variety of couplers and receiver sizes without juggling multiple locks or tools. The kit is also a practical choice for fleets, rental operators, and homeowners looking to deter theft and accidental uncoupling with durable, weather-ready hardware.
