METOWARE Keyed Alike Trailer Lock Set — 5/8" Hitch Pin & 1/4" Coupler Lock, Weather-Resistant with 4 Spare Keys

METOWARE Keyed Alike Trailer Lock Set includes a 5/8" push-to-lock hitch pin and a 1/4" coupler lock that both use the same key for fast, secure towing protection.

Keep trailers, campers, and cargo safe with a matching pair of locks engineered for everyday towing. This METOWARE set combines a heavy-duty 5/8" hitch pin (with a long 3-1/2" usable shaft) and a 1/4" coupler lock outfitted with a red rubber sleeve. Both locks arrive keyed alike and include four identical spare keys, so you can lock quickly without juggling multiple keys or worrying about mismatched cylinders.

How does the keyed-alike feature simplify trailer security?

Having both locks keyed alike means one key operates the hitch pin and coupler lock, reducing the time and hassle at the hitch. It’s ideal when you frequently attach and detach trailers or want a single, reliable key for storage and transport.

• One key opens both the 5/8" hitch lock and the 1/4" coupler lock
• Includes four spare identical keys for backups and multiple users
• Eliminates time spent searching for separate keys when hitching up
• Useful for fleet drivers, contractors, and recreational users

Will the 5/8" hitch lock fit my vehicle and trailer receiver?

The hitch pin is sized to work with common Class III, IV and V receivers, including 2" and 2.5" openings. With a 5/8" diameter and a 3-1/2" usable length, it accommodates larger receivers found on trucks like Ford F-150/F-250, RAM, and Silverado models.

• 5/8" diameter pin for Class III–V receivers
• 3-1/2" usable shaft length fits a wide range of receiver depths
• Compatible with 2" and 2.5" hitch openings
• Designed for heavy-duty towing applications and common truck models

How does the coupler lock protect the trailer and reduce rattling?

The 1/4" coupler lock includes a red rubber sleeve that cushions contact points to prevent scratches and minimize noise. That protective sleeve also helps maintain a snug fit inside the coupler, reducing vibration and metal-on-metal rattling while driving.

• Red rubber ring prevents paint damage and wear on coupler surfaces
• Reduces on-road rattle for quieter towing
• Bright sleeve improves visibility for quick inspection and removal
• Tight fit discourages opportunistic theft attempts at the coupler

How weather-resistant and durable are these locks?

METOWARE built the locks for all-weather use with high-strength steel, an electrophoretic black finish, and a watertight rubber cap on critical components. The materials resist rust and corrosion from rain, snow, and road salt so the locks keep working season after season.

• High-strength steel core for robust mechanical resistance
• Electrophoretic black finish offers corrosion protection
• Watertight rubber cap seals the cylinder against moisture
• Push-to-lock hitch pin allows keyless closure in dim or tight spaces

Who is this for? This METOWARE keyed-alike trailer lock set is aimed at truck owners, fleet operators, campers, and contractors who need reliable, easy-to-use security at the hitch. Choose this set if you want a heavy-duty hitch pin that fits common receivers, a coupler lock that protects finishes and reduces noise, and the convenience of a single key with spare copies for backups.
