METOWARE Trailer Lock Set — Keyed Alike 5/8" Hitch Pin & 1/4" Coupler Lock, Corrosion-Resistant, Push-to-Lock

METOWARE Keyed Alike Trailer Lock Set gives you a single-key solution for both a 5/8" hitch pin and a 1/4" coupler lock, built for heavy-duty receivers and all-weather protection.

If you tow trailers, boats, campers, or utility gear, managing multiple locks and keys becomes a nuisance — and a security risk. This keyed-alike set from METOWARE includes a long-span 5/8" hitch pin for thick-walled 2.5" receivers and a 1/4" coupler lock sized to fit most latch-type couplers. Both locks operate with the same key (four identical keys included), use a push-to-lock mechanism for quick use, and are finished for corrosion resistance in marine and winter conditions.

How does the keyed-alike feature simplify trailer security?

Having both locks keyed the same eliminates carrying multiple keys and speeds up hitching and unhitching. You receive four identical keys so you can place spares in secured locations or share a backup with a trusted person. The uniform key profile also reduces fumbling in low light or bad weather.

• One key opens both the 5/8" hitch pin and 1/4" coupler lock
• Four identical keys included for backups
• Less time spent searching keyrings at ramps or campsites

Will the 5/8" hitch pin fit my heavy-duty receiver?

The hitch pin was engineered for larger receivers and thick-walled applications like Ram 2500/3500 and Ford F-250/F-350. It provides a 3-1/2" usable span and a snug 5/8" diameter to prevent wobble, making it compatible with Class III, IV, and V hitch systems. Measure your receiver opening and the required usable length to confirm fit.

• 5/8" diameter pin for secure fit
• 3-1/2" usable span for thick-walled 2.5" receivers
• Works with Class III–V hitch types

How quick and simple is locking and unlocking?

Both locks use a push-to-lock design so you can secure them without a key in seconds — ideal when your hands are full or conditions are poor. To remove, a brief 1/4-turn with the key triggers an auto-pop release for effortless unhitching. The mechanism minimizes fumbling and keeps operations fast during frequent use.

• Push-to-lock action for fast, tool-free securing
• 1/4-turn key release that auto-pops for easy removal
• Designed for repeated daily use at ramps, campsites, and job sites

How well does the set resist corrosion, picking, and environmental wear?

Materials and finishes were selected to withstand road salt, marine spray, and seasonal moisture. The pins feature electrophoretic coating and a zinc-alloy core that adds toughness against cutting or drilling attempts. A rubber dust cap keeps debris and water out of the lock cylinder to preserve smooth operation over time.

• Electrophoretic-coated steel resists rust and abrasion
• High-security zinc alloy core deters picking and drilling
• Upgraded rubber dust cap blocks water and grime

Who is this for? The METOWARE Keyed Alike Trailer Lock Set is aimed at owners of full-size trucks, RVs, boats, and utility trailers who need a rugged, quick-to-use security solution that fits thicker receivers. It suits frequent haulers, seasonal boaters, fleet managers, and anyone who prefers one-key convenience without sacrificing corrosion resistance or mechanical strength. If you need a durable 5/8" hitch pin with a matching coupler lock and spare keys for backup, this set covers typical towing, storage, and marine scenarios without complicated key management.
