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

METOWARE Keyed Alike Trailer Lock Set secures both your 5/8" hitch pin and 1/4" coupler with one key for fast, weatherproof protection.

Keep your trailer, boat, or RV attached only when you want it to be. This keyed-alike set includes a long-span 5/8" receiver lock designed for thick-walled 2.5" receivers and a matching 1/4" coupler lock, all operated by one key and backed by heavy-duty, corrosion-resistant construction. The combination of push-to-lock convenience, a pop-out release, and upgraded sealing makes this set practical for routine towing, winter roads, and marine environments.

How does the keyed-alike feature simplify trailer security?

Instead of juggling multiple keys, the METOWARE set gives you a single key for both the hitch and the coupler. Four identical keys are supplied so you can keep spares in sensible places without cutting new duplicates.

• One key fits both the 5/8" hitch pin and 1/4" coupler lock.
• Four identical keys included for backups or multiple drivers.
• Eliminates time wasted searching tangled keychains at loading areas.

Will these locks fit my heavy-duty truck receiver and trailer coupler?

Yes — the receiver lock has an extra-long 3.5" usable span and a 5/8" pin engineered to clear thicker walls found on Ram 2500/3500 and Ford F-250/F-350 trucks. The 1/4" coupler lock also spans common latch-type couplers for broad compatibility.

• 3.5" usable length accommodates thick-walled 2.5" receivers.
• 5/8" pin diameter for a snug, wobble-free fit on Class III–V hitches.
• 1/4" coupler lock fits most standard latch-style couplers.

How fast and easy is it to lock and unlock on the road?

Locking is tool-free and immediate: just push the pin to engage. To remove the locks, a 1/4 key turn triggers an auto pop-out release so you can unhitch quickly even when visibility or conditions are poor.

• Push-to-lock operation requires no wrench or tools.
• Auto pop-out on key turn for effortless removal.
• Designed for quick use at boat ramps, campsites, and loading docks.

How durable are these locks in salt, mud, and winter conditions?

The set is built for harsh environments: electrophoretic coating over steel plus a high-security Zinc Alloy core make the locks resistant to corrosion and tampering. An upgraded rubber dust cap seals the keyway against grit, salt spray, and moisture to maintain reliable operation season after season.

• Electrophoretic-coated steel body reduces rusting.
• Zinc Alloy core deters picking and drilling attempts.
• Rubber dust cap keeps salt and dirt out of the keyway.

Who this set is for: The METOWARE Keyed Alike Trailer Lock Set is ideal for owners of light- to heavy-duty trailers, boats, and RVs who tow with thicker-walled 2.5" receivers or who simply want a straightforward, single-key security solution. It’s a practical choice for contractors, weekend boaters, RV travelers, and fleet operators who need quick, durable, weatherproof locks that won’t slow down loading or launch routines.
