METOWARE keyed-alike trailer lock set — 5/8" hitch pin & 1/4" coupler lock, weather-resistant steel, push-to-lock

METOWARE's keyed-alike trailer lock set secures your hitch and coupler with one key for fast, reliable towing protection.

Keep your trailer and tow vehicle protected without juggling multiple keys. This set pairs a heavy-duty 5/8" hitch pin lock with a 1/4" coupler lock, both opening with the same key and supplied with four identical spares. Built for common full-size trucks and trailers, the locks combine durable steel construction, weather-resistant finishes, and features that reduce noise and finish damage.

How does the hitch lock fit different receivers?

The hitch lock uses a 5/8" diameter pin and an extended 3.5" usable length designed to work with 2" and 2.5" receivers typically found on Class III–V towing setups. It secures through the receiver and requires no drilling or modification.

• 5/8" diameter pin for standard hitch openings
• 3.5" usable length to accommodate common hitch depths
• Compatible with 2" and 2.5" receivers on many trucks
• Fits Class III, IV, and V towing applications

How does the coupler lock protect my trailer and reduce rattle?

The coupler lock includes a protective rubber sleeve that cushions metal-on-metal contact and dampens movement. That sleeve prevents scratches to the coupler finish while minimizing the annoying rattling sound you hear on the road.

• Red rubber ring shields paint and metal from abrasion
• Sleeve acts as a noise dampener while towing
• Slips easily over the coupler latch for a tight fit
• Bright color offers quick visibility when inspecting hitch connections

What makes these locks durable in harsh weather?

Both pieces are constructed from high-strength steel and treated with a corrosion-resistant coating for long-term use in wet or salty environments. The hitch lock also features a watertight rubber cap to keep the locking mechanism free of debris and moisture.

• High-strength steel body for impact and shear resistance
• Electrophoretic black finish to resist rust and chips
• Rubber cap protects lock internals from water and dirt
• Designed for consistent outdoor exposure—rain, snow, and road salt

How quick and convenient is locking and key management?

The hitch lock offers a push-to-lock head so you can secure the pin instantly without inserting the key each time, which is useful in low light or cramped spaces. Both the hitch and coupler locks are keyed alike, and the set includes four matching spare keys so you can keep extras in the truck, toolbox, or with other drivers.

• Push-to-lock hitch head for one-step engagement
• One key operates both locks for simpler access
• Includes four identical spare keys for redundancy
• Saves time when attaching or storing your trailer
