RETRUE Cyber Lock Trailer Coupler Tongue Lock, Silver — Heavy-Duty 1.2" Span, One-Push Security

RETRUE Cyber Lock™ Trailer Coupler Tongue Lock is a heavy-duty, one-push silver lock with a 1.2" span that secures most trailer couplers quickly and reliably.

When you need fast, robust protection for trailers, the RETRUE Cyber Lock delivers a blend of strength, ease-of-use, and weather resistance. Built from high-strength steel with a wide 1.2" span, this coupler tongue lock fits a broad range of latch designs, making it a practical choice for fleet managers, multi-trailer owners, and frequent haulers. The bright silver finish is durable and the included rubber cap helps keep the keyway clean in wet or dusty conditions.

How does the Cyber Lock fit different trailer couplers?

The Cyber Lock features an upgraded maximum span of 1.2 inches to cover more tongue sizes and latch profiles than many standard coupler locks. That wider range reduces the need for multiple lock types and simplifies inventory for businesses.

• 1.2" maximum span accommodates common coupler and latch designs
• Universal fit reduces the number of different locks needed
• Suitable for both commercial fleets and personal trailers

What makes the lock easy and fast to use?

RETRUE designed the Cyber Lock with one-push locking so you can secure your trailer with a single motion—no keys required to engage. Unlocking is equally simple with a half-turn action, making it fast to release when you’re ready to hitch up.

• Push-to-lock mechanism for instant security
• Half-turn unlocking minimizes fumbling and saves time
• Ideal for quick stops, frequent hookups, and busy loading routines

How secure and durable is this trailer tongue lock?

The body is forged from heavy-duty steel designed to resist cutting, bending, and prying attempts. Two reinforced keys are included, made thicker to resist bending and extend service life—so you have a reliable backup on hand.

• High-strength steel body for robust physical protection
• Two ultra-durable keys with reinforced thickness
• Padlock-style form factor deters common tampering methods

Will it stand up to weather and road conditions?

Yes—RETRUE added a protective rubber cap that seals the keyhole from dust, moisture, and debris to maintain smooth operation. The cap helps prevent corrosion and freezing in cold climates, keeping the lock functional across seasons.

• Snug rubber keyhole cover protects from rain, mud, and dust
• Resists corrosion to maintain long-term reliability
• Works well for trailers stored outdoors or used in variable conditions

Who is this for: The RETRUE Cyber Lock™ is built for anyone who wants a fast, dependable way to secure trailers—commercial fleet operators, equipment haulers, contractors, and recreational users who need a single lock that fits multiple couplers. If you value quick engagement, solid construction, and weather-resistant detailing in a compact silver package, this lock is engineered to meet those needs without extra complexity.
