Frequently Asked Questions (FAQ)

• Question: How does the RETRUE Heavy Duty Trailer Lock keep my trailer safer than other locks?
  Answer: The RETRUE Heavy Duty Trailer Lock works by forming a tight physical shield around the coupler. Its thick steel and cast iron body can resist cutting tools and prying. The unique keyhole shape is designed to foil lock-picking, so it cannot be opened with common lock tools. Many standard locks can be bypassed quickly by thieves. This lock uses premium materials to fight these attacks. Its size and weight make removal very difficult without drawing attention, even with power tools. Owners report that just seeing the lock can scare criminals away before they even try.
• Question: Will the RETRUE Trailer Lock fit my specific trailer coupler?
  Answer: The RETRUE Trailer Lock is made to fit 2 5/16" ball couplers with a flange. This covers many trailer types, including straight tongue, A-frame, and some adjustable couplers. To be sure, measure your coupler before buying. The flange should have enough space for the lock to slide over and onto the ball. If your trailer uses a different size or style, consider checking our main automotive locks section for other options. Correct sizing is important for maximum security.
• Question: How does the weatherproofing work, and what if I use my trailer in rough climates?
  Answer: The RETRUE lock is built to last in all weather. The rubber cap that comes with the lock fits tightly over the cylinder. This keeps moisture, grit, and UV rays from harming the inner locking parts. In ice and snow, the lock does not freeze up easily if the cap is on. In summer heat, it resists sun damage and stays easy to unlock. For rough climates—coastal, mountain, or high humidity—the chrome-plated steel fights off rust and corrosion. Owners in challenging areas praise the lock’s reliability even after years of outdoor use.
• Question: What if I lose both keys or if the lock sticks?
  Answer: RETRUE provides two precision-cut keys for each lock. Keep one key in a safe spot. If both keys are lost, professional locksmiths can often help unlock the device, though it will take effort due to its security. If the mechanism is ever sticky, a drop of lubricant solves most problems. The weather cap also helps keep the keyhole clean and reliable over time. For extra help, the RETRUE support team responds quickly to warranty or key replacement questions.
