I will not comment--just call a locksmith and prove that you own the trailer. **Q: How does it unlock?** A: There is a key. When you turn the key the whole base slides straight down and off. **Q: What is the difference between this and the umax50? does anyone know?** A: i kinda screwed up my locking system on the umax 50 trying to turn the key with ice in the lock. the key pulled out without it being lined up properly. im gonna buy the umax100 because it looks like its protected from the elements better. on the umax 50 all i did was drill the hole out with a titanium drill bit and gave it a few whacks with a mallet and it came right off. i am in no way an experienced theif, just watched a few youtube video because i didnt feel like paying a lock smith and I couldnt pick it on the first few tries. im sure its more of a visual deterrent, but I'm going to upgrade to this model. **Q: I need two locks keyed alike. How do I go about ordering them like this?** A: Amazon has them...... ## Frequently Bought Together - Trimax UMAX100 Premium Universal Dual Purpose Coupler Lock , Black - Trimax TCL65 Wheel Chock Lock , Yellow/Red, 7.25in - MAXXHAUL 70472 Solid Rubber Heavy Duty Black Wheel Chock 2-Pack, 8" x 4" x 6" --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/4571657-trimax-umax100-trailer-hitch-lock-1-7-8-2-5](https://www.desertcart.sc/products/4571657-trimax-umax100-trailer-hitch-lock-1-7-8-2-5) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-09-21*
