I have alot of locks. All on same master lock key** A: I have 6 of these they can be rekeyed. Try a different lock smith. I would also say to have it keyed with the pad locks so you always only have one key for lots of locks. **Q: Can I get a key number the same as locks i Have** A: It would depend on the key # needed. Please feel free to message us with the key # you are looking to match to and we can tell you if it can be done. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***B on 19 April 2024* Great product ### ⭐⭐⭐⭐⭐ Review *by E***Z on 16 February 2026* Bastante práctico de usar y te da más tranquilidad de los distintos tipos de candados para cople este es mi favorito ### ⭐⭐⭐⭐⭐ Review *by S***N on 2 June 2024* At first I thought it didn’t fit my hitch - to telly my fault. There are no instructions with it - just the picture on the outside of the box. I didn’t think to list the lever on the hitch so the lock would rest inside and then once I closed the lever I understood how it was supposed to work. Then turn the key and go. 👍. ## Frequently Bought Together - Master Lock 379ATPY Universal Trailer Hitch Lock , Black - MAXXHAUL 70472 Solid Rubber Heavy Duty Black Wheel Chock 2-Pack, 8" x 4" x 6" - RETRUE Trailer Tongue Coupler Lock, Trailer Hitch Lock,Dia 1/4 Inch, 3/4 Inch Span for Tow Boat RV Truck Car's Coupler, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/276055145-master-lock-379atpy-universal-trailer-hitch-lock-black](https://www.desertcart.ph/products/276055145-master-lock-379atpy-universal-trailer-hitch-lock-black) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-04-23*
