Funmit Trailer Hitch Security Lock Set — Yellow keyed-alike kit with universal ball lock & 1/2"-5/8" hitch pins

The Funmit Trailer Hitch Security Lock Set is a complete yellow locking kit that secures ball mounts, couplers and hitch pins using two matching keys for simplified access.

Protecting trailers, campers, boats and cargo starts with robust mechanical locks designed for the rigors of towing and outdoor storage. This kit from Funmit packages multiple hitch and coupler locks in one set, so you can secure common connection points without juggling different keys. Constructed from hardened hardware and finished for weather resistance, the set balances convenience and theft deterrence for owners who tow regularly.

What components are included and why does one-key convenience matter?

The set contains a universal trailer ball lock, a 5/8" straight hitch lock, 1/2" and 5/8" bent hitch locks, plus a coupler lock — all keyed alike to two matched keys. One-key systems cut down on lost or mismatched keys, making quick hookups and daily use hassle-free.

• Universal ball lock for standard trailer balls.
• Straight and bent pins for different receiver/clevis styles.
• Coupler lock secures the latch mechanism on a trailer's coupler.
• Two identical keys: backup and primary for multiple users.

How durable and secure are these locks for outdoor towing?

Funmit designed the components from solid hardware-grade materials that resist corrosion and stand up to frequent use. Ratings indicate the assemblies can handle heavy loads and the construction reduces common attack methods like picking and prying, improving protection during storage or while hitched.

• Hardened pins and bodies resist bending and shear forces.
• Weather-resistant finish prevents rust and seizing.
• Reinforced locking mechanisms deter picking and drilling.
• Load capacity suitable for most trailer applications.

Is installation straightforward for one person, and will it fit my trailer?

Installation is quick and intuitive: pins slide through the hitch or coupler and lock securely with the included keys. The kit is built to fit a wide range of U.S. trailer hardware sizes and includes both straight and bent pins to accommodate different receiver orientations.

• Push-pin action for fast locking and removal.
• Adjustable fit across common 1/2" and 5/8" hitch diameters.
• Compatible with many standard trailer couplers and ball mounts.
• No special tools required for routine use.
