TOWSWELL Trailer Hitch Lock for 2" Receiver — 5/8" Pin, 2-Pack with 4 Keys, Weatherproof Hardened Steel

The TOWSWELL Trailer Hitch Lock is a weatherproof, heavy-duty 5/8" locking pin designed to secure 2" (Class III/IV) receiver hitches, offered as a 2-pack with four keys for added convenience.

When you tow a trailer, bike rack, cargo tray or boat, a reliable receiver lock prevents accidental disengagement and deters opportunistic theft. TOWSWELL’s hitch locks use hardened steel pins, a black corrosion-resistant finish and a simple push-to-lock operation so you can secure your 2" hitch quickly and trust it in wet or dusty conditions. Each set includes two independent locks and four keys so you can outfit multiple vehicles or keep a spare key on hand.

How durable is the TOWSWELL hitch lock under different weather conditions?

The lock is made from high-quality steel with a black protective coating to resist rust and wear. A rubberized key slot cover protects the cylinder from moisture, sand and road grime, helping the lock operate smoothly season after season.

• Solid steel construction reduces bending or deformation under load.
• Black finish provides corrosion resistance for marine or winter use.
• Rubber key cap blocks water and dirt, extending cylinder life.
• Push-to-lock design minimizes internal exposure during use.

Will this lock fit my trailer’s 2" receiver and how easy is it to use?

Yes — the TOWSWELL pin is 5/8" in diameter with a 2-1/2" span designed for standard 2" Class III and IV receiver tubes. Installation is straightforward: insert the pin, push until it clicks, and confirm by pulling the head. Unlocking requires a simple 1/4-turn of the key and the pin will pop up for removal.

• 5/8" locking pin sized for 2" receiver tubes (Class III/IV).
• Push-to-lock mechanism gives audible feedback with a click.
• Key operation requires a 1/4-turn for quick release.
• Each lock supplied with two independent keys for backup.

How does the 2-pack and keying work for multiple hitches or vehicles?

The package contains two separate locks and four keys. These locks are keyed differently (KD), meaning one key cannot open the other lock — useful when you want distinct keys for different trailers, or to keep a spare secure. Having two locks and four keys gives options for paired use on dual hitch setups or distribution among drivers.

• Two independent locks included in each package.
• Four keys total: two keys per lock for emergency access.
• KD (keyed different) configuration prevents cross-opening.
• Ideal for one vehicle and one trailer, or two vehicles.

How secure is the TOWSWELL lock against theft and accidental release?

The lock enhances towing security by replacing a standard hitch pin with a keyed locking pin that resists casual theft and accidental removal. While no lock is impervious to determined theft attempts, the solid-steel pin, protected cylinder and secure push-to-lock mechanism offer a meaningful deterrent and reliable retention while towing.

• Keyed locking pin prevents unauthorized removal of the hitch.
• Robust pin resists pry and bend attempts during normal use.
• Protected keyway reduces risk of corrosion-related failure.
• Visible lock acts as a deterrent to opportunistic thieves.

Who is this for: The TOWSWELL Trailer Hitch Lock 2-pack suits vehicle owners who tow trailers, boats, bike racks or cargo carriers using a 2" receiver and want a durable, easy-to-use locking pin. It’s aimed at drivers who need weather-resistant hardware, a clear audible lock confirmation, and spare keys for shared vehicles or multi-hitch setups.
