Explore Our Hitch Locks
When your trailer sits parked, a hitch lock is your first line of defence against theft. It stops anyone from hitching up and driving off. Each unit slides into the receiver tube to serve as a dedicated receiver lock that blocks the hitch pin. We machine every lock from ductile iron paired with stainless steel, so you get trailer security built to last.
5/8" Diameter Hitch Locks
If you drive a full-size truck or SUV with a Class III, IV, or V hitch, our 5/8 hitch lock range is made for your receiver. The lineup covers a standard model, an adjustable unit that handles varying receiver depths, and a folding pole design for pin holes that are hard to reach. Every option replaces your factory receiver pin with a hardened, keyed hitch pin lock that nobody can remove without the right key.
1/2" Diameter Hitch Locks
For lighter-duty Class I and II receivers, the 1/2 hitch lock is sized for the narrower 1/2 inch tube. Choose between a standard version and a folding pole model. Both feature the same CNC-machined ductile iron body and anti-pick disk cylinder found on our larger receiver lock options. And because the key system carries across the full AMPLock range, the same key that secures your hitch also works on our trailer coupler locks.
Why Choose AMPLock for Hitch Locks?
CNC-Machined Anti-Theft Construction
We build every hitch lock from ductile iron with stainless steel moving parts, the same foundation you'll find across our entire trailer locks catalogue. An anti-pick disk lock cylinder with millions of unique combinations stands up to picking, drilling, and brute force. That's the difference between a basic pin and a proper anti-theft hitch lock that delivers genuine security.
Keyed-Alike System Across All Locks
One key runs every AMPLock product you own: hitch locks, coupler locks, and kingpin locks. When you place a new order, we can match it to a key number already in your pocket, so expanding your setup doesn't mean juggling more keys. It turns a single hitch lock key into a full trailer lock system that grows with you.
Free Shipping and 5-Year Warranty
Free shipping applies to every order heading anywhere in Canada or the United States, and you get 30 days to return anything that doesn't suit your rig. Register your lock and it's covered by a 5-year warranty, because real protection shouldn't come with fine-print loopholes. That's a hitch lock warranty that backs up the build quality.

Frequently Asked Questions About Hitch Locks
What Diameter Hitch Lock Fits a Standard Receiver?
Full-size trucks and SUVs typically need a 5/8 inch receiver, which pairs with our 5/8" hitch locks designed for Class III, IV, and V hitches. Compact vehicles with Class I and II hitches use the 1/2 inch size. Measure your receiver tube opening before ordering so you get the exact pin diameter.
What Materials Are AMPLock Hitch Locks Made From?
Each lock combines a ductile iron body with stainless steel moving parts, all sourced from North America. The patented push-and-lock mechanism means tool-free installation. Just slide it in and lock it. An anti-pick disk cylinder inside resists tampering, picking, and drilling.
Can One Key Operate Multiple AMPLock Products?
Absolutely. Our keyed-alike system means a single key controls your hitch lock, coupler locks, and kingpin locks across the entire AMPLock range. Request matching at checkout, and we can even retroactively match your new order to a key number from a previous purchase.
Does AMPLock Offer Free Shipping on Hitch Locks?
Every hitch lock ships free to addresses in Canada and the United States. If it isn't the right match, you've got 30 days to return it at no charge. Once registered, each lock is backed by a 5-year warranty.
What Is the Difference Between Standard and Folding Pole Hitch Locks?
The standard hitch lock inserts directly into the receiver tube, while the folding pole version extends further to reach pin holes that are recessed or tucked behind obstructions. Both models share the identical CNC-machined construction, disk lock cylinder, and keyed-alike compatibility, so the choice comes down to how accessible your receiver pin is.
