Why this one works when the old one didn't
Every feature below exists because of a real complaint about single point locks.
Two locking points, not one
A single point lock gives a thief one loose spot to work. TowGuard locks the coupler and the pin at the same time, so there is nothing single left to pry.
Keyed alike
One key operates both locks, so you are never digging through a ring of near identical keys in the dark.
Powder coated steel
Rated for a trailer that lives outside in real weather, not a lock that only looks tough on the shelf.
Tested against real tools
Hammer, rock, and a grinder in the field, not just a claim on a box.
TowGuard versus the lock you already have
| What matters | TowGuard | Classic single point lock | No lock |
|---|---|---|---|
| Locking points | Two, coupler and pin | One | Zero |
| Held up to a hammer or rock on camera | Yes | Not tested | Not applicable |
| Keyed alike | Yes, one key | Varies by brand | Not applicable |
| Weather protection | Powder coated steel | Painted, varies | None |
| Replacement if it fails | Lifetime | Varies by brand | Not applicable |
Why the lock you already have might not be doing much
A lot of hitch locks are one piece that slides over the ball and hopes for the best. Loose enough to wiggle in your hand, which is exactly what a hammer or a rock needs to pop it off in a few hits. One reviewer of a popular lock put it plainly after trying it for a season: it moved around quite a bit, and it was not very difficult to defeat.
That is not a knock on any one brand. It is how a single point lock works. TowGuard was built to close that gap by locking two points instead of one, so there is nothing single left for a thief to work loose.
How the two point lock actually works
-
1
Slide the coupler lock over the ball
Push up until it seats. No key needed to lock it in place.
-
2
Set the pin lock through the latch
Now the coupler cannot accept a ball at all, hitched or not.
-
3
One key releases both
Keyed alike, so getting back on the road takes one key, not two.
Think of it like a deadbolt and a chain lock on the same door. A thief who beats one still has to beat the other, and most give up long before that.
See the two point system in fifteen seconds
No guessing how it works. The coupler lock seats over the ball, the pin lock closes off the latch, and the whole assembly moves as one piece.
Every step, start to finish
No special tools and no trip to the hardware store. Set it once and it stays put until you use your key.
Built for anyone who tows
One hand, one motion to lock. No wrestling with a stiff mechanism every time you park.
What actually changes after you switch
Before
Walking out to the driveway at night just to double check the trailer is still there.
After
Locking up once and not thinking about the trailer again until you need it.

Questions before you lock it down
I already bought a hitch lock before and it did nothing. How is this different?
Most locks people try are one piece that slides over the ball and relies on a single point to hold. TowGuard locks the coupler and the pin at the same time, so a thief has two separate points to beat instead of one loose one. It is also powder coated steel, built to hold up outdoors rather than just look tough in the listing photo.
Will this fit my trailer?
TowGuard is built for standard couplers. Measure the opening on your coupler before ordering and choose the matching size at checkout so the pin seats fully and locks.
Can someone just hammer or cut this off?
No lock is completely indestructible with enough time and the right tools. What TowGuard changes is how long that takes. The two point design has held up against a real attempted theft, including a grinder, caught on security camera. A single point lock does not get that kind of test.
Does the key stick or get hard to turn?
Make sure the lock is fully seated before you turn the key, the same way you would with any coupler lock. A light coat of dry lubricant on the pin once a season keeps it turning smoothly through winter and salt air.
How fast will it ship?
Orders process in 1 to 2 business days and arrive in 5 to 10 days after that, depending on your location.
What if it arrives damaged or stops working?
TowGuard is covered by a lifetime replacement guarantee. You are also covered by a 90 day money back guarantee from the date you receive it.
Will it rust or hold up outside?
The body is powder coated steel, built for a trailer that lives outdoors through rain, snow, and salted roads, not just a garage.
Do I need any tools to install it?
No. Both locks slide on and set by hand. No drilling, no wrench, no trip to the hardware store.
