The Best RV Hitch Locks of 2022

Master Lock has a couple of great features at a very affordable price. Many reviewers commented on the ease of installing the lock, since the key inserts on the side rather than the bottom of the lock. The color is a very bright red, making the lock easily visible and acting as a deterrent. A couple of reviewers struggled with the lock cylinder seizing up, causing them to need to break the lock. One reviewer, in particular, was surprised at how easily the lock was able to be bumped off the hitch using a hammer.

The Reese Towpower lock offers a traditional hitch lock design in an affordable package. With the ratchet arm being adjustable, the Reese can fit a range of hitch sizes. The bright yellow makes the lock highly visible as well. Reviewers commented that they use the Reese in combination with other theft deterrents, like wheel locks or keeping the trailer in a locked, gated area. One reviewer noted the tongue width was incompatible with their trailer. For most reviewers, the quality at this price felt like a good deal.

The Reese 7088300 is a nice upgrade from the 72783 if you’re looking for a universal lock that’s a bit more heavy-duty. Weighing in at almost four pounds, this lock is significantly larger than other locks in the same price range. With a protective cover over the keyhole, the Reese 7088300 aims to keep the lock working smoothing even out in the elements. Even with the protective cover, some reviewers still experience issues with the cylinder locking up so keep using a lubricate on the cylinder.

Overall, the Trimax UMAX100 offers a competitively priced lock for securing most sizes of trailer hitches. While many reviewers mentioned using this lock along with other trailer security items like cable locks and a locking crossbar, reviewers noted the barrel-shaped key as being different from other brands. Some reviewers noted most of the steel in the lock was located in the bar, with a plastic section covering the main bottom part of the lock. Another reviewer noted the lock was rusting very quickly after purchasing it.

The AMPLOCK is a significant jump in price from the other trailer locks in this review and the lock is not universal, so you might want to double-check your hitch size before ordering. As one reviewer commented, the lock is still cheaper than most insurance deductibles. If that argument convinces you, take a closer look at this lock. For starters, the lock is a hefty 12 pounds of stainless steel and cast iron. AMPLOCK states the lock is unpickable, using a cylinder lock with a rotating face. Most of the negative reviews involved the lock not fitting particular trailers. For example, this particular lock can not be used on a hitch with a flanged tongue, like Airstream, even if the hitch is the same size. Reviewers stated AMPLOCK’s customer service was very helpful with checking trailer specifications to make sure the lock is correct.
