The Best Towing Hitch Locks of 2019

Table of Contents

Trailers are cumbersome, heavy-duty assets that no thief would ever think to steal in a million years, right? Of course, that’s not true. Trailers are difficult to store and tether, and are often left with minimal security, which makes them relatively easy targets of theft.

A simple, low-cost trailer hitch lock can make all the difference in the world in protecting your trailer. Especially if you run a business that relies on trailers for hauling equipment, this minor investment can save you days of lost productivity. If nothing else, a towing hitch lock can be a great visual deterrent to keep potential thieves from making off with your trailer.

Motormic Trailer Hitch Lock Pin Set

A surprising number of trailer hitch locks attempt to overcomplicate what should be a relatively simple mechanism. Made of durable, long-lasting materials, this nearly universally compatible lock installs easily and provides dependable protection.

Pros: This lock is made of black powder-coated forged steel that resists corrosion and any other weather-related decay. Its locking mechanism is as simple as can be; in fact, you don’t even need the key to lock it! (it features a unique push-to-lock capability). For its modest price in its class, this lock is truly a feat of engineering.

Cons: While the build quality on the lock itself is super sturdy, the end cap that protects the lock could definitely be improved upon. The hard plastic is a bit unreliable and as a result the actual lock can take on moisture and grime.

Master Lock 389DAT Universal Trailer Lock

From industry leaders Master Lock, the 389DAT is a great option for those looking for a no-fuss way to secure a trailer. This easy-to-install trailer lock fits virtually all trailer couplers and features an advanced locking mechanism that resists picking and prying. 

Pros: The main positive of this Master Lock is its ease of use. While other comparable locks can require some contortion on the part of the user to navigate locking and unlocking, the 389DAT provides a straightforward attachment and removal. And, not only is its fiery red finish visually appealing, but its corrosion-resistant as well.

Cons: Because this lock relies on common keyed-alike technology for its locking mechanism, it may not be the most secure option for those that need to protect a high-value trailer asset.

Best Vehicle-Specific Hitch Lock

BOLT 7018448 Receiver Lock

The majority of trailer hitch locks rely on standard keyed-alike locking mechanisms which, while they offer a great additional level of security, can be relatively easily cracked or replicated. The BOLT 7018448 eschews keyed-alike technology in favor of a more unique approach, allowing you to open the lock with your car key.

Pros: The main distinguishing factor is the One-Key Lock technology, which eliminates the need to carry multiple keys. This BOLT lock reads your ignition key the first time you use it and imprints on that unique code. But even beyond this one-of-a-kind technology, the lock is completely weatherproof, built of sturdy stainless steel, and features a super-secure double ball bearing locking mechanism.

Cons: Because the lock is designed for use with specific automobiles, there are some issues with compatibility. Many Chevrolet, GMC, Ford, Chrysler, Jeep, Dodge, Ram, Toyota and Nissans work with the lock, but it’s important to choose the right model to guarantee compatibility.

Best Lock and Hitch Combo

Weigh Safe LTB6 Lock Hitch

Adding a lock to an existing trailer hitch is a great way to provide additional security to a valuable asset. But if your existing hitch could also use an upgrade, there are options available that combine an entire trailer hitch unit with a built-in lock for not only added towing power but also added asset protection. The LTB6 from Weigh Safe is a great way to kill two birds with one stone.

Pros: This hitch and lock combo is a heavy-duty upgrade to your existing configuration. Made of rugged, rust-resistant stainless steel, the hitch also features a 180-degree slider and a six-inch drop drawbar so it can be fully adjusted to accommodate most-any trailer. Combine that with a keyed-alike hitch pin lock and you’ve got a winning team.

Cons: The main drawback to a full trailer hitch upgrade is it can be a cost-prohibitive endeavor. If you need the extra towing capacity, however, the LTB6 may be well worth it for you.

Towing Hitch Lock Methodology

Best Towing Hitch Locks Review
Towing hitch locks can make all the difference in securing large assets.

There are a number of distinguishing factors that separate trailer hitch locks from being merely serviceable to being truly great. Some of it depends on the handiness of the end user, while other factors rely on the scale and application of the lock. Protecting a low-investment trailer that you use to haul yard waste to the dump is a different gambit than guarding business-dependent trailers that are used to transport heavy machinery out to job sites.

  • Build material: While the industry standard is some variation on stainless or reinforced steel, the locks that stood out put added effort into weatherproofing the lock. There’s nothing worse than having a strong lock that becomes unusable due to corrosion or rusting over time.
  • Ease of installation: Not everyone is as savvy when it comes to hardware. Towing hitch locks shouldn’t be difficult puzzles that you the end-user has to solve. Simplicity in design was important in selecting the best trailer hitch locks because laboring over the installation of a security measure on an asset that you may only use a few times a year is frustrating (and avoidable).
  • Key type: While a majority of trailer hitch locks used keyed-alike locking mechanisms, we found that presents some reliability issues. Keyed-alike locks can be more easily cracked or tampered with, or flat-out opened with generic keys.

Towing Hitch Lock Tips

Selecting the right lock for your trailer hitch can be tough, because many of the products on the market have similar features and clock in at similar price points. So what should you keep an eye out for?

  • Weatherproof design: Odds are, your trailer is going to be kept outside, in the elements. Look for a lock with some form of weatherproofing that will resist rust and corrosion. If you’re considering a rod-style lock, look for one with a reliable end cap that covers the locking mechanism.
  • Visual deterrent: If your trailer is at relatively low risk of being stolen, the mere presence of a towing hitch lock may be all you need to keep thieves at bay. Consider a lower-cost lock that stands out with a brighter paint job to send the message that your trailer is not to be trifled with.

Recap of the Best Towing Hitch Locks of 2019

Protecting a trailer can be as simple as installing a lock and forgetting it; sometimes all you need is to let others know that you take security seriously. But if your business hinges on having a reliable, powerful lock, there are towing hitch lock options more than up to the task of guarding your valuable assets.
