The 10 Best Trailer Hitch Locks
This wiki has been updated 12 times since it was first published in October of 2018. If you leave your trailer unattended, what’s to stop some ne'er-do-well from absconding with your belongings? Our list of hitch locks includes options that provide security while your trailer is hooked up to your vehicle as well as models that fit over the coupler on your trailer’s tongue, preventing anyone from towing away your stuff while it’s sitting unhitched in your driveway. When users buy our independently chosen editorial selections, we may earn commissions to help fund the Wiki.

After spending some time reviewing our existing rankings for this category, and comparing them to available alternatives, we decided to move through this round of updates without making any substantive changes. Between pin-style offerings to protect connected trailers – like the Motormic Set and Connor Receiver – and a variety of designs aimed at ensuring parked trailers remain parked – like the MegaHitch Vault Pro and Amplock U-BRP2516 – we felt that the last editor for this page put together a nice mix of options, and saw no major advantages offered by any alternatives, neither in terms of price nor utility. So, in accordance with the age-old maxim “if it ain’t broke don’t fix it,” we’ve decided to leave this list untouched, at least until our next round of updates.

Discovered that the Blaylock TL-33 needs to be combined with an additional lock, but reports of its durability and effectiveness make it deserving of a spot on the list. Noted that some items, like the Trimax UMax25, Master Lock 389DAT and MegaHitch Vault Pro, are designed in bright colors to potentially deter theft based on visibility.
