Prevent RV Theft With the Top Fifth-Wheel Locks

This post was updated on April 25th, 2024

One of The Best Ways to Protect from Theft Is Using a Fifth-Wheel Lock

Buying a fifth-wheel trailer is no small investment. Even a small, used RV will cost you tens of thousands. For newer, larger models, costs can get well into the hundreds of thousands. With so much money invested, you want to be sure your RV is protected. One of the best ways to protect from theft is using a fifth-wheel lock.

Let’s take a closer look at fifth-wheel locks and show you the best fifth-wheel locks on the market right now. 

What is a Fifth Wheel Lock, And Why Do You Need One?

A fifth-wheel lock is a device that you attach to the kingpin on your fifth wheel to prevent it from being connected to a hitch.

Usually, these locks come in the form of a round steel shaft that slides over the kingpin – although other designs do exist. For example, some fifth-wheel locks have a U-shaped design similar to a U-lock for a bicycle. Whatever the design, once the lock is in place, it makes it impossible for your kingpin to slot into the head of a fifth-wheel hitch.

Why do you Need a Fifth-Wheel Lock?

Fifth-wheel locks increase the security of your trailer when it’s parked and not in use. Without a lock, anybody with the right hitch can theoretically hitch up your trailer and drive away with it. You might think that nobody in their right mind would steal anything so large, but you’d be wrong

Because of the danger of theft, any fifth-wheel owners should have a fifth-wheel lock. A good lock is especially recommended if you own an expensive trailer or frequently leave your trailers parked in public places. If your RV will be parked anywhere unattended for a long period (like during the winter), you definitely want a lock on your kingpin.

A good lock won’t make theft impossible (as anyone who’s ever had a bike lock cut off can attest). But the lock acts as an added security measure that makes it more difficult for thieves to steal your RV. And the harder your RV is to steal, the more likely a would-be thief will skip over it for an easier target.

Lastly, the BOYISEN lock has an attached tag that advertises a kingpin lock is installed. This helps ward off potential thieves and ensures you never forget to take the lock off before hitching up your trailer and doing a tug test

  1. We have an Anderson hitch so the kingpin lock don’t work. We use locking x chocks on both sides to prevent theft or accidental movement.

  2. I use a Blaylock EZ Lock for King Pin. Very happy with it. Have owned a Blaylock EZ Lock for a gooseneck coupler for nearly 20 years and have been pleased. Both 5th wheel and gooseneck are made from aluminum, so no worries about rust/corrosion and are light weight for their size. Need to by a separate disc type padlock and you’re all set.
