Trailer Hitch Lock Systems

There are trailer locks available for both the ball of the hitch and/or the receiver. These keyed locks can provide added security to your trailer. The keyed lock provides the most protection to your trailer but it can be the most expensive. The standard hitch pin lock might cost you less with the main draw back being that it doesn’t provide as much security as a keyed lock.

Other Lock Systems

If you are using a different lock system, you will need a lock to fit that design. Depending on what kind of lock you need, it could be one you'll buy at a local store or you may need to use a custom lock and key made especially for your trailer security needs.

It is recommended you get a lock that is made to fit the exact design of your trailer if you’re not sure. A professional lock should have less room for tampering and breaking into than a standard lock.

Here is a list of basic lock systems along with their information and product links with more details on each of the lock systems.

Trailer Tongue Locks

Chains and locks are best for securing both the trailer hitch and the entire trailer to a fixed object. Before you start wrapping the chain around a trailer, make sure of the following safety steps.

Check for any type of damage to the trailer or the trailer hitch. If you see any damage, it is best to fix it before you continue with securing the trailer.

Put on safety glasses before you start working with the chain.

Put on heavy duty gloves to protect your hands from the chain.

To lock a trailer with chains, you will need the following:

  • A trailer with a trailer hitch and a trailer tongue
  • A thick metal chain with eyelets
  • A heavy duty padlock

Place the chain through the trailer hitch and the trailer tongue.

Then put on the padlock and lock it.

Wheel Locks for Trailers

If you are looking for the quickest and best way to deter theft from your trailer, wheel locks are an easy choice. When shopping for a wheel lock, consider the strength of the lock, how easy it is to install, and if it fits your wheels.

You'll need to know what kind of trailer you have in order to ensure the wheel locks you choose will fit. Some options you can consider are fork locks and wheel clamps.

Wheel locks are a quick, easy and effective way to add trailer security and they don't create any damage to your trailer. If a thief uses excessive force to remove a wheel lock, it will break off and save your trailer from the rest of the damage.

The Ultimate Combination To Lock A Trailer

The most effective combination to lock your trailer, is by using Trailer Alarms and Hitch Locks. Trailer alarms require you to place a pin in the hole of a locking pin into the receiver of your trailer hitch. This will set off your immobilizer, which will beep to inform you that your trailer is not secure. Then, to set off the alarm, you need to enter the correct pin number.

When combined with a Hitch Lock, your trailer will be secure even if a thief changes the pin numbers of your trailer alarm. Because Hitch Locks are used on trailer ball, they are sold separately from Trailer Alarms. Hitch Locks are usually sold in pairs, one on each ball hitch.

Other options include locking your entire trailer. However, this is not the best option. If you really want to lock your trailer completely, be sure to use a trailer lock/cable combination. All you need to do is disconnect the front cable to set off the alarm.

If you don’t have access to a cable lock, there are a few B and W Hitch Lock systems to secure your trailer during parking and transport.
