How To Lock A Uhaul Trailer

U-Haul trailers are great for getting your things from point A to point B, but what happens when you need to park and lock the trailer? For most people, the answer is nothing. However, if you’re a cautious U-Haul renter or just someone who values security, you might want to know how to lock a Uhaul trailer.

Unlocked trailers can be a huge inconvenience for any user of them because they’re not very secure. Most U-Haul locations have cameras and there are many stories online of people seeing their personal belongings being unloaded by other customers on camera. Therefore, it’s important to know how to lock a Uhaul trailer as an added layer of protection.

Lock The Back Wheel

One of the first things that you should do is to lock the back wheel of the trailer. This will prevent the trailer from moving with the rest of the truck, which can be helpful for keeping it in one place. If you don’t have a lock for the back wheel, be sure to put a brick or rock on the pedal so that it won’t move.

If you notice that the back wheel is loose and not attached to the axle, you might want to fix it before you park your trailer. U-Haul trailers have a tendency to come loose and fall off completely if you don’t have them tied down properly. A loose back axle can be dangerous for other drivers and is also a huge fire hazard.

Lock The Front Axle

The axle is an optional way to lock your trailer, but it’s recommended. It’s easy to do and you can use a bike chain, padlock or even a zip tie. This will prevent the trailer from being towed away by someone else who may want to steal it.

If you have the U-Haul trailer-dolly (a device that lets you tow a U-Haul trailer with a car), you may want to lock the axle on both the trailer and the dolly to prevent someone from taking the trailer with the car still attached. This is especially important if you’re parking in an area where theft is common.

Lock The Door With A Chain

Chaining the door of your U-Haul trailer is another way to make it harder for others to access your stuff. If you own a padlock, you can use that to lock the door shut. If you don’t have a padlock, you can use a bike chain or rope to tie the door shut. This may not be as secure as a padlock, but it’s much better than leaving the door unlocked.

If you’re using a bike chain to lock the door, make sure it’s long enough to wrap around the trailer at least once. This will make it much harder for someone to break the chain open.

Tips For Uhaul Trailer Security

  • Lock everything – The trailer, the truck and the dolly. If you don’t have the key, use a screwdriver to break the bolt inside the lock.
  • Check to make sure the trailer tires are tight and that the lights are working.
  • If you’re in an area where theft is common, park the trailer behind the truck so that the door is facing the street. This will make it harder for people to see what is inside the trailer.
  • Avoid parking in poorly lit areas and places that are close to lots of pedestrian traffic.
  • Make sure the U-Haul truck is locked as well.
  • Try using a GPS tracker on your trailer to monitor its whereabouts.


It’s important to remember that the methods discussed above are just a few suggestions for how to lock a Uhaul trailer. They aren’t guaranteed to keep your things safe and you may have to employ additional security measures depending on where you are.

If you’re renting a U-Haul trailer, don’t be afraid to ask the staff at the rental location how to properly lock the trailer. They want you to be as safe as possible while using the trailer, so they will be happy to answer any questions you have.
