How to Lock a Trailer


Whether you use a trailer for moving furniture, carrying lawn equipment or trucking around band gear, your trailer's contents should be protected---not only during transportation but also when property will be left in the trailer overnight. You should lock the main entrances to the trailer and the tongue, which will prevent anyone from hitching up and driving off with your property.

Things You'll Need

  • Trailer tongue lock
  • 3 pad locks (with keys)

Trailer Tongue

  • Purchase a trailer tongue lock.

  • Open the hitch lock on the trailer tongue by squeezing it's handle and pulling upward. This is the same procedure as hitching a trailer to a standard ball hitch.

  • Open the tongue lock by inserting the key and turning it to the left. This will cause the shackle of the tongue lock to separate from the ball portion of the lock.

  • Insert the ball of the tongue lock into the hitch lock on the trailer tongue.

  • Squeeze the trigger of the hitch lock and push the handle back down to close the hitch. Place the shackle of the tongue lock back in place by turning the key to the left and sliding the bar over the trailer tongue and back into the lock. Remove the key when finished. The ball of the tongue lock takes the place of your truck's hitch when you drop the trailer somewhere.

Pad Lock locations

  • Place a padlock through the hole that passes through the trailer's hitch lock. This will keep an intruder from even opening the hitch lock to try and remove the tongue lock.

  • Place a padlock on the main door of the trailer. On most trailers, this is the large door in the rear that is used for unloading cargo. The handles of the door will have a hole that passes through them for padlock installation.

  • Place a padlock on your trailer chains. These chains are used as a safety back up when your trailer is hooked up to your vehicle. Unfortunately these items are quick and easy to steal right off of your trailer tongue. Lock the chain together to keep it securely fastened.
