An easy to use trailer anti-theft device that forms an integral part of said trailer comprising a front exterior wall mounted locking mechanism having a rotatable lock bar extending therefrom with the lock bar having an upper arm pivotally and swivelably connected to a lower swing bar that can be unlocked and moved from a stored position to a downwardly depending blocking position. The lock bar has a partially rotative lower swing arm that under force extends under the trailer substantially in the direction of the trailer king pin. A trailer lock assembly can include a housing mounted on a front wall of a trailer, an upper arm operably connected to the housing, and a swing arm pivotally connected to the upper arm. The swing arm is capable of pivoting under the bottom of the trailer in order to prevent a tractor's fifth wheel from engaging the trailer's king pin. The swing arm can also be swivelably connected to the upper arm to compensate for angular swing arm movement when a tractor attempts to hook up with the trailer from an angle.
