A trailer lock can be used as an anti-theft device to secure a mating feature of a trailer, such as a king pin, against unauthorized hookups by tractors. The trailer lock can include a base plate for mounting on a wall of a trailer; one or more swing arms, which swing arms are pivotally connected to the base plate; and an engagement tube pivotally connected to the swing arms, which engagement tube defines an engagement feature integrally formed therein, such as a hollow recess, which engagement feature is capable of fitting to a mating feature of the trailer, such as a king pin. When the engagement feature is fitted to the mating feature of the trailer (for example, when an engagement tube with a hollow recess is positioned such that the king pin is within the hollow recess), it can prevent the mating feature from engaging a corresponding mating feature of a tractor, such as a fifth wheel.
