A kingpin locking system for securing a kingpin on a trailer to a tractor is provided. The system comprises a C-shaped member having a main body portion, a first jaw portion, and a second jaw portion. A first spring member is mounted between the center portion and the first jaw portion with the first spring member allowing the first jaw portion to move in a general direction toward and away from the second jaw portion. A key mechanism activates a locking mechanism to lock the first and second jaw portions together and deactivates the locking mechanism to unlock the first and second jaw portions. Upon positioning the C-shaped member about the kingpin and moving the first jaw portion into contact with the second jaw portion, the key mechanism activates the locking mechanism thereby securing the first and second jaw portion together and securing the trailer to the tractor.
