ABSTRACT:
An integral keyed lock (10) for a trailer trigger-lock coupler for use as an aftermarket kit or to be incorporated by an original equipment manufacturer. The coupler integral keyed lock (10) utilizes an actuating lever (20) that is configured to interface with and enclose a lock (52). The lock (52) is preferably keyed and includes an outward-extending plunger (54). The lock is disposed within the actuating lever, inside an enlarged portion (26) of one end. The plunger of the lock extends when actuated with a key and prevents rotational travel of the coupler trigger latch, thereby locking the trailer coupler until the plunger is retracted with the key.
