A vehicle door includes a latch mechanism having a fork-bolt that is configured to engage a striker and prevent opening of the vehicle door when the latch mechanism is in a latched configuration. The latch mechanism includes a lock mechanism that disconnects an exterior door handle from the latch mechanism when the latch mechanism is locked. The lock mechanism includes a lock lever having a center of mass that is spaced apart from an axis of rotation of the lock lever whereby the lock lever rotates and locks the latch mechanism in the event of a side impact.
