Claim:
A closure latch for use in holding a vehicle door closed against a vehicle body, the closure latch comprising: a ratchet mountable to one of the vehicle door and the vehicle body, movable between an open position and a closed position, wherein in the open position the ratchet disengages from a striker that is mountable to the other of the vehicle door and the vehicle body, and wherein in the closed position the ratchet is positioned to retain the striker, wherein the ratchet is biased towards the open position; a pawl movable between a ratchet locking position wherein the pawl holds the ratchet in the closed position and a ratchet release position wherein the pawl permits the ratchet to move to the open position, and wherein the pawl is biased towards the ratchet locking position; an inside door release lever operatively connectable to the pawl; and a lock including: a lock link movable between an unlocked position wherein the lock link operatively connects the inside door release lever to the pawl, and a locked position wherein the lock link operatively disconnects the inside door release lever from the pawl, wherein the lock link is biased towards the unlocked position; a first cam operatively connected to the lock link, wherein the first cam is rotatable between an unlocking range wherein the first cam permits the lock link to move to the unlocked position, and a locking range wherein the first cam moves the lock link to the locked position; and an override member connected for rotation with the first cam and rotatable between an actuatable range and a non-actuable range, wherein when the override member is in the actuable range the inside door release lever is operatively connected to the override member such that the inside door release lever is movable to drive the override member to a selected position which brings the first cam to the unlocking range, and when the override member is in the non-actuatable range the inside door release lever is operatively disconnected from the override member, wherein the lock is positionable in an unlocked state in which the lock link is in the unlocked position, wherein the lock is further positionable in a locked state in which the lock link is in the locked position, the first cam is in the locking range and the override member is in the actuatable range, and wherein the lock is further positionable in an additional locked state in which the lock link is in the locked position, the first cam is in the locking range and the override member is in the non-actuatable range.
