A system and method for selectively enabling fluid communication between two volumes, the system including a tubular having a port housing with at least one port, a member disposed with the tubular and movable between a closed position in which the port is closed and an open position in which the port is open, a lock element positively engaged with both the member and the tubular for maintaining the member in the closed position, and an actuator in keyed engagement with the lock element for biasing the lock element, wherein actuation of the actuator releases the lock element to resiliently spring into engagement with solely one of the member or the tubular for enabling the member to move relative to the tubular to the open position for opening the port.
