The video suggests pulling down on the lock after completing the combination. If it doesn't open, take a deep breath and try the combination again from the beginning.
That's the only information provided in the source material. Since a "spin lock" is usually understood to be a combination lock, it's important to know the specific combination and the number of spins/directions required for each number to open the lock successfully. This video clip only provides the general advice of "try again" if it doesn't work.
