The vault door on Spy Island is a trick because the ceiling is open.
The vault door in the bank on Super Power Island can be reached by jumping on the ledge to the right that has a Copycat clone on it. Then you can reach the one on the light fixture above.
if your in the vault leave to the door on your left and keep going left until you reach the exit door

There are vaults on more than one island. Some are:Spy Island - enter through the ceiling and click the spy to untie himSuper Power Island - you chase the Copycat clones downstairs and upstairs, including one that is on a light just above the vault door
