A tool includes a locator 200 having a center aligned with a rotor axis 106 when disposed over the valve 100. The locator is approximately perpendicular with the rotor axis. An adjustor 300 is disposed in the locator. The adjustor fits within the wall and has a magnet 304 having a magnetic axis to unlock the rotor. An adjustable outer wall has a first position dimension 312 permitting the adjustor to rotate about the center of the locator and aligning the magnetic axis with the center. The adjustable outer wall has a second position dimension 316 less than the first dimension and the first position dimension. The adjustor can move lateral, rotational, and orbital in the locator misaligning the magnetic axis with the center. Misaligning the magnetic and rotor axes unlocks the rotors and the magnet maintains the unlocked state even when the axes are misaligned.
