Parts:
1 - 5mm ball magnet*
1 - 3mm ball magnet*
2 - 4x10mm cylinder magnet*
Assembly:
Insert the 3mm sphere in the hole at the base of the gate and the 5mm sphere in the hole above the gate. The magnets need to be able to rotate freely. Insert the cylinder magnet into the carabiner gate. It needs to be able to slide freely without friction. When the gate is closed, the cylinder should slide up to the 5mm ball magnet, locking the carabiner. Touch one end of the other cylinder magnet to the 5mm ball (if it doesn't work, try the other end), it should rotate the ball and open the gate. Insert the last cylinder magnet into the key, orienting it correctly so it will unlock the carabiner.
