If you are really keen to use the motor for lockpicking, try the following.
The Idea is to make a vibrator out of the motor. To do that you have to mount a piece of wood or metal (metal better!) on the axis, so that
the axis DOES NOT go through the center of the mouted piece. The closer the excentric piece to the motor, the less the vibrations but the more powerfull they will be. You could also mount a fan and use it as a kitchen mixer
At the end of the motor you can attach your favourite lockpick with some tape. You could also use the made device for massaging.
