In this tutorial, the instructor shows us how to open up a door with a screwdriver. For this to work you will need a locked door and a screw driver. You first will need to take the screw driver and push it under the two latches on the side of the door on the lock. Keep pulling back on the latches with the screwdriver until the door pops open, this can take a few minutes or a few seconds depending on the lock strength. This will work on most normal door locks. Be careful because this will leave marks on the wall and a dent in the door.
