Push button Locks

• 1). Unfold a paper clip so that the end is straight.
  
  
• 2). Stick the straight end of the paper clip into the hole on the outside of the doorknob.
  
  
• 3). Push the paper clip until a popping sound is heard. A button inside the knob will push on a rod or lance that pops the lock open.

  Insert the head of the regular flathead screwdriver into the slot on the outer knob. If the turning tab lock has a keyhole on the outside knob, skip to step 3.
  
  
• 2). Turn the screwdriver counterclockwise to turn the tab and open the lock.
  
  
• 3). Stick the tiny flathead screwdriver into the keyhole on the outside knob. There is a slot inside the knob that the screwdriver must fit into. Give the screwdriver a quarter-turn clockwise, which will unlock the door. This may take a few attempts.
