In one sentence, describe what the following article is about:

Most privacy door knobs, also known as "bed and bath" door knobs, either have a pushbutton or twisting lock mechanism on the inside Doorknob.  The outside Doorknob will have a small round hole in the center that is intended to allow for emergency access.    If possible, ascertain which kind of lock mechanism (push button or twisting) you are dealing with. If the outside Doorknob has a keyhole instead of a hole, you will need to proceed to the method for picking a locked entry door. You need to find a long, thin object that is small enough to fit into the hole, but sturdy enough to put pressure on the locking mechanism.  Ideal choices include a small screwdriver or hex wrench, a hair pin, or a heavy-duty paperclip.  You can even use a bamboo skewer from the kitchen, or a cotton swab with the fluff removed from one end.  If using a hair pin or paper clip, first bend it open so you have a long, straight bit of metal. If you are having trouble finding a suitable object, get creative. Open up a ball-point pen and use the ink cartridge, or check the bottom of your purse for a toothpick.  You can almost always find something that will work!
