Step 4: Take off the Door Knob
As long as the dead bolt on the door is not in use, you should be able to gain entry by removing the door knob. Most door knobs have the connection or mounting screws concealed, but look closely at the door knob and you will see a tiny pin-sized hole or slot, usually located below or to the side of the door knob. Using a thin piece of metal, like a straightened bobby pin or a paper clip, insert your newly made tool into the hole and apply pressure.
You should feel resistance- keep pushing the metal tool as far into the hole as possible with one hand, while pulling and twisting the door knob with your other hand. Keep up this dance of applying pressure with your make-shift tool and simultaneously pulling and twisting the door knob until you’ve removed the door knob. Now all you have to do is pry off the decorative plate to reveal the lockset. Using a screwdriver (or your bobby pin) pull back on the locking mechanism and the door should unlock.
