Hello,
I am having trouble lockpicking a door in my house than was accidentally locked from the inside. There is a hole on the side of the doorknob but it doesn't seem to have any sort of mechanism in it. I tried using a screwdriver and pushing it in the hole but nothing happened. So my only bet was to pick the lock. I managed to create a rake and a tension wench out of paper clips. I kept raking the pins until the keyhole turned. The keyhole turned 90 clockwise and stopped. I couldn't open the door nor turn the knob. Below is a link to the picture of the keyhole below.
