Remove a Knobset Lock

What is a knob-set lock ? It could also be known as an entrance set or entrance lockset. There are two types, one has exposed screws on the inside of the door and the other we will talk about has concealed screws.

Steps

 * 1) Looking around the knob from the interior side of the door you will notice a small hole, under that hole is a small retaining button that holds the inside knob on, if you cannot see the little button try turning the knob backwards and forwards until you find the buttons centre.
 * 2) With a small nail or piece of wire push into the hole and depress the button.
 * 3) Holding in the button, pull the knob back towards you and slowly pull out your piece of wire.
 * 4) Remove the face plate by carefully prying it off with a flat blade screw driver inserted into the slot on the edge of the face plate, sometimes it helps to turn the face plate a little while you do this as it may have a hinge point on its opposite side.
 * 5) With the face plate removed you can now see the two screws that remove the lock.

Tips

 * If the knobset has been painted around try running a blade around the edge of the face plate to break the seal.

Warnings

 * Common problems with removing these locks is people slicing their hand open by pushing too hard with the screwdriver and slipping !
 * There are a few styles of mainly commercial grade locks where the inside rosette unscrews off, instead of being held on with screws. A good rule of thumb is that if the inside rose is held on with screws (beneath the plate) you will see a small "u" shaped piece of wire material coming through the hole of the rosette, close to where the knob slid off. If the whole rosette unscrews you will see a small hole somewhere along the outside circumference of it, right where it touches the door surface. There are several different versions of specialty wrenches that allow you to remove the rosette.
