Before you begin, note that you will find the sash lock on the operable portion of the window. To start, you are going to want to tilt the sash of your double hung window inward. To do that, find the two sash tilt buttons and press both of them at the same time. Then lower the sash towards you to open. Next, you need to take your flat putty knife and use it to take out the top thumb lock by prying it up and away from the sash. Then, you will take the Phillips head screwdriver and use it to take out the screws from the interior operator lock. After you remove the screws, take out the old sash lock from the panel.
