This guide helps users successfully remove and replace a window sash lock with minimal effort. Some tips to follow for this guides are:

When removing the lock, keep the lock in a half-locked neutral position if possible. This position allows the user to easily access both screws that need to be removed.

When removing the lock keeper, keep pressure on the keeper when removing the last screw as the keeper will fall off the window when the screws are removed. This tip is mainly for those concerned with loosing old pieces, or for those with small children/pets that may get a hold of fallen pieces.
