Things You'll Need

Instructions

1

Remove the cover plates, or roses, from around your doorknob handles. They are typically not fastened, so you will simply need to slide them away from the door using your hands. If they are on too tightly, try twisting them to loosen them up.
2

Unscrew the two screws that are holding the lock in place. These will typically be on the inside of your home. You can dispose of these screws once they are removed as your new lock will come with appropriate fasteners.
3

Grasp one doorknob in each hand and slowly pull them apart until they are removed from the door.
4

Take the lock you removed to your local home improvement store and buy a similar Kwikset model. If you are replacing the lockset because you lost your keys or are worried about security, make sure you choose a lock with a different key pattern than the one you currently have. Kwikset makes this easy by stamping an ID number on the lock set itself as well as on the outside of the packages. Choose a lock with a different number than the one you are holding.
5

Remove your lock from the package. Make sure that the side with the keyhole is on the correct side of the door (outside of the home). Slide the two knobs together so that the spindles on one half of the lock connect with the holes on the other half. Push them toward the door until they are flush with the face of the door.
6

Install the two set screws that come with the lock. The location for these screws will be marked on the lock package.
7

Push the cover plates (roses) flush to the door to finish the installation. Not all lock sets will have these plates, so don't worry if yours does not. They are simply for aesthetics.
