How to De-Core a Kwikset Deadbold Lock

Removing the Core Using a Control Key

• 1

  Insert the control key into the deadbolt lock. A control key is a key that fits your lock but has a notch cut out of the top straight edge, allowing the key to turn in the opposite direction to remove the core.

• 2

  Turn the control key counterclockwise about a quarter of a turn.

• 3

  Pull the key toward you to remove the core from the deadbolt.

Removing the Core Without a Control Key

• 4

  Unscrew the screws attaching the deadbolt to the door using a screwdriver that matches your screws, usually a Phillips-head screwdriver. Pull the deadbolt off the door.

• 5

  Remove the cylinder assembly, the piece with the cylindrical body and long bar sticking out of the back, from the outer casing.

• 6

  Pull the spring, the small metal piece whose curved end is showing below the long bar sticking out of the back, gently out of the assembly using pliers.

• 7

  Insert the end of the spring into the T-shaped slot on the side of the cylinder. Move the spring around until the inside of the cylinder assembly comes loose, releasing the deadbolt core.
