How to Remove a Locked Deadbolt

Removing a locked deadbolt is only a problem if you're on the outside looking in, or if you're inside, and the deadbolt requires a key from both the inside and the outside. It is possible to remove it, but only by destroying the cylinder, which requires replacing it. This should only be performed in situations where the key has been lost or when you're planning to replace the entire deadbolt lock entirely.

Things You'll Need

• Small screwdriver Electric drill Metal drilling bit Phillips screwdriver

Instructions

1. 

   Insert a metal-drilling bit into your drill, and drill directly into the keyhole of the lock. You'll have to drill straight in, which will destroy the lock and allow the pins and springs to become disengaged.

2. 

   Insert a small screwdriver into the drilled hole, and rotate back and forth. This will allow the pins and springs to fall out, and allow the cylinder to turn. Repeat drilling until the cylinder is able to turn and you are able to use the screwdriver as a key.

3. 

   Pull the cylinder out, and use a screwdriver to disengage the deadbolt from the locked position.

4. 

   Open the door and remove the screws that hold the deadbolt into place on the inside of the door.

5. 

   Slide the lock out of the door, once you've removed the screws that hold the strike plate into place. If security is an issue, install the new deadbolt right away.

Tips & Warnings

• Don't be afraid of over-drilling when drilling into the cylinder. Plan on buying a new deadbolt if you have go this route.

• Always wear eye protection, because drilling in metal is extremely dangerous.
