How to Change Door Locks

Date:Jul 17, 2019

Changing a door lock is necessary when you move into a new home, get a new roommate, or experience a burglary. It can also be a quick, easy way to switch up your door’s look. If you love your existing knobs and don’t want to replace the entire set, you can simply rekey the lock with a kit labelled for its brand. Have no fear if your knob lock is fine, but your deadbolt needs to be replaced. Changing a deadbolt is even easier than switching out your knobs.

1. Replacing a Knob Lock

Remove the screws from the old lock on the inside of the door. 

Use a lock of the same brand that fits your door. 

Remove the screws that secure the latch at the edge of the door. 

Wrap the cardboard template around the door edge.

Put the new latch into place.
Put the door lock together.

2. Rekeying a Lock

Purchase a kit labelled for your lock’s brand. 

Remove the exterior door knob. 

Pop the the cylinder out of the back of the knob. 

Remove the cylinder retainer ring.

Slide the cylinder plug out of the cylinder housing. 

Remove the old pins from the cylinder plug. 

Insert the new pins to match the code in the instructions.

Reassemble the lock. 

3. Changing a Deadbolt

Remove the old deadbolt faceplates. 

Remove the set plate and bolt.

Rekey the old deadbolt or take it to a locksmith.
