Door Lock Cylinder Replacement

Sometimes the key sticks when the cylinder pins are worn, or the keys are worn themselves. Or you have a broken cylinder or just an old school type of door cylinder and interested in upgrading your cylinder to a high-security anti-snap, anti-pick door cylinder. It is highly recommended that the door cylinder be replaced in order to restore the integrity of your home or business security.

Door cylinders are highly exposed to snapping when they are significantly exposed to the exterior part of the automatic door repair. Burglars can easily force the exposed part of the door cylinder to high pressure causing it to snap at the middle section. This exposes your door to insecurity and, therefore, break-ins. However, because you lock doors from inside, an exposed inside section of a door cylinder is not a security threat at all to your property. The door cylinder replacement process or door handle repair is a do it yourself activity that takes a very short time.

When replacing a door cylinder, you need a few tools such as set square, screws, and screwdrivers as well as a new door cylinder, and follow the steps below to replace the cylinder within the shortest time.

Measure the door width

Using a set square or tape, measure the width of the door to establish the length of the most suitable door cylinder to be replaced. You can also use pencil marks on the old door cylinder and transfer the cylinder together with the marks to your local store in order to buy an appropriate cylinder with the length marked on the old one. Getting a shorter cylinder that fits properly on the door width without protruding to the exterior part of the door will secure the cylinder from cylinder snaps caused by burglars or key sticks.

Unscrew the old door cylinder and remove it

Using screwdrivers, remove the screws on the door, attaching the door break-in repair or door lock to the door cylinder. The screw holds the door cylinder in place to avoid cylinder picks by thieves or trespassers. If your door cylinder is picked, your property is highly exposed to insecurity as the door will not be locked without the cylinder on the lock. Once you have removed the screws, insert the key into the cylinder and turn it to the 2 o’clock position. At this position, pull the key out, and it will come with the door cylinder.

Replace the cylinder

With the appropriate size and brand of a door cylinder you have acquired, insert the cylinder key to its position and turn it to the 2 o’clock position. Insert the cylinder into the door and turn the key. Make sure you can see through the screw hole. Screw up the cylinder using the screw you assembled earlier.
