how to replace upvc door lock to replace lock on patio door Door Locks

Your first security measure is your door lock. It will prevent unauthorized access to your home. Locks might need to be replaced because of signs of wear and tear or other events such as moving into a new residence or a break-in.

To begin, you must determine your cylinder size by measuring the distance between the adjustment screw and the middle of the cylinder knob. This measurement will allow you to select the appropriate lock.

Deadbolt

If you want to ensure your door is secure from criminals, it's a great idea to install a deadbolt. When the bolt is extended into the strike plate of the doorframe, it makes it harder for an intruder to get through the door. A single-cylinder deadbolt is activated using a key on the exterior and a thumb-turn piece situated inside. A deadbolt is only effective when it's properly installed however.

You will first need to find out if the door has a hole that is suitable for a deadbolt, or if you have to drill it out. Mark the location of the hole for the deadbolt on the exterior of the door using the template that came with your lock installation set. Use a tape measure to determine the height of the deadbolt. Mark this high point on the door's edge. Use a speedsquare to draw a straightline across the mark that you made to mark the bolt hole.

Then using a power drill, bore out the hole until it reaches the opposite side of the door. It may take a while. Then, sand the hole and the edges of the door so that it's smooth. At this stage, it's a great idea to paint or stain your door.

When the door is open take off any screws that are visible on the existing deadbolt. This will reveal the back and front assemblies of the deadbolt, as well as the bolt that is inside. Then, unscrew the bolt and replace door Lock it with a new bolt that matches the door hardware. It is necessary to remove the bolt from a setplate. Once this is done it is time to chisel out the area for the strike plate that is on the door frame.

If your strike plate is not aligned It's likely that the previous installer didn't mortise it correctly or a weatherstripping popped up and changed the strike position. To fix this problem you'll need to remortise the strike plate as well as the deadbolt. Once this is completed, test the deadbolt by closing it and locking it. Make sure that the bolt extends into the strike plate then test the key to make sure it closes and opens easily.

Knob

If the knob on your door is damaged, it can make your home or business less secure. It could make it difficult to open or close the door, making it an ideal idea to replace the knob. It shouldn't take more than 30 minutes. Use a screwdriver or pliers to remove any old knobs or handles. Be careful not to scratch other parts of the door.

Before starting, you'll want toLatch

A latch is a piece of metal that extends into the doorjamb to secure it closed. The latch can be operated by a handle or knob on the interior of the door, or a thumb-turn on the exterior. A deadbolt is a device used to secure a latch and stop burglars from piercing the glass of the door. It also offers protection from the accidental or deliberate closing of the door by children or pets. You can install the latch using either a single-cylinder deadbolt, or a double-cylinder deadbolt, depending on the level you prefer for security.

Installing a deadbolt is exactly the same as installing a latch, however, there are some distinctions. To ensure that the new lock will fit first, measure the setback on the doorjamb using an instrument such as a tape measure. The setback is measured from the edge of doorjamb all the way to the center of hole for the latch plate. A typical setback is 2 3/8 to 2 3/4 inches. If your setback is larger, you may need to purchase a latch that is larger from a hardware or locksmith store.

The next step is to drill an edge bore hole through the doorjamb for the latch plate. Use a chisel for chiseling out the mortise of the latch, making sure it's deep enough for the faceplate of the new latch to sit close to the doorjamb. Place the strikeplate on the floor to ensure it is positioned properly.

If the strike is too high, you can kick the door in or apply pressure with an iron tire or crowbar. This can also cause the doorjamb's to crack. To fix this issue, the strike can be lowered by drilling a new hole into the doorjamb and cutting out the core of the previous hole.

The last step is to put in the new strike plate, which can be done by screwing it over the screw holes that are already in place. Utilize wood putty to fill in any existing holes for screws or bolts that aren't being used. After the putty is dry, sand it to a smooth finish.

Strike

An electric strike is a metal piece that holds the deadbolt and latch are engaged when the door is shut. It is an essential part of the lock's overall safety, as it prevents the door from opening and gives an additional level of resistance to force or kick. If a door is fitted with an electronic strike, it will be opened only with a key and the control unit that regulates its electrical impulses.

Traditionally, installing an electric strike involved cutting out a portion of the doorjamb to release a cylindrical lock's latchbolt from the pocket within the strike. This is an inconvenience when it comes to the aesthetics of an opening as well as exposing the mechanism of the latchbolt and keeper to any unauthorised users.

Recently, several electric strike makers have come up with a brand new electric strike, dubbed the "No Cut" strike that doesn't need cutouts in the doorjamb to operate. These strikes use a special design that allows the latchbolt and keeper to slide into the pocket without causing damage to the faceplate of the doorjamb.

The strike is equipped with an internal ramp that raises the latchbolt as well as the keeper when it receives the signal of an individual reader. The retracting of the keeper and latchbolt pushes them up higher on the ramp, locking the door. When the door is shut the deadbolt remains extended and the latchbolt is retracted into the keeper.

Installing an electric strike is an easy process, particularly when you are replacing an existing strike door. If you're upgrading an existing access control system to an electric strike, it is important to make sure that the new system is compatible. Also, you must ensure that the strike is wired to your access control system and that it is set up for fail-safe operation.

Upgrade your strike plates to heavy duty strike plates to prevent unauthorised entry. The plates utilize four to six screws of three inches instead of the two, three-fourth inch screws typically used in regular strikes. These longer screws make it more difficult for people to break the frame and reach inside to turn the thumb turn part of a single cylinder deadbolt.
