How to Replace Door Locks
Your first line of defense is your door lock. It will stop unauthorized entry into your home. Locks may require
upvc replacement door locks due to wear and tear or other events such as moving into a new home or a burglary.
To begin, determine the size of your cylinder using the distance between the adjustment screw and the center of the knob lock cylinder. This measurement will allow you to buy the right lock.
Deadbolt
Installing a deadbolt is ideal way to secure your door from intruders. 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 side and a thumb turn device on the interior. Deadbolts will only work if it is installed correctly.
You will first need to determine whether the door already has a hole that is suitable for a deadbolt, or if you need to bore it out. Mark the location of the hole for the deadbolt on the exterior of the door using the template included with your lock installation set. Then, use your tape measure to determine how high the deadbolt should be. Then, mark this height on the side of the door. You can then use the speed square to draw straight lines across the mark you made for the bolt hole.
Then by using the power drill, drill out the hole until it is on the opposite side of the door. This could take a while. Then, sand down the hole and the edge of the door so that it is smooth. At this stage, it's a great idea to paint or stain your door.
Once the door is ready take off any screws that are visible on the existing deadbolt. This will reveal the front and back assemblies of the deadbolt, and also the bolt inside. Then, unscrew the bolt and
replace door lock it with a brand new one that is compatible with your door hardware. It is necessary to remove the bolt from a setplate. Once this is done then you need to cut out the space for the strike plate on the door frame.
If your strike plate is not in alignment It could be due to the previous installer did not mortise it properly, or an installation of a weatherstripping altered the strike's location. To fix this problem it is necessary to remortise both the strike plate as well as the deadbolt. Close and lock the deadbolt after you have completed this step. Make sure the bolt extends into the strike plate and then test the key to ensure it opens and closes effortlessly.
Knob
When a door knob is damaged it could make your home or business less secure. It could also make opening or closing the door more difficult, which is why it is an ideal idea to replace the knob. It shouldn't take you longer than 30 minutes. Use a screwdriver or pliers to take off any knobs or handles. Be cautious not to scratch other parts of the door.
Before you begin, you'll want to spray WD-40 or some other dry lubricant onto the mechanism of the knob for your door. This will help the new lock move smoothly when you turn it. It's important to use a quality knob and handle that match your current doors to ensure that the lock is operating properly. If you don't have a matching knob you'll need to purchase a new doorknob and latch plate.
Before you begin the replacement process, look over the knob you replaced to determine what screws are that are holding it in place. If there aren't any screws, you can make use of a screwdriver and wedge it between the cover plate and the hidden screws plate and remove it.
After taking the knob off, inspect it for signs of rust and damage. You'll need to clean it off if there are any scratches or dents however you don't need to do anything when the knob is in good shape.
Install the new knob. You must first study the two knobs to make sure that you've selected the right one for the
upvc door locks replacement. You'll want to pick one with an extending rod that is designed to lock with the second knob's rod mechanism. After you've placed the new knob over the hole in the door and then carefully insert it into the latch.
Test the spring by pressing it down repeatedly. The latch should spring back up every time. Next, install the other new knob and interlock it with the rod mechanism on the first knob. Attach the other long screws from the knob's interior through the hole for the cylinder on the doorknob outside and secure it.
Latch
A latch is a metallic piece that extends into the door jamb to secure it shut. The latch is operated via a knob or handle located inside the door, or by a thumb-turn on the exterior. A deadbolt is a device used to secure a latch and stop intruders from breaking through the glass of the door. It also helps protect against accidental or intentional closing by children or animals. A latch can be set with a single cylinder deadbolt or double cylinder deadbolts, according to the security level you prefer.
Installing a latch requires the same steps similar to installing a deadbolt however, there are a few differences. To ensure that the new lock will fit, first measure the setback on the doorjamb using a tape measure. The setback is the distance between the edge of the doorjamb, to the center of the hole that will be used for the latch faceplate. The standard setback is 2 3/8 to 2 3/4 inches. If you have a greater setback, you may have to purchase a more substantial latch from a hardware store or locksmith.
Then, you'll need to make a hole for a latch plate in the edge of the doorjamb. Use a chisel and make the mortise for the latch. Make sure the depth is sufficient for the faceplate to be flush with the doorjamb. Place the strike plate in place to make sure it is positioned correctly.
If the strike is placed too high, the door could be pushed in or pressure applied to it using a crowbar, or tire iron. This could also cause cracks in the doorjamb. To correct this, the strike could be lowered by drilling a new hole into the doorjamb and chiseling out the center of the hole that was previously drilled.
The last step is to mount the new strike plate, which is done by screwing it over the screw holes that are already in place. Then you can use wood putty to cover the old screw holes and the bolt hole that will not be used. After the putty has dried, sand it smooth for an elegant finish.
Strike
An electric strike is the metal piece that holds the latch and deadbolt engage when the door is shut. It is an important part of the overall security of a lock since it keeps the door shut and provides extra resistance to force or kicks applied to the door. If a door comes with an electronic strike, it will be opened by using a key and the control unit that controls its electrical impulses.
Traditionally the installation of an electric strike involved cutting out a portion of the doorjamb in order to remotely remove a cylindrical lock's latchbolt from the pocket within the strike. This modification is not just unattractive, but also exposes the mechanism for the latchbolt and keeper to uninitiated users.
Recently, several electric strike makers have come up with a brand new electric strike dubbed the "No Cut" strike that doesn't require an opening 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 has an internal ramp that raises the latchbolt and keeper when it receives an electrical signal from a reader or controller. The retracting of the keeper as well as latchbolt causes them to rise on the ramp, which locks the door. When the door is shut, the deadbolt remains retracted, and the latchbolt retracts in the keeper.
Installing an electric strike can be an easy process, particularly in the case of
replacing door locks a strike on an existing door. If you are upgrading an access control system to an electric strike, you must ensure that the new system is compatible. It is also necessary to make sure that the strike is properly connected to your access control system and is set up to operate in a fail-safe manner.
Upgrade your strike plates to heavy duty strike plates to prevent unauthorized entry. These plates use four to six three-inch screws instead of the two three-fourth inch screws typically employed in regular strikes. These screws are longer, making it more difficult for anyone to break the frame and reach inside to turn the thumb turn part of a single deadbolt cylinder.
