Door locks are the first security measure against unauthorized access to your home. The signs of wear and tear, and even instances such as moving into a new residence or break-ins, can necessitate the necessity of replacing your lock.
To begin, determine the size of your cylinder by measuring the distance between the adjustment screw and the center of the cylinder knob. This measurement will allow you to purchase the appropriate lock.
Deadbolt
If you want to make sure your door is safe 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 with an exterior key on the side and a thumb turn device on the interior. Deadbolts are only effective when it's properly installed, though.
First, you must find out if the door has an existing hole for a deadbolt, or if you have to drill it. Mark the location of the hole to install the deadbolt on the surface of the door using the template included with your lock installation set. Utilize your tape measure to determine the height of the deadbolt. Mark this height on the door edge and use a speedsquare to draw a straight line across the mark you made for the bolt hole.
Next, use a power drill to bore out this hole until it is on the opposite side of the door. This may take some time. Sand the hole and the edge of the door to make it smooth. At this stage, it's a great idea also to stain or paint your door.
Once the door is ready take off any screws visible on the deadbolt. This will reveal the back and front assemblies of the deadbolt as well as the bolt that is inside. Then unscrew the old bolt and replace lock on patio door it by the new bolt to match the door hardware. You will need to unscrew the bolt from the setplate. After that, you will need to cut out the space for the strike plate on the door frame.
If your strike plate is out of alignment it could be because the previous installer didn't mortise it properly, or a weatherstripping has changed the strike's position. To fix this issue it is necessary to remortise the strike plate and the deadbolt. Close and lock the deadbolt when you've completed this step. Be sure the bolt extends into the strike plate and then test the key to make sure it opens and closes effortlessly.
Knob

It could make it more difficult to open or close the door, which is why it's recommended to replace lock on upvc door door lock (ai-Db.science) the knob. It shouldn't take you more than 30 minutes. Make use of pliers or a screwdriver to take off any knobs or handles. Be careful not to harm other components of the door.
Spray WD-40, or a different dry lubricant on the mechanism of your door knob before you begin. This will allow the new lock move smoothly when you turn it. To ensure that it operates properly it is essential to select the knob and handle that are compatible with your doors. If there's no match you'll need to purchase an additional doorknob and latch plate.
Before you begin replacing a upvc door lock the knob, examine the old knob to determine which screws are keeping it in place. If there are no screws then you can use the screwdriver to wedge the cover plate between the screws plate that is hidden.
After you have removed the knob take it apart and look for indications of damage and rust. You'll need to clean it off if there are any scratches or dents however you don't need to do anything major when the knob is in good working order.
Now is the time to put in the new knob. You must first study the two knobs to make sure that you are choosing the correct one for your door. You'll need to choose one that has an extending rod designed to interlock with the rod mechanism of the second knob. Once you've put the new knob in the hole in the door carefully insert it into the latch.
Test the spring by pressing it down repeatedly. The latch should then spring back up each time. Install the second knob and secure it to the rod mechanism of the first knob. Thread in the other long screws from the interior knob through the hole for the cylinder on the exterior doorknob and secure it.
Latch
A latch is a piece metal that extends through the door jamb to keep it shut. It is operated by a knob or handle on the interior side of the door or a thumb turn on the exterior side of the door. The latch can be secured using deadbolts to prevent intruders from breaking in through the glass. It can also protect against the accidental or deliberate closing by children or animals. A latch can be installed with single cylinder deadbolts or double cylinder deadbolts, depending on the security level you prefer.
Installing a latch follows the same steps like installing a deadbolt however there are some differences. To make sure that the new lock is compatible first, determine the setback of the doorjamb with a tape measure. The setback is measured from the edge of doorjamb all the way to the center of hole for the latch plate. Setbacks for standard latches are 2 3/8 to 2. 3/4 inches. If you have a higher setback, you might need to purchase a longer latch at a hardware store or locksmith.
Next, drill a hole for the latch plate into the doorjamb's edge. Use a chisel and chisel the latch mortise. Make sure the hole's depth is enough for the faceplate to be in line with the doorjamb. Place the strikeplate on the floor to ensure it is positioned correctly.
If the strike is too high, you could knock the door down or apply pressure using an iron tire or crowbar. This could cause the doorjamb's to crack. To correct this, the strike could be lowered by drilling a new hole into the doorjamb and cutting out the core of the previous hole.
The final step is to install the new strike plate which is done by screwing it over the screw holes that are already in place. Then, use wood putty to cover the old screw holes and the bolt hole that will not be used. Once the putty is dry then sand it to a smooth finish for professional results.
Strike
The metal piece that engages the latch and deadbolt when the door is closed is an electric strike. It is a vital part of the lock's overall safety, as it prevents the door from opening, and also provides additional resistance to force or kicking. If a door is fitted with an electronic strike, it will be opened by using keys and the control unit that regulates its electrical impulses.
In the past, installing an electronic strike required cutting off a part of a doorjamb in order to remove the latchbolt on a cylindrical lock from the pocket that is inside the strike. This modification is not only ugly however, it also exposes the latchbolt mechanism and keeper to uninitiated users.
Recently, a variety of electric strike manufacturers have come up with a "No Cut" type of strike that does not require a cutout for operation. They use a specific design that allows the latchbolt and keeper to slide into the pocket without damaging the doorjamb's faceplate.
The strike has an internal ramp that lifts the latchbolt and keeper whenever it receives an electrical signal from a reader or controller. The latchbolt and keeper are pushed up the ramp by the retraction. When the door is shut, the deadbolt remains in place and the latchbolt is retracted into the keeper.
Installing an electronic strike is a simple procedure, especially when you're replacing an older strike. If you're planning to upgrade an existing access control system to an electric strike, you need to make sure that the new system is compatible. It is also necessary to ensure that the strike is properly connected to your access control system and is designed to operate in a fail-safe manner.
One way to safeguard against unauthorized access is to upgrade the strike on your doors to a robust strike plate. These plates use up to six screws of three inches instead of the standard two screws of three-fourths of an inch. These longer screws make it more difficult for people to break the frame and reach inside to turn the thumb turn piece of a single deadbolt cylinder.
