The first line of defense is your door lock. It will stop unauthorized entry into your home. Locks might require replacement because of signs of wear and tear or other circumstances like moving into a new residence or a burglary.
You can determine the size of your cylinder by measuring the distance from the center of the knoblock cylinder to the adjustment screw. This measurement will assist you buy the lock that is right for you.
Deadbolt
Installing a deadbolt can be a excellent way to protect your door from burglars. The bolt extends into the strike plate on the doorframe when locked, making it more difficult for a burglar to gain entry through the door. A single-cylinder deadbolt is activated by a key located on the exterior and the thumb-turn mechanism located on the interior. door lock replacement repairmywindowsanddoors will only work when it is properly installed.
The first step is to determine if the door has a hole for a deadbolt or if it needs to be bored out. Mark the location of the hole to install the deadbolt on the surface 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 measurement on the door's edge, and then use a speedsquare to draw a straightline across the mark you made for the bolthole.
Then by using the power drill, drill through the hole until it is on the opposite side of the door. This may take some time. Then, sand the hole and along the edge of the door until it's smooth. At this moment, it's a good idea to paint or stain your door.
Remove any screws that are visible from the deadbolt. This will reveal the front and back assemblies of the deadbolt and also the bolt inside. Then, remove the bolt and replace it with a brand new one that matches your door hardware. The bolt is often connected to a setplate which you'll have to remove. After that, you'll have to chisel the door frame for the strike plate.
If your strike plate is not aligned it's likely that the previous installer didn't correctly mortise it or a weatherstripping came along and changed the strike position. You will need to re-mortise the strike plate and perhaps even the deadbolt to fix this issue. Close and lock the deadbolt after you've completed this process. Make sure that the bolt is extending into the strike plate and then test the key to ensure it closes and opens easily.
Knob
If the knob on your door is worn out it could make your business or home less secure. It could make it difficult to open or close the door, so it's an ideal idea to replace it. It shouldn't take you more than 30 minutes. Make use of pliers or a screwdriver to remove any knobs or handles. Be cautious not to damage the 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 lock to move effortlessly as you turn it. To ensure that it operates properly, it's important to choose a knob and handle that are compatible with your doors. If you don't have a matching doorknob, you will need to purchase a replacement.
Before you begin the replacement process, examine the old knob to see what screws are that are holding it in place. If there aren't any screws you can use a screwdriver to wedge between the cover plate and the hidden screws plate and pop it off.
Once you've removed the old knob, examine it for signs of damage or rust. If the knob has any scratches or marks, you'll have to clean it. Otherwise it shouldn't need any major work.
It's time to install the new knob. It is important to first look over the two knobs to make sure that you are choosing the correct one for your door. You should select one with an extending rod that's designed to lock into the rod mechanism on the second knob. Once you've positioned the new knob in the door's hole carefully slide it into the latch.
Test the spring by pressing down on it repeatedly. The latch should spring back up every time. Next, install the other new knob and interlock it to the rod mechanism of the first knob. Thread the long screws of the interior doorknob into the holes for cylinders on the exterior knob and fix it in place.
Latch
A latch is a piece metal that extends into the doorjamb to hold it shut. The latch is operated via a knob or handle located inside the door, or a thumb-turn on the exterior. Deadbolts can be used to secure a latch and keep intruders from breaking through the glass of the door. It also protects against accidental or intentional closing of the door by pets or children. A latch can be set with a single cylinder deadbolt or double cylinder deadbolts according to the security level you prefer.
Installing a deadbolt can be the same as installing a latch but there are some differences. To make sure that the new lock will work, first determine the setback of the doorjamb using an instrument such as a tape measure. The setback is the distance from the edge of the doorjamb to the middle of the hole that will be used for the faceplate for the latch. Standard setbacks are 2 3/8 to 2. 3/4 inches. If you have a larger setback, you may need to purchase a larger latch from a hardware store or locksmith.
Next, drill a hole for the latch plate at the edge of the doorjamb. Use a chisel to chisel out the mortise for the latch and ensure it's deep enough to allow the faceplate of the new latch to sit in a flush position with the doorjamb. Tape the strikeplate to the doorjamb to ensure it is positioned correctly.
If the strike is positioned too high, the door can be pushed into or pressure applied to it using a crowbar, or tire iron. This can cause the doorjamb to break. This can be corrected by drilling a new hole in the doorjamb and then cutting the core from the previous one.
Installing the new strike plate is the last step. This can be accomplished by screwing the new plate into the existing screw holes. Then, use wood putty to cover the old screw holes and the bolt hole that will not be used. When the putty is dry, sand it smooth for professional results.
Strike
An electric strike is the metallic piece where the deadbolt and latch are engaged when the door is shut. It is an essential part of the lock's overall security because it prevents the door from opening, and also provides an additional barrier to force or kick. If a door is equipped with an electronic strike, it can be opened only with a key and the control unit that regulates its electrical impulses.
In the past, installing an electronic strike was as simple as cutting a portion of a doorjamb, which would let the latchbolt of a cylindrical lock from the pocket within the strike. This modification is not only ugly, but also exposes the mechanism of the latchbolt and keeper to uninitiated users.
Recently, a number of electric strike manufacturers have created a "No Cut" type of strike that does not require a cutout for operation. The strikes have a unique design that allows the latchbolt and keeper to slide into the pocket without causing damage to the doorjamb's faceplate.
The strike is equipped with an internal ramp that lifts the latchbolt and keeper when it receives an electrical signal from a reader or controller. The keeper and latchbolt are lifted higher on the ramp thanks to the retraction. When the door is closed the deadbolt is retracted and the latchbolt retracts into the keeper.
Installing an electric strike is an easy task, especially in the case of replacing an existing strike door. If, however, you are upgrading to an electric strike to use with an access control system, you will be required to ensure that the new system is compatible with the model of lock you've chosen to install. It is also necessary to make sure that the strike is properly wired to your access control system and that it is designed to operate in a fail-safe manner.
One way to protect against unauthorized access is to upgrade the strike on your doors to a high-quality strike plate. The plates are made of up to six screws of three inches instead of the standard two screws of three-fourths of an inch. These screws are longer, making it more difficult for someone to break the frame and reach inside to turn the thumb turn piece of a single cylinder deadbolt.
