Who Is Replace Door Lock And Why You Should Care
How to Replace Door Locks
Door locks are the first protection against unauthorised entry into your home. The locks may require replacement due to signs of wear and tear or other circumstances such as moving into a new house or a break-in.
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 enable you to purchase the correct-sized lock.
Deadbolt
If you're looking to ensure that 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 much more difficult for an intruder to break through the door. A single cylinder deadbolt can be activated using a key on the exterior side and a thumb turn piece on the interior. A deadbolt is only effective if it's installed correctly however.
First, you must find out if the door has an existing hole for a deadbolt or if you need to drill it out. Mark the location of the hole for the deadbolt on the exterior of the door using the template included with the lock installation set. Then, use your tape measure to determine how high the deadbolt should be. Mark this high point on the door's edge, and then use the speedsquare to draw a straightline across the mark that you made to mark the bolt hole.
Then, use a drill to drill this spot until the hole reaches the opposite side of the door. This may take a while. Then, sand down the hole and the edge of the door so that it's smooth. At this stage, it's a great idea to stain or paint your door.
Remove any visible screws from the deadbolt. This will reveal both the front and rear assemblies of the deadbolt and its internal bolt. Then, unscrew the bolt and replace it with a new one that is compatible with your door hardware. The bolt is usually attached to a set plate, which you will need to unscrew. After that it is time to cut out the space for the strike plate that is on the door frame.
If your strike plate is misaligned, it's likely because the previous installer didn't mortise it correctly or a weatherstripping popped up and changed the strike's position. It is necessary to re-mortise your strike plate and possibly even the deadbolt to correct this problem. 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 smoothly.
Knob
It could make your business and home less secure if the door knob is damaged. It could make it difficult to open or close the door, which is why it's a good idea to replace the knob. Replacing a knob is a relatively easy DIY project and shouldn't take less than 30 minutes to complete. You can use a screwdriver or pliers to remove the old knob or handle However, be careful not to harm any other parts on the door.
Before starting, you'll want to spray WD-40 or some other dry lubricant onto the mechanism of the door knob. This will help the new lock slide smoothly when you turn it. To ensure that it operates properly it is essential to select the right knob and handle to match your existing doors. If you don't have a doorknob that is compatible then you'll have to buy a replacement.
To begin the replacement process, first examine the old knob or handle to determine what screws are holding it in place. If there aren't any screws, you can use a screwdriver to insert between the cover plate and the hidden screws plate and remove it.
After you've removed the knob that was previously used, look it over for indications of damage or rust. It's important to clean it off if you notice any scratches or dents, but you shouldn't have to do anything major when the knob is in good shape.
Now is the time to put in the new one. First, examine the two new knobs to ensure you're picking out the right one for your door. You'll need to choose one with an extended rod that will interlock with the rod mechanism of the second knob. After you've placed the new knob in the door's hole, carefully place it in the latch.
Test the spring by pressing it repeatedly. The latch should rise each time. Install the second knob, and lock it to the rod mechanism of the first knob. Then, thread the other long screws from the knob's interior through the hole in the cylinder of the doorknob on the outside and secure it.
Latch
A latch is a steel piece that extends out into the doorjamb to secure it shut. The latch can be operated via a knob or handle on the inside of the door, or a thumb-turn on the outside. A deadbolt is a device used to secure a latch and keep burglars from piercing the glass of the door. It also protects against the accidental or deliberate closing of the door by pets or children. It is possible to install the latch using either a single-cylinder or double-cylinder deadbolt, depending on the level you prefer for security.
Installing a latch involves the same steps like installing a deadbolt however, there are a few differences. To make sure that the new lock will work first, you must measure the setback on the doorjamb using a tape measure. The setback is measured from the edge of the doorjamb up to the middle of the hole for the latch plate. The standard setback is 2 3/8 to 2. 3/4 inches. If your setback is higher than that, you might need to purchase a latch that is longer from a locksmith or hardware store.

Use a chisel for chiseling out the latch mortise making sure it's large enough for the faceplate of the new latch to sit in a flush position with the doorjamb. Tape the strike plate in place to ensure that it is positioned correctly.
If the strike is too high, you could kick the door in or apply pressure with a tire iron or crowbar. This could cause the doorjamb's to crack. This can be fixed by drilling a new hole into the doorjamb, and removing the core from the old one.
Installing the new strike plate is the last step. This can be done by screwing the new plate over the screw holes that are already in place. Then you can use wood putty to fill in the screw holes that were previously used and the bolt hole that won't be used. After the putty is dry, sand it to an even finish.
Strike
The metal piece that engages the deadbolt and latch when the door is closed is an electric strike. It is an essential part of the lock's security because it prevents the door from opening, and also provides an additional level of resistance to force or kicking. If a door is equipped with an electronic strike, it will be opened only with an entry key and a control unit that controls its electrical impulses.
Traditionally, installing an electric strike involved cutting out a portion of the doorjamb to remotely release the latchbolt of a circular lock from the pocket within the strike. This modification is not only undesirable, but also exposes the mechanism for the latchbolt and keeper to uninitiated users.
Recently, a number of electric strike manufacturers have created a brand new electric strike, dubbed the "No Cut" strike that doesn't require a cutout in the doorjamb to operate. These strikes utilize a special design that allows the latchbolt and keeper to slide into the strike pocket without marring the doorjamb faceplate.
The strike has an internal ramp which lifts the latchbolt as well as the keeper when it receives the signal of the reader. The latchbolt and keeper are pushed higher up the ramp by the retract. When the door is closed the deadbolt remains retracted, and the latchbolt is retracted into the keeper.
Installing an electric strike can be an easy process, particularly when you are replacing a strike on an existing door. However, if you're upgrading to an electric strike for an access control system, you will be required to ensure that the new system is compatible with the model of lock you've installed. It is also necessary to ensure that the strike is properly connected to your access control system and that it is designed to operate in a fail-safe manner.
Upgrade your strike plates with heavy duty strike plates to prevent the entry of unauthorized persons. These plates are fitted with 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 difficult for people to break the frame and reach inside to turn the thumb turn part of a single cylinder deadbolt.
