How to Replace Door Locks
The first line of defense is your door lock. It can stop unauthorised entry into your home. The signs of wear and tear, as well as instances like moving into a new house or burglaries, may trigger the need to replace your lock.
To begin, you must determine the size of your cylinder by measuring the distance between the adjustment screw and the middle of the cylinder knob. This measurement will allow you to purchase the correct-sized lock.
Deadbolt
Installing a deadbolt can be a excellent way to protect your door against intruders. When the bolt is extended into the strike plate of the doorframe, it makes it much more difficult for an intruder through the door. A single cylinder deadbolt is activated with keys on the exterior side and a thumb turn device on the interior. Deadbolts will only work only if it is correctly installed.
It is first necessary to find out if the door has an existing hole for a deadbolt, or if you have to bore it out. With the template included with your lock installation kit, mark the spot of the deadbolt's hole on the door's surface. Then, use the tape measure to determine how high the deadbolt should be. Mark this high point on the door's edge. Use a speedsquare to draw a straightline across the mark that you made for the bolthole.
Then, using a power drill, bore out the hole until it is on the opposite side of the door. This may take some time. Then, sand the hole and the edges of the door so that it is smooth. At this stage, it's a great idea to paint or stain your door.
When the door is in place remove any screws visible on the deadbolt. This will reveal the front and rear assemblies of the deadbolt, as well as its internal bolt. Remove the bolt and replace it with the new bolt to match your door hardware. The bolt is typically attached to a set plate, which you will need to unbolt. Then, you'll need to chisel the surface of the door frame to accommodate the strike plate.
If your strike plate is out of alignment It could be due to the previous installer failed to mortise it properly, or an installation of a weatherstripping altered the strike's position. It is necessary to re-mortise the strike plate and perhaps even the deadbolt to fix this issue. Once you have completed this Test the deadbolt by closing and locking it. Be sure the bolt is extending into the strike plate and then test the key to make sure it is able to open and close effortlessly.
Knob
It can make your home and business less secure if the door knob is damaged. It can also make opening or closing the door more difficult, which is why it is an ideal idea to replace it. It shouldn't take longer than 30 minutes. Use pliers or a screwdriver to remove any old knobs or handles. Be cautious not to damage the other components of the door.
Before starting, you'll want to spray WD-40 or another dry lubricant onto the mechanism of the knob on your door. This will let the lock to move effortlessly as you turn it. It's essential to select the best knob and handle that is compatible with the doors you currently have to ensure proper operation. If you don't already have a doorknob that matches then you'll have to purchase a new one.
Before you begin the replacement, take a look at the knob that was previously used to determine which screws are holding it in place. If there aren't screws, you can use the screwdriver to secure the cover plate in between the screws plate hidden behind it.
Once you've removed the old knob, examine it for signs of damage or rust. If repairmywindowsanddoors.co.uk shows any scratches or marks then you'll need to clean it. Otherwise it shouldn't require any major work.
It's time to install the new knob. Begin by examining the two new knobs to ensure you're selecting the correct one for your door. You'll want to pick one that has an extending rod that's designed to lock into the rod mechanism of the second knob. After you've placed the new knob in the hole and then put it in the latch.
Thread the latch plate screws down and test the spring by pushing down several times. The latch should pop up every time. Then, put in the new knob and lock it with the rod mechanism on the previous knob. Attach the other long screws from the knob's interior through the hole for the cylinder on the exterior doorknob and lock it in place.
Latch
A latch is a metal piece that extends into the doorjamb in order to hold it closed. It is operated by a handle or knob on the inside of the door or a thumb turn on the outside side of the door. A deadbolt is a device used to secure a latch and stop intruders from breaking through the glass of the door. It also provides protection from the accidental or deliberate closing of the door by children or pets. A latch can be installed with one cylinder deadbolt or double cylinder deadbolts, according to the security level you prefer.
Installing a deadbolt is the same as installing a latch, but there are some differences. To ensure that the new lock will fit first, you must take a measurement of the setback on the doorjamb with 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. A standard setback is 2 3/8 to 2 3/4 inches. If you have a higher setback, you might need to purchase a more substantial latch from a hardware shop or locksmith.
The next step is to drill an edge bore hole through the doorjamb to accommodate the latch plate. Utilize a chisel to smooth out the latch mortise and ensure it's deep enough for the faceplate of the new latch to sit in a flush position with the doorjamb. Tape the strikeplate in place to ensure it is positioned properly.
If the strike is too high, you could kick the door in or apply pressure using a tire iron or crowbar. This can also cause the doorjamb to crack. To correct this issue, the strike can be lowered by drilling a new hole through the doorjamb, and then chiseling out the core of the hole that was previously drilled.
The last step is to mount the new strike plate, which can be accomplished by screwing it over the existing screw holes. Then apply wood putty to cover the holes from the previous screws and the bolt hole that will not be used. After the putty has dried you can sand it until it has a smooth finish.
Strike
The piece of metal that is inserted between the latch and deadbolt when the door is closed is an electric strike. It is a crucial component of a lock's overall security, because it helps keep the door shut and also provides additional resistance to force or kicking applied to the door. If a door comes with an electronic strike, it can be opened only with an entry key and a control unit that controls its electrical impulses.
Traditionally the installation of an electric strike involved cutting a small portion of the doorjamb in order to remotely remove the latchbolt of a cylindrical lock from the pocket in the strike. This change can be an inconvenience in terms of the appearance of an opening as well as exposing the latchbolt and keeper mechanism to unintentional 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. These strikes have a unique design that allows the keeper and latchbolt to slide into the strike pocket without marring the doorjamb faceplate.
The strike has an internal ramp which lifts the latchbolt and keeper whenever it receives the signal of a reader. The keeper and latchbolt are pushed higher up the ramp due to retract. When the door is closed the deadbolt remains retracted and the latchbolt retracts into the keeper.
Installing an electronic strike is a straightforward process, particularly when you're replacing an older strike. If you are upgrading an access control system to an electric strike, you must ensure that your new system is compatible. It is also necessary to make sure that the strike is properly connected to your access-control system and is configured to operate in a fail-safe way.
One way to protect against unauthorized access is to upgrade the strike on your doors to a robust strike plate. These plates are fitted with four to six screws of three inches instead of the two three-fourth inch screws that are typically used in standard strikes. These screws are longer and make breaking the frame to reach the thumb turn piece on a single deadbolt for a cylinder more difficult.
