How to replace door lock (dig this) composite door lock replacement Locks
Door locks are the first security measure against unauthorized access to your home. Locks might require replacement due to signs of wear and tear or other events like 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 want to ensure your door is secure against burglars, it's a good idea to install deadbolts. When the bolt is extended into the strike plate of the doorframe it makes it harder for an intruder to break through the door. A single cylinder deadbolt can be activated with an exterior key on the side and a thumb turn device on the interior. Deadbolts are only effective only if it's correctly installed however.
It is first necessary to determine if the door has a hole that is suitable for a deadbolt or if you have to drill it out. With the template included with the 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 needs to be. Then, mark this height on the edge of the door. You can then use a speed square to draw straight lines across the mark you made for the bolt hole.
Then, use a power drill to bore out this area until the hole is on the opposite side of the door. This could take a bit of time. Sand the hole and the edge of the door to smooth it. It's also recommended to stain or paint the door at this point.
When the door is open remove any screws that are visible on the existing deadbolt. This will reveal the back and front assemblies of the deadbolt, as well as the bolt inside. Remove the bolt and replace lock on upvc door it by the new bolt to match your door hardware. You will need to unscrew the bolt from a setplate. Once this is done, you will need to cut out the space for the strike plate that is on the door frame.
If your strike plate is out of alignment it could be because the previous installer failed to mortise it properly, or an installation of a weatherstripping altered the strike position. You will need to re-mortise the strikeplate and possibly even the deadbolt to fix the issue. Close and lock the deadbolt after you have completed this step. Test the deadbolt by closing it and locking it once the bolt has been extended into the strike plate.
Knob
It can make your home or business less secure if the door knob is worn. It can make opening or closing the door more difficult, which is why it's an ideal idea to replace the knob. It shouldn't take longer than 30 minutes. Use a screwdriver or pliers to take off any knobs or handles. Be cautious not to damage 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 help the new lock slide smoothly as you turn it. It's important to use an excellent knob and handle that matches your doors currently in order to ensure proper operation. If there's no match then you'll have to purchase a new doorknob and latch plate.
Before you begin the replacement process, take a look at the knob that was previously used to see what screws are keeping 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 then remove it.
After taking the knob off, inspect it for evidence of damage or rust. You'll have to scrub it off if there are any marks or dents however, you shouldn't need to do anything if the knob is in good shape.
It's time to install the new knob. Begin by examining the knobs you've chosen to ensure that 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. Once you've put the new knob in the door's hole, carefully insert it into the latch.
Test the spring by pressing it repeatedly. The latch should spring up every time. Then, put in the new knob and lock it to the rod mechanism of the first knob. Attach the other long screws from the interior knob through the cylinder hole on the doorknob on the outside and secure it.
Latch
A latch is a piece of metal that extends into the doorjamb to secure it closed. It is operated by a knob or handle on the interior side of the door, or a thumb turn on the outside side of the door. A latch can be secured by deadbolts to prevent intruders from breaking in through the glass of the door. It can also protect against accidental or intentional closing by children or animals. A latch can be installed using one cylinder deadbolt or a double cylinder deadbolt, according to the security level you prefer.
Installing a deadbolt is the same as installing a latch, but there are some differences. First, measure the setback of the doorjamb with an instrument to make sure the new lock will fit. The setback is the distance from the edge of the doorjamb to the middle of the hole that will be used for the faceplate of the latch. Standard setbacks are 2 3/8 to 2. 3/4 inches. If your setback is higher it is possible to purchase a latch that is longer from a hardware or locksmith store.
Next, make a hole for the latch plate into the edge of the doorjamb. Utilize a chisel to smooth out the latch mortise, making sure it's deep enough for the faceplate of the new latch to be flush with the doorjamb. Tape the strikeplate to the doorjamb to ensure it is positioned correctly.
If the strike is positioned too high, the door may be kicked in or pressure imposed on it using a crowbar or tire iron. This could also cause cracks in the doorjamb. This can be corrected by drilling a new hole through the doorjamb, and cutting the core from the hole that was previously made.
The last step is to install the new strike plate, which can be done by screwing it over the screw holes that are already in place. Use wood putty then to fill in any old bolt holes or screw holes that won't be used. After the putty has dried, sand it to an even finish.
Strike
The piece of metal that is inserted between the deadbolt and latch when the door is shut is an electric strike. It is a vital part of the lock's security, as it prevents the door from opening and provides an additional level of resistance to force or kick. If a door comes with an electronic strike, it can be opened only by a key and the control unit that regulates the electrical impulses.
In the past, installing an electronic strike required cutting a portion of a doorjamb to remove the latchbolt on a cylindrical lock from the pocket that is inside the strike. This change can be a drawback in terms of the aesthetics of an opening as well as exposing the keeper mechanism and latchbolt to unauthorized users.
Recently, a variety of electric strike manufacturers have come up with a "No Cut" type of strike that doesn't require a cutout to operate. The strikes use a unique design that allows the latchbolt and keeper to slide into the strike pocket without damaging the doorjamb faceplate.
The strike has an internal ramp that raises the keeper and latchbolt when it receives an electrical signal from a controller or reader. The keeper and latchbolt are pushed up the ramp due to retract. When the door is closed, the deadbolt stays retracted and the latchbolt retracts into the keeper.
Installing an electronic strike is a straightforward procedure, particularly if you're replacing upvc door lock and handle an existing strike. If you're planning to upgrade an existing access control system to an electric strike, you must ensure that your new system is compatible. Also, you must make sure that the strike is wired to your access control system and that it is set up for fail-safe operation.
Upgrade your strike plates to high duty strike plates to prevent the entry of unauthorized persons. These plates are fitted with four to six screws of three inches instead of the two three-fourth inch screws that are typically employed in regular strikes. These longer screws make breaking the frame to reach the thumb turn piece on a single cylinder deadbolt more difficult.
