What Do You Know About Replace Door Lock?
How to Replace Door Locks
Your first security measure is your door lock. It will prevent unauthorized entry to your home. Locks may need to be replaced because of signs of wear and tear or other circumstances such as moving into a new home or a break-in.
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 appropriate lock.
Deadbolt
Installing a deadbolt is 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 using an exterior key on the side and a thumb turn device on the interior. A deadbolt will only work only if it's correctly installed, though.
The first step is to determine if the door already has a hole for deadbolts, or if it needs to be bored out. Mark the location of the hole for the deadbolt on top of the door using the template included with your lock installation set. Use a 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 that you made to mark the bolt hole.
Then, using the power drill, drill through the hole until it reaches the opposite side of the door. This may take some time. Sand the hole and edge of the door to smooth it. At this moment, it's a good idea also to paint or stain your door.
Remove any screws that are visible from the deadbolt. This will reveal both the rear and front assembly of the deadbolt, as well as its bolt inside. Then unscrew the old bolt and replace it with an alternative bolt that matches the door hardware. You'll need to remove the bolt from the setplate. After that, you'll have to chisel the area on the door frame for the strike plate.
If your strike plate is not in alignment, it could be because the previous installer didn't mortise it properly or that a weatherstripping has changed the strike's position. To correct this issue you'll need to remortise both the strike plate and the deadbolt. Close and lock the deadbolt once you've completed this process. Test the deadbolt by closing and locking it once the bolt has been extended into the strike plate.
Knob
It could make your home or business less secure when the door knob is damaged. It may also make it harder to open or close the door, which is why it's an ideal idea to replace it. It shouldn't take you more than 30 minutes. You can use a screwdriver or pliers to take off the knob or handle Be careful not to damage any of the other components on the door.
Before you begin you'll need to spray WD-40 or another dry lubricant onto the mechanism of the door knob. This will help the lock to move effortlessly when you turn it. It is essential to choose a quality knob and handle that match your current doors to ensure proper operation. If you don't already have a doorknob that is compatible, you will need to buy a replacement.
Before you begin the replacement, take a look at the knob that was previously used to determine what screws are keeping it in place. If there aren't any screws to hold it in place, you can use a screwdriver to insert the cover plate in between the hidden screws plate.
After you have removed the knob examine it for signs of rust and damage. You'll have to scrub it off if there are any marks or dents however you don't need to do anything If the knob is in good working order.
Now it's time to install the new knob. First, examine the two new knobs to ensure you're selecting the correct one for your door. You'll need to choose one that has an extending rod that's designed to lock into the second knob's rod mechanism. Once you've put the new knob in the hole, slide it into the latch.
Thread the latch plate screws down, then test the spring by pushing down repeatedly. The latch should then spring back up every time. Install the second knob and lock it to the rod mechanism of the first knob. Thread the long screws from the interior doorknob into the holes for the cylinder on the outside knob and fix it in place.
Latch
A latch is a piece of metal that extends into the door jamb to keep it shut. It is operated by a handle or knob on the inside of the door or a thumb turn on the exterior side of the door. A latch can be secured by deadbolts to prevent thieves from breaking through the glass. It also offers protection from the accidental or deliberate closing of the door by pets or children. A latch can be installed with single cylinder deadbolts 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, take a measurement of the setback on 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 for the faceplate for the latch. Setbacks for standard latches are 2 3/8 to 2. 3/4 inches. If you have a greater setback, you may have to purchase a longer latch at a hardware store or locksmith.
Then, you'll need to drill a hole for the latch plate at the edge of the doorjamb. Use a chisel and cut the mortise of the latch. Make sure that the depth is enough to allow the faceplate to be flush with the doorjamb. Place the strike plate in the correct position to ensure it's in the right position.
If the strike is too high, you can kick the door in or apply pressure with the tire iron or crowbar. This can cause the doorjamb's to crack. To fix this, the strike could be lowered by drilling another hole into the doorjamb and chiseling out the center of the old hole.
Installing the new strike plate is the last step. upvc door lock replacements can be accomplished by fixing the new plate to the existing screw holes. Use wood putty then to fill in any existing holes for screws or bolts that aren't being used. Once the putty has dried then sand it to a smooth finish.
Strike
An electric strike is the metal piece that holds the latch and deadbolt engage when the door is closed. It is a crucial component of the overall security of a lock because it keeps the door shut and provides extra resistance to force or kicking applied to the door. If a door is fitted with an electronic strike, it will be opened only by keys and the control unit that regulates its electrical impulses.
Traditionally, installing an electric strike involved cutting a small portion of the doorjamb in order to release a cylindrical lock's latchbolt from the pocket of the strike. This modification can be an issue in terms of the appearance of an opening and also exposes the mechanism of the latchbolt and keeper to unintentional users.
Recently, several electric strike manufacturers have created an innovative type of electric strike dubbed the "No Cut" strike that doesn't require an opening in the doorjamb for operation. These strikes use a special design that allows the latchbolt and keeper to slide into the pocket without damaging the faceplate of the doorjamb.
The strike is equipped with an internal ramp that lifts the latchbolt and keeper when it receives an electrical signal from a controller or reader. The retracting of the keeper and latchbolt raises them on the ramp, thereby locking the door. When the door is closed the deadbolt remains in extended and the latchbolt is retracted into the keeper.
Installing an electronic strike is a straightforward process, particularly in the case of replacing an existing strike. If you're upgrading an existing access control system to an electric strike, you must ensure that your new system is compatible. Also, you must ensure that the strike is properly connected to your access control system and is configured to operate in a fail-safe manner.
One method to guard against access by unauthorized persons is to upgrade the strike on your doors to a high-quality strike plate. These plates can be fitted with up to six screws of three inches instead of the usual two screws of three-fourths inches. These longer screws make it more difficult for people to break the frame and then reach inside to turn the piece that turns the thumb of a single cylinder deadbolt.
