7 Secrets About Replace Door Lock That No One Will Tell You
How to Replace Door Locks
The first line of defense is your door lock. It will prevent unauthorized access to your home. Locks might require replacement due to signs of wear and tear, or other situations like moving into a new home 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 allow you to buy the right lock.
Deadbolt
Installing a deadbolt is excellent way to protect your door from burglars. The bolt extends into the strike plate that is on the doorframe when it is locked, making it more difficult for burglars to gain entry through the door. A single-cylinder deadbolt is activated by a key located on the exterior, and the thumb-turn mechanism situated inside. Deadbolts are only effective when it's properly installed however.
It is first necessary to find out if the door has an existing hole for a deadbolt, or if you need to bore it out. Mark the position of the hole for the deadbolt on top of the door using the template that came with the lock installation set. Use your tape measure to determine the height of the deadbolt. Mark this height on the door edge. Use speedsquares to draw a straight line across the mark that you made to mark the bolt hole.
Then, using an electric drill, bore out the hole until it reaches the opposite side of the door. This could take a bit of time. Then, sand down the hole and the edge of the door until it's smooth. It's also a good idea to stain or paint the door at this point.
Remove any visible screws from the deadbolt. This will reveal both the rear and front assembly of the deadbolt and its internal bolt. Remove the bolt and replace it by the new bolt to match your door hardware. It is necessary to remove the bolt from the setplate. After that, you'll have to chisel the door frame for the strike plate.
If your strike plate is misaligned, it's likely because the previous installer didn't correctly mortise it or a weatherstripping was installed and altered the strike position. It is necessary to re-mortise your strike plate and perhaps even the deadbolt to fix the issue. Once you have completed this check the deadbolt by closing it and locking it. Be sure the bolt is extending into the strike plate, and then test the key to ensure it is able to open and close smoothly.
Knob
It could make your business and home less secure if the door knob is worn. It could also make opening or closing the door more difficult, so it's an ideal idea to replace it. Replacing a knob is a relatively simple DIY project that shouldn't take less than 30 minutes to complete. You can use a screwdriver and pliers to remove the knob or handle However, be careful not to harm any of the other components on the door.
Before starting you'll need to spray WD-40 or some other dry lubricant on the mechanism of the knob on your door. This will allow the new lock slide effortlessly as you turn it. It is essential to choose an excellent knob and handle that match your current doors to ensure that the lock is operating properly. If you don't already have a doorknob that matches, you will need to purchase a replacement.
Before you begin the replacement process, examine the old knob to determine what screws are holding it in place. If there aren't any screws, you can use the screwdriver to secure the cover plate into the screws plate hidden behind it.
Once you've removed the old knob, examine it for signs of rust or damage. If the knob has any marks or scratches, you'll have clean it. Otherwise, replacement door lock require any major work.
Install the new knob. Before you do that, look over the knobs you've chosen to ensure you're picking out the right one for your door. You'll need to choose one with an extended rod designed to interlock with the rod mechanism on the second knob. Once you've put the new knob into the hole and then put it in the latch.
Test the spring by pressing down on it repeatedly. The latch should rise each time. Then, put in the new knob and connect it to the rod mechanism on the first knob. Then, thread the other long screws from the knob's interior through the cylinder hole on the doorknob outside and lock it in place.
Latch
A latch is a metal piece that extends into the door jamb in order to hold it closed. The latch is operated via a knob or handle located inside the door, or a thumb-turn on the exterior. The latch can be secured with deadbolts to prevent thieves from breaking through the glass. 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 deadbolt or double-cylinder deadbolt depending on your preferred level of security.
Installing a latch follows the same steps like installing a deadbolt but there are a few differences. To ensure 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 between the edge of the doorjamb to the middle of the hole that will be used for the faceplate for the latch. A standard setback is 2 3/8 to 2 3/4 inches. If you have a larger setback, you may have to purchase a more substantial latch from a hardware store or locksmith.
The next step is to drill an edge bore hole into the doorjamb to accommodate the latch plate. Use a chisel for chiseling 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. Place the strike plate in the correct position to ensure it's in the right position.
If the strike is too high, you can knock the door down or apply pressure with a tire iron or crowbar. This could cause the doorjamb's to crack. This can be repaired by drilling a new hole into the doorjamb and then chiseling the core out of the previous one.
Installing the new strike plate is the last step. This can be done by fixing the new plate to the screw holes that are already in place. Use wood putty then to fill in any old holes for screws or bolts that aren't being used. When the putty is dry then sand it to a smooth finish for professional results.
Strike
The piece of metal that is inserted between the deadbolt and latch when the door is closed is an electric strike. It is an essential component of the lock's overall safety, as it prevents the door from opening and provides an additional barrier to force or kicking. If a door has been equipped with an electric strike, it will only be opened using a key or the control unit which controls its electrical impulses.
In the past, installing an electronic strike was as simple as cutting a piece of a doorjamb to let the latchbolt of a cylindrical lock from the pocket that is inside the strike. This is an inconvenience in terms of the appearance of openings, and it also exposes the latchbolt and keeper mechanism to unintentional users.
Recently, several electric strike makers have come up with an innovative type of electric strike, dubbed the "No Cut" strike that doesn't require a cutout in the doorjamb to operate. The strikes have a unique design that allows the latchbolt and keeper to slide into the pocket without damaging the faceplate of the doorjamb.
The strike has 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 pushes them up higher on the ramp, locking the door. When the door is shut the deadbolt remains at a lower position and the latchbolt retracts into the keeper.
Installing an electric strike is a simple process, especially when you are replacing an existing strike door. However, if you are upgrading to an electric strike in an access control system, you'll need to make sure your new system is compatible with the model of lock you've chosen to install. Also, you must make sure that the strike is properly wired to your access control system and that it is configured for fail-safe operation.
One way to safeguard against access by unauthorized persons is to upgrade the strike on your doors to a heavy-duty strike plate. The plates are made of up to six screws of three inches instead of two screws of three-fourths of an inch. These screws are longer, making it more difficult for people to break the frame and reach inside to turn the thumb turn part of a single deadbolt cylinder.
