How to Replace Door Locks
The first protection is your door lock. It will stop unauthorized entry into your home. The locks may need to be replaced due to signs of wear and tear or other events like moving into a new home or a burglary.
To begin, determine the size of your cylinder using the distance between the adjustment screw and the middle of the cylinder knob. This measurement will enable you to buy the right lock.
Deadbolt
Installing a deadbolt is a great way to secure 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 to break through the door. A single-cylinder deadbolt is activated by a key located on the outside and the thumb-turn mechanism located on the interior. Deadbolts are only effective if it's installed correctly however.
The first step is to find out if the door has a hole to install a deadbolt or if it requires drilling. Mark the location of the hole to install the deadbolt on the surface of the door using the template that came with your lock installation kit. Use a tape measure to determine the height of the deadbolt. Then, mark this height on the edge of the door. Use the speed square to draw a straight line across the mark you made for the bolt hole.
Then, use a drill to bore out this area until the hole is on the other side of the door. This may take a while. Sand the hole and the door edge to smooth it. It's also an excellent idea to stain or paint the door at this point.
When the door is in place remove any screws visible on the existing deadbolt. This will reveal the back and front assemblies of the deadbolt and also the bolt inside. Remove the bolt and replace it by the new bolt to match your door hardware. You will need to unscrew the bolt from a setplate. Then, you'll need to chisel the door frame to accommodate the strike plate.
If your strike plate isn't aligned properly, it's likely because the previous installer didn't properly mortise it or a weatherstripping came along and changed the strike's position. You will need to re-mortise the strikeplate and possibly even the deadbolt to correct this problem. After this is done check the deadbolt by closing and locking it. Test the deadbolt by closing and locking it after the bolt has been extended into the strike plate.
Knob
It could make your home or business less secure if the door knob is worn. It could also make opening and closing the door more difficult, so it's an ideal idea to replace the knob. It shouldn't take longer than 30 minutes. You can use a screwdriver or pliers to take off the old knob or handle Be careful not to harm any other parts on the door.
Before you start, you'll want to spray WD-40 or some other dry lubricant onto the mechanism of the knob for your door. This will let the new lock to slide effortlessly as you turn it. It's essential to select the best knob and handle that match your doors currently in order to ensure that the lock is operating properly. If there's no match, you'll need to buy a replacement doorknob and latch plate.
To begin the replacement process, examine the old knob or handle to find what screws hold it in place. If there aren't replacement lock for upvc door can use a screwdriver to insert between the cover plate and the screws plate hidden and remove it.
After taking the knob off take it apart and look for signs of rust and damage. It's important to clean it off if there are any scratches or marks, but you shouldn't have to do anything major If the knob is in good working order.
It's time to install the new one. You must first study the two knobs in order to make sure that you are choosing the correct one for your door. You should select one with an extended rod designed to interlock with the rod mechanism of the second knob. After you've placed the new knob in the hole then slide it into the latch.
Test the spring by pressing down on it repeatedly. The latch should rise each time. Next, install the other new knob and connect it to the rod mechanism on the first knob. Thread the long screws of the doorknob's interior through the cylinder holes on the exterior knob, and fix it in place.
Latch
A latch is a steel piece that extends out into the doorjamb to secure 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 a deadbolt to keep intrusions from piercing the glass. It also provides protection from accidental or intentional closing of the door by pets or children. It is possible to install an entry point with either a single-cylinder or double-cylinder deadbolt based on your preferred level of security.
Installing a latch requires the same steps like installing a deadbolt however, there are a few differences. First, measure the setback of the doorjamb using an instrument to make sure that the new lock will fit. The setback is measured from the edge of the doorjamb up to the center of hole for the latch plate. A 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 larger from a hardware or locksmith store.
The next step is to drill an edge bore hole through the doorjamb for the latch plate. Utilize a chisel to smooth out the latch mortise and ensure it's deep enough to allow the faceplate of the new latch to be close to the doorjamb. Put the strike plate into the correct position to ensure it is positioned correctly.
If the strike is too high, you could knock the door down or apply pressure using the tire iron or crowbar. This can also crack the doorjamb. To fix this, the strike can be reduced by drilling a second hole into the doorjamb and chiseling out the center of the previous hole.
The final step is to mount the new strike plate, which can be accomplished by screwing it in place over the existing screw holes. Then you can use wood putty to fill in the old screw holes and the bolt hole that will not be used. Once the putty is dry you can sand it down to give it a professional results.
Strike
An electric strike is a metal piece where the latch and deadbolt engage when the door is closed. It is a vital component of the overall security of a lock as it seals the door and offers additional resistance to force or kicks applied to the door. If a door comes with an electronic strike, it will be opened only with keys and the control unit that regulates the electrical impulses.
Traditionally the installation of an electric strike required cutting out a portion of the doorjamb to remotely remove the latchbolt of a cylindrical lock from the pocket of the strike. This is not only ugly and unattractive, but also exposes the mechanism for the latchbolt and keeper to uninitiated users.
Recently, a variety of electric strike manufacturers have developed a "No Cut" type of strike that doesn't require a cutout in order to operate. These strikes have a unique design to allow the latchbolt and keeper to slide into the strike pocket without marring the faceplate of the doorjamb.
The strike is equipped with an internal ramp that raises the latchbolt and keeper whenever it receives an electrical signal from a reader or controller. The keeper and latchbolt are pushed higher up the ramp by the retraction. When the door is shut, the deadbolt stays extended and the latchbolt is retracted into the keeper.
Installing an electric strike can be a simple process, especially in the case of replacing the strike on a previous door. However, if you are 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 chosen to install. You will also need to ensure that the strike is properly connected to your access control system and that it is configured for fail-safe operation.
Upgrade your strike plates to heavy duty strike plates to prevent the entry of unauthorized persons. The plates utilize four to six three-inch screws instead of the two, three-fourth inch screws commonly used in standard strikes. These screws are longer, making it more difficult for anyone to break the frame and then reach inside to turn the thumb turn part of a single cylinder deadbolt.
