How to Replace Door Locks
Door locks are your primary protection against unauthorised access to your home. The signs of wear and tear, as well as instances like moving into a new residence or burglaries, could trigger the necessity of replacing your lock.
To begin, determine your cylinder size by measuring the distance between the adjustment screw and the middle of the knob lock cylinder. This measurement will help you purchase the right-sized lock.
Deadbolt
Installing a deadbolt is excellent way to protect your door from burglars. When the bolt is extended into the strike plate of the doorframe, it makes it much more difficult for an intruder to get through the door. A single cylinder deadbolt is activated using a key on the exterior side and a thumb turn device on the interior. A deadbolt will only work when it's properly installed however.
First, you must determine whether the door already has an existing hole for a deadbolt or if you have to drill it. Using the template that comes with your lock installation kit, mark the spot of the deadbolt's hole on the door's surface. Then, you can use your tape measure to determine how high the deadbolt needs to be. Mark this measurement on the door's edge. Use a speedsquare to draw a straight line across the mark you made for the bolt hole.
Next, use a power drill to bore out this hole until it extends to the opposite side of the door. This could take a bit of time. Then, sand down the hole and along the edge of the door until it's smooth. At front door locks replacement barnet Repair My Windows And Doors , it's a good idea also to paint or stain your door.
When the door is open remove any screws that are visible on the deadbolt. This will reveal the front and back assembly of the deadbolt as well as the internal bolt. Then, unscrew the bolt and replace it with a new bolt that matches the door hardware. The bolt is typically attached to a set plate, which you will need to unscrew. After this, you'll need to chisel the surface of the door frame for the strike plate.
If your strike plate is misaligned it's likely that the previous installer didn't mortise it correctly or a weatherstripping came along and altered the strike position. To correct this issue it is necessary to remortise both the strike plate as well as the deadbolt. Once this is completed, test the deadbolt by closing it and locking it. Test the deadbolt by closing it and locking it after the bolt has been extended into the strike plate.
Knob
If a door knob wears out it could make your business or home less secure. It may also make it harder to open or close the door, which is why it's an ideal idea to replace it. Replacing knobs is an easy DIY project and shouldn't take less than 30 minutes to complete. You can use a screwdriver as well as pliers to remove the knob or handle However, be careful not to damage any other parts on the door.
Before you begin, you'll want to spray WD-40 or another dry lubricant onto the mechanism of the knob on your door. This will help the new lock move smoothly when 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 there's no match then you'll have to purchase a replacement doorknob and latch plate.
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, you can use a screwdriver to wedge between the cover plate and the hidden screws plate and remove it.
After you've removed your knob, check it for any indications of damage or rust. If the knob shows any scratches or marks, you'll have to clean it. Otherwise, it shouldn't require any major work.
Install the new knob. First, examine the two new knobs to ensure that you're picking out the right one for your door. You'll need to select one with an extending rod that will interlock with the rod mechanism of the second knob. Once you've positioned the new knob in the hole in the door and then carefully insert it into the latch.
Thread the latch plate screws downwards and then test the spring by pressing 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 in the other long screws from the interior knob through the hole for the cylinder on the doorknob outside and lock it in place.
Latch
A latch is a piece of metal that extends through the doorjamb to hold it shut. The latch can be operated via a knob or handle on the inside of the door, or by a thumb-turn on the exterior. The latch can be secured using a deadbolt to keep intrusions from piercing the glass. It also helps protect against the accidental or deliberate closing by animals or children. You can install an entry point with either a single-cylinder deadbolt, or a double-cylinder deadbolt, depending on the level you prefer for security.
Installing a deadbolt is exactly the same as installing a latch, however there are some differences. To make sure that the new lock is compatible, first measure the setback on the doorjamb using an instrument such as a tape measure. The setback is measured from the edge of doorjamb all the way to the center of hole for the latch plate. Setbacks for standard latches are 2 3/8 to 2. 3/4 inches. If your setback is larger than that, you might need to purchase a latch that is longer from a hardware or locksmith store.
The next step is to drill an edge bore hole through the doorjamb for the latch plate. Use a chisel and chisel the latch mortise. Make sure the hole's depth is sufficient for the faceplate to be in line with the doorjamb. Tape the strikeplate in place to ensure it is positioned correctly.
If the strike is positioned too high, the door could be pushed in or pressure put on it with a crowbar or tire iron. This could cause the doorjamb to break. This can be repaired by drilling a new hole through the doorjamb and then cutting the core from the hole that was previously made.
Installing the new strike plate is the last step. This can be done by screwing the new plate into the existing screw holes. Then, use wood putty to fill in the holes from the previous screws and the bolt hole that won't be used. After the putty has dried then sand it to a smooth finish for an elegant finish.
Strike
An electric strike is a metal piece where the deadbolt and latch are engaged when the door is shut. It is a vital component of a lock's overall security, because it keeps the door shut and provides extra resistance to force or kicks applied to the door. If a door is equipped with an electronic strike, it can be opened only with a key 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 in the strike. This modification is not just unattractive however, it also exposes the latchbolt mechanism and keeper to unauthorized users.
Recently, several electric strikes manufacturers have come up with a "No Cut" type of strike that does not require a cutout for operation. 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 whenever it receives an electrical signal from a controller or reader. The keeper and latchbolt are pushed higher on the ramp thanks to the retraction. When the door is shut, the deadbolt remains in place and the latchbolt is retracted into the keeper.
Installing an electric strike is an easy process, particularly in the case of replacing the strike on a previous door. If you're planning to upgrade an existing access control system to an electric strike, you must make sure that the new system is compatible. You will also need to make sure that the strike is wired to your access control system and that it is designed 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 robust strike plate. These plates use up to six screws of three inches instead of the standard two screws of three-fourths of an inch. These screws are longer, making it more difficult for anyone to break the frame and reach inside to turn the piece that turns the thumb of a single deadbolt cylinder.
