20 Reasons Why Replace Door Lock Cannot Be Forgotten

How to Replace Door Locks

The first security measure is your door lock. It can stop unauthorised entry to your home. Locks may require replacement due to signs of wear and tear or other events such as moving into a new home 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 appropriate lock.

Deadbolt

If you want to ensure your door is safe from intruders, it's a good idea to install deadbolts. 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 can be activated with a key on the exterior, and the thumb-turn mechanism situated inside. Deadbolts are only effective if it's installed correctly, though.

The first step is to determine if the door has a hole to install a deadbolt 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 kit. Use your tape measure to determine the height of the deadbolt. Then, mark this height on the side of the door and use the speed square to draw straight lines across the mark you made for the bolt hole.

Next, use a power drill to drill this hole until it extends to the opposite side of the door. This may take a while. Then, sand the hole and the edges of the door so that it's smooth. It's also recommended to stain or paint the door at this point.

Once the door is ready take off any screws that are visible on the existing deadbolt. This will reveal the back and front assemblies of the deadbolt, and also the bolt that is inside. Then, unscrew  replacement upvc door lock  and replace it with a new one that matches the door hardware. It is necessary to remove the bolt from a setplate. Then, you'll need to chisel the surface of the door frame for the strike plate.

If your strike plate is not in alignment, it could be because the previous installer did not mortise it properly, or a weatherstripping has changed the strike's location. You will need to re-mortise your strike plate and perhaps even the deadbolt to correct this problem. Close and lock the deadbolt once you've completed this step. Make sure the bolt extends into the strike plate, and then test the key to make sure it closes and opens smoothly.

Knob

If the knob on your door is damaged it could make your business or home less secure. It may make it more difficult to open or close the door, so it's recommended to replace the knob. It shouldn't take more than 30 minutes. You can use a screwdriver or pliers to take off the old knob or handle, but be careful not to harm any of the other components on the door.

Before you begin you'll need to spray WD-40 or a different dry lubricant onto the mechanism of the knob for your door. This will help the lock to move smoothly when you turn it. It's essential to select a quality knob and handle that match the doors you currently have to ensure that the lock is operating properly. If you don't have a matching doorknob and handle, you'll need to purchase a new one.

To begin the replacement process, look at the knob or handle to determine what screws hold 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 that was previously used, look it over for signs of rust or damage. If the knob has any dents or marks then you'll need clean it. Otherwise it shouldn't require any major work.

Install the new knob. You must first study the two knobs in order to make sure that you are choosing the right one for the door. You'll want to pick one with an extended rod that is designed to lock with the second knob's rod mechanism. After you've placed the new knob into the hole, slide it into the latch.

Test the spring by pressing it repeatedly. The latch should spring back up every time. Install the second knob and secure it to the rod mechanism of the first knob. Thread the long screws from the interior doorknob through the holes for the cylinder on the outside knob and fix it in its place.

Latch

A latch is a steel piece that extends into the doorjamb to secure it shut. The latch is operated via a knob or handle on the inside of the door, or by a thumb-turn on the exterior. A latch can be secured by deadbolts to stop intrusions from piercing the glass of the door. It can also protect against the accidental or deliberate closing by pets or children. The latch can be fitted with single cylinder deadbolts or double cylinder deadbolts depending on the security level you prefer.

Installing a latch requires the same steps similar to installing a deadbolt however there are some distinctions. First, you must measure the setback of the doorjamb using a tape measure to be sure 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. Setbacks for standard latches are 2 3/8 to 2. 3/4 inches. If you have a higher setback, you might need to purchase a more substantial latch from a hardware shop or locksmith.

The next step is to drill an edge bore hole into the doorjamb to accommodate the latch plate. Use a chisel and cut the mortise of the latch. Make sure the depth is enough for the faceplate to be in line with the doorjamb. Tape the strikeplate in place to ensure it's placed correctly.

If the strike is too high, you could push the door back or apply pressure using the tire iron or crowbar. This can also crack the doorjamb. This can be repaired by drilling a new hole in the doorjamb, and chiseling the core out of the previous one.

The last step is to mount the new strike plate, which can be done by screwing it in place over the screw holes that are already in place. Use wood putty then to fill in any old screw holes or bolt holes that aren't being used. Once the putty has dried you can sand it until it has a smooth finish.

Strike

The metal piece that engages the deadbolt and latch when the door is shut is an electric strike. It is an important part of the security of a lock, because it helps keep 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 can be opened only by an entry key and a control unit that controls its electrical impulses.

Traditionally, installing an electric strike required cutting out a portion of the doorjamb in order to release 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 strike manufacturers have created a new type of electric strike called the "No Cut" strike that doesn't require an opening in the doorjamb to function. They use a specific design that allows the latchbolt and keeper to slide into the pocket without causing damage to the doorjamb's faceplate.

The strike has an internal ramp that raises the keeper and latchbolt when it receives an electrical signal from a reader or controller. The retracting of the keeper and latchbolt causes them to rise on the ramp, locking the door. When the door is closed the deadbolt remains at a lower position and the latchbolt retracts into the keeper.

Installing an electronic strike is a simple process, particularly in the case of replacing an existing strike. If you are upgrading an access control system to an electric strike, you need to ensure that the new system is compatible. It is also necessary to ensure that the strike is connected to your access control system and that it is set up for fail-safe operation.

One method to guard against access by unauthorized persons is to upgrade the strike on your doors to a heavy-duty strike plate. The plates utilize four to six screws of three inches instead of the two three-fourth inch screws that are typically employed in regular strikes. The longer screws make it difficult for anyone to break the frame and reach inside to turn the thumb turn part of a single cylinder deadbolt.
