How to Replace Door Locks
Your first line of defense is your door lock. It will stop unauthorized entry to your home. The locks may require replacement due to signs of wear and tear, or other situations such as moving into a new home or a break-in.
To begin, determine the size of your cylinder by measuring the distance between the adjustment screw and the middle of the knob lock cylinder. This measurement will enable you to purchase the correct-sized lock.
Deadbolt
Installing a deadbolt is excellent way to protect your door from intruders. When the bolt is extended into the strike plate of the doorframe it makes it harder for an intruder through the door. A single-cylinder deadbolt is activated with a key on the exterior and the thumb-turn mechanism located on the interior. Deadbolts can only function if it is installed correctly.
First, you must determine whether the door already has an existing hole for a deadbolt, or if you’ll need to drill it. Mark the location of the hole to install the deadbolt on the exterior of the door by using the template supplied with the lock installation set. Then, use the tape measure to determine the height the deadbolt needs to be. Mark this measurement on the door’s edge. Use the speedsquare to draw a straightline across the mark that you made to mark the bolt hole.
Then by using the power drill, drill out the hole until it is on the opposite side of the door. This may take some time. 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.
Remove any visible screws from the deadbolt. This will reveal the front and rear assemblies of the deadbolt, as well as its internal bolt. Then, remove the bolt and replace it with a brand new one that is compatible with your door hardware. You’ll need to remove the bolt from a setplate. After that, you’ll have to chisel the area on the door frame for the strike plate.
If your strike plate is out of alignment it could be because the previous installer failed to mortise it properly, or a weatherstripping has changed the strike’s location. You’ll need to re-mortise the strikeplate and possibly even the deadbolt itself to fix this issue. Close and lock the deadbolt when you’ve completed this process. Make sure that the bolt is extending into the strike plate and then test the key to ensure it opens and closes easily.
Knob
It could make your business and home less secure when the door knob is damaged. It may make it difficult to open or close the door, making it recommended to replace it. Replacing a knob is a relatively easy DIY task that should not take less than 30 minutes to complete. You can use a screwdriver and pliers to remove the old knob or handle However, be careful not to damage any of the other components on the door.

It’s essential to select a quality knob and handle that match the doors you currently have to ensure proper operation. If you don’t have a matching knob then you’ll have to purchase a new doorknob and latch plate.
Before you begin the replacement, look over the knob you replaced to determine which screws are holding 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.
Once you’ve removed the old knob, examine it for any signs of rust or damage. If the knob shows any marks or scratches it’s time clean it. Otherwise, it shouldn’t require any major work.
Install the new knob. You should first examine the two knobs in order to make sure that you are choosing the right one for the door. You’ll need to pick one with an extending rod that will interlock with the rod mechanism of the other knob. After you’ve placed the new knob in the door’s hole carefully insert it into the latch.
Thread the latch plate screws downwards and test the spring by pushing down several times. The latch should spring back up every time. Then, you can install the new knob and connect it to the rod mechanism on the first knob. Thread in the other long screws from the interior knob through the hole in the cylinder of the doorknob outside and secure it.
Latch
A latch is a piece metal that extends through the doorjamb to hold it closed. It is operated by a knob or handle on the inside of the door or by a thumb turn on the exterior side of the door. A latch can be secured using deadbolts to stop thieves from breaking through the glass of the door. It also protects against the accidental or deliberate closing of the door by pets or children. You can choose to install a latch with either a single-cylinder deadbolt or double-cylinder deadbolt, depending on the level of security.
Installing a deadbolt is the same as installing a latch, however, there are some distinctions. First, determine the setback of the doorjamb with a tape measure to make sure that the new lock will fit. The setback is measured from the edge of the 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 you have a greater setback, you might need to purchase a more substantial latch from a hardware store or locksmith.
Next, drill a hole for the latch plate into the doorjamb’s edge. Utilize a chisel to smooth out the mortise of the latch and ensure it’s deep enough for the faceplate of the new latch to be flush with the doorjamb. Put the strike plate into 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 also cause cracks in the doorjamb. To fix this, the strike could be reduced by drilling a second hole in the doorjamb and cutting out the core of the hole that was previously drilled.
The final step is to put in the new strike plate, which can be accomplished by screwing it in place over the existing screw holes. Utilize wood putty to fill in any existing screw holes or bolt holes that won’t be used. After the putty is dry then sand it to a smooth finish.
Strike
An electric strike is a metal part where the latch and deadbolt engage when the door is shut. It is a vital part of the lock’s overall safety, as it prevents the door from opening and gives an additional barrier to force or kicking. If a door has been equipped with an electric strike, it can only be opened by keys or the control unit that controls the electrical impulses.
Traditionally the installation of an electric strike involved cutting a section of the doorjamb to remotely remove a cylindrical lock’s latchbolt from the pocket of the strike. This modification can be a drawback when it comes to the appearance of an opening, and it also exposes the keeper mechanism and latchbolt to unintentional users.
Recently, several electric strike makers have come up with a brand new electric strike called the “No Cut” strike that doesn’t require an opening in the doorjamb to function. These strikes have a unique design that allows the keeper and latchbolt to slide into the strike pocket without marring the doorjamb faceplate.
The strike has an internal ramp which lifts the latchbolt as well as the keeper when it receives an indication from a reader. The keeper and latchbolt are pushed higher up the ramp by the retract. When the door is shut, the deadbolt remains in place and the latchbolt retracts in the keeper.
Installing an electronic strike is a straightforward procedure, particularly in the case of replacing an existing strike. 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. Also, you must make sure 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 high duty strike plates to block unauthorised entry. These plates use up to six screws of three inches instead of the standard two screws of three-fourths inches. These longer screws make it more difficult for anyone to break the frame and then reach inside to turn the thumb turn part of a single cylinder deadbolt.
