How to Replace Door Locks

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 can be a great way to secure your door from burglars. When the bolt is extended into the strike plate of the doorframe it makes it harder for an intruder to get through the door. A single-cylinder deadbolt is activated by a key located on the exterior and the thumb-turn mechanism situated inside. Deadbolts can only function if it is installed correctly.
First, you will need to determine if the door has a hole for deadbolts or has to be bored. Mark the location of the hole for the deadbolt on top of the door using the template that came with your lock installation kit. Then, use your tape measure to determine how high the deadbolt should be. Mark this high point on the door's edge, and then use a speedsquare to draw a straight line across the mark you made for the bolt hole.
Then by using a power drill, bore through the hole until it is on the opposite side of the door. This may take a while. Sand the hole and the door edge to make it smooth. It's also recommended to stain or paint the door at this point.
Remove any screws that are visible from the deadbolt. This will reveal both the rear and front assembly of the deadbolt and its internal bolt. Then unscrew the old bolt and replace it by the new bolt to match the door hardware. The bolt is usually connected to a setplate, which you will need to unscrew. After that, you'll have to chisel the area on the door frame for the strike plate.
If your strike plate is not in alignment It could be due to the previous installer failed to mortise it properly or that a weatherstripping changed the strike position. To correct this issue, you will need to remortise both the strike plate as well as the deadbolt. Close and lock the deadbolt when you've completed this process. Be sure the bolt is extending into the strike plate then test the key to ensure it opens and closes effortlessly.

Replacing the knob is an simple DIY project that shouldn't take less than 30 minutes to complete. Make use of pliers or a screwdriver to remove any knobs or handles. Be cautious not to harm the other components of the door.
Before starting, you'll want to spray WD-40 or a different dry lubricant on the mechanism of the knob for your door. This will allow the new lock to slide effortlessly when you turn it. To ensure proper operation it is essential to select a knob and handle that match the doors you already have. If you don't already have a doorknob that is compatible then you'll have to buy a replacement.
To begin the replacement process, examine the old knob or handle to see what screws hold it in place. If there aren't screws then you can use the screwdriver to wedge the cover plate in between the screws plate that is hidden.
Once you've removed the knob, check it for any signs of damage or rust. You'll have to scrub it up if there are any scratches or marks however you don't need to do anything If the knob is in good condition.

You'll need to choose one with an extended rod that is interlocked with the rod mechanism of the other knob. Once you've put the new knob in the hole and then put it in the latch.
Thread the latch plate screws downwards and then test the spring by pushing down repeatedly. The latch should spring back up each time. Install the second knob and lock it to the rod mechanism of the first knob. Attach the other long screws from the knob's interior through the cylinder hole on the doorknob on the outside and lock it in place.
Latch
A latch is a piece metal that extends through the doorjamb to hold it shut. It is operated with a knob or handle on the inside of the door or by a thumb turn on the outside side of the door. Deadbolts can be used to secure a latch and stop intruders from breaking through the glass of the door. It can also protect against the accidental or deliberate closing by pets or children. You can install a latch with either a single-cylinder deadbolt or double-cylinder deadbolt, depending on the level of security.
Installing a latch involves the same steps like installing a deadbolt however, there are a few differences. To ensure that the new lock is compatible, first measure the setback on the doorjamb with an instrument such as a tape measure. The setback is the distance from the edge of the doorjamb to the middle of the hole that will be used for the latch faceplate. A typical setback is 2 3/8 to 2 3/4 inches. If you have a greater setback, you may need to purchase a larger latch at a hardware store or locksmith.
Next, make a hole for a latch plate into the edge of the doorjamb. Utilize a chisel to cut the mortise of the latch. Make sure the hole's depth is enough to allow the faceplate to be in line with the doorjamb. Place the strikeplate on the floor to ensure that it's positioned properly.
If the strike is too high, you can push the door back or apply pressure with a tire iron or crowbar. This can also crack the doorjamb. To remedy this, the strike could be reduced by drilling a second hole through the doorjamb, and then chiseling out the core of the previous hole.
The last step is to install the new strike plate which is done by screwing it over the existing screw holes. Use wood putty then to fill in any existing bolt holes or screw holes which aren't going to be used. Once the putty is dry you can sand it down to give it a professional results.
Strike
The metal piece that engages the latch and deadbolt when the door is closed is an electric strike. It is an important part of a lock's overall security, since it keeps the door shut and provides extra resistance to force or kicking applied to the door. If a door is equipped with an electronic strike, it can be opened by using keys and the control unit that controls its electrical impulses.
In the past, putting in an electronic strike was as simple as cutting a piece of a doorjamb, which would let the latchbolt of a cylindrical lock from the pocket that is inside the strike. This modification can be an issue when it comes to the appearance of openings and also exposes the keeper mechanism and latchbolt to unintentional users.
Recently, several electric strikes manufacturers have developed a "No Cut" type of strike that doesn't require a cutout to operate. These strikes utilize a special design to allow the latchbolt and keeper to slide into the strike pocket without damaging the faceplate of the doorjamb.
The strike is equipped with an internal ramp that lifts the latchbolt and keeper whenever it receives an electrical signal from a controller or reader. The retraction of the keeper and latchbolt raises them on the ramp, thereby locking the door. When the door is shut the deadbolt remains in at a lower position and the latchbolt retracts into the keeper.
Installing an electric strike is an easy process, particularly if you are replacing the strike on a previous door. If you're planning to upgrade an access control system to an electric strike, it is important to ensure that your new system is compatible. Also, you must make sure that the strike is properly connected to your access control system and is set up to function in a fail-safe manner.
Upgrade your strike plates to high duty strike plates to prevent the entry of unauthorized persons. These plates use four to six screws of three inches instead of the two three-fourth inch screws typically used in standard strikes. The longer screws make breaking the frame to reach the piece that turns the thumb on a single cylinder deadbolt more difficult.
