Deadbolt

Installing a deadbolt is a excellent way to protect your door from intruders. 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 with an exterior key on the side and a thumb turn part on the inside. A deadbolt is only effective only if it's correctly installed however.

First, you will need to determine if the door has a hole to install a deadbolt or if it requires drilling. With the template included with your lock installation kit, mark the location of the hole for the deadbolt on the door's surface. Then, use your tape measure to determine how high the deadbolt should be. Mark this height on the door edge, and then use a speedsquare to draw a straight line across the mark that you made to mark the bolt hole.

Then, using a power drill, bore out the hole until it reaches the opposite side of the door. This may take some time. Then, sand down the hole and the edge of the door until it is smooth. It's also an excellent idea to stain or paint the door at this point.

Remove any screws that are visible from the deadbolt. This will reveal both the front and rear assemblies of the deadbolt and its internal bolt. Then unscrew the old bolt and replace it with a new one to match your door hardware. The bolt is typically attached to a set plate, which you will have to remove. Once this is done then you need to chisel out the area for the strike plate on the door frame.

If you don't already have a matching doorknob, you will need to purchase a replacement.

To begin the replacement process, first look at the knob or handle to determine what screws are holding it in place. If there are no screws, you can use the screwdriver to wedge the cover plate between the hidden screws plate.

After you've removed your knob that was previously used, look it over for signs of damage or rust. If the knob shows any dents or marks, you'll have to clean it. Otherwise it shouldn't require any major work.

Install the new knob. You must first study the two knobs to ensure that you've chosen the correct one for your door. You'll need to choose one with an extended rod that is designed to lock with the rod mechanism of the second knob. After you've placed the new knob in the hole, slide it into the latch.

Thread the latch plate screws down and then test the spring by pushing down repeatedly. The latch should spring up each time. Install the second knob, and lock it to the rod mechanism of the first knob. Thread in the other long screws from the knob's interior through the hole in the cylinder of the doorknob outside and lock it in place.

Latch

A latch is a piece of metal that extends into the doorjamb to hold it closed. The latch is operated via a knob or handle on the interior of the door, or by a thumb-turn on the outside. A deadbolt is a device used to secure a latch and keep intruders from breaking through the glass of the door. It also provides protection from the accidental or deliberate closing of the door by pets or children. The latch can be fitted using a single cylinder deadbolt or a double cylinder deadbolt, based on the level of security you prefer.

Installing a latch involves the same steps like installing a deadbolt however there are some differences. To ensure that the new lock is compatible first, determine the setback of the doorjamb using the tape measure. The setback is the distance from the edge of the doorjamb to the center of the hole that will be used for the latch faceplate. A typical setback is 2 3/8 to 2 3/4 inches. If your setback is higher, you may need to purchase a latch that is longer from a locksmith or hardware store.

Then, make a hole for the latch plate at the doorjamb's edge. Utilize a chisel to smooth out the latch mortise, making sure it's deep enough for the faceplate of the new latch to sit flush with the doorjamb. Place the strike plate in the correct position to ensure it's placed correctly.

Installing the new strike plate is the final step. This can be done by screwing the new plate into the screw holes that are already in place. Then you can use wood putty to cover the old screw holes and the bolt hole that will not be used. When the putty is dry then sand it to a smooth finish for professional results.

Strike

The piece of metal that connects the deadbolt and latch when the door is shut is an electric strike. It is a vital part of the lock's overall security because it prevents the door from opening, and also provides an additional level of resistance to force or kick. If a door is equipped with an electronic strike, it can be opened only with keys and the control unit that regulates its electrical impulses.

Traditionally, installing an electric strike required cutting a section of the doorjamb in order to release the latchbolt of a circular lock from the pocket of the strike. This modification can be a drawback in terms of the appearance of an opening, and it also exposes the keeper mechanism and latchbolt to any unauthorised users.

Recently, a number of electric strike makers have come up with a brand new electric strike dubbed the "No Cut" strike that doesn't require cutouts in the doorjamb to function. These strikes utilize a special design to allow the keeper and latchbolt to slide into the strike pocket without marring the doorjamb faceplate.

The strike is equipped with an internal ramp which lifts the latchbolt and keeper when it receives an indication from an individual reader. The keeper and latchbolt are pushed up the ramp due to retract. When the door is closed the deadbolt remains in extended and the latchbolt is retracted into the keeper.


Installing an electric strike can be an easy task, especially in the case of replacing an existing strike door.

These plates are fitted with four to six screws of three inches instead of the two three-fourth inch screws commonly used in standard strikes. These screws are longer, making it difficult for anyone to break the frame and reach inside to turn the piece that turns the thumb of a single cylinder deadbolt.
