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 to break through the door. A single cylinder deadbolt can be activated using keys on the exterior side and a thumb turn piece on the inside. A deadbolt will only work if it is installed correctly.

The first step is to determine if the door already has a hole to install a deadbolt or if it has to be bored. Mark the location of the hole for the deadbolt on the surface of the door using the template that came with your lock installation set. Utilize your tape measure to determine the height of the deadbolt. Then, mark the high point on the outside of the door. Use the speed square to draw a straight line across the mark you made for the bolt hole.

Then by using the power drill, drill through the hole until it reaches the opposite side of the door. This could take a bit of time. Then, sand the hole and along the edge of the door until it's smooth. It's also an excellent idea to paint or stain the door at this point.

Remove any visible screws from the deadbolt. This will reveal the front and rear assemblies of the deadbolt and its bolt inside. Then, loosen the bolt and replace it with a new one that matches your door hardware. You'll need to remove the bolt from a setplate. Once this is done then you need to chisel the area for the strike plate on the door frame.

If your strike plate isn't aligned properly it's likely that the previous installer didn't mortise it correctly or a weatherstripping came along and changed the strike's position. To fix this problem you'll need to remortise both the strike plate and the deadbolt. Close and lock the deadbolt once you've completed this process. Test the deadbolt by closing and locking it after the bolt has been extended into the strike plate.

To begin the replacement process, first look over the knob or handle to determine what 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 plate with hidden screws and pop it off.

Once you've removed the old knob, examine it for any indications of damage or rust. If the knob shows any scratches or marks then you'll need to clean it. Otherwise, it shouldn't require any major work.

Install the new knob. You should first examine the two knobs to ensure that you are choosing the right one for the door. You'll need to choose one with an extending rod that will interlock with the rod mechanism of the second knob. After you've placed the new knob into the hole and then put it in the latch.

Thread the latch plate screws down and test the spring by pressing down on it several times. The latch should spring up each time. Next, install the other new knob and lock it with the rod mechanism on the previous knob. Thread in the other long screws from the knob's interior through the hole in the cylinder of the doorknob on the outside and secure it.

Latch

A latch is a steel piece that extends into the doorjamb to keep it shut. The latch is operated either via a knob or handle on the inside of the door, or by a thumb-turn on the outside. Deadbolts can be used to secure a latch and stop intrusions from breaking through the glass of the door. It also offers protection from accidental or intentional closing of the door by children or pets. A latch can be set with a single cylinder deadbolt or a double cylinder deadbolt, based on the level of security you prefer.

Installing a latch follows the same steps like installing a deadbolt however there are some distinctions. To ensure that the new lock will fit first, determine the setback of the doorjamb with a tape measure. The setback is the distance between the edge of the doorjamb to the middle of the hole that will be used for the faceplate of the latch. Standard setbacks are 2 3/8 to 2. 3/4 inches. If you have a higher setback, you might need to purchase a longer latch from a hardware store or locksmith.

The next step is to drill an edge bore hole through the doorjamb to accommodate the latch plate. Use a chisel for chiseling out the latch mortise, making sure it's deep enough for the faceplate of the new latch to be in a flush position with the doorjamb. Tape the strike plate in place to ensure that it is positioned correctly.

If the strike is too high, you can kick the door in or apply pressure with replacing a patio door lock tire iron or crowbar. This could cause the doorjamb to crack. This can be repaired by drilling a new hole in the doorjamb, then chiseling the core out of the previous one.

Strike

The piece of metal that connects the latch and deadbolt when the door is shut is an electric strike. It is an essential component of the lock's security, as it prevents the replacing upvc door lock mechanism from opening, and also provides an additional level of resistance to force or kicking. If a door is equipped with an electronic strike, it will be opened only by a key and the control unit that controls its electrical impulses.

Traditionally, installing an electric strike meant cutting out a portion of the doorjamb in order to remotely release a cylindrical lock's latchbolt from the pocket within the strike. This is not only ugly and unattractive, but also exposes the mechanism for the latchbolt and keeper to uninitiated users.

Recently, several electric strike manufacturers have created a brand new electric strike called the "No Cut" strike that doesn't require cutouts in the doorjamb to function. These strikes utilize a special design that allows the latchbolt and keeper to slide into the strike pocket without damaging the doorjamb faceplate.

The strike is equipped with an internal ramp that raises the latchbolt and keeper when it receives an electrical impulse from a reader or controller. The retracting of the keeper as well as latchbolt pushes them up higher on the ramp, which locks the door. When the door is closed the deadbolt is retracted and the latchbolt is retracted into the keeper.

Installing an electric strike is an easy process, particularly if you are replacing upvc door locks the strike on a previous door. However, if you are upgrading to an electric strike to use with an access control system, you'll be required to ensure that the new system is compatible with the kind of lock you've chosen to install. Also, you must make sure that the strike is properly connected to your access-control system and is configured to operate in a fail-safe manner.

Upgrade your strike plates to heavy duty strike plates to prevent unauthorized entry. These plates use four to six three-inch screws instead of the two, three-fourth inch screws commonly employed in regular strikes. The longer screws make breaking the frame to reach the piece that turns the thumb on a single cylinder deadbolt more difficult.
