Deadbolt

Installing a deadbolt is excellent way to protect your door from burglars. 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 a thumb-turn piece located on the interior. A deadbolt is only effective when it's properly installed however.

It is first necessary to determine whether the door already has a hole that is suitable for a deadbolt, or if you need to drill it out. With the template included with your lock installation kit, mark the location of the hole for the deadbolt on the door's surface. Use a tape measure to determine the height of the deadbolt. Then, mark this high point on the outside of the door. You can then use the speed square to draw straight lines across the mark you made for the bolt hole.

Then, use a power drill to drill this spot until the hole reaches the opposite side of the replacing upvc door lock and handle. It may take a while. Then, sand down the hole and the edge of the door until it is smooth. At this point, it's a good idea to stain or paint your door.

Once the door is ready take off any screws that are visible on the deadbolt. This will reveal the front and back assembly of the deadbolt as well as the internal bolt. Remove the bolt and Replacing upvc door lock replace it with a new one to match your composite door lock replacement hardware. You'll need to remove the bolt from a setplate. After this is done then you need to chisel out the area for the strike plate that is on the door frame.

If your strike plate is not aligned, it's likely because the previous installer didn't properly mortise it or a weatherstripping came along and changed the strike's position. You will need to re-mortise the strikeplate and possibly even the deadbolt itself to fix this issue. Once this is completed Test the deadbolt by closing and locking it. Test the deadbolt by closing it and locking it once the bolt has been extended into the strike plate.

Knob

If a door knob is damaged, it can make your business or home less secure. It could also make it harder to open or close the door, making it an ideal idea to replace the knob.to hold it shut. The latch is operated either by a knob or handle on the inside of the door, or by a thumb-turn on the exterior. Deadbolts can be used to secure a latch and prevent intruders from breaking through the glass of the door. It can also guard against accidental or intentional closing by children or animals. You can choose to install the latch using either a single-cylinder deadbolt, or a double-cylinder deadbolt based on your preferred level of security.

Installing a deadbolt can be the same as installing a latch, however, there are some distinctions. First, measure the setback of the doorjamb by using a tape measure to make sure the new lock will fit. The setback is measured from the edge of the doorjamb up to the middle of the hole for the latch plate. A typical setback is 2 3/8 to 2 3/4 inches. If your setback is higher than that, you might need to purchase a latch that is longer from a locksmith or hardware store.

The next step is to drill an edge bore hole in the doorjamb for the latch plate. Use a chisel and make the mortise for the latch. Make sure that the depth is enough for the faceplate to be in line with the doorjamb. Tape the strikeplate in place to ensure it is positioned properly.

If the strike is set too high, the door could be kicked in or pressure put on it using a crowbar or tire iron. This can also cause the doorjamb to break. This can be corrected by drilling a new hole into the doorjamb, then removing the core from the previous one.

Installing the new strike plate is the last step. This can be done by screwing the new plate into the screw holes that are already in place. Use wood putty then to fill in any existing holes for screws or bolts that won't be used. Once the putty has dried, sand it to a smooth finish.

Strike

The metal piece that engages the deadbolt and latch when the door is shut is an electric strike. It is a vital part of the lock's security, as it prevents the door from opening and provides an additional barrier to force or kick. If a door is equipped with an electronic strike, it will be opened only by keys and the control unit that regulates the electrical impulses.

In the past, putting in an electronic strike required cutting a portion of a doorjamb to remove the latchbolt on a cylindrical lock from the pocket that is inside the strike. This modification is not just unattractive, but also exposes the mechanism of the latchbolt and keeper to uninitiated users.

Recently, a number of electric strike manufacturers have created a brand new electric strike called the "No Cut" strike that doesn't need cutouts in the doorjamb for operation. These strikes utilize a special design to allow the latchbolt and keeper to slide into the strike pocket without damaging the doorjamb faceplate.

The strike has an internal ramp that lifts the latchbolt and keeper whenever it receives an electrical signal from a reader or controller. The latchbolt and keeper are pushed higher on the ramp thanks to the retract. When the door is closed, the deadbolt is retracted and the latchbolt retracts into the keeper.

Installing an electric strike is an easy process, particularly if you are replacing upvc door lock the strike on a previous door. If you're upgrading an existing access control system to an electric strike, you must ensure that your new system is compatible. Also, you must make sure that the strike is properly wired to your access control system and that it is designed to operate in a fail-safe manner.

One way to protect against unauthorized access is to upgrade the strike on your doors to a high-quality strike plate. The plates utilize four to six three-inch screws instead of the two, three-fourth inch screws commonly used in regular strikes. These longer screws make breaking the frame to reach the thumb turn piece on a single deadbolt cylinder more difficult.
