When the bolt is extended into the strike plate of the doorframe it makes it much more difficult for an intruder through the door. upvc door replacement lock can be activated by a key on the exterior side and a thumb turn device on the interior. A deadbolt is only effective if it's installed correctly, though.
First, you will need to find out if the door has a hole to install deadbolts, or if it requires drilling. Mark the location of the hole to install the deadbolt on the surface of the door using the template included with the lock installation set. Use a tape measure to determine the height of the deadbolt. Mark this height on the door edge. Use a speedsquare to draw a straight line across the mark you made to mark the bolt hole.
Then, use a drill to bore out this spot until the hole is on the opposite side of the door. This may take a while. Then, sand down the hole and along 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 visible screws from the deadbolt. This will reveal the back and front assemblies of the deadbolt and also the bolt that is inside. Then unscrew the old bolt and replace it with the new bolt to match your door hardware. The bolt is often connected to a setplate that you need to unscrew. After that, you will need to cut out the space for the strike plate on the door frame.
If your strike plate is not aligned it's likely that the previous installer didn't mortise it correctly or a weatherstripping was installed and changed the strike position. You'll need to re-mortise the strikeplate and possibly even the deadbolt itself to fix the issue. Close and lock the deadbolt once you have completed this step. Test the deadbolt by closing and locking it once the bolt has been extended into the strike plate.

It is essential to choose the best knob and handle that match your doors currently in order to ensure proper operation. If you don't have a match you'll need to purchase an additional doorknob and latch plate.
To begin the replacement process, first look at the knob or handle to determine what screws are holding it in place. If there aren't any screws, you can use the screwdriver to insert the cover plate between the hidden screws plate.
After you have removed the knob take it apart and look for signs of rust and damage. You'll need to clean it up if there are any scratches or dents however you don't need to do anything if the knob is in good working order.
Install the new knob. Before you do that, look over the two new knobs to ensure that you're choosing the right one for your door. You'll need to select one with an extender rod that will interlock with the rod mechanism of the second knob. After you've placed the new knob in the hole then slide it into the latch.
Test the spring by pressing down on it repeatedly. The latch should then spring back up every time. Then, put in the new knob and lock it with the rod mechanism on the previous knob. Attach the other long screws from the knob's interior through the hole in the cylinder of the exterior doorknob and secure it.
Latch
A latch is a piece metal that extends through the doorjamb to hold it shut. The latch is operated by a handle or knob located inside the door, or a thumb-turn on the outside. The latch can be secured with deadbolts to stop intruders from breaking in through the glass of the door. It can also protect against intentional or accidental closing by animals or children. A latch can be set with single cylinder deadbolts or double cylinder deadbolts depending on the security level you prefer.
Installing a deadbolt is the same as installing a latch, however there are some differences. First, you must measure the setback of the doorjamb by using a tape measure to make sure that the new lock will fit. The setback is measured from the edge of the doorjamb up to the center of hole for the latch plate. Standard setbacks are 2 3/8 to 2. 3/4 inches. If your setback is greater, you may need to purchase a latch that is longer from a hardware or locksmith store.
The next step is to drill an edge bore hole into the doorjamb for the latch plate. Use a chisel to chisel out the latch mortise, making sure it's deep enough to allow the faceplate of the new latch to sit flush with the doorjamb. Tape the strikeplate to the doorjamb to ensure it's placed correctly.
If the strike is placed too high, the door may be pushed into or pressure put on it using a crowbar, or tire iron. This could also cause cracks in the doorjamb. To correct this, the strike could be lowered by drilling a new hole into the doorjamb and chiseling out the core of the old hole.
The final step is to mount the new strike plate which can be done by screwing it over the existing screw holes. Use wood putty afterwards to fill in any old bolt holes or screw holes that aren't being used. When the putty is dry, sand it smooth for professional results.
Strike
The piece of metal that connects the latch and deadbolt when the door is closed is an electric strike. It is a vital part of the lock's overall safety, as it prevents the door from opening, and also provides an additional level of resistance to force or kick. If a door has been equipped with an electric strike, it can be opened with keys or the control unit that controls the electrical impulses.
Traditionally the installation of an electric strike involved cutting a small portion of the doorjamb to release the latchbolt of a circular lock from the pocket of the strike. This is a drawback in terms of the appearance of openings, and it also exposes the latchbolt and keeper mechanism to unauthorized users.
Recently, a number of electric strike manufacturers have come up with a "No Cut" kind of strike that doesn't require a cutout for operation. These strikes have a unique design to allow the keeper and latchbolt to slide into the strike pocket without marring the doorjamb faceplate.
The strike has an internal ramp that lifts the latchbolt and keeper whenever it receives an electrical signal from a controller or reader. The latchbolt and keeper are lifted higher up the ramp by the retract. When the door is closed the deadbolt remains extended and the latchbolt is retracted into the keeper.
Installing an electronic strike is a straightforward procedure, particularly when you're replacing an older strike. If you're planning to upgrade an existing access control system to an electric strike, it is important to ensure that the new system is compatible. Also, you must ensure that the strike is connected to your access control system and is configured to function in a safe manner.
One way to safeguard against unauthorized access is to upgrade the strike on your doors to a robust strike plate. The plates utilize four to six three-inch screws instead of the two three-fourth inch screws typically used in standard strikes. These longer screws make it difficult for someone to break the frame and then reach inside to turn the thumb turn part of a single deadbolt cylinder.
