Deadbolt
Installing a deadbolt is a great way to secure your door against intruders. The bolt extends into the strike plate on the doorframe when it is locked, making it much more difficult for a burglar to break in through the door. A single cylinder deadbolt can be activated using an exterior key on the side and a thumb turn piece on the interior. A deadbolt will only work if it is installed correctly.
First, you will need to find out if the door has a hole for deadbolts or requires drilling. Mark the location of the hole for the deadbolt on top of the door by using the template supplied with your lock installation kit. Then, you can use your tape measure to determine how high the deadbolt should be. Mark this measurement on the
door lock replacement near me's edge, and then use speedsquares to draw a straightline across the mark that you made to mark the bolt hole.
Then, using the power drill, drill out the hole until it is on the opposite side of the door. This may take a while. Sand the hole and the edge of the door to make it smooth. It's also a good idea to stain or paint the door at this point.
When the door is open remove any screws visible on the deadbolt. This will reveal the back and front assemblies of the deadbolt and also the bolt that is inside. Then, remove the bolt and
replace lock on patio door it by a new one to match the door hardware. You will need to unscrew the bolt from the 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 position. You'll need to re-mortise your strike plate and perhaps even the deadbolt to fix this issue. Close and lock the deadbolt when you've completed this process. Make sure that the bolt is extending into the strike plate, and then test the key to make sure it closes and opens easily.

Before you begin, you'll want to spray WD-40 or a different dry lubricant onto the mechanism of the knob on your door. This will allow the new lock slide smoothly when you turn it. To ensure proper operation, it's important to choose the knob and handle that match your existing doors. If you don't have a matching knob then you'll have to purchase a new doorknob and latch plate.
To begin the replacement process, first look over the knob or handle to see the screws that hold it in place. If there aren't any screws you can make use of a screwdriver and wedge it between the cover plate and the hidden screws plate and remove it.
After taking the knob off take it apart and look for signs of rust and damage. You'll need to clean it off if there are any scratches or dents however, you shouldn't need to do anything major If the knob is in good shape.
Now it's time to install the new one. You must first study the two knobs to ensure that you've selected the right one for the door. You'll need to pick one with an extender rod that is interlocked with the rod mechanism of the other 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 each time. Install the second knob and lock it to the rod mechanism of the first knob. Attach the other long screws from the interior knob through the cylinder hole on the doorknob outside and secure it.
Latch
A latch is a metal piece that extends into the
upvc door lock replacement jamb to keep it closed. The latch can be operated via a knob or handle located inside the door, or by a thumb-turn on the outside. The latch can be secured by a deadbolt to keep intrusions from piercing the glass of the door. It also offers protection from the accidental or deliberate closing of the door by pets or children. The latch can be fitted with one cylinder deadbolt or double cylinder deadbolts according to the security level you prefer.
Installing a deadbolt can be the same as installing a latch, but there are some differences. First, measure the setback of the doorjamb using a tape measure to be sure the new lock will fit. 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. Setbacks for standard latches are 2 3/8 to 2. 3/4 inches. If you have a higher setback, you may need to purchase a larger latch at a hardware store or locksmith.
The next step is to drill an edge bore hole in the doorjamb for the latch plate. Utilize a chisel to chisel the latch mortise. Make sure the hole's depth is enough to allow the faceplate to be flush with the doorjamb. Put the strike plate into place to make sure it is positioned correctly.
If the strike is too high, you can kick the door in or apply pressure using the tire iron or crowbar. This can also crack the doorjamb. This can be repaired by drilling a new hole through the doorjamb and then chiseling the core out of the old one.
The last step is to install the new strike plate, which can be accomplished by screwing it in place over the existing screw holes. Then you can use wood putty to cover the screw holes that were previously used 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 is inserted between the latch and deadbolt 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 level of resistance to force or kick. If a door comes with an electronic strike, it will be opened only with a key and the control unit that regulates the electrical impulses.
Traditionally the installation of an electric strike meant cutting a small portion of the doorjamb to remotely release the latchbolt of a cylindrical lock from the pocket of the strike. This is not only undesirable however, it also exposes the latchbolt mechanism and keeper to unauthorized users.
Recently, several electric strikes manufacturers have come up with a "No Cut" kind of strike that doesn't require a cutout to operate. The strikes have a unique design that allows the latchbolt and keeper to slide into the pocket without causing damage to the doorjamb's faceplate.
The strike has an internal ramp that raises the latchbolt and keeper whenever it receives an electrical impulse from a reader or controller. The latchbolt and keeper are lifted higher up the ramp due to retraction. When the door is closed the deadbolt remains in place and the latchbolt is retracted into the keeper.
Installing an electronic strike is a straightforward procedure, particularly if you're
replacing upvc door lock mechanism an existing strike. If, however, you are upgrading to an electric strike in an access control system, you will be required to ensure that the new system is compatible with the type of lock you've chosen to install. Also, you must ensure that the strike is properly connected to your access control system and that it is designed to operate in a fail-safe manner.
One method to guard against intrusions by thieves is to upgrade the strike on your doors to a heavy-duty strike plate. The plates utilize four to six screws of three inches instead of the two three-fourth inch screws typically employed in regular strikes. These longer screws make breaking the frame to reach the thumb turn piece on a single cylinder deadbolt more difficult.
