How to Replace Door Locks
The first security measure is your door lock. It will prevent unauthorized entry to your home. Locks might require replacement due to signs of wear and tear or other events such as moving into a new residence or a break-in.
You can determine the size of your cylinder by measuring the distance from the center of the knoblock cylinder to the adjustment screw. This measurement will enable you to buy the right lock.
Deadbolt
Installing a deadbolt can be a ideal way to secure your door against intruders. The bolt extends into the strike plate on the doorframe when it is locked, making it more difficult for a burglar to gain entry through the door. A single-cylinder deadbolt is activated by a key located on the exterior, and the thumb-turn mechanism located on the interior. A deadbolt will only work if it's installed correctly, though.
The first step is to determine 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 using the template that came with your lock installation kit. Then, use your tape measure to determine how high the deadbolt needs to be. Mark this height on the door edge. Use speedsquares to draw a straightline across the mark that you made for the bolthole.
Then using a power drill, bore through the hole until it is on the opposite side of the door. It could take a few minutes. Sand the hole and the edge of the door to make it smooth. It's also an excellent idea to paint or stain the door at this point.
Once the door is ready remove any screws that are visible on the existing deadbolt. This will reveal the front and back assemblies of the deadbolt as well as the bolt inside. Then, loosen the bolt and replace it with a new one that is compatible with your door hardware. The bolt is usually connected to a setplate which you'll need to unscrew. After that, you'll have to chisel the area on the door frame to accommodate the strike plate.
If your strike plate is not in alignment It could be due to the previous installer did not mortise it properly or that an installation of a weatherstripping altered the strike position. To fix this issue, you will need to remortise the strike plate and the deadbolt. After this is done check the deadbolt by closing and locking it. Be sure the bolt extends into the strike plate then test the key to make sure it opens and closes effortlessly.
replace door lock can make your home and business less secure if the door knob is damaged. It may make it more difficult to open or close the door, making it recommended to replace it. Replacing the knob is an easy DIY task that should not take more than 30 minutes to complete. You can use a screwdriver as well as pliers to take off the knob or handle that was previously used, but be careful not to damage any other parts on the door.
Before you start you'll need to spray WD-40 or a different dry lubricant onto the mechanism of the door knob. This will assist the new lock slide smoothly as you turn it. It's essential to select an excellent knob and handle that matches your doors currently in order to ensure proper operation. If you don't have a matching knob then you'll have to purchase an additional doorknob and latch plate.
To begin the replacement process, first look over the knob or handle to see 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 hidden screws plate and pop it off.
After you've removed the old knob, examine it for signs of damage or rust. You'll need to clean it up if there are any scratches or dents, but you shouldn't have to do anything if the knob is in good working order.
Now is the time to put in the new knob. It is important to first look over the two knobs to ensure that you've chosen the right one for the door. You'll need to pick one with an extending rod that will interlock with the rod mechanism of the second knob. Once you've positioned the new knob in the hole in the door and then carefully slide it into the latch.
Test the spring by pressing it repeatedly. The latch should then spring back up each time. Then, put in the new knob and lock it to the rod mechanism on the previous knob. Thread the long screws from the interior doorknob through the cylinder holes on the outside knob and lock it into its place.
Latch
A latch is a metallic piece that extends out into the doorjamb in order to hold it shut. It is operated by a handle or knob on the inside of the door, or a thumb turn on the exterior side of the door. A latch can be secured by deadbolts to stop intrusions from piercing the glass of the door. It also helps protect against accidental or intentional closing by animals or children. You can choose to install the latch using either a single-cylinder deadbolt or double-cylinder deadbolt based on the level of security.
Installing a latch involves the same steps like installing a deadbolt however, there are a few variations. To ensure that the new lock will fit first, you must determine the setback of the doorjamb using the tape measure. The setback is measured from the edge of the doorjamb up to the center of hole for the latch plate. Setbacks for standard latches are 2 3/8 to 2. 3/4 inches. If your setback is greater than that, you might need to purchase a latch that is longer from a hardware or locksmith store.
The next step is to drill an edge bore hole in the doorjamb to accommodate the latch plate. Use a chisel for chiseling out the latch mortise making sure it's large enough to allow the faceplate of the new latch to be flush with the doorjamb. Tape the strikeplate to the doorjamb to ensure that it's positioned correctly.
If the strike is set too high, the door could be kicked in or pressure applied to it using a crowbar or tire iron. This can also crack the doorjamb. To correct this, the strike can be lowered by drilling a new hole in the doorjamb and cutting out the core of the previous hole.
Installing the new strike plate is the final step. This can be done by fixing the new plate to the existing screw holes. Then, use wood putty to fill in the old screw holes and the bolt hole that is not used. After the putty has dried then sand it to a smooth finish for an elegant finish.
Strike
An electric strike is a metal piece that holds the deadbolt and latch are engaged when the door is closed. It is an essential part of the lock's overall security because it prevents the door from opening, and also provides additional resistance to force or kicking. If a door has been equipped with an electric strike, it can be opened with keys or the control unit that governs its electrical impulses.
Traditionally, installing an electric strike involved cutting out a portion of the doorjamb in order to remotely release a cylindrical lock's latchbolt from the pocket within the strike. This modification is not only ugly and unattractive, but also exposes the mechanism for the latchbolt and keeper to unauthorized users.
Recently, several electric strike makers have come up with a brand new electric strike dubbed the "No Cut" strike that doesn't require an opening in the doorjamb to function. They use a specific design that allows the latchbolt and keeper to slide into the pocket without causing damage to the faceplate of the doorjamb.
The strike is equipped with an internal ramp that raises the latchbolt and keeper when it receives a signal from a reader. The retraction of the keeper and latchbolt raises them on the ramp, locking the door. When the door is closed the deadbolt remains in place and the latchbolt retracts into the keeper.
Installing an electronic strike is a simple procedure, especially in the case of replacing an existing strike. If you're planning to upgrade an access control system to an electric strike, you need to ensure that the new system is compatible. Also, you must ensure that the strike is properly wired to your access control system and is configured for fail-safe operation.
One method to guard against unauthorized access is to upgrade the strike on your doors to a high-quality strike plate. These plates are fitted with four to six three-inch screws instead of the two three-fourth inch screws commonly employed in regular strikes. These screws are longer and make breaking the frame to reach the piece that turns the thumb on a single cylinder deadbolt more difficult.
