How to Replace Door Locks
Door locks are the first protection against unauthorised access to your home. Locks might need to be replaced due to wear and tear or other events such as moving into a new residence or a break-in.
To begin, you must determine your cylinder size by measuring the distance between the adjustment screw and the center of the knob lock cylinder. This measurement will assist you buy the lock that is right for you.
Deadbolt
If you want to ensure your door is secure from intruders, it's a good idea to install deadbolts. When the bolt is extended into the strike plate of the doorframe it makes it harder for an intruder to get through the door. A single-cylinder deadbolt can be activated by a key located on the exterior, and a thumb-turn piece located on the interior. Deadbolts can only function only if it is correctly installed.
First, you will need to determine if the door has a hole to install a deadbolt or if it needs to be bored out. Mark the position of the hole for the deadbolt on the surface of the door using the template that came with your lock installation set. Then, you can use your tape measure to determine how high the deadbolt should be. Mark this measurement on the door's edge, and then use a speedsquare to draw a straight line across the mark that you made to mark the bolt hole.
Then, using an electric drill, bore out the hole until it is on the opposite side of the door. It could take a few minutes. Sand the hole and the door edge to smooth it. At this moment, it's a good idea also to stain or paint your door.
Once the door is ready take off any screws visible on the deadbolt. This will reveal the front and rear assemblies of the deadbolt as well as its bolt inside. Then, remove the bolt and replace it with an alternative bolt that matches the door hardware. You'll need to remove the bolt from a setplate. After this, you'll need to chisel the door frame for the strike plate.
If your strike plate isn't aligned properly, it's likely because the previous installer didn't properly mortise it or a weatherstripping popped up and changed the strike's position. To fix this problem, you will need to remortise the strike plate as well as the deadbolt. Once you have completed this Test the deadbolt by closing and locking it. Test the deadbolt by closing and locking it once the bolt has been extended into the strike plate.
Knob
It can make your home and business less secure when the door knob is damaged. It can make opening or closing the door more difficult, which is why it is recommended to replace it. It shouldn't take longer than 30 minutes. Use pliers or a screwdriver to remove any knobs or handles. Be cautious not to scratch other components of the door.
Spray WD-40, or a different dry lubricant, on the mechanism of your door knob before you begin. This will assist the new lock to slide smoothly when you turn it. To ensure proper operation it is important to select the knob and handle that match the doors you already have. If you don't already have a matching doorknob then you'll have to purchase a replacement.
Before you begin replacing the knob, take a look at the knob that was previously used to see what screws are holding it in place. If there aren't any screws then you can use the screwdriver to secure the cover plate between the screws plate that is hidden.
After you have removed the knob take it apart and look for evidence of damage or rust. You'll have to scrub it off if there are any scratches or marks however you don't need to do anything major when the knob is in good working order.
Install the new knob. First, examine the new knobs to ensure you're selecting the correct one for your door. You'll need to choose one with an extended rod that is designed to lock with the rod mechanism on 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 downwards and then test the spring by pressing down on it repeatedly. The latch should then spring back up each time. Then, you can install the new knob and connect it with the rod mechanism of the first knob. Then, thread the other long screws from the knob's interior through the cylinder hole on the doorknob outside and secure it.
Latch
A latch is a piece of metal that extends through the door jamb to keep it shut. It is operated by a knob or handle on the interior side of the door or by a thumb turn on the outside side of the door. A deadbolt is a device used to secure a latch and keep burglars from piercing the glass of the door. It can also guard against intentional or accidental closing by children or animals. You can install a latch with either a single-cylinder deadbolt, or a double-cylinder deadbolt based on your preferred level of security.
Installing a deadbolt is the same as installing a latch but there are some differences. First, measure the setback of the doorjamb by using an instrument to make sure 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. A standard setback is 2 3/8 to 2 3/4 inches. If you have a larger setback, you might need to purchase a longer latch at a hardware store or locksmith.
Then, you'll need to make a hole for the latch plate in the doorjamb's edge. Utilize a chisel to smooth out the mortise for the latch and ensure it's deep enough for the faceplate of the new latch to sit flush with the doorjamb. Tape the strikeplate in place to ensure that it's positioned properly.
If the strike is placed too high, the door can 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 through the doorjamb, and then chiseling out the core of the hole that was previously drilled.
click here for info is to install the new strike plate, which can be done by screwing it 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. After the putty is dry, sand it to an even finish.
Strike
An electric strike is the metal piece that holds the latch and deadbolt engage when the door is closed. It is a crucial component of the security of a lock, because it keeps the door shut and also provides additional resistance to force or kicks applied to the door. If a door comes with an electronic strike, it will be opened only with keys and the control unit that controls its electrical impulses.
Traditionally the installation of an electric strike involved cutting out a portion of the doorjamb in order to release the latchbolt of a cylindrical lock from the pocket within the strike. This modification is not only ugly however, it also exposes the mechanism for the latchbolt and keeper to uninitiated users.
Recently, a variety of electric strike manufacturers have come up with a "No Cut" kind of strike that does not require a cutout in order to operate. The strikes have a unique design that allows the latchbolt and keeper to slide into the pocket without damaging the doorjamb's faceplate.
The strike is equipped with an internal ramp that raises the keeper and latchbolt when it receives an electrical signal from a controller or reader. The keeper and latchbolt are pushed up the ramp due to retraction. When the door is shut, the deadbolt is retracted and the latchbolt retracts in the keeper.
Installing an electronic strike is a simple procedure, especially in the case of replacing an existing strike. However, if you are upgrading to an electric strike to use with an access control system, you will have to ensure that your new system is compatible with the type of lock you have installed. Also, you must ensure that the strike is properly connected to your access control system and set up to function in a fail-safe manner.
One way to safeguard against intrusions by thieves is to upgrade the strike on your doors to a robust strike plate. These plates are fitted with 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 deadbolt cylinder more difficult.
