Why You Should Be Working With This Replace Door Lock
How to Replace Door Locks

Door locks are your primary protection against unauthorised access to your home. Signs of wear and tear, and even instances such as moving into a new home or break-ins, can necessitate the need to replace your lock.

To begin, determine the size of your cylinder using the distance between the adjustment screw and the middle of the cylinder knob. This measurement will enable you to purchase the correct-sized lock.

Deadbolt

Installing a deadbolt is a excellent way to protect your door from burglars. The bolt extends into the strike plate that is on the doorframe when it is locked, making it much more difficult for a burglar to gain entry through the door. A single-cylinder deadbolt can be activated by a key located on the exterior and a thumb-turn device located on the interior. A deadbolt is only effective when it's properly installed however.

First, you must determine if the door has an existing hole for a deadbolt or if you need to bore it out. Mark the position of the hole for the deadbolt on the surface of the door using the template that came with the lock installation set. Then, use the tape measure to determine the height the deadbolt needs to be. Then, mark the height on the edge of the door. Use the speed square to draw a straight line across the mark you made for 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 some time. Sand the hole and the door edge to make it smooth. At this moment, it's a good idea to paint or stain your door.

Remove any screws that are visible from the deadbolt. This will reveal the back and front assemblies of the deadbolt and also the bolt that is inside. Then, unscrew the bolt and replace it with a brand new bolt that matches the door hardware. The bolt is typically connected to a setplate that you need to unbolt. After this is done it is time to chisel the area for the strike plate on the door frame.

If your strike plate is not in alignment it could be because the previous installer didn't mortise it correctly or a weatherstripping has changed the strike's location. You will need to re-mortise the strikeplate and possibly even the deadbolt itself to fix the issue. After this is done, test the deadbolt by closing it and locking it. Make sure the bolt is extending into the strike plate then test the key to make sure it closes and opens easily.

Knob

If a door knob is damaged, it can make your business or home less secure. It can also make it harder to open or close the door, which is why it's an ideal idea to replace the knob. Replacing knobs is an easy DIY project and shouldn't take less than 30 minutes to complete. Use a screwdriver or pliers to remove any knobs or handles. Be careful not to harm the other components of the door.

Spray WD-40 or another dry lubricant on the mechanism of your door knob prior to you begin. This will allow the new lock move smoothly when you turn it. It is essential to choose an excellent knob and handle that match your current doors to ensure that the lock is operating properly. If there's no match you'll need to purchase an additional doorknob and latch plate.

Before you begin replacing the knob, take a look at the knob that was previously used to determine which 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 plate with hidden screws and pop it off.

After removing the old knob take it apart and look for signs of rust and damage. If the knob has any dents or marks it's time clean it. Otherwise it shouldn't require any major work.

Now it's time to install the new one. Before you do that, look over the knobs you've chosen to ensure that you're choosing the right one for your door. You'll need to select one with an extending rod that is interlocked with the rod mechanism of the second knob. Once you've positioned the new knob over the door's hole and then carefully place it in the latch.

Thread the latch plate screws downwards, then test the spring by pressing down repeatedly. The latch should spring up each time. Then, put in replacement upvc door lock and lock it with the rod mechanism on the first knob. Attach the other long screws from the knob's interior through the hole for the cylinder on the doorknob outside and lock it in place.

Latch

A latch is a metal piece that extends out into the doorjamb to keep it shut. The latch is operated either by a knob or handle on the interior of the door, or a thumb-turn on the exterior. The latch can be secured by a deadbolt to keep intruders from breaking in through the glass of the door. It also offers protection from accidental or intentional closing of the door by children or pets. A latch can be set with single cylinder deadbolts or a double cylinder deadbolt, according to the security level you prefer.

Installing a latch requires the same steps similar to installing a deadbolt however there are some distinctions. First, you must measure the setback of the doorjamb with a tape measure to be sure the new lock will fit. The setback is the distance between the edge of the doorjamb, to the center of the hole to accommodate the faceplate of the latch. Setbacks for standard latches are 2 3/8 to 2. 3/4 inches. If you have a larger setback, you may have to purchase a larger latch from a hardware shop or locksmith.

The next step is to drill an edge bore hole through the doorjamb to accommodate the latch plate. Use a chisel for chiseling out the mortise for the latch and ensure it's deep enough to allow the faceplate of the new latch to sit in a flush position with the doorjamb. Tape the strikeplate to the doorjamb to ensure it is positioned properly.

If the strike is too high, you can push the door back or apply pressure using an iron tire or crowbar. This could cause the doorjamb's to crack. This can be corrected by drilling a new hole through the doorjamb, then removing the core from the previous one.


The last step is to mount the new strike plate, which is done by screwing it over the screw holes that are already in place. Then apply wood putty to cover the screw holes that were previously used and the bolt hole that is not used. After the putty is dry, 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 an important part of the overall security of a lock because it helps keep the door shut and also provides additional resistance to kicking or force applied to the door. If a door comes with an electronic strike, it will be opened only by keys and the control unit that regulates its electrical impulses.

Traditionally, installing an electric strike required cutting out a portion of the doorjamb in order to release the latchbolt of a circular lock from the pocket of the strike. This modification is not just ugly, but also exposes the mechanism for the latchbolt and the keeper to intruders.

Recently, a number of electric strike manufacturers have created a "No Cut" type of strike that doesn't require a cutout for operation. These strikes utilize a special design that allows the keeper and latchbolt to slide into the strike pocket without damaging the faceplate of the doorjamb.

The strike is equipped with an internal ramp that lifts the latchbolt as well as the keeper when it receives a signal from the reader. The latchbolt and keeper are lifted higher up the ramp by the retraction. When the door is shut the deadbolt remains in at a lower position and the latchbolt retracts into the keeper.

Installing an electronic strike is a simple procedure, particularly if you're replacing an existing strike. However, if you are upgrading to an electric strike for an access control system, you'll have to ensure that your new system is compatible with the kind of lock you've installed. You will also have to ensure that the strike is connected to your access control system and is set up to function in a fail-safe manner.

Upgrade your strike plates to high duty strike plates to block the entry of unauthorized persons. These plates use four to six three-inch screws instead of the two three-fourth inch screws commonly used in standard strikes. These screws are longer and make breaking the frame to reach the thumb turn piece on a single deadbolt cylinder more difficult.
