How to Replace Door Locks

Door locks are your first line of defense against unauthorized entry into your home. The signs of wear and tear and also instances like moving into a new home or burglaries, may trigger the need to replace your lock.

To begin, you must determine the size of your cylinder using the distance between the adjustment screw and the center of the knob lock cylinder. This measurement will help you select the appropriate lock.

Deadbolt

If you want to make sure your door is safe from burglars, it's a good idea to install deadbolts. The bolt extends into the strike plate on the doorframe when locked, making it more difficult for burglars to gain entry into the door. A single cylinder deadbolt can be activated using an exterior key on the side and a thumb turn part on the interior. A deadbolt is only effective when it's properly installed, though.

The first step is to find out if the door has a hole to install deadbolts or needs to be bored out. Utilizing the template included with the lock installation kit mark the location of the hole for the deadbolt on the door's surface. Use a tape measure to determine the height of the deadbolt. Mark this measurement on the door's edge. Use the speedsquare to draw a straight line across the mark that you made for the bolt hole.

Then, use a drill to bore out this spot until the hole extends to the other side of the door. It may take a while. Sand the hole and the door edge to smooth it. At this stage, it's a great idea to paint or stain your door.

Once the door is ready remove any screws visible on the existing deadbolt. This will reveal the front and rear assemblies of the deadbolt as well as its internal bolt. Then unscrew the old bolt and replace it with a new one to match your door hardware. The bolt is often connected to a setplate which you'll need to unbolt. Then, you'll need to chisel the door frame for the strike plate.

If your strike plate is not in alignment it could be because the previous installer did not mortise it properly or that an installation of a weatherstripping altered the strike's position. cost to replace upvc door lock mechanism is necessary to re-mortise your strike plate and possibly even the deadbolt to fix the issue. Close and lock the deadbolt when you have completed this step. Make sure the bolt extends into the strike plate then test the key to ensure it closes and opens smoothly.

Knob

It can make your home or business less secure if the door knob is damaged. It could make opening or closing the door more difficult, which is why it is a good idea for you to replace the knob. It shouldn't take you longer than 30 minutes. Use a screwdriver or pliers to remove any knobs or handles. Be careful not to harm 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 help the lock to move effortlessly as you turn it. It's important to use an excellent knob and handle that matches your doors currently in order to ensure that the lock is operating properly. If there's no match then you'll have to purchase a new doorknob and latch plate.

Before you begin the replacement process, examine the old knob to see what screws are holding it in place. If there aren't any screws you can use a screwdriver to insert between the cover plate and the plate with hidden screws and pop it off.

After taking the knob off, inspect it for signs of rust and damage. If the knob has any marks or scratches then you'll need clean it. Otherwise, it shouldn't require any major work.

Now is the time to put in the new one. It is important to first look over the two knobs to make sure that you are choosing the right one for the door. You'll need to choose one with an extending rod that is interlocked with the rod mechanism of the second knob. Once you've put the new knob into the hole, slide it into the latch.

Test the spring by pressing down on it repeatedly. The latch should spring back up each time. Then, put in the new knob and interlock it to the rod mechanism on the first knob. Thread the long screws from the doorknob's interior through the holes for cylinders on the exterior knob, and secure it in its place.

Latch

A latch is a piece of metal that extends through the door 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. A deadbolt is a device used to secure a latch and keep intruders from breaking through the glass of the door. It can also protect against accidental or intentional closing by children or animals. A latch can be installed with a single cylinder deadbolt or a double cylinder deadbolt, according to the security level you prefer.


Installing a deadbolt can be the same as installing a latch, but there are some differences. First, you must measure the setback of the doorjamb by using a tape measure to be sure the new lock will fit. The setback is the distance between the edge of the doorjamb to the middle of the hole for the faceplate for the latch. The standard setback is 2 3/8 to 2 3/4 inches. If you have a greater setback, you may need to purchase a more substantial latch from a hardware shop or locksmith.

Then, drill a hole for the latch plate in the edge of the doorjamb. Use a chisel to chisel out the mortise of the latch making sure it's large enough to allow the faceplate of the new latch to sit in a flush position with the doorjamb. Place the strike plate in place to make sure it's in the right position.

If the strike is too high, you could push the door back or apply pressure using a tire iron or crowbar. This can also cause the doorjamb's to crack. This can be fixed by drilling a new hole through the doorjamb, then cutting the core from the hole that was previously made.

The final step is to put in the new strike plate, which can be done by screwing it over the existing screw holes. Utilize wood putty to fill in any existing screw holes or bolt holes which aren't going to be used. Once the putty is dry then sand it to a smooth finish for an elegant finish.

Strike

An electric strike is the metal part where the deadbolt and latch are engaged when the door is closed. It is a vital part of the lock's overall security because it stops the door from opening and gives an additional barrier to force or kick. If a door is equipped with an electric strike, it can only be opened using a key or the control unit that governs its electrical impulses.

Traditionally, installing an electric strike involved cutting out a portion of the doorjamb to release the latchbolt of a cylindrical lock from the pocket in the strike. This change can be an issue when it comes to the appearance of an opening and also exposes the latchbolt and keeper mechanism to unauthorized users.

Recently, several electric strike manufacturers have created a new type of electric strike called the "No Cut" strike that doesn't require cutouts in the doorjamb to function. These strikes utilize a special design that allows the latchbolt and keeper to slide into the strike pocket without damaging the faceplate of the doorjamb.

The strike is equipped with an internal ramp that raises the latchbolt and keeper whenever it receives an electrical signal from a controller or reader. The keeper and latchbolt are lifted higher up the ramp by the retraction. When the door is closed the deadbolt remains extended and the latchbolt is retracted into the keeper.

Installing an electric strike is an easy task, especially if you are replacing the strike on a previous door. If you're planning to upgrade an access control system to an electric strike, it is important to make sure that the new system is compatible. It is also necessary to ensure that the strike is connected to your access control system and that it is designed to operate in a fail-safe manner.

One way to protect against access by unauthorized persons is to upgrade the strike on your doors to a high-quality strike plate. These plates use up to six screws of three inches instead of the standard two screws of three-fourths inches. These screws are longer, making it harder for people to break the frame and reach inside to turn the thumb turn part of a single deadbolt cylinder.
