How to replace door lock [my sources] Door Locks

Door locks are your first line of defense against unauthorized entry into your home. Locks may require replacement door locks due to wear and tear, or other situations like moving into a new residence or a burglary.

Deadbolt

If you want to ensure your door is secure from burglars, it's a good idea to install a deadbolt. The bolt extends into the strike plate on the doorframe when locked, making it more difficult for burglars to break in through the door. A single-cylinder deadbolt is activated with a key on the exterior and a thumb-turn device located on the interior. A deadbolt is only effective when it's properly installed, though.

It is first necessary to determine whether the door already has an existing hole for a deadbolt or if you'll need to drill it. Mark the location of the hole for the deadbolt on the surface of the door using the template included with the lock installation set. Utilize your tape measure to determine the height of the deadbolt. Mark this height on the door edge and use the speedsquare to draw a straightline across the mark you made to mark the bolt hole.

Then by using the power drill, drill through the hole until it reaches 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 stain or paint the door at this point.

Remove any screws that are visible from the deadbolt. This will reveal both the rear and front assembly of the deadbolt and its bolt inside. Remove the bolt and replace it with an alternative bolt that matches your door hardware. The bolt is usually connected to a set plate, which you will have to remove. After this, you'll need to chisel the door frame to accommodate the strike plate.

If your strike plate is misaligned It's likely that the previous installer didn't properly mortise it or a weatherstripping was installed and changed the strike's position. You will 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. Be sure the bolt extends into the strike plate, and then test the key to ensure it closes and replace door Lock opens easily.

It is essential to choose the best knob and handle that is compatible with your doors currently in order to ensure proper operation. If you don't have a doorknob that matches then you'll have to purchase a replacement.

Before you begin replacing upvc door lock mechanism the knob, look over the knob you replaced to determine what screws are that are holding it in place. If there aren't screws to hold it in place, you can use a screwdriver to wedge the cover plate between the screws plate that is hidden.

After you've removed the old knob, examine it for any signs of rust or damage. If the knob shows any scratches or marks it's time clean it. Otherwise it shouldn't need any major work.

It's time to install the new one. First, examine the new knobs to make sure that you're selecting the correct one for your door. You'll need to choose one with an extended rod that locks with the rod mechanism of the other knob. After you've placed the new knob in the hole, slide it into the latch.

Thread the latch plate screws down, then test the spring by pushing down on it several times. The latch should then spring back up each time. Next, install the other new knob and connect it with the rod mechanism on the first knob. Attach the other long screws from the interior knob through the hole in the cylinder of the doorknob on the outside and lock it in place.

Latch

A latch is a piece metal that extends into the doorjamb to hold it shut. It is operated by a knob or handle on the inside of the door, or a thumb turn on the outside side of the door. The latch can be secured using a deadbolt to keep intrusions from piercing the door's glass. It also helps protect against intentional or accidental closing by animals or children. A latch can be installed using one cylinder deadbolt or double cylinder deadbolts depending on the security level you prefer.

Installing a latch follows the same steps like installing a deadbolt however there are some distinctions. To ensure that the new lock will fit first, you must measure the setback on the doorjamb with an instrument such as a tape measure. The setback is the distance between the edge of the doorjamb, to the center of the hole that will be used for the faceplate of the latch. Setbacks for standard latches are 2 3/8 to 2. 3/4 inches. If you have a greater setback, you might need to purchase a larger latch from a hardware store or locksmith.

Then, drill a hole for the latch plate at the doorjamb's edge. Utilize a chisel to make the mortise for the latch. Make sure that the depth is sufficient for the faceplate to be in line with the doorjamb. Place the strike plate in place to make sure it's placed correctly.

If the strike is set too high, the door can be pushed in or pressure applied to it using a crowbar, or tire iron. This can also crack the doorjamb. This can be repaired by drilling a new hole in the doorjamb and then cutting the core from the previous one.

The final step is to mount the new strike plate, which can be accomplished by screwing it over the screw holes that are already in place. Use wood putty afterwards to fill in any existing holes for screws or bolts that won't be used. After the putty has dried, sand it smooth for professional results.

Strike

The piece of metal that connects the latch and deadbolt when the door is closed is an electric strike. It is a vital part of the lock's overall safety, as it prevents the door from opening and gives an additional barrier to force or kicking. If a door is equipped with an electric strike, it can only be opened with keys or the control unit that controls its electrical impulses.

In the past, installing an electronic strike was as simple as cutting off a part of a doorjamb to release the latchbolt of a cylindrical lock from the pocket that is inside the strike. This is not only undesirable, but also exposes the mechanism for the latchbolt and keeper to uninitiated users.

Recently, a number of electric strike manufacturers have created a "No Cut" kind of strike that does not require a cutout in order to operate. These strikes use a special design that allows the latchbolt and keeper to slide into the pocket without causing damage to the doorjamb's faceplate.

The strike is equipped with an internal ramp that raises the keeper and latchbolt when it receives an electrical impulse from a reader or controller. The latchbolt and keeper are lifted higher up the ramp due to retract. When the door is closed the deadbolt is retracted and the latchbolt retracts into the keeper.

Installing an electronic strike is a simple procedure, particularly in the case of replacing a patio door lock an existing strike. If, however, you are upgrading to an electric strike for an access control system, you'll need to make sure your new system is compatible with the kind of lock you've installed. It is also necessary to make sure that the strike is properly connected to your access-control system and is configured to operate in a fail-safe way.

Upgrade your strike plates to high duty strike plates to block unauthorized entry. These plates are fitted with four to six screws of three inches instead of the two three-fourth inch screws that are typically used in standard strikes. These longer screws make breaking the frame to reach the piece that turns the thumb on a single deadbolt for a cylinder more difficult.
