Ten Replace Door Lock That Will Help You Live Better
How to Replace Door Locks

Door locks are your primary line of defense against unauthorized access to your home. Locks might need to be replaced because of signs of wear and tear or other events like 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 middle of the cylinder knob. This measurement will help you select the appropriate lock.

Deadbolt

If you want to ensure your door is safe from criminals, it's a great idea to install deadbolts. The bolt extends into the strike plate that is on the door frame when it's locked, making it much more difficult for a burglar to break in through the door. A single cylinder deadbolt can be activated with an exterior key on the side and a thumb turn device on the interior. Deadbolts are only effective when it's properly installed however.

You will first need to find out if the door 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 top of the door using the template included with your lock installation kit. Then, use the tape measure to determine how high the deadbolt should be. Then, mark this height on the side of the door and use a speed square to draw an even line across the mark you made for the bolt hole.

Then using a power drill, bore out the hole until it is on the opposite side of the door. It could take a few minutes. Then, sand the hole and the edge of the door so that it's smooth. It's also an excellent idea to paint or stain the door at this point.

Remove any screws that are visible from the deadbolt. This will reveal the rear and front assembly of the deadbolt as well as its bolt inside. Then unscrew the old bolt and replace it by a new one to match your door hardware. You'll need to remove the bolt from the setplate. After that then you need to cut out the space for the strike plate on the door frame.

If your strike plate is out of alignment, it could be because the previous installer didn't mortise it correctly or a weatherstripping changed the strike's location. You will need to re-mortise the strikeplate and perhaps even the deadbolt to fix this issue. Once you have completed this check the deadbolt by closing it and locking it. Test the deadbolt by closing and locking it after the bolt has been extended into the strike plate.

Knob

If the knob on your door wears out it could make your home or business less secure. It could also make opening or closing the door more difficult, so it's an ideal idea to replace the knob. It shouldn't take more than 30 minutes. You can use a screwdriver and pliers to take off the knob or handle that was previously used Be careful not to scratch any of the other components on 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 slide smoothly as you turn it. To ensure that it operates properly it is essential to select the knob and handle that are compatible with your doors. If you don't have a match, you'll need to buy a new doorknob and latch plate.

To begin the replacement process, look over the knob or handle to find what screws are holding it in place. If there are no screws then you can use the screwdriver to wedge the cover plate into the screws plate hidden behind it.

After removing the old knob take it apart and look for signs of rust and damage. If the knob is damaged or has scratches or marks, you'll have clean it. Otherwise it shouldn't require any major work.

Now is the time to put in the new one. You must first study the two knobs to make sure that you've selected the correct one for your door. You'll want to pick one with an extended rod that is designed to lock with the second knob's rod mechanism. After you've placed the new knob into the hole and then put it in the latch.

Thread the latch plate screws down, then test the spring by pressing down on it several times. The latch should spring back up every time. Then, put in the new knob and lock it with the rod mechanism on the previous 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 secure it closed. The latch can be operated by a handle or knob on the inside of the door, or by a thumb-turn on the outside. A latch can be secured by deadbolts to prevent thieves from breaking through the glass. It also provides protection from the accidental or deliberate closing of the door by pets or children. A latch can be set with a single cylinder deadbolt or a double cylinder deadbolt, according to the security level you prefer.

Installing a deadbolt is exactly the same as installing a latch but there are some differences. To make sure that the new lock will fit, first determine the setback of the doorjamb with an instrument such as a tape measure. The setback is measured from the edge of doorjamb up to the middle of the hole for the latch plate. Standard setbacks are 2 3/8 to 2. 3/4 inches. If your setback is larger it is possible to purchase a latch that is larger from a locksmith or hardware store.

The next step is to drill an edge bore hole in the doorjamb for the latch plate. Use a chisel and chisel the latch mortise. Make sure the hole's depth is enough for the faceplate to be flush with the doorjamb. Place the strikeplate on the floor to ensure it's placed properly.

If the strike is set too high, the door may be pushed in or pressure imposed on it using a crowbar or tire iron. This could cause the doorjamb's to crack. To fix this issue, the strike can be reduced by drilling a second hole into the doorjamb and cutting out the core of the previous hole.

Installing the new strike plate is the last step. front door locks replacement can be accomplished by fixing the new plate to the screw holes that are already in place. Then, use wood putty to cover the holes from the previous screws and the bolt hole that will not be used. Once the putty is dry then sand it to a smooth finish for an elegant finish.

Strike

The piece of metal that is inserted between the latch and deadbolt when the door is shut is an electric strike. It is an essential part of the lock's overall security because it prevents the door from opening and gives an additional barrier to force or kick. If a door is equipped with an electric strike, it will only be opened with a key or the control unit which controls the electrical impulses.


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

Recently, several electric strike manufacturers have developed an innovative type of electric strike, dubbed the "No Cut" strike that doesn't require cutouts in the doorjamb for operation. 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 lifts the latchbolt and keeper when it receives an electrical impulse from a reader or controller. The keeper and latchbolt are pushed higher on the ramp thanks to the retract. When the door is shut, the deadbolt remains in place and the latchbolt retracts into the keeper.

Installing an electronic strike is a straightforward process, particularly if you're replacing an existing strike. If you're planning to upgrade an access control system to an electric strike, it is important to ensure that the new system is compatible. It is also necessary to ensure that the strike is properly connected to your access control system and is configured to function in a fail-safe manner.

One method to guard against intrusions by thieves is to upgrade the strike on your doors to a heavy-duty strike plate. These plates use four to six three-inch screws instead of the two three-fourth inch screws commonly used in standard strikes. The longer screws make breaking the frame to reach the piece that turns the thumb on a single cylinder deadbolt more difficult.
