The Story Behind Replace Door Lock Will Haunt You Forever!
How to Replace Door Locks
Door locks are your primary line of defense against unauthorized entry into your home. Locks may require replacement due to wear and tear, or other situations like moving into a new home or a break-in.
To begin, determine the size of your cylinder by measuring the distance between the adjustment screw and the middle of the cylinder knob. This measurement will allow you to purchase the appropriate lock.
Deadbolt
If you want to make sure your door is secure against criminals, it's a great idea to install a deadbolt. 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 using a key on the exterior, and a thumb-turn piece situated inside. Deadbolts will only work when it is properly installed.
First, you must find out if the door has an existing hole for a deadbolt or if you'll need to drill it out. Mark the position of the hole for the deadbolt on top of the door by using the template supplied with your lock installation set. Use a tape measure to determine the height of the deadbolt. Then, mark this high point on the outside of the door. Use a speed square to draw straight lines across the mark you made for the bolt hole.
Next, use a power drill to drill this spot until the hole extends to the other side of the door. It may take a while. Then, sand the hole and the edges of the door until it is smooth. It's also a good idea to paint or stain the door at this point.
When the door is open remove any screws that are visible on the existing deadbolt. This will reveal the front and rear assembly of the deadbolt, as well as its bolt inside. Then, loosen the bolt and replace it with a new one that matches the door hardware. The bolt is usually connected to a setplate which you'll have to remove. 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 failed to mortise it correctly or a weatherstripping changed the strike's position. To fix this issue you'll need to remortise the strike plate as well as the deadbolt. Close and lock the deadbolt once you've completed this step. 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 is worn out, it can make your home or business less secure. It could make it more difficult to open or close the door, so it's recommended to replace it. Replacing a knob is a relatively easy DIY project and shouldn't take more than 30 minutes to complete. You can use a screwdriver and pliers to get rid of the old knob or handle, but be careful not to harm any other parts on the door.
Before starting you'll need to spray WD-40 or another dry lubricant onto the mechanism of the knob on your door. This will help the new lock slide effortlessly as you turn it. It is essential to choose an excellent knob and handle that matches your current doors to ensure proper operation. If you don't have a matching knob then you'll have to purchase an additional doorknob and latch plate.
To begin the replacement process, first look over the knob or handle to find what screws hold it in place. If there aren't screws to hold it in place, you can use a screwdriver to secure the cover plate into the screws plate hidden behind it.
After you've removed the old knob, examine it for any signs of rust or damage. It's important to clean it off if there are any marks or dents however, you shouldn't need to do anything when the knob is in good condition.
Install the new knob. It is important to first look over the two knobs in order to make sure that you are choosing the right one for the door. You'll want to pick one with an extended rod that's designed to lock into the second knob's rod mechanism. After you've placed the new knob over the door's hole, carefully place it in the latch.
Test the spring by pressing down on it repeatedly. The latch should then spring back up every time. Then, put in the new knob and interlock it to the rod mechanism on the first knob. Thread in the other long screws from the knob's interior through the cylinder hole on the doorknob outside and lock it in place.
Latch
A latch is a steel piece that extends out into the doorjamb in order to hold it shut. The latch can be operated via a knob or handle located inside the door, or a thumb-turn on the exterior. A latch can be secured by deadbolts to prevent intrusions from piercing the glass of the door. It also helps protect against intentional or accidental closing by children or animals. The latch can be fitted with one cylinder deadbolt or double cylinder deadbolts, according to the security level you prefer.
Installing a latch involves the same steps similar to installing a deadbolt however, there are a few variations. To make sure that the new lock is compatible, first take a measurement of the setback on the doorjamb with an instrument such as a tape measure. The setback is the distance from the edge of the doorjamb to the center of the hole that will be used for the faceplate of the latch. A typical setback is 2 3/8 to 2 3/4 inches. If you have a greater setback, you may need to purchase a larger latch from a hardware store or locksmith.
The next step is to drill an edge bore hole into the doorjamb to accommodate the latch plate. Use a chisel and make the mortise for the latch. Make sure that the depth is enough to allow the faceplate to be in line with the doorjamb. Place the strike plate in place to ensure that it's in the right position.
If the strike is too high, you could kick the door in or apply pressure using an iron tire or crowbar. This could also cause cracks in the doorjamb. To remedy this, the strike can be lowered by drilling a new hole in the doorjamb and chiseling out the core of the old hole.
The final step is to install the new strike plate, which can be accomplished by screwing it over the existing screw holes. Use wood putty then to fill in any old holes for screws or bolts that won't be used. Once the putty is dry, sand it smooth for an elegant finish.
Strike
An electric strike is the metal part where the latch and deadbolt engage when the door is shut. It is an important part of the security of a lock, as it keeps the door shut and offers additional resistance to force or kicks applied to the door. If a door is fitted with an electronic strike, it will be opened by using keys and the control unit that regulates the electrical impulses.
In the past, putting in an electronic strike required cutting a portion of a doorjamb to release the latchbolt of a cylindrical lock from the pocket that is inside the strike. This modification is not just ugly however, it also exposes the latchbolt mechanism and keeper to unauthorized users.
Recently, a number of electric strike makers have come up with a new type of electric strike, dubbed the "No Cut" strike that doesn't need cutouts in the doorjamb to function. upvc door locks replacement camberley Repair My Windows And Doors use a unique design to allow the keeper and latchbolt to slide into the strike pocket without damaging the faceplate of the doorjamb.
The strike is fitted with an internal ramp that lifts the latchbolt and keeper when it receives a signal from an individual reader. The latchbolt and keeper are lifted higher on the ramp thanks to the retract. When the door is shut, the deadbolt stays at a lower position and the latchbolt retracts into the keeper.
Installing an electronic strike is a straightforward procedure, especially if you're replacing an existing strike. If you're upgrading an access control system to an electric strike, it is important to ensure that your new system is compatible. Also, you must ensure that the strike is wired to your access control system and is designed to operate in a fail-safe manner.
One way to safeguard against access by unauthorized persons is to upgrade the strike on your doors to a heavy-duty strike plate. These plates use up to six screws of three inches instead of two screws of three-fourths of an inch. These screws are longer and make breaking the frame to reach the piece that turns the thumb on a single cylinder deadbolt more difficult.
