How to Replace Door Locks
The first line of defense is your door lock. It will stop unauthorized access into your home. Signs of wear and tear, and also instances like moving into a new residence or burglaries, could trigger the need to replace your lock.
To begin, determine the size of your cylinder by measuring the distance between the adjustment screw and the center of the cylinder knob. This measurement will allow you to purchase the appropriate lock.
Deadbolt
Installing a deadbolt is a great way to secure your door against intruders. When the bolt is extended into the strike plate of the doorframe it makes it much more difficult for an intruder to break through the door. A single cylinder deadbolt is activated by an exterior key on the side and a thumb turn device on the inside. A deadbolt will only work if it's installed correctly however.
It is first necessary to determine if the door has a hole that is suitable for a deadbolt or if you have to drill it. Utilizing the template included with the lock installation kit mark the location of the deadbolt hole on the door's surface. Use your tape measure to determine the height of the deadbolt. Mark this height on the door edge and use speedsquares to draw a straight line across the mark you made to mark the bolt hole.
Then, using the power drill, drill through the hole until it is on the opposite side of the door. It may take a while. Sand the hole and edge of the door to make it smooth. It's also a good idea to stain or paint the door at this point.
Remove any screws that are visible from the deadbolt. This will reveal the front and rear assembly of the deadbolt and its internal bolt. Then, unscrew double glazed door lock replacement rayleigh repairmywindowsanddoors.co.uk and replace it with a new one that is compatible with the door hardware. The bolt is usually connected to a setplate that you have to remove. After that, you'll have to chisel the door frame for the strike plate.
If your strike plate isn't aligned properly It's likely that the previous installer didn't mortise it correctly or a weatherstripping popped up and altered the strike position. To correct this issue, you will need to remortise both the strike plate and the deadbolt. Close and lock the deadbolt once you've completed this step. Be sure the bolt extends into the strike plate and then test the key to make sure it closes and opens smoothly.
Knob
When a door knob is worn out it could make your home or business less secure. It can make it more difficult to open or close the door, which is why it's a good idea to replace it. Replacing the knob is an simple DIY project that shouldn't take more than 30 minutes to complete. Make use of pliers or a screwdriver to remove any old knobs or handles. Be careful not to harm other parts of the door.
Before starting, you'll want to spray WD-40 or a different dry lubricant onto the mechanism of the door knob. This will allow the new lock slide smoothly when you turn it. It's important to use the best knob and handle that matches your current doors to ensure proper operation. If you don't have a matching knob you'll need to purchase a replacement doorknob and latch plate.
To begin the replacement process, first examine the old knob or handle to determine the screws that hold it in place. If there aren't any screws, you can make use of a screwdriver and wedge it between the cover plate and the hidden screws plate and then remove it.
After you've removed the knob that was previously used, look it over for indications of damage or rust. You'll need to clean it off if you notice any marks or dents however you don't need to do anything If the knob is in good working order.
Now it's time to install the new one. You must first study the two knobs in order to make sure that you've chosen the correct one for your door. You'll need to choose one with an extender rod that is interlocked with the rod mechanism of the other knob. After you've placed the new knob in the hole in the door and then carefully place it in the latch.
Thread the latch plate screws down and test the spring by pushing down on it several times. The latch should spring back up every time. Install the second knob and lock it to the rod mechanism of the first knob. Attach the other long screws from the knob's interior through the hole in the cylinder of the doorknob outside and lock it in place.
Latch
A latch is a metallic piece that extends into the doorjamb to secure it closed. It is operated by a knob or handle on the inside of the door or by a thumb turn on the exterior side of the door. The latch can be secured with deadbolts to stop thieves from breaking through the glass of the door. It also offers protection from the accidental or deliberate closing of the door by children or pets. A latch can be installed using a single cylinder deadbolt or double cylinder deadbolts based on the level of security you prefer.
Installing a latch requires the same steps as installing a deadbolt, however, there are a few distinctions. First, you must measure the setback of the doorjamb by using a tape measure to be sure that the new lock will fit. The setback is the distance from the edge of the doorjamb to the center of the hole to accommodate the faceplate for the latch. Setbacks for standard latches are 2 3/8 to 2. 3/4 inches. If your setback is higher, you may need to purchase an extra-long latch from a hardware or locksmith store.
The next step is to drill an edge bore hole into the doorjamb for the latch plate. Utilize a chisel to smooth out the mortise of the latch making sure it's large enough for the faceplate of the new latch to sit flush with the doorjamb. Tape the strikeplate to the doorjamb to ensure it is positioned properly.
If the strike is positioned too high, the door could be pushed in or pressure put on it using a crowbar or tire iron. This can cause the doorjamb to break. To correct this, the strike could be lowered by drilling a new hole through the doorjamb, and then chiseling out the center of the previous hole.
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 old bolt holes or screw holes that won't be used. Once the putty has dried then sand it to an even finish.
Strike
An electric strike is the metal piece that holds the deadbolt and latch engage when the door is closed. It is an essential part of the lock's overall security because it stops the door from opening and provides an additional barrier to force or kick. If a door has been equipped with an electric strike, it can only be opened using a key or the control unit that controls its electrical impulses.
Traditionally the installation of an electric strike meant cutting a section of the doorjamb in order to remotely remove the latchbolt of a cylindrical lock from the pocket within the strike. This change can be an inconvenience in regards to the appearance of an opening as well as exposing the keeper mechanism and latchbolt to unauthorized users.
Recently, a number of electric strike manufacturers have developed an innovative type of electric strike dubbed the "No Cut" strike that doesn't need a cutout 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 has an internal ramp that lifts the latchbolt and keeper when it receives the signal of an individual reader. The latchbolt and keeper are pushed up the ramp by the retract. When the door is closed the deadbolt remains in place and the latchbolt retracts into the keeper.
Installing an electronic strike is a simple procedure, especially when you're replacing an older strike. However, if you're upgrading to an electric strike in an access control system, you will have to ensure that your new system is compatible with the kind of lock you've chosen to install. It is also necessary to make sure that the strike is properly wired to your access control system and is designed to operate in a fail-safe manner.
Upgrade your strike plates with heavy duty strike plates to block unauthorised entry. These plates use up to six screws of three inches instead of the usual two screws of three-fourths inch. These screws are longer, making it harder for anyone to break the frame and reach inside to turn the thumb turn part of a single cylinder deadbolt.
