How to Replace Door Locks
Door locks are your first protection against unauthorised entry into your home. www.repairmywindowsanddoors.co.uk may require replacement because of signs of wear and tear or other circumstances such as moving into a new home or a burglary.
You can determine the size of your cylinder by measuring the distance from the center of the knoblock cylinder to the adjustment screw. This measurement will enable you to purchase the correct-sized lock.
Deadbolt
Installing a deadbolt can be a ideal way to secure your door from intruders. The bolt extends into the strike plate on the door frame when it's locked, making it more difficult for burglars to break in through the door. A single cylinder deadbolt is activated by keys on the exterior side and a thumb turn piece on the inside. A deadbolt will only work when it's properly installed however.
You will first need to determine if the door has an existing hole for a deadbolt or if you'll need to bore it 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 your tape measure to determine the height of the deadbolt. Then, mark this high point on the outside of the door. Use the speed square to draw a straight line across the mark you made for the bolt hole.
Then, use a drill to bore this spot until the hole extends to the other side of the door. This may take a while. Then, sand down the hole and the edges of the door so that it is smooth. At this moment, it's a good idea also to stain or paint your door.
Remove any visible screws from the deadbolt. This will reveal the front and rear assembly of the deadbolt, as well as its bolt inside. Then, remove the bolt and replace it with a new one that is compatible with the door hardware. It is necessary to remove the bolt from a setplate. After that then you need to cut out the space for the strike plate on the door frame.
If your strike plate is not in alignment, it could be because the previous installer didn't mortise it correctly or a weatherstripping changed the strike's position. You'll need to re-mortise the strikeplate and possibly even the deadbolt itself to fix the issue. Close and lock the deadbolt after you've completed this process. Test the deadbolt by closing and locking it once the bolt has been extended into the strike plate.
Knob
It can make your home and business less secure if the door knob is damaged. It could make it more difficult to open or close the door, so it's an ideal idea to replace the knob. Replacing a knob is a relatively simple DIY project that shouldn't take less than 30 minutes to complete. Use a screwdriver or pliers to take off any knobs or handles. Be careful not to scratch 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 allow the new lock to slide smoothly when you turn it. It's essential to select a quality knob and handle that match your current doors to ensure that the lock is operating properly. If you don't have a doorknob that is compatible then you'll have to purchase a replacement.
To begin the replacement process, first look over the knob or handle to see the screws that hold it in place. If there are no screws then you can use the screwdriver to secure the cover plate between the screws plate that is hidden.
Once you've removed the knob, check it for any indications of damage or rust. If the knob shows any scratches or marks it's time clean it. Otherwise, it shouldn't require any major work.
Install the new knob. 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 that has an extending rod that is designed to lock with the second knob's rod mechanism. Once you've put the new knob into the hole and then put it in the latch.
Test the spring by pressing down on it repeatedly. The latch should spring up each time. Then, put in the new knob and connect it with the rod mechanism on the first knob. Thread in the other long screws from the interior knob through the cylinder hole on the exterior doorknob and secure it.
Latch
A latch is a piece of metal that extends into the door jamb to keep it shut. The latch is operated by a knob or handle on the inside of the door, or by a thumb-turn on the exterior. The latch can be secured with a deadbolt to keep intruders from breaking in through the glass of the door. It can also protect against accidental or intentional closing by children or animals. It is possible to install the latch using either a single-cylinder or double-cylinder deadbolt, depending on the level of security.
Installing a latch follows the same steps like installing a deadbolt however there are some differences. To make sure that the new lock will fit first, take a measurement of the setback on the doorjamb with a tape measure. The setback is measured from the edge of the doorjamb all the way to the center of hole for the latch plate. Setbacks for standard latches are 2 3/8 to 2. 3/4 inches. If you have a larger setback, you may have to purchase a longer latch from a hardware store or locksmith.
Next, make a hole for the latch plate at the doorjamb's edge. Use a chisel and chisel the latch mortise. Make sure the hole's depth is sufficient for the faceplate to be flush with the doorjamb. Tape the strikeplate to the doorjamb to ensure that it's positioned properly.
If the strike is positioned too high, the door could be kicked in or pressure put on it with a crowbar or tire iron. This can cause cracks to the doorjamb. This can be corrected by drilling a new hole into the doorjamb, and cutting the core from the previous one.
The last step is to mount the new strike plate which is done by screwing it in place over the screw holes that are already in place. Then apply wood putty to fill in the screw holes that were previously used and the bolt hole that will not be used. When the putty is dry, sand it smooth for an elegant finish.
Strike
An electric strike is the metal piece where the deadbolt and latch are engaged when the door is shut. It is a crucial component of the overall security of a lock because it seals the door and also provides additional resistance to kicking or force applied to the door. If a door is equipped with an electronic strike, it will be opened only by keys and the control unit that regulates the electrical impulses.
Traditionally the installation of an electric strike required cutting a section of the doorjamb to remotely remove the latchbolt of a cylindrical lock from the pocket within the strike. This change can be a drawback when it comes to the appearance of openings, and it also exposes the latchbolt and keeper mechanism to unauthorized users.
Recently, several electric strikes manufacturers have created a "No Cut" kind of strike that doesn't require a cutout to operate. The strikes have a unique design that allows the latchbolt and keeper to slide into the pocket without damaging the faceplate of the doorjamb.
The strike has an internal ramp that lifts the latchbolt and keeper when it receives an electrical signal from a controller or reader. The latchbolt and keeper are pushed higher up the ramp by the retract. When the door is shut, the deadbolt stays extended and the latchbolt is retracted into the keeper.
Installing an electric strike can be an easy process, particularly if you are replacing the strike on a previous door. If you are upgrading an existing access control system to an electric strike, you must ensure that the new system is compatible. It is also necessary to make sure that the strike is properly wired to your access control system and that it is configured for fail-safe operation.
Upgrade your strike plates to high duty strike plates to prevent unauthorized entry. These plates can be fitted with up to six screws of three inches instead of two screws of three-fourths of an inch. These screws are longer, making it more difficult for people to break the frame and then reach inside to turn the piece that turns the thumb of a single deadbolt cylinder.
