How to Replace Door Locks
Your first protection is your door lock. It will stop unauthorized access to your home. The locks may require replacement due to wear and tear or other circumstances like moving into a new residence or a burglary.
To begin, you must determine the size of your cylinder using the distance between the adjustment screw and the center of the knob lock cylinder. This measurement will allow you to purchase the appropriate lock.
Deadbolt
If you want to ensure your door is secure from burglars, it's a good idea to install a deadbolt. 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 with a key on the outside and a thumb-turn piece that is located inside. Deadbolts are only effective when it's properly installed however.
First, you must determine if the door has a hole that is suitable for a deadbolt or if you have to drill it. Mark the position of the hole for the deadbolt on the exterior of the door using the template included with the lock installation set. Utilize your tape measure to determine the height of the deadbolt. Then, mark the height on the edge of the door. Use a speed square to draw straight lines across the mark you made for the bolt hole.
Then by using an electric drill, bore through the hole until it is on the opposite side of the door. It could take a few minutes. Sand the hole and the door edge to make it smooth. At this point, it's a good idea also to stain or paint your door.
Remove any screws that are visible from the deadbolt. This will reveal the back and front assemblies of the deadbolt and also the bolt that is inside. Then, loosen the bolt and replace it with a brand new one that is compatible with your door hardware. You'll need to remove the bolt from the setplate. Then, you'll need to chisel the surface of the door frame to accommodate 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. It is necessary to re-mortise the strike plate and possibly even the deadbolt itself to correct this problem. Once this is completed, test the deadbolt by closing it and locking it. Be sure the bolt extends into the strike plate and then test the key to make sure it closes and opens smoothly.
Knob
It could make your home or business less secure if the door knob is damaged. It could make it more difficult to open or close the door, making it recommended to replace the knob. It shouldn't take you more than 30 minutes. You can use a screwdriver or pliers to take off the knob or handle that was previously used However, be careful not to harm any of the other components on the door.
Before starting, you'll want to spray WD-40 or another dry lubricant on the mechanism of the door knob. upvc door locking mechanism replacement will let the new lock slide smoothly as you turn it. To ensure that it operates properly, it's important to choose the knob and handle that match the doors you already have. If you don't already have a doorknob that is compatible and handle, you'll need to purchase a replacement.
Before you begin replacing the knob, look over the knob you replaced to determine which screws are keeping it in place. If there aren't screws then you can use the screwdriver to insert the cover plate into the hidden screws plate.
After you've removed your knob that was previously used, look it over for signs of damage or rust. You'll have to scrub it up if there are any marks or dents, but you shouldn't have to do anything major If the knob is in good shape.
Now is the time to put in the new one. You should first examine the two knobs to ensure that you've chosen the correct one for your door. You'll need to pick one with an extended rod that locks with the rod mechanism of the other knob. After you've inserted the new knob into the hole, slide it into the latch.
Test the spring by pressing it down repeatedly. The latch should then spring back up each time. Next, install the other new knob and interlock it with the rod mechanism of the first knob. Thread the long screws from the interior doorknob through the holes for the cylinder on the outside knob and lock it into place.
Latch
A latch is a metallic piece that extends out into the doorjamb to keep it closed. It is operated by a knob or handle on the inside of the door or a thumb turn on the exterior side of the door. Deadbolts can be used to secure a latch and prevent intrusions 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 set with one cylinder deadbolt or a double cylinder deadbolt, based on the level of security you prefer.
Installing a deadbolt is the same as installing a latch however there are some differences. To ensure that the new lock will work first, you must measure the setback on the doorjamb using a tape measure. The setback is measured from the edge of doorjamb up to the middle of the hole for the latch plate. A standard setback is 2 3/8 to 2 3/4 inches. If you have a higher setback, you may have to purchase a more substantial latch from a hardware shop or locksmith.
The next step is to drill an edge bore hole through the doorjamb to accommodate the latch plate. Use a chisel for chiseling out the mortise for the latch making sure it's large enough for the faceplate of the new latch to sit flush with the doorjamb. Tape the strike plate in the correct position to ensure it's in the right position.
If the strike is positioned too high, the door can be pushed into or pressure applied to it using a crowbar, or tire iron. This can cause the doorjamb to crack. This can be corrected by drilling a new hole in the doorjamb, then chiseling the core out of the old one.
Installing the new strike plate is the final step. This can be done by fixing the new plate to the existing screwholes. Then apply wood putty to fill in the screw holes that were previously used and the bolt hole that will not be used. After the putty has dried then sand it to a smooth finish for a professional finish.
Strike
An electric strike is a metal piece where the latch and deadbolt engage when the door is closed. It is a vital part of the lock's overall safety, as it prevents the door from opening, and also provides an additional barrier to force or kick. If a door has been equipped with an electric strike, it can be opened by keys or the control unit that governs its electrical impulses.
Traditionally the installation of an electric strike required cutting a section of the doorjamb to remotely remove a cylindrical lock's latchbolt from the pocket within the strike. This modification is not only unattractive however, it also exposes the mechanism of the latchbolt and the keeper to intruders.
Recently, several electric strikes manufacturers have developed a "No Cut" kind of strike that doesn't require a cutout to operate. They use a specific 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 raises the latchbolt and keeper when it receives an indication from an individual reader. The latchbolt and keeper are lifted higher up the ramp by the retraction. When the door is closed, the deadbolt remains retracted, and the latchbolt retracts into the keeper.
Installing an electric strike can be an easy process, particularly if you are replacing a strike on an existing door. If you are upgrading an access control system to an electric strike, you need to ensure that the new system is compatible. It is also necessary to make sure that the strike is connected to your access-control system and is set up to operate in a fail-safe way.
Upgrade your strike plates with heavy duty strike plates to stop unauthorized entry. The plates are made of up to six screws of three inches instead of the standard two screws of three-fourths inches. These screws are longer and make breaking the frame to reach the thumb turn piece on a single deadbolt cylinder more difficult.
