How to Replace Door Locks
The first protection is your door lock. It will stop unauthorized access into your home. The 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 assist you select the appropriate lock.
Deadbolt
If you want to ensure your door is secure against intruders, it's a good idea to install a deadbolt. The bolt extends into the strike plate on the door frame when it's locked, making it much more difficult for burglars to gain entry into the door. A single-cylinder deadbolt can be activated using a key on the exterior, and the thumb-turn mechanism situated inside. Deadbolts can only function when it is properly installed.
It is first necessary to find out if the door has an existing hole for a deadbolt or if you'll need to drill it. Using the template that comes with the lock installation kit mark the spot of the deadbolt's hole on the door's surface. Utilize your tape measure to determine the height of the deadbolt. Mark this measurement on the door's edge. Use speedsquares to draw a straightline across the mark that you made for the bolt hole.
Next, use a power drill to bore out this hole until it extends to the other side of the door. This could take a bit of time. Sand the hole and the edge of the door to smooth it. At this moment, it's a good idea to paint or stain your door.
Once the door is ready take off any screws that are visible on the existing deadbolt. This will reveal both the front and rear assembly of the deadbolt as well as its bolt inside. Then, loosen the bolt and replace it with a new bolt that matches the door hardware. The bolt is usually connected to a setplate which you'll have to remove. After that then you need to chisel out the area for the strike plate that is on the door frame.
If your strike plate is not in alignment, it could be because the previous installer didn't mortise it properly or that an installation of a weatherstripping altered the strike's location. To fix this problem you'll need to remortise both the strike plate as well as the deadbolt. Close and lock the deadbolt once you have completed this step. Make sure the bolt extends into the strike plate then test the key to ensure it opens and closes easily.
Knob
It can make your home or business less secure if the door knob is worn. It can make opening or closing the door more difficult, so it's a good idea for you to replace the knob. Replacing knobs is an easy DIY task that should not take more than 30 minutes to complete. Use pliers or a screwdriver to remove any old knobs or handles. Be cautious not to damage other components of the door.
Before you begin you'll need to spray WD-40 or some other dry lubricant on the mechanism of the knob on your door. This will allow the lock to move smoothly when you turn it. It is essential to choose an excellent knob and handle that match your doors currently in order to ensure proper operation. If there's no match then you'll have to purchase an additional doorknob and latch plate.
To begin the replacement process, look at the knob or handle to determine what screws are holding 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 plate with hidden screws and pop it off.
After removing the old knob examine it for evidence of damage or rust. If the knob has any scratches or marks, you'll have clean it. Otherwise, it shouldn't require any major work.
It's time to install the new knob. Begin by examining the two new knobs to ensure you're selecting the correct one for your door. You'll need to pick 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 and then put it in the latch.
Test the spring by pressing down on it repeatedly. The latch should spring back up each time. Next, install the other new knob and connect it to the rod mechanism of the first knob. Thread the long screws of the interior doorknob into the holes for cylinders on the exterior knob and fix it in the knob's position.
Latch
A latch is a metallic piece that extends into the door jamb to secure it shut. It is operated with a knob or handle on the inside of the door or by a thumb turn on the exterior side of the door. A latch can be secured with a deadbolt to keep intruders from breaking in through the glass. It also protects against the accidental or deliberate closing of the door by children or pets. A latch can be set using a single cylinder deadbolt or double cylinder deadbolts based on the level of security you prefer.
Installing a latch follows the same steps like installing a deadbolt but there are a few differences. To ensure that the new lock is compatible first, determine the setback of the doorjamb with the tape measure. The setback is measured from the edge of doorjamb all the way to the center of hole for the latch plate. The standard setback is 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.
Next, make a hole for a latch plate in the edge of the doorjamb. Utilize a chisel to smooth out the mortise for the latch, making sure it's deep enough for the faceplate of the new latch to be flush with the doorjamb. Put the strike plate into place to make sure it is positioned correctly.
If the strike is too high, you could kick the door in or apply pressure with an iron tire or crowbar. This can also cause the doorjamb to break. To correct this issue, the strike can be lowered by drilling another hole through the doorjamb, and then cutting out the core of the old hole.
Installing the new strike plate is the last step. This can be accomplished by screwing the new plate into the existing screw holes. Then you can use wood putty to fill in the holes from the previous screws and the bolt hole that will not be used. Once the putty has dried, sand it to an even finish.
Strike
The metal piece that engages the deadbolt and latch when the door is shut is an electric strike. It is a vital part of the lock's overall security, as it prevents the door from opening, and also provides an additional barrier to force or kicking. If a door is equipped with an electric strike, it will only be opened with keys or the control unit that governs the electrical impulses.
In the past, installing an electronic strike was as simple as cutting a portion of a doorjamb in order to remove the latchbolt on a cylindrical lock from the pocket inside the strike. This modification is not just unattractive however, it also exposes the mechanism for the latchbolt and keeper to unauthorized users.
Recently, a number of electric strike manufacturers have created a brand new electric strike called the "No Cut" strike that doesn't require an opening in the doorjamb to operate. The strikes use a unique design that allows the keeper and latchbolt to slide into the strike pocket without marring the doorjamb faceplate.
The strike is equipped with an internal ramp that lifts the latchbolt and keeper whenever it receives an electrical signal from a reader or controller. The latchbolt and keeper are pushed higher on the ramp thanks to the retraction. When the door is shut, the deadbolt is retracted and the latchbolt is retracted into the keeper.
Installing an electronic strike is a straightforward procedure, particularly when you're replacing an older strike. If you are upgrading an existing access control system to an electric strike, you must make sure that the new system is compatible. Also, you must make sure that the strike is wired to your access control system and is configured for fail-safe operation.
One way to safeguard against unauthorized access is to upgrade the strike on your doors to a high-quality strike plate. These plates can be fitted with up to six screws of three inches instead of the standard two screws of three-fourths inches. These longer screws make breaking the frame to reach the piece that turns the thumb on a single deadbolt cylinder more difficult.
