Deadbolt

If you want to ensure your replacement patio door lock is secure against criminals, it's a great idea to install a deadbolt. The bolt extends into the strike plate on the doorframe when it is locked, making it much more difficult for burglars to gain entry through the door. A single cylinder deadbolt can be activated by a key on the exterior side and a thumb turn device on the inside. A deadbolt is only effective when it's properly installed however.

First, you will need to find out if the door has a hole for deadbolts or requires drilling. Using the template that comes with the lock installation kit, mark the spot of the deadbolt's hole on the door's surface. Use your tape measure to determine the height of the deadbolt. Mark this measurement on the door's edge. Use the speedsquare to draw a straight line across the mark you made for the bolt hole.

Then, use a power drill to drill this area until the hole extends to the other side of the door. This may take some time. Sand the hole and the edge of the door to make it smooth. It's also an excellent idea to paint or stain the door at this point.

Remove any screws that are visible from the deadbolt. This will reveal both the front and rear assemblies of the deadbolt, as well as its internal bolt. Then, remove the bolt and replace it with a new bolt that matches the door hardware. The bolt is typically connected to a setplate that you need to unscrew. Then, you'll need to chisel the area on the door frame to accommodate the strike plate.

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 it is necessary to remortise the strike plate as well as the deadbolt. Once you have completed this check the deadbolt by closing it and locking it. Be sure the bolt is extending into the strike plate, and then test the key to ensure it is able to open and close easily.

Spray WD-40, or a different dry lubricant, on the mechanism of your door knob before you begin. This will let the new lock to slide smoothly when you turn it. To ensure that it operates properly it is essential to select a knob and handle that match your existing doors. If there's no match, you'll need to buy an additional doorknob and latch plate.

Before you begin replacing the knob, take a look at the knob that was previously used to see what screws are keeping 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 that is hidden.

After taking the knob off, inspect it for evidence of damage or rust. You'll need to clean it off if there are any marks or dents however you don'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 to make sure that you are choosing the correct one for your door. You'll need to choose one with an extending rod that is designed to lock with the rod mechanism on the second knob. After you've placed the new knob over the hole in the door carefully slide it into the latch.

Test the spring by pressing down on it repeatedly. The latch should then spring back up every time. Install the second knob, and lock 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 its place.

Latch

A latch is a piece metal that extends into the door jamb to keep it shut. 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. A latch can be secured with a deadbolt to keep thieves from breaking through the glass. It can also guard against the accidental or deliberate closing by animals or children. You can install a latch with either a single-cylinder or double glazed door lock replacement-cylinder deadbolt, depending on the level you prefer for security.

Installing a deadbolt is the same as installing a latch however, there are some distinctions. First, you must measure the setback of the doorjamb with a tape measure to make sure the new lock will fit. The setback is the distance from the edge of the doorjamb, to the center of the hole for the faceplate of the latch. Setbacks for standard latches are 2 3/8 to 2. 3/4 inches. If your setback is higher it is possible to purchase a latch that is longer from a hardware or locksmith store.

Then, you'll need to make a hole for the latch plate at the edge of the doorjamb. Use a chisel and chisel the latch mortise. Make sure the hole's depth is enough to allow the faceplate to be in line with the doorjamb. Tape the strikeplate in place to ensure it is positioned properly.

If the strike is placed too high, the door can be pushed in or pressure put on it with a crowbar or tire iron. This can cause the doorjamb to break. To correct this, the strike could be reduced by drilling a second hole in the doorjamb and chiseling out the center of the hole that was previously drilled.

The final step is to mount the new strike plate, which can be accomplished by screwing it over the existing screw holes. Then you can use wood putty to fill in the screw holes that were previously used and the bolt hole that is not used. Once the putty has dried, sand it to a smooth finish.

Strike

The piece of metal that connects the deadbolt and latch when the door is closed is an electric strike. It is a crucial component of the security of a lock, because it seals the door and also provides additional resistance to force or kicks applied to the door. If a door is equipped with an electric strike, it can only be opened with an entry key or the control unit that controls its electrical impulses.

In the past, putting in an electronic strike required cutting a piece of a doorjamb, which would release the latchbolt of a cylindrical lock from the pocket inside the strike. This change can be an inconvenience in regards to the aesthetics of an opening, and it also exposes the mechanism of the latchbolt and keeper to unintentional users.

Recently, a variety of electric strike manufacturers have created a "No Cut" kind of strike that does not require a cutout in order to operate. They use a specific design that allows the latchbolt and keeper to slide into the pocket without damaging the doorjamb's faceplate.

The strike has an internal ramp that lifts the latchbolt and keeper whenever it receives an electrical signal from a reader or controller. The retraction of the keeper and latchbolt pushes them up higher on the ramp, thereby locking the door. When the door is closed the deadbolt remains retracted, and the latchbolt retracts into the keeper.

Installing an electric strike can be an easy task, especially in the case of replacing the strike on a previous door. 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 type of lock you have installed. You will also need to ensure 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 to heavy duty strike plates to block the entry of unauthorized persons. The plates utilize four to six screws of three inches instead of the two, three-fourth inch screws commonly employed in regular strikes. These screws are longer and make breaking the frame to reach the thumb turn piece on a single cylinder deadbolt more difficult.
