To accurately determine the size of a new lock for your door, you must first determine its case depth (or backset). van security hook locks is the distance from the edge of the door to the center of the latch hole.
Tubular Latch
The tubular latch is the most well-known door latch. It's simple to install and an absolute favorite among DIY enthusiasts and joiners alike. It's also available in a wide variety of sizes, shapes, and levels to match any style of door handle.
A tubular latch is a rectangular steel casing fitted with a latch bolt and an encased latch follower that is spring-loaded (also known as a striker). When you open the doors, the latch retracts allowing you to lock and close the door. When you close the door the latch bolt then springs back to catch on the edge of the frame and hold the door shut.
You'll need to determine the height of the door's latch before you install it. Many people believe that a lock and handle should be set at a height of one millimetre above the floor. However, this isn't the case. When it comes to door knobs, the latch should be placed on the mid-rail, which is where the majority of the weight is carried when you open and close the door.
Note the position of the hole in the door and strike plate with a pencil once you have determined the location where the latch should go. Then, drill pilot holes to the screws that are used to attach the plate to the door. After you've drilled the pilot holes, use a countersink to make sure that the plate's backside will be in line with the door after it's been screwed into place.
Consider a double-sprung lock for those who require a more durable alternative to the standard tubular lock. hook locks has a separate spring for the tongue, which results in a smoother closing when you close and open the door. It also features a strong-action, spring-loaded spindle follower that ensures that levers and doorknobs are returned to their horizontal positions after each use.
After you've secured the latch to the door, you'll need to install a strike plate onto the frame. The strike plate is a piece of metal that is inserted into the gap left behind by the latch after it's closed. You should mark the area where you'd like to put the strike plate on the frame surrounding it. Cut with your knife a square for the plate, and then take it off.
Cylindrical Latch
Interior doors are often equipped with cylindrical locks. They can be used in offices and homes, and are very versatile in terms of their applications. They are similar to mortise locks, however, they are much easier and faster to install. They don't require a "mortise" or pocket be cut into the door's frame like mortise locks do. The hole or bore is cut into the frame of the door and they are installed into that. These locks come in different grades and are compatible with levers and knobs to open and shut the door.
The main difference between mortise and cylinder locks is that cylinder locks can only be opened with the right type of key. This is because they employ pins of different heights inside the cylinder, and springs to hold the pins in the right position. When the right key is used into the cylinder, the pins align with one another, and the cylinder is able to rotate. This allows the latch bolts to retract, allowing the door to be opened.
If the wrong key has been put in, the pins aren't aligned correctly and prevent the cylinder from moving. This is why it's important to select the correct key whenever you want to enter your home or business.
The cylinder is located within the door's body and is connected to the operating trim with an oval or half-round extension. There are also tiny notches carved out of the cylinder's side that match with key notches. They are designed to align when the proper key is put in. Once the cylinder moves it will also move the latch bolt in tandem.
A strike plate is a metal plate that catches the bolt of the lock that is projected. The strike plate is generally made of heavy steel and it is secured to the door frame with screws. It also has an opening for the latch bolt to fit into.
When replacing a cylindrical lock, ensure you make use of the right tools to remove the handle of the old lock or knob and latch bolt. Note the position of the new latch bolt and strike on the frame and door after removing the old hardware. Once the latch bolt and strike plate are in position, it's a good idea to test the operation of the lock by pressing against it with your fingers. If the strike plate or latch bolt is damaged or does not work properly, you should consider replacing the bolts and strike plates.
Key-Locked Latch
This type of lock is controlled with a key on the outside and a knob or lever on the inside. This type of lock is designed for doors that aren't susceptible to being tampered with, like in offices. This kind locks allows the lever on the outside to be locked or unlocked, while the interior knob/lever remains free to be used for immediate exit. The key is required only to pull the latchbolt back when the door is shut.
The pins in a key-lock are pointed and lined up on a line called the shear line. These pins align with the shearline when the right key is placed into the lock. The plug is then turned to open the latchbolt. If you've ever had a key that was perfectly fitted into a lock but still isn't able to open it could be due to one of the pins isn't aligned with the shear line.
Face plates can also be found on some locks. They can be decorative or provide strength and security to the locking mechanism. These plates are commonly found on mortice locks, rim locks and locks with reversed springs.
There is also a strike plate, which is usually attached to the jamb and door frame and is fitted with a hole to guide the bolt from the cylinder to the lock. It is usually utilized in conjunction with deadbolts for added security.
Finally, there is the cylinder, which is a series of pins that align with the key's point to keep it from turning. A high-quality cylinder is extremely difficult to break into if you don't have the right tools and knowledge of how to pick it. To lock a front door, turn the key in the same direction that the door opens. For example, if the door opens right-handedly the key needs to be turned clockwise to lock it. To unlock the door, the key needs to be turned counterclockwise. This is different from other locks which require you to turn the key in the opposite direction of the direction the door opens, like for instance a Chubb lock.
Keyless Latch

The locks can be operated using the smartphone app or access code and some models include a hidden camera for additional security.

Several companies are developing smart lock technology that replaces traditional locks with keys, and adds security features. They can be locked with the use of a fingerprint, code, or facial recognition, and are typically more durable than traditional locks. Some smart locks have the ability to detect tampering, and detect if a door has been opened with an unauthorised key or force.
One company, known as Latch has created an elegant, high-tech lock that works like other smart locks. Its primary market is real estate firms who manage apartments. The tenants can open the lock using a passcode, key or mobile device. They are also able to let in dog walkers, cleaners or guests who are not from town by using temporary codes.

The Latch lock may not be available to consumers just yet however it may find a place in large apartments or condos. It's being tested in a few places and the company is planning to roll out more units this year. The cost is similar to a standard lock. The company also offers low costs for software and affordable pricing.
