The various types of locks based on their purpose and an overview of their characteristics and functions is defined below in detail.

1. Internal Door Locks

Internal door locks provide security for interior doors such as bedrooms, bathrooms, and closets. They are usually knob locksets or lever handle locksets and may come in various finishes and security levels.

Types of Internal Door Locks

Knob Locks, Lever Handle Locks, Barrel Bolt, Deadbolt locks, Disc tumbler locks, Lever Handle Lock, Sliding Door Locks, and Latch, are classified as internal door locks, as they are commonly used to secure interior doors within a building or home.

  • Knob Locks

Knob locks are among the type of locks that are part of interior doors. They consist of a knob on one side of the door that turns to lock or unlock the door, and a keyhole on the other side for use with a physical key.

As an internal lock, knob locks offer a relatively low level of security and are not recommended for use on external doors. However, they are a cost-effective and easy-to-install type of locks for securing bedrooms, bathrooms, and closets within a home or office.

Pros of Knob Locks
  1. One of the main advantages of knob locks is their simplicity. Their maintenance requirements are minimal and are easy to operate.
  2. Knob Locks are available in a variety of finishes and styles to match the décor of your home or office.
Cons of Knob Locks
  1. Knob locks are susceptible to picking and bumping, which can compromise their security
  2. Knob Locks can be easily forced open with a wrench or other tools, making them a less secure option than other types of locks.
How to Pick Knob Locks

Following are the steps to pick a doorknob lock:

  1. Insert a tension wrench into the keyhole of the lock.
  2. Turn the tension wrench to find out which is the right direction for it to go.
  3. Now above the tension wrench, you are supposed to insert a pick.
  4. Use the pick to feel for the pins in the lock.
  5. Use gentle but steady pressure to lift each pin until it clicks into place.
  6. Move on to the next pin and repeat until all pins have been lifted.
  7. Turn the tension wrench to open the door.
  8. Remove the wrench and pick from the lock.

Knob locks are a popular and affordable option for internal doors but they are not suitable for high-security applications.

  • Lever Handle Locks

Lever handle locks are a type of lock often used for interior doors, and are commonly found in commercial or office settings. They consist of a handle that is pushed down to open the door, along with a keyhole that can be used to lock and unlock the door.

Cons of Lever Handle Locks
  • Lever Handle Locks can be more expensive than other types of locks.
  • Their handle can be easily grabbed with a tool or credit card to gain access without a key.
  • They are not as secure as deadbolts, which are often used in combination with lever handle locks.
How to Pick Lever Handle Locks
  1. Place a tension wrench into the keyhole’s bottom and then later exert force in a way that makes the key spin, in its direction.
  2. Feel for the pins with a pick inserted above the wrench.
  3. Apply upward pressure on each pin with the pick until it sets into place.
  4. Once all of the pins are in place, crank the tension wrench in the same way that the key would turn to unlock the door.
  5. Remove the wrench and pick from the lock.

Overall, lever handle locks are a convenient and stylish option for interior doors, but may not provide the highest level of security compared to other types of locks.

  • Barrel Bolt

Barrel bolts are a type of lock that is often used as a secondary locking mechanism on interior doors. They consist of a cylindrical barrel that slides into a bracket attached to the door frame.

  2. Now you have to put inside the pick above the wrench so that you can feel the pins.
  3. Apply upward pressure on each pin with the pick until it sets into place.
  4. Once all pins are set, turn the tension wrench in the direction the barrel would turn to unlock the door.
  5. Remove the wrench and pick from the lock.

Barrel bolts are a simple and inexpensive option for providing an additional layer of security on interior doors, but should not be relied on as the sole locking mechanism.

It is important to consider the specific needs of the situation when selecting a type of lock and to use barrel bolts in conjunction with other types of locks for maximum security.

  • Warded locks are relatively simple and inexpensive, making them a popular choice for low-security applications such as cabinets, lockers, and padlocks.
  • They are easy to install and maintain and do not require complex mechanisms or electronics to operate.
  • One of the advantages of warded locks is that they can be difficult to pick without the correct key.
  • The wards inside the lock prevent most lock picking tools from reaching the pins, making it harder for an intruder to open the lock. However, skilled lock pickers can use specialized tools such as skeleton keys or warded lock picks to bypass the wards and open the lock.
  • These locks do not require a lot of maintenance.
Cons of Warded Locks
  • Warded locks have limited key variation. Since the key has to navigate around the wards, there are only a few possible combinations for the key’s shape. This makes it easier to duplicate keys, and can also make it easier for someone to find a key that will fit the lock without having the original key.
How to Pick Warded Locks

How to pick a warded lock is discussed below:

  1. Use tension wrench to apply pressure in the direction of key rotation.
  2. Insert the pick into the keyhole and feel for the warding.

  2. Cracking: This method involves listening or feeling for the click or movement of the lock’s internal mechanism as you turn the dial, which can give you clues about the correct combination. Another method is to use a decoding tool, which can help you figure out the combination by feeling for the location of the internal components.
  3. Manipulation: This method involves carefully manipulating the lock’s internal components to align them and determine the correct combination. This requires a specialized tool and skill, but it is the most precise and least damaging method.
