What are the different door lock types?

In the world of security, the importance of door locks cannot be overstated. They are the first line of defense in protecting your home, office, or vehicle. With a myriad of lock types available, understanding each one is crucial for choosing the right security level for your needs.

Different Types of Door Locks

1. Padlocks

Padlocks are freestanding, portable locks. They come in various sizes and security levels, from basic luggage locks to high-security padlocks.

2. Deadbolts

Deadbolts offer a higher security level for residential doors. They operate separately from the doorknob and are moved by turning a key or a thumb turn.

3. Knob Locks

Commonly used in residential properties, knob locks are built into the doorknob. They are convenient but not as secure as deadbolts.

4. Lever Handle Locks

These are frequently found in commercial settings. They have a large push-down style handle and are easier to open, making them ADA compliant.

5. Cam Locks

Cam locks are used in cabinets and mailboxes. They have a rotating bar (cam) that locks or unlocks the device.

6. Rim/Mortise Locks

Used in commercial spaces and apartments, these locks are either rim cylinders or mortise cylinders, offering good security.

7. Electronic Locks

Electronic locks use a keypad, fingerprint, or smart technology. They are increasingly popular in modern homes and offices.

8. Smart Locks

Smart locks connect to your home Wi-Fi or Bluetooth. They can be controlled remotely and often include features like voice commands and tracking who enters your home.

9. Chain Locks

Chain locks are an additional security measure used alongside other lock types, especially on doors without a peephole.

10. Jimmy Proof Deadbolts

Often found in apartments and older homes, these locks are surface mounted and offer a decent level of security against jimmying.
