Locks are one of the oldest and most reliable methods of keeping property secure. From the doors in our homes to safes, offices, and even vehicles, locks play a vital role in protecting what matters most. But not all locks are created equal. Different locks serve different purposes, and knowing the options available can help you choose the right type for your needs.
7 Different Types of Locks
In this article, we’ll explore the seven most common types of locks, their uses, and how locksmith services can assist you in selecting, installing, or repairing them.
1. Padlocks
Padlocks are perhaps the most recognizable lock type. They are portable and can be attached to gates, lockers, storage units, or chains. Padlocks come in two main varieties:
- Combination padlocks: Opened with a rotating dial and number sequence.
- Keyed padlocks: Opened with a physical key.
While convenient, padlocks are not always the most secure, as they can sometimes be cut or broken. A locksmith can help recommend high-security padlocks with features like hardened steel shackles or shrouded designs.
2. Deadbolts
Deadbolts are one of the most common locks used on residential front doors. Unlike spring-latch locks, they can’t be easily forced open with a knife or credit card. They come in three types:
- Single-cylinder deadbolts: Operated with a key from the outside and a thumb turn inside.
- Double-cylinder deadbolts: Require a key on both sides, offering more security but less convenience.
- Lockable thumb-turn deadbolts: A hybrid option providing both safety and flexibility.
Locksmiths often recommend deadbolts for exterior doors because they provide strong resistance against forced entry.
3. Knob Locks
Knob locks are commonly found on interior doors and sometimes on exterior ones. The lock mechanism is inside the knob itself. However, they are not very secure for main doors, as the knobs can be easily broken or bypassed.
A locksmith will often suggest using knob locks in combination with a deadbolt to strengthen front-door security.
4. Lever Handle Locks
Lever handle locks are designed for ease of use and are popular in commercial buildings, hospitals, and offices. Instead of turning a knob, you push down on a lever to open the door.
These locks are more accessible for people with disabilities or limited hand strength. Professional locksmiths often install lever handle locks to comply with accessibility standards in workplaces and public facilities.
5. Cam Locks
Cam locks are small and often used in filing cabinets, mailboxes, and storage units. They operate with a key that rotates a metal piece (the “cam”) to lock or unlock.
Although cam locks are compact, they provide decent security for specific uses. Locksmiths frequently help businesses replace or rekey cam locks when employees change or keys go missing.
6. Mortise Locks
Mortise locks are heavy-duty locks often found in older buildings and commercial settings. Installed inside a pocket or “mortise” in the door, these locks are extremely durable and can withstand a lot of wear and tear.
They usually come with both a latch and a deadbolt in one unit. Locksmiths value mortise locks for their strength and longevity, and they can repair or retrofit them to fit modern security standards.
7. Electronic or Smart Locks
The newest type of lock, electronic or smart locks, has grown in popularity for both residential and commercial use. They can be operated with keypads, keycards, smartphones, or even biometrics like fingerprints. Some connect to Wi-Fi or Bluetooth, allowing remote access and monitoring.
Locksmiths play a key role in installing, programming, and troubleshooting smart locks. They can also advise on which models are most reliable and secure for your situation.
