4 Types Of Locks You Should Know

Creating a secure environment for your home, office, or rental properties is crucial in today’s world. The right locks can make a significant difference in your property’s safety and your peace of mind. As a property owner, understanding the various types of locks and their specific uses allows you to make informed decisions about the security measures you implement. In this guide, we’ll explore four essential types of locks you should know about.

Deadbolt Locks: The Foundation of Home Security

Deadbolt locks are synonymous with security. Their design includes a solid metal bolt that extends from the lock into the door jamb and frame, providing a high level of resistance to forced entry.

  • Single-cylinder deadbolts are operated with a key from the outside and a thumb turn from the inside. They are a popular choice for residential homes, providing a good balance between security and convenience.
  • Double-cylinder deadbolts require a key for operation from both the inside and outside. While they offer an added layer of security, they can pose a risk during emergencies by potentially blocking quick exits. It’s important to consider this aspect and local safety codes when installing double-cylinder deadbolts.

Deadbolts are recommended for all exterior doors, including front, back, and side entries, to deter break-ins effectively.

Keyless Entry Locks: Convenience Meets Technology

The rise of smart technology has made keyless entry locks a popular choice for modern homes and businesses. These locks eliminate the need for traditional keys, instead relying on electronic mechanisms to control access.

  • Keypad locks require a numeric code for entry, making it easy to change access codes without the need for physical key exchanges. This feature is particularly useful for rental properties or Airbnb accommodations.
  • Biometric locks use fingerprint recognition to allow entry, offering a high security level as fingerprints are unique to each individual.
  • Wireless locks can be controlled remotely via a smartphone or computer, providing the flexibility to manage access from anywhere. This is especially handy for managing multiple properties or granting temporary access to service providers.

Keyless entry systems are an excellent way to enhance security while offering the convenience of remote access management. They are also beneficial for tracking who comes and goes, adding an extra layer of security through monitoring.

Knob Locks: Basic but Essential

Knob locks are among the most common types of locks for interior doors. The lock mechanism is integrated into the doorknob itself.

While knob locks offer ease of use and installation, they are not the most secure option for exterior doors due to their vulnerability to forceful entry methods like hammering, wrenching, or prying. For this reason, knob locks should primarily be used for interior doors or paired with more secure locks, like deadbolts, on exterior doors.

Despite their limitations in security, knob locks play a crucial role in residential privacy and safety, especially for bedrooms and bathrooms, where privacy is a priority.

Lever Handle Locks: Accessibility and Functionality

Lever handle locks are often found in commercial settings but are also suitable for residential use, particularly for interior doors. The lever handle design is easier to operate than a traditional knob, making it an excellent choice for people with limited hand dexterity or disabilities.

Lever handle locks come in various configurations, such as passage, privacy, and entry/office functions, allowing for tailored security levels depending on the door’s location and purpose. While offering convenience and compliance with accessibility guidelines, it’s important to choose lever handle locks with robust security features for exterior doors.

Lock Selection for Landlords: Enhancing Tenant Security

For landlords, the safety and security of tenants should be a top priority. The right locks can make a significant difference in a rental property’s overall security. Here are some considerations for landlords when choosing locks:

  • Assess Tenant Needs: Different tenants have different security needs. For instance, tenants who work late might benefit from the added security of keyless entry systems, while families might prioritize ease of use and reliability.
  • Regular Maintenance: To ensure locks remain functional and secure, regular maintenance is crucial. This includes checking for signs of wear and tear, ensuring locks operate smoothly, and replacing batteries in electronic locks.


Choosing the right locks for your property is a critical step in safeguarding your assets, tenants, and peace of mind. By understanding the strengths and applications of different lock types, you can create a layered security approach that meets your specific needs. Whether you’re a homeowner looking to upgrade your security or a landlord responsible for the safety of your tenants, investing in quality locks and regular maintenance can provide lasting benefits and security for everyone involved.

Remember, the goal is not just to lock doors but to create a safe and secure environment where people can live and work with confidence. If you’re ready to enhance your property’s security, consider these lock options and take proactive steps today.
