Different types of locks and when to choose the same

Deadbolt locks

Deadbolt locks are one of the most common and secure locks used in residential properties. They are typically installed on exterior doors and operate with a key from the outside and a thumb turn on the inside. Deadbolts come in single-cylinder and double-cylinder versions. Single-cylinder deadbolts are more convenient, allowing you to unlock the door from the inside without a key. Double-cylinder deadbolts, which require a key on both sides, offer extra security but can be a safety concern in emergencies.

When to choose: A deadbolt is an excellent choice for reliable locks for your main entry doors. Opt for a double-cylinder deadbolt if you have windows near your door that could be broken to reach the thumb turn.

Knob locks

Knob locks are frequently found on interior doors in homes and offer basic security. The locking mechanism is located within the knob itself, making it more vulnerable to forced entry compared to deadbolts. While knob locks are easy to install and use, they are not recommended as the sole security measure for exterior doors.

When to choose: Use knob locks for interior doors, such as bedrooms, bathrooms, or closets. For exterior doors, pair them with a deadbolt for added security.

Lever handle locks

Lever handle locks are similar to knob locks but use a lever instead of a knob to operate the latch. They are often used in commercial settings or interior doors where ease of access is important, especially for individuals with disabilities. Lever handle locks provide a stylish alternative to knob locks and are available in various designs.

When to choose: Lever handle locks are ideal for interior doors in homes and offices, especially in areas where accessibility is a concern.

Cam locks

Cam locks are commonly used in furniture, mailboxes, cabinets, and other low-security applications. They consist of a metal plate (the cam) that rotates with the key to lock or unlock the mechanism. While unsuitable for high-security needs, cam locks are versatile and easy to install.

When to choose: Cam locks are perfect for securing cabinets, drawers, or mailboxes. They are also perfect for applications where convenience and low security are the primary concerns.

Smart locks

Smart locks represent the latest lock technology, allowing you to lock and unlock your doors using a smartphone, key fob, or voice commands. They often integrate with home automation systems and provide features like remote access, temporary access codes, and activity logs. At the same time, convenient and feature-rich, smart locks require a stable power source and can be more expensive than traditional locks.

When to choose: Smart locks are ideal for tech-savvy homeowners who want enhanced control over their home security. They are especially useful if you frequently need to grant access to guests, service providers, or family members.
