What you need to know before buying new locks

Locks are an essential component of home and business security. They are designed to protect your property, belongings, and loved ones from unwanted intruders.

But with the vast array of locks available in the market, choosing the right one can be an overwhelming task.

This comprehensive guide will help you understand the key factors to consider before buying new locks, from the locksmith’s perspective. We will discuss various types of locks, their features, and how to choose the best one for your needs.

Understanding the Basics of Locks

Components of a Lock

Before diving into the world of locks, it is essential to understand the basic components that make up a lock. These include:

  1. Cylinder: The cylinder is the part of the lock where the key is inserted. It contains the pins, springs, and tumblers that work together to grant or deny access.
  2. Bolt: The bolt is the metal piece that slides into the door frame when the lock is engaged, securing the door in place.
  3. Keyway: The keyway is the channel inside the cylinder that accommodates the key.
  4. Strike Plate: The strike plate is the metal piece attached to the door frame that the bolt slides into when the door is locked.

Types of Locks

There are several types of locks available in the market, each designed for specific purposes and levels of security. Some of the most common ones include:

  1. Padlocks: Padlocks are portable and versatile locks that can be used for various purposes. They come in different sizes, shapes, and security levels.
  2. Deadbolts: Deadbolts are one of the most secure types of locks used for residential and commercial doors. They are operated using a key or a thumb-turn from the inside.
  3. Knob Locks: Knob locks are commonly used for interior doors in homes and offices. They are less secure than deadbolts and are not recommended for external doors.
  4. Lever Handle Locks: Lever handle locks are designed for ease of use and are commonly found in commercial settings where accessibility is essential.
  5. Mortise Locks: Mortise locks are installed within a door, providing a high level of security. They are commonly used in commercial settings and older residential properties.
  6. Electronic Locks: Electronic locks use keypads, cards, or biometric data to grant access, providing added convenience and security.

Factors to Consider When Buying New Locks

Security Level

The primary purpose of a lock is to provide security. Therefore, it is essential to consider the level of security you require before choosing a lock.

Locks are generally graded on a scale of 1 to 3, with Grade 1 being the highest level of security and Grade 3 being the lowest. Deadbolts, mortise locks, and high-security padlocks typically offer the highest levels of security.

Purpose and Location

The purpose and location of the lock are crucial factors to consider when buying new locks. For instance, exterior doors require more robust and secure locks than interior doors. High-security locks are ideal for front and back doors, while knob locks and lever handle locks may be more suitable for interior doors.


Locks come in a wide range of prices, depending on the type, materials, and security features. It is essential to set a budget for your lock purchase, keeping in mind that high-quality locks may come at a higher price but offer better security and durability.

Lock Material

The material used in manufacturing a lock can impact its durability, security, and overall appearance. Common lock materials include brass, steel, and zinc alloy.

Brass locks are popular for their aesthetic appeal and resistance to corrosion, while steel locks offer superior strength and durability. Zinc alloy locks are a cost-effective option that provides a balance of strength and corrosion resistance.

Ease of Installation

Some locks are easier to install than others, which can be a significant factor to consider if you plan on installing the lock yourself. Deadbolts, padlocks, and knob locks are generally easier to install, while mortise locks and electronic locks may require professional installation due to their complexity.

Key Control

Key control refers to the ability to limit the duplication of keys for your lock. High-security locks often come with restricted keyways and patented key designs that make it difficult for unauthorized individuals to duplicate keys.

Consider the level of key control you require, especially for exterior doors and areas with sensitive information or valuable items.

Compatibility with Existing Hardware

Before purchasing a new lock, ensure that it is compatible with your existing door and hardware. Consider factors such as door thickness, backset measurements, and the size and shape of the lock’s components.
