When it comes to securing your home, your doors are one of the first lines of defence. While most people focus on their main entry door, patio doors and other sliding doors also need to be properly secured. Unlike a hinged door that swings on a fixed hinge, a sliding door slides along a track, and the locking mechanism is different. That’s why, when it comes to sliding doors, you’ll need a special type of lock set.

There are a variety of sliding door lock sets on the market, and it’s important to choose one that is both the right fit for your door and offers the level of security you need.

In this blog post, we’ll discuss the different types of sliding door lock sets available and how to choose the right one for your home. We’ll also provide some tips on understanding the security level of different lock sets.

Types of Sliding Door Lock Sets

There are two main types of sliding door lock sets:

  • Recessed Lock Sets: These lock sets are installed inside the door frame, out of sight. They are typically more aesthetically pleasing, but they can also be more expensive and more difficult to install.
  • Surface-Mounted Lock Sets: These lock sets are mounted on the surface of the door frame. They are typically less expensive and easier to install than recessed lock sets, but they may not be as aesthetically pleasing.

Choosing the Right Sliding Door Lock Set

When choosing a sliding door lock set, there are a few things to consider:

  • The size and thickness of your door: Make sure the lock set you choose is the right size for your door. You’ll also need to make sure that the lock set will fit the thickness of your door.
  • The material of your door: Some lock sets are designed for use with specific door materials, such as wood or aluminium. Make sure the lock set you choose is compatible with the material of your door.
  • The level of security you need: Sliding door lock sets come in a variety of security levels. If you’re looking for a high-security lock set, you’ll want to choose one that is made from durable materials and has a pick-resistant mechanism.
  • Your budget: Sliding door lock sets range in price from around $50 to $200 or more. Decide how much you’re willing to spend on a lock set before you start shopping.

Understanding the Security Level of Sliding Door Lock Sets

Sliding door lock sets are typically rated according to their security level. Some common security ratings include:

  • Grade 1: These are the most secure lock sets and are resistant to the most common break-in techniques.
  • Grade 2: These lock sets are less secure than Grade 1 lock sets, but they are still a good option for most homes.
  • Grade 3: These lock sets are the least secure and are only recommended for low-security applications.

Tips for Installing a Sliding Door Lock Set

If you’re comfortable doing so, you can install a sliding door lock set yourself. However, if you’re not comfortable with DIY projects, it’s always best to hire a professional locksmith.

Here are a few tips for installing a sliding door lock set:

  • Read the instructions carefully: Before you start installing your lock set, be sure to read the instructions carefully. The instructions will vary depending on the specific lock set you purchase.
  • Gather the necessary tools: You’ll need a few basic tools to install a sliding door lock set, such as a drill, a screwdriver, hole saw, spade bits, drill bits and square.
  • Take your time: Don’t rush the installation process. Take your time and make sure that the lock set is installed correctly.


By following these tips, you can choose the right sliding door lock set for your home and ensure that your home is properly secured.  If you’re ever unsure about what type of lock set you need or if you need help with installation, be sure to contact a qualified locksmith.
