Introduction

Your patio doors are one of the most beautiful features of your home—but they’re also a potential target if not properly secured. Whether you’ve chosen sliding doors, bifold doors, or French doors, understanding your patio door lock options is essential for both security and peace of mind.

In this guide, we’ll walk you through what locking systems typically come with patio doors, how secure they are, and what extras you can add to ensure your home stays safe without compromising on style.

What Counts as a Patio Door?

When we talk about “patio doors,” we’re not referring to just one product type. This term generally includes three main options:

French Doors

Double doors that swing open from the centre—great for classic aesthetics and smaller openings.

Sliding Doors

One or more panels glide open sideways along a track. Perfect for wide openings and uninterrupted views.

Bifold Doors

Multiple hinged panels that fold and slide neatly to the side (also referred to as folding doors)—ideal for creating seamless indoor-outdoor flow.

At GFD Homes, we offer a great range of patio doors from trusted UK brands like Smart, Korniche, and Deceuninck. All come with high-spec locking systems and upgrade options.

What Locks Come with Patio Doors?

Most modern patio doors come fitted with multi-point locking systems as standard. These lock into multiple places along the frame when closed, offering better resistance to forced entry than older single-point locks.

  • Internal key-lockable handles

Standard locks on today’s patio doors are very secure—but if you’re especially security-conscious or live in a high-risk area, consider the following upgrades (if they’re available to purchase):

  • Internal locking shoot bolts for French or bifold doors

Yes— all of our patio doors come with built-in multi-point locks and a 3-star security cylinder as standard.

Can I change the lock on my patio door?

Not at all—both offer strong locking systems when sourced from quality manufacturers and properly installed.
