This comprehensive guide will provide you with all the information you need to know about UPVC door locks to keep your house secure.

What are UPVC Door Locks?

Understanding UPVC

UPVC stands for Unplasticised Polyvinyl Chloride, a rigid and durable material widely used in the construction industry.

UPVC is known for its weather resistance, energy efficiency, and low maintenance requirements. Because of these qualities, it has become a popular choice for window and door frames.

Components of UPVC Door Locks

UPVC door locks consist of multiple components that work together to provide security. The main parts include the cylinder, gearbox, and multipoint locking mechanism. These components combine to offer a high level of protection against forced entry, making them an ideal choice for home security.

Types of UPVC Door Locks

Euro Cylinder Locks

Euro cylinder locks are the most common type of lock used in UPVC doors. These locks consist of a cylinder that can be easily replaced if needed.

They are available in various security levels, with anti-snap, anti-drill, and anti-pick features. Euro cylinder locks can be used with different types of door handles, offering versatility and ease of use.

Multipoint Locking Systems

Multipoint locking systems are an essential component of UPVC door locks. They provide multiple locking points along the door’s edge, ensuring that the door is securely fastened to the frame.

Multipoint locks are designed to work with a central euro cylinder lock and can significantly enhance the security of your UPVC door.

Mortice Locks

Mortice locks are less common in UPVC doors but can still be used in certain situations. They consist of a lock body that is installed within the door and a keyhole on the exterior.

Mortice locks provide a high level of security, but they require professional installation due to the need for precise cutting and fitting.

Regular cleaning and lubrication are usually all that is required to keep your UPVC door lock in top condition.

Choosing the Right UPVC Door Lock

  • Security Rating

When selecting a UPVC door lock, it’s essential to consider the security rating of the lock. Look for locks with British Standard (BS) or Sold Secure ratings, as these have undergone rigorous testing to ensure their effectiveness against forced entry attempts.

The higher the rating, the more secure the lock.

  • Size and Compatibility

It’s crucial to choose a UPVC door lock that is compatible with your door’s dimensions and existing fittings. Measure the thickness of your door, the distance between the handle and keyhole, and any other relevant dimensions to ensure that the lock you choose will fit correctly.

If you’re unsure about which lock is suitable for your door, consult a professional locksmith for advice.

As mentioned earlier, there are different types of UPVC door locks, including Euro cylinder locks, multipoint locking systems, and mortice locks. Consider the type of lock that will best suit your needs and preferences.

Euro cylinder locks are versatile and easy to replace, while multipoint locking systems provide multiple locking points for added security. Mortice locks are less common in UPVC doors but can offer a high level of security if properly installed.

  • Budget

UPVC door locks come in a range of prices, depending on their features and security ratings. It’s essential to strike a balance between affordability and security when choosing a lock.

While it may be tempting to opt for the cheapest option, remember that investing in a high-quality, secure lock can save you money in the long run by reducing the risk of break-ins and the need for frequent replacements.

Installing and Maintaining UPVC Door Locks


Proper installation is crucial to the effectiveness of your UPVC door lock. While it is possible to install a UPVC door lock yourself, it’s generally recommended to hire a professional locksmith to ensure a secure and accurate installation.

A professional will have the necessary tools and expertise to fit the lock correctly, reducing the risk of potential security vulnerabilities.


To keep your UPVC door lock in optimal working condition, regular maintenance is necessary. This includes cleaning the lock and surrounding area, as dirt and debris can accumulate and interfere with the lock’s functioning.

Lubricating the lock with a suitable lubricant is also essential to ensure smooth operation and prevent wear and tear.
