Replacing Lock in uPVC Doors - Summary

  • Replacing UPVC door locks is essential for maintaining home security, especially after wear or if there’s a risk of unauthorised key duplication. It involves selecting the right lock type and ensuring it’s compatible with the door and keys.
  • Indications that a UPVC door lock needs replacement include difficulty in key insertion, handle resistance, visible damage, and irregular latch function. Regular replacement, approximately every 7 years, is suggested to uphold security standards.
  • Proper tools are required for lock replacement, such as screwdrivers, Allen keys, and a new lock cylinder. While the task is DIY-possible, hiring a professional locksmith can provide a secure and precise installation, which is beneficial in complex situations.

UPVC Door Lock Basics

Before you get ahead of yourself, let's first run through some of the basics regarding uPVC locks and what features they have.

A UPVC door lock, an integral part of any home security system, is designed to safeguard your home and prevent unauthorised access.

One of its components is the lock barrel screw, which secures the lock in place. But, like any other device, it can wear out over time or become compromised. So, what do you do when this happens?

Indeed, changing a UPVC door lock is not only feasible but also a significant measure to boost your home’s security. This procedure involves removing the old lock and replacing it with a new one.

The significance of changing a lock on a UPVC door lies in its ability to maintain the security of your home, particularly in cases where the previous lock is compromised or there is a potential threat of unauthorised key duplication.

If you ever need to change a uPVC door, it’s essential to ensure the lock is also replaced to maintain optimal security.

Types of UPVC Door Locks

UPVC door locks come in various types, each designed to offer a high level of security. You might have come across terms such as barrel locks, cylinder locks, and those with circular keyways. But what do they mean, and what are their features?

For instance, a Euro cylinder lock, with its intricate internal design, deters break-ins, thus enhancing your home’s security. When you replace a UPVC door lock, ensure you have new door keys compatible with the new lock. Brands like:

  • Avocet
  • Fullex GU
  • Ferco
  • Mila
  • Roto
  • Yale

UPVC doors are known for their high-quality UPVC door locks.

Selecting the Right UPVC Door Lock

Given the multitude of UPVC door lock choices, selecting the right one for your home can be challenging. Choosing a UPVC door lock should be based on your unique requirements and needs.

One key aspect is to ascertain the correct size of the euro-cylinder locks for your UPVC door. A locksmith can help you determine this by extracting the lock and measuring the distance from the end of the cylinder barrel to the centre of the black line on each side.

When to Replace Your UPVC Door Lock

Recognising the right time to replace your UPVC door lock holds equal importance to understanding the replacement process. But what are the signs that indicate it’s time for a change?

uPVC Door Lock and Key Replacement

You may need to consider a replacement if you face challenges in inserting the key into the lock, if there is resistance in the door handles, or if there is difficulty in turning the handle. Other signs include visible damage on the lock, a loose handle, and sporadic functionality of the door latch.

You can attempt to fix a loose door handle if this is the problem, as this can be done with the help of a few tools.

It’s also advisable to replace the lock if the barrel screw is damaged or if the lock has been in use for an extended period and starts to exhibit signs of failure.

While UPVC door locks don’t need regular replacement solely for security purposes, you might want to consider replacing them approximately every 7 years to account for typical wear and tear and to ensure compliance with current security standards.

Tools Needed for Changing a UPVC Door Lock

Replacing a UPVC door lock requires not only a new lock but also the appropriate tools, much like any uPVC door repair. Utilising the correct tools is vital for a successful and secure replacement of a UPVC door lock.

This minimises the risk of damage to the door or the lock mechanism and ensures efficient completion of the task. Some essential tools for replacing a UPVC door lock include:

  • Screwdriver
  • Allen key
  • Pliers
  • Hammer
  • Chisel
  • Drill
  • Tape measure

Having these tools on hand will make the process much easier and ensure that you can complete the replacement without any issues.

So, what do you need? A basic tool kit for replacing a UPVC door lock includes:

  • Phillips-head screwdriver: vital for unfastening screws that secure the UPVC door handles and lock, thus playing a key role in the lock replacement process
  • Compatible lock cylinder
  • Pencil and paper
  • New lock if needed

You’ll also need a new UPVC door lock in addition to the screwdriver and lock cylinder.

Step-by-Step Process for Changing a UPVC Door Lock

So, now that you have all the tools you need, you are ready to replace your door lock.

Changing a UPVC door lock might seem daunting if you’re doing it for the first time. However, with the right tools and instructions, it can be a manageable task.

Here, we will go through each step of the process so that you can change a uPVC door lock whenever you need to.

Removing the Old Lock

The first step in the lock replacement process is removing the old lock from your door. But how exactly do you go about this?

To begin, remove the screw located under the door lock on the edge of the door. This will allow you to disassemble the locking mechanism. Then, slightly turn the key and pull the barrel lockout with a gentle tug while the key is in the unlock position.

After removing the lock faceplate and the door handle, gently extract the old lock mechanism without causing damage to the door or frame.

During the process, remove the door handle by loosening the screws holding it in place with a Phillips-head screwdriver, and slide the interior and outer handle apart.

Follow this by removing the barrel screw located on the side of the UPVC door. After these steps, the barrel lock can be extracted by eliminating the ball bearings located on both sides of the lock.

Installing the New Lock Barrel

Once the old lock is out, the next step is to install the new one. But before you do that, it’s crucial to gather key measurements such as the overall length of the door, the backset, and the distance from the handle to the cylinder.

Design your door

These measurements ensure the new lock cylinder properly fits in the door and functions optimally without compromising security.

To install the new lock, follow these steps:

Step 1: Align Lock Barrel

Align the new lock barrel with the door and insert it into the designated slot, ensuring proper alignment with the door frame and a flush fit.

Step 2: Secure the Handle

Next, you will want to make sure that you have a door handle fitted. To do this, secure the handle in the spindle hole. Make sure to do this for both sides to ensure you can open and close the door from either side.

Step 3: Test the Barrel Lock

Test the barrel by twisting the key to ensure smooth insertion and normal key operation.

Step 4: Tighten Lock Barrel Screw

Insert and tighten the screws at the top and bottom of the handle, but don't screw them too tightly. Once this is done, the process should be completed, and your uPVC door handle will have been replaced.

Note that to replace the lock barrel, it’s essential to have the key. In the absence of a key, the services of a locksmith or a door lock specialist are required.

Enhancing UPVC Door Security

Everyone wants to feel secure in their home, right? Making sure you have a high-security level for your home is important for this.

Replacing Lock on uPVC Door

While changing your UPVC door lock is an essential step toward home security, there’s more you can do to enhance the protection.

There is also the argument of composite doors vs uPVC doors, regarding which material is better and which is superior in terms of security.

Choosing High-Quality Locks

A fundamental step in enhancing your UPVC door’s security is adopting high-quality locks. A high-quality UPVC door lock, like an anti-snap lock, enhances UPVC door security by mitigating lock snapping and providing superior security in comparison to standard locks.

Brands like Avocet or Yale are known for their superior quality and security features.

Adding Additional Security Measures

Beyond selecting high-quality locks, there are additional measures you can take to further enhance your UPVC door security. These may include:

For instance, a UPVC door security chain provides an additional layer of security. It allows the door to be partially opened while maintaining security against unauthorised entry. Other measures, like installing a peephole, can also provide an additional level of security.

You could also consider integrating a supplementary bolt or chain into your UPVC door for an additional layer of protection.

DIY vs. Hiring a Professional Locksmith

Now that you’ve learned the basics of changing a UPVC door lock, the question is, should you do it yourself or hire a professional locksmith?

Although replacing a UPVC door lock by yourself is doable, situations may arise when engaging a professional locksmith could prove advantageous.

For instance, if you’re unsure about the replacement procedure or if you don’t have the necessary key to change the lock barrel, you might want to consider enlisting a professional’s help.

A professional locksmith provides extensive experience and the utilisation of advanced tools, guaranteeing the secure and accurate installation of the lock. While the initial cost may seem higher, in the long run, it can prove more cost-effective.

Troubleshooting Common UPVC Door Lock Issues

Even after proper installation and maintenance, UPVC door locks can sometimes present issues. Being able to troubleshoot these common problems can save you time and unnecessary stress.

Typical issues with UPVC door locks encompass lock snapping, misaligning locks, and sticking door locking mechanisms.

If your UPVC door lock mechanism is sticking or stiff, try applying a silicone-based lubricant into the keyway and subsequently inserting and removing the key several times to assess any improvement.

If the problem persists, it may be advisable to seek the expertise of a professional locksmith.

Maintaining Your UPVC Door Lock

Adequate maintenance of your UPVC door lock guarantees its durability and peak performance. So, how can you maintain your UPVC door lock?

Regular cleaning and lubrication form the cornerstone of UPVC door lock maintenance. It’s recommended to clean and lubricate UPVC door locks at least twice a year to ensure optimal performance.

Regular cleaning of the lock mechanism using a damp cloth and lubrication every six months with a dust-resistant product such as graphite-based oil can ensure smooth operation.

Using UPVC solvent cream cleaners specifically designed for UPVC frames and doors is recommended for cleaning. For lubrication, dry lubricants such as graphite powder and PTFE lubricants are preferable, as oil-based products may attract dust and dirt.
