Changing the Barrel Lock on the uPVC Door

Tools You’ll Need:

• Screwdriver (Phillips or flat-head depending on the screw type) 
• New lock barrel (cylinder) 
• Tape measure

Steps to Change the Barrel Lock:

Measure the Existing Lock: Before purchasing a new lock barrel, you should measure the old one to ensure the new one fits perfectly. Measure from each end of the barrel to the center of the screw hole. Note these measurements down.

Open the Door: To change the lock, keep the door open during the process to access the lock mechanism easily. 

Locate the Fixing Screw: Find the fixing screw on the edge of the door, level with the bottom of the lock cylinder. This screw holds the cylinder in place. 

Remove the Fixing Screw: Use the screwdriver to remove the fixing screw. Keep it in a safe place as you’ll need it to secure the new cylinder. 

Remove the Old Cylinder: Insert the key into the old cylinder and turn it slightly to the left or right. This alignment will loosen the cam (the central part that turns with the key) inside the cylinder, allowing you to pull the key and cylinder out together smoothly. 

Insert the New Cylinder: Align the new cylinder in the same position as the old one was when you removed it. Insert the key into the new cylinder and turn slightly to align the cam inside. Push the cylinder into the door until it is flush with the door surface. 

Replace the Fixing Screw: Once the new cylinder is in place, replace the fixing screw and tighten it to secure the cylinder. Make sure not to overtighten, as this could damage the cylinder. 

Test the Lock: Test the new lock with the door open to ensure the key turns smoothly without any resistance. Close the door and test the lock again to ensure it locks and unlocks easily. 

Adjust if Necessary: If the lock is not functioning smoothly, you may need to make slight adjustments to the position of the cylinder or the tightness of the fixing screw.

When to Replace your UPVC Door Lock?

Replacing the lock on your uPVC door is an important part of maintaining your home’s security. Here are some key indicators that it’s time to replace your uPVC door lock:

1. Difficulty Locking or Unlocking:

If you find that your key is hard to turn, or if the lock mechanism feels stiff when you try to lock or unlock the door, it might be a sign of wear or internal damage. This difficulty can lead to a key breaking inside the lock if not addressed. 

2. Wear and Tear: 

Over time, locks can wear out from regular use. If the lock looks visibly worn, corroded, or rusty, it’s wise to replace it before it fails completely. 

3. After a Break-In: 

If your property has been burglarized or there was an attempt to force or pick the lock, it’s crucial to replace the lock immediately. Even if the lock appears undamaged, the integrity might have been compromised. 

4. Lost Keys: 

If you lose your keys or they are stolen, replacing your door lock is a necessary precaution to prevent unauthorized access to your home. 

5. Moving into a New Home: 

When you move into a new home, it’s good practice to replace the locks to ensure that you are the only one with access. Previous owners, realtors, or contractors might still have copies of the keys. 

6. Upgrading for Better Security: 

Lock technology improves over time. If your current lock is an older model, upgrading to a newer, more secure lock can provide better protection against break-ins. 

7. Insurance Requirements: 

Some home insurance policies have specific requirements for the types of locks used. Check your policy to see if upgrading your lock can comply with these standards or qualify you for lower premiums.
