If you can’t open or close your uPVC door properly because of a broken lock, it’s far from ideal.

But aside from the huge inconvenience of not being able to get in and out of your home easily, it also presents a security risk as well as a potential fire safety hazard.

 If your uPVC door has a broken lock, you really should address it as soon as possible. 

Depending on the nature of the problem, you may be able to quickly carry out the repair yourself. 

Identifying the problem 

First, you need to determine whether it is the barrel, or the mechanism that is causing the issue. To do this, put your key in the lock and turn it to lock or unlock it as you normally would.

If the key turns and the lock clicks as usual, the issue is with the mechanism and not the barrel. If the key does not turn or there is some resistance, the issue is with your barrel and is reasonably easy to fix. 

Check the handle 

Check the door handle to see if it is loose. If it is, then locate the screw that holds the barrel into place. Tighten it to hold the barrel more securely, this should effectively tighten the handle and fix the problem. 

Replacing the mechanism 

If the key does turn in the lock, the issue lies with your mechanism, which you will need to replace. 

Every door has its own unique gearbox, so it’s important to purchase the right mechanism for your door.

Replacing it is also no small task and, if done incorrectly, could damage your door further. If you are unsure of how to do this, it would be worth contacting a professional to get them to replace the mechanism for you.

From the first moment when Arthur came round to advise, measure-up and quote for the job we felt we were in good hands. And his team of installers provided the best service. I always think that the best test is if something needs further attention and in this case they returned promptly to fix a small issue and nothing was too much trouble. Our new doors have transformed the back of our house and we highly recommend this company for work of the highest quality. Thank you Arthur and team!

We got our back and front doors replaced by E&A Windows and we couldn't be happier with the job they did. Erez was so helpful as took the time to come to our home to give us a quote, explaining all our options thoroughly and clearly without being pressuring in the slightest. The quality of both doors was fantastic and Adrian’s installation was fast and completed to a very high standard. He was also very helpful. We would highly recommend E&A Windows and will definitely use them again for any future double glazing needs. Thanks so much!

Very professional service! During my initial consultation, I was fortunate enough to deal with the owner of the company. He visited my property and spent a few hours talking me through design options and his recommendations. His recommendations were very insightful and ensured my build looked elegant and modern while retaining the functionality required for an active family of 4. The build process was equally professional with the construction team arriving when they said, treating my property with respect and cleaning up after they finished each day...something not often done by today's tradesmen. I've recommend this company to my parents.

I have just had new windows installed by E&A Windows and I must say I was very impressed. Arthur the owner of the company was so helpful and supportive throughout the process. I don't know much about windows so was skeptical at first, but I felt at ease very quickly. The guys who came to fit the windows (John, Christie and Peter) were absolute legends. They were extremely friendly and so so helpful, and the respect they gave me, my elderly parents and our home was exceptional. They took care of our home as if it was their own. I have never come across such professionals, not only did they do a fantastic job , but they went well beyond, seemed like nothing was impossible. They were with us only for 3 days but my parents were actually sad to see them go. I would highly recommend them to anyone looking to fit new windows.
