There are lots of different lock designs, here are a few of the ones usually found on homes and businesses
🔑 Cylinder Locks
These are probably the most familiar. You’ll often see the keyhole on both sides of the door, with the cylinder sitting inside the handle/locking system.
🔐 Anti-Snap Cylinders
These are designed with additional protection against lock snapping — an important consideration for external uPVC doors. Look for cylinders meeting recognised security standards such as TS007 or Sold Secure Diamond where appropriate.
🚪 Multipoint Locking Systems
Rather than locking at just one point, these systems secure the door at multiple points around the frame. They’re extremely common on modern uPVC and composite doors.
🔒 Lever Operated Multipoint Locks
The handle lifts to engage the locking points before you turn the key. If your handle has started becoming stiff or you need to lift it further than usual, it may be worth getting the mechanism checked.
🔑 Key-Wind Multipoint Locks
These use the key to operate the locking mechanism rather than relying entirely on lifting the handle.
And here’s the important bit…
You often get what you pay for.
So if you’re thinking about upgrading your uPVC door locks, don’t just order something because it will fit.
Get something good and proper that will keep you safe. 👍
I am happy to advise on what you need and all of the options available. You can even book a free consultation.
And if your uPVC door is getting stiff, difficult to lock or generally behaving like it’s had enough of life…
Give me a call before it decides to give up completely. 😂 Just call Paul.
