UPVC Door Lock Highbury

Diagnosing a UPVC Door Lock Fault on the Door

Diagnosing a UPVC door lock fault starts with recognizing common issues, and we're here to guide you through it. Understanding the symptoms can help us pinpoint the problem quickly. Here's how we approach it:

1. Stiff or Dropping Handle: If your handle feels stiff or drops, and the hooks miss the strike, it's likely due to hinge alignment. This is common on older doors that have settled over time.

   We adjust the hinges and lubricate, which usually takes about 20 minutes.

2. Key Issues: When the handle lifts but the key won't turn, or turns without resistance, the gearbox cam or spindle might be worn.

   We replace the gearbox unit from our van, which takes 30-45 minutes.

3. Hard-to-Turn Key: A key that's hard to turn may indicate cylinder pin wear from street-level grit.

   We replace it with a TS007 3-Star cylinder.

4. Protruding Cylinder: If the cylinder protrudes past the escutcheon, it's snap-vulnerable.

   We upgrade to an anti-snap 3-Star on the same visit.

Euro Cylinder Sizing and Anti-Snap Upgrade

When upgrading your UPVC or composite door, choosing the right euro cylinder size is essential for security and functionality. We measure each side from the center fixing screw to guarantee a snug fit. Common sizes in North London include 35/35, 40/35, and 40/40 mm, with longer 45/50 mm for thicker doors on the Drayton Park and Emirates corridor. The cylinder should finish flush or within 3mm of the handle escutcheon to avoid being a snap point.

We fit TS007 3-Star anti-snap cylinders directly from our van. For key control, we offer restricted-key profiles registered to a card, preventing unauthorized duplication. This feature is ideal for Highbury & Islington leaseholders and short-let owners.

Satisfaction is guaranteed with every installation.

When to Repair the Gearbox vs Replace the Whole Strip

Deciding whether to repair the gearbox or replace the whole strip on a UPVC door lock can save both time and money. We need to assess the situation carefully.

If the gearbox is the primary issue, swapping it out can be a quick and cost-effective solution. Gearbox repairs are typically straightforward when we've the right parts on hand, like the Mila Master or Yale Lockmaster.

However, if the lock strip shows signs of wear or damage beyond the gearbox, replacing the entire multipoint strip might be necessary. A full strip replacement guarantees a more thorough fix, especially if misalignment or multiple components are failing.
