UPVC Door Security: Multipoint Locking Systems and High-Security Locks

UPVC doors are now one of the most common types fitted across London, valued for their strength and insulation. But the real protection comes from the multipoint locking system inside the door. This mechanism secures the door at several points – top, middle, and bottom – providing far greater resistance to forced entry than a standard single latch.

When a multipoint system is combined with a 3-Star or Ultion high-security euro cylinder, the result is exceptional protection against lock snapping, drilling, bumping, and picking. This upgrade meets British Standard BS3621 and is highly recommended for homeowners, landlords, and property managers who want long-term security and insurance compliance.

At AMZ Locksmith, we specialise in:

UPVC door realignment and gearbox repair

Multipoint lock replacement

3-Star and Ultion lock upgrades

Our team provides same-day service across Acton, Harlesden, Willesden, Wembley, Shepherd’s Bush, Maida Vale, and West London. If your UPVC door is stiff, misaligned, or the handle feels loose, it may need a simple gearbox repair — not a full replacement.

Maintenance Tip: Lubricate the mechanism every few months using graphite or silicone spray to prevent wear and stiffness. Avoid WD-40 or oil-based sprays, which can collect dust and damage internal parts.
