How UPVC Multi-Point Locks Work

- Engages locking points
- Turning key operates cylinder
- Cylinder rotates gearbox
- Gearbox shoots deadbolts
- Multiple points secure door
Common failure points:
- Gearbox (10-15 year lifespan)
- Cylinder (wear from daily use)
- Locking points (hooks break, rollers jam)
- Springs (weaken over time)
