1. Stuck or Jammed Door Handle – When to Call UPVC Door Lock Repair London Experts
A stuck door handle is one of the most common issues with UPVC doors. It usually happens when dirt or debris builds up inside the latch or when the mechanism becomes misaligned due to temperature changes.
Why it happens:
- Misaligned latch or gearbox
- Broken internal spring
- Rust or debris blocking the handle spindle
How to fix it:
- Spray a silicone-based lubricant inside the handle and latch area.
- Check the alignment of the door with the frame — if it’s sagging, lift it slightly and tighten hinge screws.
- If the handle still won’t turn, the multi-point lock mechanism inside may need replacement.
Pro Tip: Avoid using WD-40 for long-term lubrication — it can attract more dust.
If the handle feels loose or spins freely, call Locksmith in London at 0746 387 3787 — it may indicate a broken gearbox inside the lock case.
2. Multi-Point Lock Not Engaging Properly

- Faulty gearbox or central cam
- Worn locking hooks or rollers
How to fix it:
- Close the door gently, lift the handle, and test the lock.
- Adjust the strike plates to realign with the latch.
- If grinding persists, the internal mechanism likely needs professional servicing.
