This is a common question we get asked throughout the Bristol area, “why won’t my composite door lock properly?”. This happened yesterday with a customer who call City Locksmiths Bristol from Clifton (BS8), an area we service regularly.

So, if you find your composite door isn’t locking properly, there are generally several factors that could be causing the issue. Here are some common reasons and potential solutions you can try yourself, but we usually find that as the security of your home is very important, its better to call a professional locksmith for help:

  1. Misalignment of the Door
  • Symptoms: The door doesn’t fit snugly into the frame, or the lock doesn’t line up with the strike plate.
  • Solution: Adjust the hinges or strike plate. You may need to tighten or loosen screws or reposition the strike plate slightly.
  1. Warping or Swelling
  • Symptoms: The door may be difficult to close or might not fit the frame properly.
  • Solution: Check for warping or swelling due to damp / hot weather conditions which can happen in coastal or estuary areas around Bristol. If the door is swollen, you might need to wait for drier conditions or consider weatherproofing solutions. In severe cases, planing the door might be necessary.
  1. Debris in the Lock or Mechanism
  • Symptoms: The lock mechanism feels gritty or doesn’t turn smoothly.
  • Solution: Clean the lock and mechanism. Use a suitable lubricant (e.g., graphite powder or lithium grease) to ensure a smooth operation.
  1. Worn Out or Damaged Lock Components
  • Symptoms: Key turns but the lock doesn’t engage, or the lock feels loose.
  • Solution: Inspect the lock for wear and tear. Replace any damaged or worn-out components.
  1. Incorrect Door Lock Installation
  • Symptoms: The lock has never worked properly since installation.
  • Solution: Verify that the lock was installed according to the manufacturer’s instructions. If not, you might need to reinstall or adjust the lock.
  1. Temperature Changes
  • Symptoms: The door locks fine at certain times of the day or year but not others.
  • Solution: Seasonal adjustments might be necessary. For significant changes, consider solutions that account for expansion and contraction of the frame and door.
  1. Faulty Handle or Mechanism
  • Symptoms: The handle feels loose, stiff, or doesn’t return to its original position.
  • Solution: Tighten or replace the handle. Ensure the mechanism is correctly engaged. We do advise calling Nick at City Locksmiths Bristol to ensure the lock used and how it is fitted will meet your insurance requirements.
  1. Incorrect Door Furniture
  • Symptoms: The door handle, lock, or other hardware doesn’t fit correctly.
  • Solution: Ensure all components are compatible and correctly installed.

Troubleshooting Steps:

  1. Inspect Alignment: Check if the door aligns with the frame and if the latch fits into the strike plate.
  2. Check for Obstructions: Ensure there’s no debris or obstruction in the lock or strike plate.
  3. Lubricate Lock Mechanism: Apply a suitable lubricant to the lock mechanism and keyhole.
  4. Tighten Screws: Tighten any loose screws on the hinges, lock, and handle.
  5. Test the Key and Handle: Ensure the key and handle work smoothly without excessive force.
