How to Open A UPVC Door When the Mechanism Is Broken

Over the decades, door locks have evolved and come with an extra layer of protection. When you research the modern door type in the market, you will find the most common one is the uPVC (unplasticized polyvinyl chloride) door. The UPVC door is the highly preferred option, but what if its mechanism is broken and you are unable to open the door? Not everyone is knowledgeable enough to know how to open a UPVC door when the mechanism is broken. To help such people, we have come up with an insightful blog that gives you insight into recovering from the stuck UPVC door.

A UPVC door has a multipoint lock mechanism installed; when you lift the door handle, a gearbox positioned inside the door behind the handles throws many rollers, hooks, and bolts, resulting in a secure draft and noise-free door.

Suppose the gearbox or the latch mechanism breaks due to a defect in the closed position. In that case, the door must be manually opened with the help of a professional locksmith to remove the failed component and restore the door's functionality.

Fixing a UPVC door with a broken mechanism requires knowledge, which we have tried to offer with this blog.

Steps to Open a UPVC Door Having a Broken Mechanism

Opening a UPVC door when there is a broken lock mechanism is quite challenging. Following the below-mentioned steps can help you know how to open a door with a broken lock:

Diagnosing the Problem

There could be three different reasons behind the difficulty of opening a UPVC door:

• Jammed Lock: If you see the key turn, but the door still isn't opening, then the internal locking mechanism could be stuck or misplaced.

• Loose or Broken Handle: If the handle seems loose or does not operate smoothly, there may be a problem with the gearbox or internal components.

• Misaligned Door: Difficulty closing or opening the door may be caused by misaligned door hinges or a warped door frame.

Lubricating the Latch Mechanism

Applying lubricant is the best way to improve internal components and lets you open a UPVC door easily. The best way is to spray a silicone-based lubricant into the lock and around the door mechanism. There is a high chance that there is a lot of dirt buildup or corrosion, causing stiffness in the hinge side or the lock.

Using Pliers to Turn the Spindle

Once the lube is applied, you can use pliers to help in turning the spindle. To do this, hold the spindle and rotate the pliers towards the direction of unlocking the door. This strategy can increase leverage, especially if the spindle of internal components is stiff. Remember not to apply force when turning to avoid further damage to the lock and door.

Adjust the Handle

If you see the handle is quite stiff, then it is misaligned. Try lowering the handle while slowly rotating the key. If the handle becomes stuck, avoid forcing it since this may compound the damage.

Inspect and Adjust Hinges Pins

Loose or misaligned hinges might apply pressure to the locking mechanism, thus making it difficult to open the door. Tighten any loose screws on the hinges and make sure the door is level with the frame to release tension.

Examine the Lock Mechanism

If you see that the lock is having a problem, remove the lock, causing you to see if there are any broken components. Before reinstalling, inspect the system for worn-out or jammed components that may require repair.

Manual Unlocking using Tools

Using a flathead screwdriver or a locksmith's tool, gently move the locking points. Insert the tool into the locking region and attempt to manually retract the bolts while providing slight pressure to the door. It will also help in maintaining the latch assembly.

Inspect the Door Alignment

A misaligned door can result in locking troubles. Check to see if the door is sitting evenly in the frame. If the door is not level, adjust the hinges or slightly lift it before attempting to unlock it.

Access Screws

With the spindle in place, carefully check the area surrounding the handle for a cover plate. This panel conceals the screws that keep the handle mechanism in place. Use a flathead screwdriver to gently pull off the cover plate, revealing the screws underneath.

Remove the Interior Cover Plate

After removing the cover plate, you'll have a better understanding of how the handle mechanism works. Keep the cover plate in a secure location; you'll need it when you're ready to repair the handle.

Inspecting the Door Alignment

There is a high chance that improper door alignment may cause UPVC door lock issues. So, do check if the door frame is well-aligned. If not, then adjust the hinges and lift the door to unlock it. Also, ensure there is no excessive force applied to your exterior or interior door.

Call a Qualified Locksmith

Calling up a professional locksmith is always a better idea. The locksmith has all the tools and ideas to open the UPVC door and work on the lock system.
