Snapped Key

When a key snaps off inside a lock, it can be incredibly annoying. It could also be a security risk since the door may not be locked and make you vulnerable to burglars. There are a few quick fixes you can make to fix the problem and make your door work again.

Be sure to remain calm. If you panic, you could end up pushing the broken key further into the lock.

Then spray WD-40 or another penetrating oil into the lock to help the broken piece slip out more easily. You can also use the screwdriver to break any pieces stuck. If you have a chunk of the key stuck and is not being removed, grab it with a paperclip or another thin metal object and pull it. Both methods are effective, but you need to be careful not to push the damaged key piece further into the keyway.

Some paperclips have grooved edges which can be used as hook extractors. Jigsaw blades can also work well for this.

Finally, a pair of tweezers is a good way to grasp and remove the remaining bit of the broken key.

Be sure to not lose any internal parts within the handle, such as the plates or levers that are on either side of the spindle.

These windows require a handle that acts as an locking device within the window frame. The handle is attached to a rod in the centre that is then activated by a series of cams that look like mushrooms, they lock into window frame keeps. If the dead latch mechanism does not open after the handle has been turned, it is most likely the spindle has been damaged. This could be a frustrating issue.

After removing the wheel, the technician can examine the spindle and identify the cause of the break. This involves breaking down the spindle into its constituent components and carefully observing their general condition, as well as any specific areas of damage or excessive wear. This procedure is usually carried out in a clean room by skilled technicians.

The next step is to clean the damaged spindle. This will remove any dirt or other debris that may be obstructing it from functioning normally. The spindle can be replaced or repaired. If it is replaced, the technician could use an identical dowel size to the original and drill mating holes into both parts of the spindle. This will ensure that the new spindle has an exact fit with the handle.

If the spindle that is damaged is beyond repair, it may be necessary to replace it completely. Home centres sell generic replacements, but if the style of your window is unusual then it will be necessary to find a woodworker or cabinet maker who can duplicate the exact part for you. Once the spindle has been installed, it is connected to the handle. Line up the screw holes on the handle to the existing screws in the frame. Once the new handle is firmly seated you will be ready to operate your uPVC window.
