Winkhaus Lock Problems

Common Problem with Winkhaus Locks

Recently, an individual shared their experience after purchasing a new flat equipped with a ‘Wink Haus’ lock and mechanism, which was approximately 2 years old. The problem described was that, while the handle could be lifted from the inside to engage the top and bottom latches, no such action was possible from the outside.

Potential Issues and Diagnostics

1. Key Locking Method: One of the first steps in troubleshooting is to try locking the door with the key from the outside, both clockwise and counterclockwise.
2. Handle Examination: There should be a handle on both the interior and exterior of the door. The exterior should ideally have a key lock, while the interior might have a thumbwheel for easier access.
3. Spindle Issues: Winkhaus locks might have either a split or solid spindle. A split spindle would mean that the inner and outer handles operate differently, which seems to be the issue here. If the outside handle is ineffective, it might be a spindle issue.
4. Safety Regulations: Building regulations often require flat doors to be accessible without a key from the inside. This ensures quick evacuation during emergencies. A thumbwheel on the inside is a common feature to satisfy this requirement.

Potential Solutions and Steps

1. Cylinder Manipulation: Some have found success by removing the cylinder, adjusting it, and then replacing it. This might resolve the locking issue if there’s any misalignment.
2. Lubrication: Before considering a more invasive approach, try lubricating the lock mechanism with WD-40. It might just be a matter of some jammed components.
3. Inspect the Handle and Spindle: There’s a possibility that the split rod or spindle is malfunctioning or wasn’t installed correctly. Removing the handles to inspect could provide insight. Look for signs of damage or misalignment.
4. Seek Professional Help: If the issue remains unresolved, it’s advisable to consult with a locksmith. They can provide an expert assessment and determine if there’s a need for component replacement.

Resolution

In the discussed case, the individual eventually sought the expertise of a locksmith. The diagnosis revealed that the split rod was not functioning as intended, suggesting a possible installation error. Fortunately, the locksmith was able to rectify the problem, restoring full functionality to the lock.

Final Advice

Should anyone experience similar issues with their lock in the future, it might be beneficial to consult with experts familiar with such mechanisms. Sometimes, reaching out to professionals from related industries, like double glazing technicians, could provide a cost-effective solution compared to locksmiths.

In conclusion, while Winkhaus locks are robust and dependable, like any mechanical system, they can experience wear, misalignment, or installation errors. Regular maintenance, periodic inspections, and seeking expert advice when in doubt can ensure that your door remains secure and functional.
