Why is my SDL-H1 not locking?
What could cause this issue?
Several factors could contribute to your SDL-H1 not locking:
- Spindle too long: If the spindle is too long, it may not properly engage with the lock mechanism, preventing it from locking securely.
- U-Clip not installed: The U-Clip is crucial for stabilising the spindle and ensuring it remains in place. Without it, the spindle may move around, hindering the locking process.
- Alignment issues: Misalignment of components within the lock mechanism can prevent it from functioning correctly. This could occur due to improper installation or wear and tear over time.
How can I determine whether it’s an installation issue and not a fault with the lock?
- Reset the lock
- Remove the inside Lock Panel from the door
- Power up the Front Lock Panel with an alternative power source such a power bank or laptop
- Notice a Wiring sound
- Check if your door is locked.
- If it is locked, attempt to unlock with 123456#. If it unlocks successfully, that means your lock is not faulty.
If the lock is not faulty, how do I resolve the issue?
- Check your door thickness.
- If your door thickness is less than 35mm, the spindle might be too long. Therefore you will have to trim the spindle. - Make sure the U-clip is installed as per the instructions on the user manual
- Make sure both lock panels are aligned with the door
