Missing magnet on the lock’s motor

One common reason why a Velux window may not lock correctly is due to the missing magnet on the lock’s motor. It is essential to have this magnet in place as it plays a vital role in ensuring the window securely locks shut. When the magnet is missing, the lock mechanism is unable to engage properly, resulting in the window not being able to lock. If you are experiencing this issue, it is important to have a professional inspect and replace the missing magnet to restore the functionality of your Velux window.

Faulty window control mechanism

Another potential cause for Velux window locking issues is a faulty window control mechanism.

In such cases, it is recommended to contact a skylight specialist or a professional technician who can inspect and repair the faulty window control mechanism to resolve the locking issue.

Improper installation of the window

Improper installation of the Velux window can also lead to locking issues. If the window is not installed correctly, it can affect the alignment of the lock and prevent it from engaging properly. This misalignment may cause the window to remain unlocked or unable to lock securely. In such instances, it is advisable to seek the assistance of a professional who can assess the installation and make the necessary adjustments to ensure the window is properly aligned and able to lock without any issues.
