To use the DORMA DC3003, ensure that the existing door hardware is compatible with the Scandinavian profile dimensions. Remove the old cylinder by unscrewing the fixing screw located on the edge of the door, slide out the old unit, and insert the new DC3003 cylinder. Secure it back into place with the fixing screw, ensuring the cam rotates freely and the key operates the locking mechanism smoothly before closing the door.

What to consider before purchase

• Verify that your door lock case supports the Scandinavian profile
• Measure the required cylinder length to ensure a proper fit
• Confirm the door thickness is compatible with the cylinder dimensions

For optimal performance and longevity, avoid using excessive force when inserting the key. Keep the keyway clean and free of debris, and consider using a dry lubricant if the mechanism feels stiff over time.
