How to use

To install the ABUS 39343, first remove the existing cylinder by unscrewing the fixing screw located on the side of the door edge. Insert the new cylinder into the lock case, ensuring the cam is aligned correctly so it does not obstruct the insertion. Once the cylinder is flush, reinsert and tighten the fixing screw securely. Test the operation with the provided keys from both sides of the door before closing it to ensure the mechanism functions smoothly.

What to consider before purchase

• Verify the exact thickness of your door and the position of the lock hole to ensure the 50/50mm size is correct.
• Check if your current door hardware is compatible with standard profile cylinders.
• Consider if you require additional key copies beyond the three provided.

Usage recommendations

Regularly clean the cylinder with a dry cloth and avoid using heavy lubricants that may attract dust or debris. If the key operation becomes stiff, use a dedicated graphite-based lock lubricant to maintain smooth movement of the internal pins.
