How to use

Installation involves removing the existing cylinder by unscrewing the fixing screw located on the edge of the door leaf. Once the old cylinder is removed, insert the ABUS 54173 into the lock case, ensuring the cam is aligned to allow insertion. Secure the cylinder back into place using the fixing screw, ensuring it is tightened firmly but not overtightened. Test the locking mechanism with the provided keys from both sides of the door before closing it.

What to consider before purchase

• Measure your existing door thickness and the distance from the center of the fixing screw to both sides of the door to ensure the 45/55mm size is correct.
• Verify that your current lock case is compatible with standard profile cylinders.
• Consider if you require additional key copies immediately upon installation.

Usage recommendations

Regularly clean the cylinder with a dry cloth and avoid using oil-based lubricants, which can attract dust and debris. If the key operation becomes stiff over time, use a specialized graphite-based lubricant designed for lock cylinders.
