How to use

To install the cylinder, first remove the existing lock by unscrewing the retaining screw located on the edge of the door faceplate. Insert the key into the new SYNOLOGY cylinder and turn it slightly to align the cam with the lock body. Slide the cylinder into the mortise lock hole until it is centered. Reinsert and tighten the retaining screw through the door edge to secure the cylinder in place. Test the locking mechanism with the key from both sides of the door before closing it.

What to consider before purchase

• Verify the exact measurement of your current cylinder to ensure the 45x30 mm size is correct.
• Check the thickness of your door to ensure the cylinder length is appropriate.
• Confirm that your door hardware is compatible with standard euro profile cylinders.

Usage recommendations

Regularly lubricate the internal mechanism with a dry graphite spray to ensure smooth key operation and extend the lifespan of the cylinder. Avoid using oil-based lubricants as they may attract dust and debris.
