## Long description

The SYNOLOGY LOCK CYLINDER D6 30x35 mm in nickel is a mechanical cylinder designed for replacement or upgrading of standard door and enclosure locks. With compact 30x35 mm dimensions and a nickel finish, this keyed cylinder provides controlled access using the supplied set of five keys. It is suitable for residential doors, small business premises, cabinets and other applications that require a compact profile cylinder for keyed locking.

This cylinder offers a compact 30x35 mm profile that fits narrow or shallow doors and enclosures where standard cylinders do not.

Supplied with five identical keys, the mechanism enables simple keyed access control without electrical components, making it reliable and low-maintenance.

How to use
Measure the existing cylinder dimensions (30x35 mm) before installation to confirm compatibility. Remove the old cylinder by unscrewing the retaining screw from the door edge, pull the cylinder out with the cam aligned, and insert the new SYNOLOGY cylinder ensuring the cam engages correctly. Secure the cylinder with the retaining screw and test all supplied keys to verify smooth operation and correct locking function.
Usage recommendations
For long-term reliable operation, lubricate the cylinder periodically with a graphite or silicone-based lock lubricant and avoid oil-based lubricants that attract dust. Ensure the cylinder length and cam orientation match the door thickness and hardware; if in doubt, check measurements or consult a locksmith for proper fitting.
