## Long description

Replacement cylinder lock core SYNOLOGY LOCK CYLINDER D6 30/35mm Nickel is an asymmetric cylinder designed for door locks that require a 30/35 mm profile length. The cylinder provides mechanical key operation with a nickel finish and is intended as a direct replacement part for compatible residential and light commercial lock cases. Its dimensions allow installation where a 30 mm inner / 35 mm outer configuration is required.
Advantages
The SYNOLOGY D6 cylinder offers precise mechanical operation and a durable nickel-plated exterior that resists corrosion and wear in normal indoor and sheltered outdoor conditions. Its asymmetric 30/35 mm design enables compatibility with many standard lock bodies that require different inside/outside lengths. The cylinder core is manufactured to provide a consistent key action and straightforward replacement without modifying the existing lock case.
Suitable for
 Residential entrance and interior doors with a compatible asymmetric 30/35 mm profile
 Light commercial doors such as offices, storage rooms, and service areas
 Replacement of worn or damaged cylinder cores in existing lock cases
 Situations requiring a mechanical keyed cylinder rather than electronic or smart locking
Key specifications
 Cylinder type: asymmetric profile core
 Profile length: 30 mm (interior) / 35 mm (exterior)
 Finish: nickel-plated
 Operation: mechanical key
 Typical applications: residential and light commercial doors
How to use
To install the SYNOLOGY D6 cylinder, remove the retaining screw from the lock case with the door in the proper position, withdraw the existing cylinder, and insert the replacement cylinder so that the cam aligns with the lock mechanism. Secure the cylinder by tightening the retaining screw while verifying smooth key operation from both sides. Ensure the door is held in the correct orientation during fitting to avoid misalignment; if the cylinder does not seat correctly, re-check the profile length and cam position.
Usage recommendations
For reliable performance, use the cylinder in doors with compatible lock bodies and avoid exposing the nickel finish to prolonged direct weathering without adequate shelter. Periodically apply a graphite or silicone-based lubricant to the keyway to maintain smooth operation and inspect the retaining screw and cam for secure fitment after initial installation.
