Cylinder lock SYNOLOGY 50×50 mm matte nickel, long keyway, 3 keys

Cylinder lock SYNOLOGY 50×50 mm in matte nickel is a double-sided long-profile cylinder designed for doors that require 50 mm projection on each side. The lock provides mechanical key-operated access control and comes supplied with three keys. Its matte nickel finish offers a discreet, low-reflective appearance suitable for a variety of residential and commercial interiors. The long keyway accommodates doors and fittings that need extended cylinder length for proper installation and secure operation.

Advantages

The SYNOLOGY cylinder lock features a symmetric 50×50 mm length that simplifies replacement and installation in doors with equal projection on both sides. Supplied with three keys, it allows immediate use and a spare set for users. The matte nickel surface resists visible fingerprints and blends with contemporary hardware. The long keyway design supports installation in thicker doors or where escutcheons and fittings require extra clearance, while the mechanical cylinder construction ensures reliable manual locking and unlocking without electronic dependency.

Suitable for

• Residential entrance doors with central 50 mm projection each side
• Office doors requiring mechanical keyed access control
• Utility and storage rooms where a long-profile cylinder is needed
• Door replacements where the existing cylinder length is 50×50 mm

How to use

Measure the existing cylinder length and door thickness to confirm compatibility with a 50×50 mm cylinder before installation. Remove the old cylinder following standard door lock disassembly procedures, insert the SYNOLOGY cylinder into the lock case, align the cam and secure the fixing screw. Test the keys to ensure smooth turning and proper latching from both sides. If the cylinder binds or the door hardware restricts movement, verify alignment and screw tension and make minor adjustments as needed.

Usage recommendations

For reliable long-term operation, keep the cylinder and keys clean and periodically apply a graphite or silicone-based lubricant designed for locks. Do not use oil-based lubricants that attract dust. Keep one of the three supplied keys as a spare in a safe place and consider ordering additional keyed copies from an authorized locksmith if duplicate access is required.
