## Summary description

Designed for replacement or installation in residential and commercial doors compatible with euro cylinder fittings, providing standard mechanical locking functionality and key duplication options.

## Long description

Euro profile cylinder lock SYNOLOGY 45×55 mm in matte nickel finish is a long-body mechanical lock suitable for standard euro-cylinder door fittings. The lock delivers basic keyed locking and access control for residential or commercial doors. It is supplied with three keys and is intended for installation or replacement where a 45×55 mm cylinder length is required.
Advantages
The long 45×55 mm design provides extended reach for doors with thicker profiles or additional fittings. A matte nickel surface offers a discreet, corrosion-resistant appearance that integrates with modern door hardware. Supplied with three keys, the cylinder enables immediate use and straightforward key duplication if extra copies are needed. The euro profile format ensures compatibility with widely used lock cases and multipoint mechanisms designed for this cylinder shape.
Suitable for
Replacement of existing euro profile cylinders in residential exterior or interior doors
Installation in commercial doors that accept long-body euro cylinders
Doors with thicker profiles, additional reinforcement plates, or escutcheons requiring an extended cylinder length
Key specifications
Profile: Euro cylinder (long body)
Length: 45×55 mm (asymmetric long design)
Finish: Matte nickel
Operation: Mechanical key-operated cylinder
Supply: Includes three metal keys
How to use
Measure the existing cylinder or door thickness to confirm the 45×55 mm size before installation. To replace a cylinder, remove the fixing screw from the door edge, withdraw the old cylinder, insert the SYNOLOGY cylinder aligning it with the locking mechanism, and secure it with the fixing screw. Test the keys in both directions to ensure smooth engagement with the locking cam and proper operation of the door mechanism.
Usage recommendations
For reliable performance, lubricate the cylinder periodically with a graphite-based or silicone lock lubricant and avoid oil-based sprays. Keep duplicate keys in secure locations and consider registered key cutting if controlled key duplication is required. For installations on fire doors, high-security applications, or where master-key systems are needed, verify compatibility with door hardware and local regulations or consult a qualified locksmith.
