Cylinder lock SYNOLOGY 50×65 mm matt nickel, 3 keys

SYNOLOGY Cylinder lock 50×65 mm in matt nickel is a euro-profile mechanical lock cylinder designed for doors that require a 50×65 mm overall length. Supplied with three identical keys, the cylinder provides keyed entry control and is suitable for standard euro-profile lock cases used in residential and light commercial doors. The matt nickel finish gives a neutral appearance that fits a variety of door hardware styles.

Advantages

The cylinder offers a simple mechanical locking solution with three supplied keys for immediate installation and use. Its euro-profile shape and specified length allow compatibility with many standard euro-cylinder door locks. The matt nickel surface resists corrosion and provides a consistent, low-reflective look that blends with most handles and escutcheons. The product is keyed and operated mechanically, requiring no electronics or batteries.

Suitable for

• Residential front and interior doors using euro-profile cylinders
• Light commercial doors with standard euro-cylinder lock cases
• Doors that require an overall cylinder length of 50×65 mm (asymmetric installation)
• Replacements for worn or damaged euro-profile cylinders

When it may not be suitable

This cylinder is a mechanical, non-electronic solution and does not provide remote access, smart-lock features, or integration with alarm systems. It may not be suitable for doors that require high-security certified cylinders or specialized anti-snap, anti-drill, or anti-pick ratings beyond general mechanical functionality. Also ensure the 50×65 mm length fits your door and lock case; incorrect length can affect operation and security.

Key specifications

• Profile: Euro-profile cylinder
• Overall length: 50×65 mm (asymmetric)
• Finish: Matt nickel
• Operation: Mechanical keyed cylinder
• Keys supplied: 3 identical keys

How to use

Measure the required cylinder length on your door before replacing the existing cylinder. Remove the existing cylinder by loosening the fixing screw in the lock case and sliding the cylinder out while the cam is aligned. Insert the SYNOLOGY 50×65 mm cylinder so the cam engages the locking mechanism, secure it with the fixing screw, and test operation with the supplied keys to ensure smooth locking and unlocking from both sides. If necessary, adjust the door position or strike plate to achieve correct alignment.

What to consider before purchase

• Confirm the required overall cylinder length is 50×65 mm for your door
• Verify compatibility with your euro-profile lock case and strike plate
• Decide if a mechanical cylinder meets your security needs or if certified high-security or electronic options are required
• Check whether three supplied keys are sufficient or if additional key copies are needed

Usage recommendations

For reliable performance, install the cylinder with the correct length and alignment, keep the cylinder clean and lightly lubricated with graphite or a recommended lock lubricant, and have spare keys cut to match the originals. For enhanced security, consider upgrading to a cylinder with certified anti-snap or anti-drill features if your door location or insurance requirements demand higher protection.
