The double-sided keyed design provides consistent locking performance from both interior and exterior sides.

How to use

Ensure the existing lock case and mounting screws are compatible with a 70 mm euro-profile cylinder before removal. Remove the old cylinder by loosening the retaining screw in the door edge and withdrawing the cylinder while the cam is aligned. Insert the Grot cylinder so the cam engages correctly, secure it with the retaining screw and test operation with the supplied keys on both sides. Verify smooth rotation of the key and proper deadbolt or latch movement through several cycles to confirm correct installation.

Usage recommendations

For reliable operation, periodically lubricate the cylinder with a graphite or silicone-based lock lubricant and avoid oil-based lubricants that can attract dust. When replacing a cylinder, check strike plate alignment and door hardware condition to ensure secure locking. Keep spare keys in a safe place and consider rekeying if security is a concern after moving or losing keys.
