How to use
Measure the existing cylinder length and profile to ensure compatibility before installation. Remove the existing cylinder by unscrewing the fixing screw on the lock case and withdraw the cylinder while turning the key as required. Insert the GERDA KMZ S40H66 cylinder into the lock case so that the cam aligns correctly, secure it with the fixing screw and check smooth key operation on both sides.

For reliable operation, lubricate the cylinder periodically with a graphite or silicone-based lock lubricant and avoid oil-based products that attract dust. Verify dimensions and compatibility with your door’s lock case and multipoint mechanism before purchase. If you are unsure about installation, use a qualified locksmith to ensure correct fit and secure operation.
