Cylinder lock insert GERDA WKE1S03045 brass 30-45 mm with 3 keys

GERDA WKE1S03045 brass cylinder lock insert is a removable profile cylinder designed for residential and light-commercial door locking systems. With a combined length range of 30–45 mm, the cylinder is supplied with three keys and fits into standard euro-profile lock cases where this length is required. The brass construction offers corrosion resistance and consistent mechanical performance for everyday door access control.

Advantages

The brass body ensures durability and resistance to environmental effects commonly encountered on external and internal doors. The removable euro-profile design allows fast replacement or upgrade of existing cylinders without altering the door hardware. Supplied with three precision-cut keys, the product supports convenient key distribution and replacement. The simple, standardized shape provides compatibility with a wide range of lock cases and escutcheons that accept a 30–45 mm cylinder.

Suitable for

• Replacement of worn or damaged euro-profile cylinders in residential doors
• Upgrading locks in apartments, houses and small office doors
• Standard door installations requiring a 30–45 mm cylinder length
• Situations where a removable cylinder is preferred for easy maintenance or quick change

How to use

Measure the existing cylinder length from the centre of the fixing screw hole to each end of the cylinder to confirm the 30–45 mm requirement before installation. Remove the old cylinder by loosening the central fixing screw and withdrawing the cylinder while positioning the key as needed. Insert the GERDA brass cylinder into the lock case, align it with the fixing hole and secure it with the central screw. Test the operation of all supplied keys to ensure smooth turning and reliable locking from both sides where applicable.

Usage recommendations

To maintain reliable operation, periodically lubricate the cylinder with a graphite-based lubricant or manufacturer-recommended product and avoid using oil-based sprays that can attract dust. Ensure keys are duplicated only from the originals and keep a spare key in a secure location. For external doors, combine the cylinder with appropriate weatherproof escutcheons and fittings to reduce exposure to moisture and prolong service life.
