Cylinder lock insert GERDA WKE1S03535 brass 35-35 mm, 3 keys

GERDA brass cylinder lock insert WKE1S03535 with a 35-35 mm profile is a mechanical locking core designed for euro-profile door cylinders. The insert is made of brass and supplied with three operating keys. It is intended for installation in residential and commercial doors, entrance locks and other door hardware where a symmetric 35/35 mm cylinder length is required. The product provides basic mechanical access control and replaces or upgrades existing euro-profile cylinders of matching length.

Advantages

The brass construction ensures corrosion resistance and reliable mechanical operation under normal use conditions. Supplied with three keys, the lock insert allows immediate use and key sharing for household or small business access management. The euro-profile shape and standard dimensions make it compatible with most standard locks and strike plates designed for euro cylinders. The symmetric 35-35 mm split simplifies installation in doors where equal inner and outer lengths are required.

How to use

Measure the existing cylinder to confirm a 35/35 mm split before installation. Remove the door handle and fixing screw, extract the old cylinder and insert the GERDA brass cylinder until it aligns with the fixing hole. Secure the cylinder with the retaining screw and reassemble the handle hardware. Test the lock operation with each supplied key to ensure smooth rotation and correct engagement of the bolt or latch.

Usage recommendations

For reliable operation, apply a suitable graphite or silicone-based lubricant to the keyway periodically and avoid using oil-based lubricants that attract dust. Ensure compatibility with the door's thickness and lock case; if the cylinder protrudes excessively, choose a cylinder with appropriate lengths. Keep two keys in secure locations and register additional keys with a locksmith if key duplication control is required.
