Cylinder lock core GERDA WKE1S03035 brass 30–35 mm 3 keys

GERDA WKE1S03035 is a brass cylinder lock core with an adjustable length of 30–35 mm supplied with three keys. It is designed for euro-profile door locks and provides mechanical security using a pin tumbler mechanism. The cylinder fits into compatible mortise and multipoint locking systems and is intended for replacement or upgrade of existing cylinders where a 30–35 mm core is required.

Advantages

The brass construction offers corrosion resistance and long-term durability in typical indoor and sheltered outdoor installations. The adjustable 30–35 mm length allows flexible fitting in doors with slightly different thicknesses without the need for additional adapters. Supplied with three keys, the cylinder provides immediate operability and convenient key distribution for household or small business use.

• Residential apartment and house doors with euro-profile cylinders
• Commercial interior doors and offices requiring standard mechanical locking

How to use

Measure the required cylinder length from the door faceplate to the inner escutcheon before installation to confirm 30–35 mm compatibility. Remove the retaining screw from the existing lock, withdraw the old cylinder, and insert the GERDA brass cylinder until it aligns with the fixing hole. Secure the cylinder with the retaining screw and check smooth operation of the supplied keys in both directions. For multipoint locks, ensure correct alignment with the locking mechanism before final tightening.

Usage recommendations

For reliable performance, clean and lubricate the cylinder periodically with a graphite or dry PTFE lubricant designed for locks; avoid oil-based lubricants. If door thickness or lock configuration differs significantly from 30–35 mm, verify compatibility or consult a locksmith to prevent improper fit or impaired locking function.
