## Long description

GERDA WKE1S04040 brass 40-40 mm cylinder lock insert with 3 keys is a double-sided mechanical cylinder designed for standard residential and commercial doors. The 40/40 mm split profile offers a symmetrical fit for doors requiring equal internal and external cylinder lengths. Constructed from brass, the insert delivers corrosion resistance and reliable mechanical performance for everyday locking and unlocking operations. It is supplied with three identical keys and is compatible with locks that accept GERDA profile cylinders.
Advantages
The brass construction ensures durability and resistance to rust in common indoor and sheltered outdoor environments. The 40-40 mm symmetric profile simplifies installation where a centered cylinder is required and reduces the need to modify the door or lock body. Supplied with three keys, the cylinder supports immediate use and basic key distribution. The mechanical design does not require power or batteries and provides straightforward, low-maintenance operation.
Suitable for
 Standard residential entry doors with centered cylinder requirement
 Commercial interior doors with matching cylinder dimensions
 Replacement of worn or damaged double-sided cylinders
 Doors where a brass finish and moderate corrosion resistance are acceptable
Key specifications
 Cylinder type: Double-sided (double cylinder) insert
 Material: Brass
 Length: 40 mm + 40 mm (symmetrical split profile)
 Operation: Mechanical key-operated
 Number of keys included: 3
 Compatibility: Fits door locks accepting GERDA profile cylinders
How to use
Install the cylinder insert into the existing lock body by removing the fixing screw, inserting the cylinder until it seats flush with the rose or escutcheon, and refitting the fixing screw. Test operation by turning the supplied key from both sides to ensure smooth engagement of the bolt or latch. If necessary, adjust the cylinder position slightly to achieve proper alignment with the door hardware. Use only the supplied keys or authorized duplicates cut to the same profile.
Usage recommendations
For reliable long-term performance, avoid exposing the brass cylinder to prolonged direct weather without shelter. Periodic light lubrication of the keyway with a graphite or dry lubricant will help maintain smooth operation; avoid heavy oils that attract dust. When replacing an existing cylinder, confirm that the 40/40 mm symmetric length matches the door thickness and hardware clearance to ensure a secure fit.
