Mystery Cylinder Lock – How Can I Remove It

[hertsenberg]

Hi everyone,

I’m trying to remove this cylinder lock from my own door, but it isn’t a standard Euro-profile cylinder. There is no obvious retaining screw on the edge of the door, so the usual removal method doesn’t apply.

I’ve attached several photos showing the lock and the surrounding hardware. Can anyone identify this type of cylinder or locking mechanism? Is there a particular trick, hidden fastener, or non-destructive removal method I may be overlooking?

I’d especially appreciate step-by-step advice on removing the cylinder without damaging the door or fittings. If a special tool is required, please let me know what I should look for.

Thanks in advance—I’m very curious to hear what the experts think!

On the edge of the door, remove the long plate, held on by the two screws. Under the plate, in line with the lock cylinder, there should be a retaining screw. Loosening the screw may allow you to unscrew the lock cylinder. Under all that paint, what brand is the lock?
