Installation/ replacement of door lock cylinder

Fitting or replacing a lock cylinder — 350 CZK. It is changed after lost keys, after moving into a flat behind a previous tenant, and when damaged. The length has to match the door thickness and must not protrude by more than a few millimetres — a protruding cylinder can be snapped off. The technician measures it on site, so you need not work it out beforehand. A standard cylinder comes with three keys; a keyed-alike set for flat and cellar has to be ordered in.
