To advise on the increasing number of housebreakings in summertime, a lock and key service (Schlüssel & Schloss from Austria) wanted to advertise their cost-free home security analyse. They developed a direct mailing which looked like a real crowbar and put the mailing into the frontdoors of various flats and family homes.
43 households requested the cost-free home security check from Schlüssel & Schloss and effectively improved their security at home.
