CBC writer John Lancaster tells of a businessman who will copy electronic key fobs for condo buildings for $35 no questions asked. The practice, says Lancaster, seems entirely at odds with the practice of most condominium boards to keep tight control over access to lobbies and other common areas of their home buildings. The concern is aggravated by the Airbnb phenomenon. The quickie rental service in which people come and go from places is feeding demand for such access. CBC Kijiji
