I live in Richmond Hill and back in 2008 I had my 2008 Toyota Highlander stolen out of my driveway. Just a few days before it was stolen, I had taken it into the dealership for it's first oil change. The police speculated that someone at the dealership copied my key including the immobilizer chip, then swung by one night, hopped in and drove off in it. Apparently this type of theft is quite common. Now I keep my outdoor lights on at night and have a night vision security camera installed and aimed at my driveway.
After this incident, I was told that you never take your car in for servicing at dealership near your house - it's too convenient for the car thieves that work there.
You live, you learn
