All vehicles can be stolen, but Tesla does make it significantly more difficult. If a thief gains access to a key card or your cell phone, then stealing your Tesla will be simple. Some people have reported their Tesla being stolen while still in possession of all their keys. If your cell phone is set to unlock your Tesla, then be careful leaving your bluetooth on when inside your home with your car parked in your driveway. Your phone could unlock your car while you’re sitting at home, without your knowledge. If you are worried about someone stealing your Tesla, you can activate the “Pin to Drive” feature on your touch screen.  This will prompt every driver to enter a 4 digit pin before the vehicle can be driven.
