Tesla Car Key Fob. Auto lock worked as well as I was leaving my car. If your Key Fob is equipped with Passive Entry, your Tesla will automatically lock and unlock when the Key Fob is within three feet.
So I received the key fob today and so far it's working great. I bought a fob because my phone had naff bluetooth and the fob just works. I had only the key fob in my pocket (no phone or keycard) and the door unlocked with no issues.
When the key fob cloning attack against Tesla's Model S cars first came to light a year ago, the company emphasized that its vehicles have a GPS tracking feature that stymies thieves.
If you use the key fob or card to unlock the car, you'll need to use it again to manually lock the car when you exit.
This leather wrap for the Tesla Model S key fob is an excellent fit - not too tight and not too loose. I carry it every day, on the same car ring I have my wifes BMW car key that has keyless entry. It took a while to get my car associated to my Tesla account because I bought my car used.
