The Model 3 Key Fob, which is shaped like a tiny replica of your Model 3
provides an additional method of entering your Tesla vehicle.
It is perfect for owners who don't use their smartphone's phone key feature.
If your key fob has passive entry, your car's doors and trunk will lock and unlock themselves
when it is three feet away. If your Model 3 isn't equipped
you can lock it by pressing the top once, then twice to unlock it. Pressing the front or rear trunks twice will open them.
