I do that for my Tesla from anywhere in the world I have cellphone or internet using my iPhone. With the added advantage if the car is in a garage I won't kill anyone with exhaust fumes.Key fobs are here to stay. I personally like them. In the winter when my late wife and would venture into a cold climate I would go to the doorway of the motel, point the fob at the vehicle sitting outside in the parking lot, start the vehicle and the seats and interior temperature would be nice and warm as we went to breakfast.
If the battery in the fob dies you not only cannot open the doors, you cannot start the vehicle after gaining entry. On the vehicles I (own) you open the center console and a small holding slot is located on the front inside of the console. Slid the fob into this slot and the push button start will then work and start the vehicle.
That is not true of any I have owned. All have a designated place on the outside of the vehicle where a dead key fob can be placed and detected. Even when the Toyota had a mechanical key also too.
And then inside the vehicle there is a place where the fob can be placed to start the car. The Prius had a slot in the dash. One puts the fob in a cupholder for Subaru and Tesla.
Something else a lot of people probably do not know. In the old days when cars had generators if you had a dead battery you could jump start the vehicle and drive off and the generator would supply sufficient voltage to keep the vehicle running, if you didn’t use the headlights, heater blower motor, radio etc to get you to a service facility and install a new battery.
The new vehicles of today cannot be jump started and drove off if you have a dead battery. So if you receive a low battery warning you better be looking for a service facility instead if wondering what that means.
Yes they can be. Most can not be driven without a battery but if the battery works at all once the engine is running and alternator turning most can power the alternator's excited fields from the output of the alternator. The alternator's voltage regulator has to be careful not to turn itself off momentarily before the battery can power the fields on next need.
