Outside Tesla’s factory in Fremont, California on Friday night, Musk showed off the $35,000 Model 3 which has a range of 220 miles (350 km) on a charge that marks a departure from the company’s earlier luxury electric cars.

“We’re going to go through at least six months of manufacturing hell,” Musk told journalists.

When you pick up your new Model 3 electric car, Tesla won't hand you a key, but instead program your phone to unlock the doors and start it up.

For the Model 3, Tesla engineered the car to accept a digital key transmitted through Bluetooth from an owner's smartphone. The car uses the Bluetooth LE standard, which stands for Low Energy, and is supported by most major smartphones.

As a back-up, or for valet access, each Model 3 will come with a couple of NFC cards, which can also unlock and start-up the car. The cards will unlock the door with a tap on the B pillar, and start up the car with another tap between the front seats.

Tesla has not said if there is a mechanical means of entering a car with a completely drained battery. However, that has not been an issue with the Model S or Model X. Given Bluetooth LE's energy requirements and the large size of the Model 3's battery pack, it would be unlikely for the car to have no electricity available.
