    As we originally reported, Tesla has confirmed that accessing and starting the Model 3 can be done through the use of a keycard but also through one’s smartphone.

    The Silicon Valley electric car company has ditched the ubiquitous Tesla key fob in the Model 3 for a pair of near-field communication (NFC) keycards that can be used for accessing the car. The cards are embedded with a tiny chip that acts as a digital signature for the vehicle.

    Since NFC technology generally has a limited transmission range of roughly 4-inches, Model 3 owners will be required to tap the B-pillar to unlock the door, followed by a tap between the front seats to start the car. This would explain why Tesla SVP of Engineering Doug Field was seen placing the keycard inside Model 3’s front cupholders.


    Tesla has also incorporated a digital key that’s transmitted through a driver’s smartphone using Bluetooth LE, a low energy standard for Bluetooth that’s supported by most smartphones. Unlike Tesla’s current keyless entry system that requires drivers to access a sequence of buttons on its mobile app, Model 3 will use a unique bluetooth signal from your phone to unlock the car as you approach it, and start it when you get inside.

    The decision to do away with the Tesla key fob that’s currently being used in the Model S and Model X is seen as a move that allows the company to further cut costs on Model 3 production, and reduce complexity wherever possible.

    We’ve published the full specification list for Model 3 which includes itemized upgrade pricing for its long range 310 mile option.

    It will also allow the entry to be "reprogrammed". The DriveNow and car2go carsharing platforms both use NFC cards to access their vehicles. So switching to NFC will allow the possibility of a Carsharing application where other people with a Tesla Chipcard can access a Tesla that the owner is providing to teslas carsharing. Just as laied out in Elon's masterplan.

    Does anyone know how the car would lock itself if you walk away in both scenarios with phone bluetooth and with NFC cards only?

    Are the Tesla 3 keycards the same size as standard charge/credit/debit cards (8.56 cm × 5.398 cm / 3.370 in × 2.125 in)? Wondering if they will fit in standard wallets and purses, someone stated they were "the size of a Red Card" which I assume is a larger soccer ref card.
