Ultimately the idea is to have a single multi-purpose RFID chip where you can write everything you need (car key, house key, office badge, driving licence, bank card) etc...

Key Fob or not ?

Love the key fob. I have the auto frunk installed as well. I love how quickly I can press it to unlock the car for the whole family, open the frunk and open the trunk. I have the key fob mounted in a key ring holder and it clips onto my belt buckle and sits nicely in my pocket. On a rainy day I don't have to take the phone out etc

I have the cnick ring , as I read that the "hackers" can clone your phones Bluetooth and drive away your car.
NFC are not using their UUID for authentication purposes. (or extremely insecure ones from a decade+ ago).
You rather store an cryptographic key or an encrypted certificate on the chip. That's what is read and validated against the card reader after an initial handshake, and cannot be cloned easily.
That's what Tesla uses with a Java applet and a 256bits DH key. Hasn't been defeated so far afaik.
And you can have multiple (different keys) stored on a single chip. Quite different from a universal key in your analogy.

My old S had a key fob and no card or phone access.
It was "cool" but no longer "cool" ... tech moves on and so should you.
My new S has phone, card, and fob. I use the phone all the time. I have a card as backup but never use it (except for valet parking). I've never used the fob... why carry a lump in your pocket?
Definitely buy it mate. You wont regret. I was skeptical as well but i purchased one from Tesla its really good.

Had the key fob for two years, never used it. I do keep a spare key card in my wallet when out as sometimes, but rarely the phone does not unlock.
Yh, you can buy it directly from the Tesla App for £168. I purchased mine from Tesla for £150 back in March. They increased there prices buy £18 now. See the photo attached.

I don't carry any keys so it would be odd to carry a fob again. I carry my key card and usually my phone and also my apple watch with the 3rd party app can unlock and remote start the car with touch screen or siri voice commands
Yes, apple watch is more multifunctional for £300-350 than a key fob costing £150 but again different solutions for different needs! I wouldn’t carry a fob on top of my wallet but people who carry key pouch wont mind a fob!

I meant using the watch instead of fob not replacing carrying mobile. I am yet to see a Tesla driver going around without their phone irrespective of whether they use it to open the car or not!

And of course the best thing about owning a Tesla is it stops you going out and leaving your mobile phone at home!
Maybe a jogger going for his weekly workout.
That's also the biggest issue with the phone key atm. It's easy to forget you left it in the wireless charging cradle, the car should give you a gentle chime or reminder if you've opened the door with the phone still charging inside...
As I mentioned in another post, it would also be completely possible today to emulate the keycard and add it as an NFC card on your Apple Watch wallet. But that requires just a couple hours of dev from Tesla... which they apparently aren't wiling to do just yet...
