Yeah they are desfire but like so many other RFID technology implementers, they are using the security features of that transponder to lock their customers in. They set keys at the factory and create secure applications on the card so that only those cards will work with the cars. That’s how they can sell you a $0.30 RFID transponder for $270.

It’s even worse than that. It is the nut that holds the steering knuckle to the upper control arm which unlike a axle nut isn’t normally castellated and pinned. What it comes down to is the factory not properly torquing down said nut.
edit: I forgot to mention why it is worse. Normally if you have a wheel fall off you still have somewhat predictable control of the vehicle but when the wheel just falls outwards while still being attached can cause unpredictable behavior which can include loss of control especially at high speeds.

Could Tesla disable in some way the VivoKey Tesla Nak applet to stop the pairing of VivoKey Apex based devices with Tesla vehicles without affecting also their official applet and so the official Tesla key cards from pairing?
Technically yes it’s possible but unlikely.
