There is a Tesla owner named Brandon Dalaly who is a fan of biomodification. He has a chip implanted in his left hand that's used to unlock his home and also store information such as his contact card, medical information, Covid vaccination card, and similar items.
Dalaly recently added to his collection with a larger implant in his other hand: the VivoKey Apex, basically a Tesla Key Chip implant.
He uses that as his key when his Bluetooth key fails or he doesn't have his key card. He just waves his hand to start his Telsa. The chip cost him $300, the implant process was another $100.
