The YouTuber, who goes by the alias Amie DD, is no stranger to ‘body modification'. A couple of years ago, she an RFID tag inserted into her arm so that she could open the front door at her house. Being a software expert, there were probably other things she could do with the chip in her arm too.
So when her Tesla Model 3 arrived, she though that her car's keycard would use a similar RFID technology that would allow her to simply transfer the data from the card to her existing chip. However, it didn't work out hence she had to remove the chip from the card and insert it into her arm.
For those of you who aren't afraid of seeing blood, you can watch her other video whereby she shows us how the chip is inserted into the her arm.
Since then, she has managed to get it to work, as long as her forearm must be about 25 mm from the car’s center console before it will start up.
