What Implant Do I Need?

I am looking to purchase my first implant finally after years of following dangerous things and the progress the business has made. I want a chip that I can use for DIY projects including biometric car ignition, door locks, and other similar projects. I really like the Vivokey Spark but from my understanding they don’t function with most, if not all, nfc door locks. I would like input as to which implant would be best suited for me.

door lock would be the xNT - also unlocking your computer, phone, tablet, sharing your vCard, logging into a nfc password safe

I don’t know if there is a HF lock for a car, DT hast only a Kit for the car, which works with the xEM.
