The chip is in the button, at least the security key for pairing is in the sensor chip itself so it is not possible to replace it. The sensor chip is adhered to the button crystal, and the adhesive is stronger than the chip itself, meaning any attempt to pull the chip off WILL destroy the chip, which is thinner than human hair. “Don’t have money” is not good for repairing things. With the “unrepairability” design trend, any complex repair will require tools costing many times more than the device itself, making repairs only economical for larger scale repair shops. Also, if Apple found out you’ve tampered with the device, they will reject ANY repair requests, no matter paid or not.
