The key chip of a BMW motorcycle can be read or copied by removing the key shell, removing the battery, drawing out the chip and using a professional key chip copier. However, attention must be paid to safety during operation to prevent damage to the shell and chip. It is recommended to operate under the guidance of professional technicians to ensure the accuracy and safety of the operation. In addition, in order to protect the safety of the vehicle, do not disclose the copied chip to others.
