Xhorse 8A Adapter Was Bind to Other Device?

Problem:

I need to program key for my Toyota RAV 4 2016, lost all keys using xhorse vvdi mini obd tool and 8A non-smart key adapter. But the app says the adapter was bound to other devices. Any solution?

Solution:

8A adapter can only be bound to 1 xhorse device (key tool max pro, vvdi2, key tool plus or vvdi mini obd tool).
Must use the adapter with the device already combined.

For example, if bind 8A control box adapter with vvdi2, you cannot use it with mini obd tool.
