Put Testkey_A into USB

Where can I retrieve that one from?  And also, is it the same testmode.key for all the pioneer headunits out of curiosity?

Hey guys, first post here.  I haven't been able to find anything on password recovery for the 4200NEX.  What files do I need to put this headunit into test mode?  Also, the SD card slot is behind the screen and requires a password to access so I only have the rear usb port.  Is there a way to get into test mode from that port?

Thanks for any help ahead of time, I just bought this car and the previous owner is unresponsive.
