It says that target file failed to verify, what does this mean? July 24, 2013 at 4:37 pm #390 Kanda AdminKeymaster Post count: 324 First check the battery, then try loading a small file into it. If you still get the same error it probably means that your keyfob EEPROM has failed and you need a new one.
