Arduino cannot set lock_bits and fuses from IDE

What is really frustrating you is you do not know what you are doing, so you are throwing garbage into the process trying to make sense out of nonsense.

Fuses can be set from the IDE, but editing any of the .txt control files is not smart. With just a little research and use of avrdude, you can do things correctly. Use an UNO configured as a programmer, or buy one, search for Arduino ICSP programmer.
The UNO sketch is in the examples for the IDE, or use Nick Gammon's:
arduino_sketches/Atmega_Board_Programmer.ino at master · nickgammon/arduino_sketches · GitHub

Command line script for Windows:
Copy 'n Paste Arduino Firmware - Community / Exhibition / Gallery - Arduino Forum
