Repeated key presses or no key presses on 2016 MacBook Pro. What to do?

Question

macbook

Hello! There is a macbook pro 16 years old 13 inches without a touchbar. As you know, this model is still with the first version of the butterfly. And it is problematic for me, like for many:
- Some keys every other time (or maybe 1 out of 50 times) are printed 2 or 3 times (the record is 4 times) - "U", "K", "E", "A", "O" and some more (they have duplicates less often)
- Some keys sometimes do not recognize pressing at all (often cmd, rarely shift)
Knowing that Apple recognized the problem and created a program to replace keyboards, I went to an authorized service center, where they took my laptop away for a week, and then returned it with the verdict "the problem was not confirmed." According to the worker: "The engineer presses each key once. If it does not duplicate characters, there is no problem." Then I spent 20 minutes sitting next to the SC employee proving to him that there was a problem. He reluctantly agreed that the keys were duplicated and sent me back for another 7 days. Then he said that "we cleaned the keyboard", but the receipt once again flaunted "the problem was not confirmed." And of course, when I got home, I again began to receive duplicate keys.
The question is, is there anything that can be done? It is unrealistic to work on a laptop, and the SC says that the problem is not guaranteed and does not fit the program.
Question number 2 - I heard somewhere that the old butterfly keyboards of the first version are immediately changed to the second version. But in the SC they told me that it was technically impossible, and if they change according to the program, then only for the same one. Who is right?

Answer 1

The scatter of defective buttons is clearly not random, you are mistaken.

Answer 2

repair / replacement is meaningless, after replacement everything will start to repeat.
the only solution is -> buy an external keyboard and carry it with you (sad but true, Apple created absolutely not practical laptops)

Answer 3

And what are the settings for "auto-repeat keys" and delay ??
