There's a lot said in that statement.
I troubleshot hundreds of keyboard issues over multiple products (two different companies) over my 37-year career as an electronics tech, and keyboard issues were ALWAYS relatively easy to isolate to the component level. Keyboard lines are usually held high, until a key-press pulls it low. It's not rocket science.
Unfortunately, more and more, companies will train someone to swap major parts of a device, and NOT have a technician troubleshoot to component level (cost savings). If this is a one-of-a-kind failure, root cause may not be important. But we hope Siglent would do root cause analysis on failures trends.
It also appears the troubleshooting didn't take place at the manufacturing plant, or the parts would have been available.

Today I conducted another test.
FFT started the calculation from the built-in generator,
waited for the freezing of the readings of the FFT,
removed the probe from the generator, the signal disappeared.
FFT the picture has hung up.
I connected the dipstick to the generator, the signal appeared, the FFT also hangs.
But the buttons do not work either !!!.
That is, this is the case either in the firmware or in the main board.

Bought mine from the actual siglent store and no issues.
dmgr:
if I lived in the USA ... When I bought the oscilloscope, we did not have them in Russia, from the word absolutely. Then they began to sell, but twice as expensive. Our customs can not miss them, because according to our law, only firms can buy them abroad.
Therefore, especially the choice to buy for 350 dollars an oscilloscope with such parameters was not.

Demopool? So you traded a new unit for a used unit? Is that standard Siglent practice? I would not accept this approach myself personally!

"It looks to me like the keypad is bad. I swapped the mainboard and it did not repair it and I did not have any kepads so I gave you another unit from our demo pool."
...so it sounds like they really don't know what the problem was either.
