It's no different than a computer asking you for the correct password when you type in a wrong letter. The difference is, besides the T 800 being far more advance, the T 800 also has no choice but to follow orders, even if the "password" is in correct. So it asked twice, and ultimately followed the orders, or granted you access if it was a computer.

Due to the film's lackluster performance, Dark Fate stands to lose $120 million for the film's partnered studios, including Skydance Media, Paramount Pictures and 20th Century Fox. At the film's conception, each studio had offered up 30 percent of the project's $185 million budget, with China's Tencent contributing 10 percent of the tentpole's production budget. Adding insult to injury, Dark Fate stands to lose even more money ($130 million) if the film fails to gain traction internationally.
Can't say it's surprising can we? I mean it takes a deep Khev-like analysis to find the merits in what they had - and as I said earlier I have doubts that even the writers themselves thought it through to the extent that Khev has. That's not a slight at Khev I hasten to add.
