MACHINE TRANSLATION of QUESTION:
Please tell me if it is possible to unlock the MacBook Air somehow while saving all the information. There is no access to the mail or phone number, there are only documents certifying that the former owner is my dad.
RESPONSE:
Your dad must unlock it. If he has passed away, Apple has a procedure to cover that wher the documentation you have is most helpful. See:

MACHINE TRANSLATION of RESPONSE:
Твой отец должен открыть его. Если он скончался, у Apple есть процедура, которая покрывает это, когда имеющаяся у вас документация наиболее полезна. См.:
