La voix active is when the subject does the action, instead of receiving the action. In this case all you have to do switch the object and the subject, and change the verb tense from passé surcomposé to passé composé.
The first one becomes : Ils ont réparé ma voiture.
The second one : Mon fils a perdu son chat.
You see that there's one past participate that is remove and the sentence seems to be flip (kinda). Also, sometime you have to make up the subject since it's not explicit like in number 1.
3 Le technicien a réparé notre ordinateur.
4. Ici, nous avons vendu du café.
5. Nous avons ouvert la porte ce matin.
6. Nous avons fermé les livres.
7 Le prof a corrigé ma composition.
8. Ils ont bâti la maison en 1955.
