During the Detectives flash back, being alone with the Serial Killer; She mentions that she has her hand on her service revolver, the flashback clearly shows she has a semi-automatic handgun, not a revolver.
Not only is Anna trying to pick the deadbolt lock using two picks (as opposed to a pick and a tension wrench or turning tool), she is able to do it almost immediately without turning the lock's cylinder at all.
But this is part of the satire genre, spoofing how thrillers will often have characters easily pick a lock even though in reality it's a skill. Notice how Anna herself was surprised it worked.
