An automobile safe that attaches to anchor loops of an automobile seat comprises a safe enclosure, a safe lid, and one or more engaging members. The safe enclosure has one or more apertures through which the engaging members are disposed. The engaging members have a hook on a first end and a fastening device on a second end, wherein the first end is disposed outside the safe enclosure and the second end is disposed inside the safe enclosure. The hooks engage the anchor loops of the seat, and the fastening members secure the engaging members to the safe enclosure. When the safe is closed and locked, the fastening devices of the engaging members cannot be accessed to disengage from the safe enclosure. Because the engaging members cannot be disengaged from the seat anchors when the lid is closed and locked, the automobile safe cannot be removed from the vehicle.
