It has been proven that not all anti-theft doors are safe. The locksmith said that anti-theft doors in ordinary residential areas generally use cross locks, crescent locks, or AB locks, which can be easily opened with aluminum foil and can be opened in just 30 seconds with proficiency.

Qualified anti-theft doors should be made of steel or stainless steel, with a door frame thickness of 1.5mm or more and inner and outer door panels thickness of 0.8mm/0.6mm or more. Some merchants use a thin layer of iron sheet with a hard wooden board sandwiched in between, filled with shredded paper and other materials, to make a certain weight of "anti-theft door", which can be easily pried open.
