No method guarantees total protection, as some readers have pointed out: “What if someone breaks a window to get to the key?”
This is a legitimate concern, but this type of intrusion carries more risks and generates noise, which discourages most criminals. Furthermore, the majority of burglaries target doors that are poorly locked or have outdated security systems, rather than those offering even minimal resistance.
