There may also be insurance consequences. In some cases, insurers can argue that leaving a key in the door constitutes improper security, potentially affecting claims after a break-in.

The Hidden Downsides
Beyond physical security risks, this habit can also erode a household’s sense of vigilance. When people rely on shortcuts, they may become less consistent about locking doors, checking windows, or setting alarms. Over time, this complacency can weaken overall home security.
There are also practical concerns inside the home. Children, pets, or vulnerable individuals may accidentally knock or turn the key, compromising privacy or safety without anyone realizing it.
Emergency Access vs. Real Safety
While quick exits during emergencies are important, modern safety standards don’t recommend compromising lock security to achieve them. Fire safety guidelines typically emphasize locks that can be opened from the inside without a key, ensuring fast escape without exposing the home to intrusion.
A better solution is installing locks designed for this purpose — such as fire-rated or breakaway locks that remain secure from the outside but allow immediate exit from within. This approach balances emergency readiness with proper security.
