1. Is it safe to leave the key in the door overnight?
Yes—as long as you do it only at night and all households members know the key is there. It increases resistance to lock-picking from the outside.
2. Could this trap me inside during an emergency?
It shouldn’t. You can remove the key instantly from the inside. However, avoid doing this during daytime when quick exits may be needed.
3. Does this work on all types of locks?
No. Some modern security cylinders are built so the outside can still be accessed even with an inside key inserted. Test your lock to confirm.
4. Will it damage the lock?
Not typically. But leaving a key inside 24/7 can contribute to mechanical wear, which is why it’s recommended only for nighttime.
5. Should I rely on this alone for home safety?
No. It’s a helpful added layer but works best with strong locks, good lighting, and general home-security awareness.
