Keys represent access rights to different facility areas, cars, etc.
From a security point of view, it is very important that only the right people have access to the specific keys or access cards.
As such keys and valuables have to be stored in a safe place.
Who did use the key at a particular time?
This raises more questions around responsibility and accountability when something happens. Inadequate security enhances the risk of crime.
In case important keys are stored in a messy, labeled key box, and key withdrawals and returns are traced on a manual sign-out sheet or Excel sheet, it takes far lot of time to get the appropriate information, while nobody can prevent taking keys off the cabinet, and you do not know if the key is actually in the cabinet or not.
