Access control enables you to control who has access to your building. Although locks and keys also allow you to secure your building, when keys are lost or stolen, the inconvenience and expense of changing locks and re-issuing keys can be high.
All businesses have assets that need to be protected from theft. There is also the issue of protecting staff and their property. It is common in buildings that are secured by locks and keys for doors to be left unlocked all day. This increases the risk of theft. Access control can help to reduce these risks.
