Map doors to roles
List the areas each team needs. Separate tenant access, operational staff, service rooms and management. Avoid giving a broad access level where a limited one meets the need.
Review what already exists
Cylinder families and keyways affect compatibility. Existing master-key arrangements should be reviewed securely by authorized personnel, rather than pasted into an open enquiry.
Define key authorization
Decide who can request keys, approve duplicates and record issuance. A hardware upgrade alone does not replace a clear key-control process.
Prepare for change
Discuss planned tenant changes, additional doors and future buildings. That context helps establish a system hierarchy that can grow in a controlled way.
