Start with the door and use
A home entry door and a business door may have different operating needs. Describe who uses the door, how it currently locks and any reliability problem. Security goals should be considered alongside ordinary operation.
Ask what a proposed product actually changes. Do not rely on a label alone to establish suitability, resistance ratings or restricted-key features. We do not claim certifications or brand authorizations not documented in this project.
