Define the problem first
Repairing a fault, changing access and updating appearance are different goals. State which outcome matters most.
Check the door and existing fit
Material, thickness, preparation and current hardware shape compatibility. Avoid altering the door before the product is reviewed.
Clarify who supplies the product
Customer-supplied hardware may still need a compatibility review. Packaging, parts and manufacturer instructions should be available.
Keep digital setup private
For smart products, account credentials, codes and network details remain with you. Physical installation does not imply cybersecurity support.
