Turn the smart-lock counter into a door-fit station
The most useful item beside a demonstration lock may be a measurement card. It helps shoppers understand whether they are choosing a suitable lock or merely a convenient unlocking method for the wrong door.

Ask for the right photographs
Request views of the door edge, existing lock and inside clearance, with measurements where needed. A customer should not have to know technical vocabulary to provide information that makes a useful first recommendation possible.
Explain fit separately from features
Fingerprint access or a phone key does not resolve a physical mismatch. Use the exact regional model’s installation documentation; for example, Aqara publishes a U100 specification page with door compatibility information.
Make the next step simple
Offer a door-fit review before the final hardware quotation. If you want to sell locks through a North American store, ask HomeTech about a demonstration fixture and a photo intake process that staff can use consistently.
Before you buy
