Frequently Asked Questions
Q: Who is this knob for?
A: It is for shoppers comparing access control for compatible doors. Confirm door measurements, installation requirements and safe exit operation.
Q: Can I unlock it from anywhere, and is it guaranteed burglar-proof?
A: Neither is established. The source limits app control to wireless range and supplies no security rating or intrusion-prevention guarantee.
Q: Is it suitable as a housewarming or holiday gift?
A: Consider it after checking the recipient's door fit, app compatibility and battery needs. Gift packaging is unspecified.
Q: How should I install and configure it?
A: Follow the actual instructions, test locking and exit functions with the door open and keep an approved backup access method available. Verify fit rather than assuming the source's most-doors wording applies.
Q: Are batteries, a gateway and multiple keys included?
A: Battery is excluded. Gateway inclusion, key count and complete mounting hardware are not itemized.
Q: Is it a STEM kit or a guarantee that all data stays offline?
A: It is access-control equipment, not a STEM kit. The local-storage statement does not establish all app or service data practices; review the actual app settings and privacy information.
