Certifications for exported locks are divided into at least three layers: mechanical safety (e.g., TSA key specifications, strength testing), electrical safety (if electronic components or motors are included), and wireless radio (Bluetooth, NFC, RFID modules). A single certificate typically applies only to a specific model and firmware version; changing a part number or modifying the antenna design can invalidate the certificate. When comparing certificates, buyers should verify that the model, module manufacturer, and firmware version on the certificate match the actual shipment.

Certificates are tied to a specific model, firmware, and module version. Once a product is revised, the number published on the website becomes invalid. For buyers, rather than relying on a list of certificates on the website, it is better to request from the manufacturer, at the RFQ stage, copies of certificates and test reports that correspond to the model being quoted. When interpreting salt spray and life test reports, look at the test duration, pass/fail criteria, and sample batch number, not just the word "passed." Certification costs and timelines vary significantly depending on the laboratory, product complexity, and whether retesting is required, so they must be confirmed based on the actual specifications.
