| Wireless Connectivity | Bluetooth Low Energy 5.0 or later; optional Wi-Fi, Zigbee, Z-Wave, or Thread gateway support | Wireless protocol specification, interoperability test results, gateway documentation, and range data under open-air and building conditions | BLE is suitable for local mobile access, while Wi-Fi or a gateway is generally required for remote monitoring and cloud administration | High |
| Regional Radio Compliance | Applicable approvals for the destination market, such as FCC requirements in the United States and CE/RED requirements in the European Union | Declaration of Conformity, test reports, radio-module approvals, and product labeling samples | Approval requirements vary by radio technology and destination country; buyers should confirm that certificates cover the final assembled lock | High |
| Material and Chemical Compliance | RoHS and REACH documentation for products entering applicable European and international supply chains | Material declarations, restricted-substance test reports, supplier declarations, and compliance statements for batteries and electronics | Compliance documentation should match the exact product version, including coatings, circuit boards, batteries, and packaging materials | High |
| Mechanical Security | Hardened lock body, protected cylinder or latch mechanism, anti-tamper construction, and documented endurance testing | Mechanical drawings, cycle-test results, security test reports, ingress-protection data, and samples for independent inspection | Electronic access control does not replace mechanical security; the lock should be assessed for forced entry, wear, and emergency override risks | High |
| Weather and Environmental Resistance | Indoor models commonly target IP20–IP44; outdoor models should generally be evaluated at IP55 or above according to installation conditions | IP test report, operating-temperature range, corrosion-resistance results, sealing design, and outdoor installation instructions | IP ratings indicate protection against dust and water under test conditions but do not guarantee performance in every climate or installation environment | High |
| Power and Battery Performance | Low-power operation, replaceable batteries, low-battery alerts, mechanical or external emergency power backup, and clear battery-life assumptions | Battery-life test conditions, standby-current data, low-voltage behavior, emergency-unlock procedure, and approved battery specifications | Advertised battery life depends on access frequency, wireless activity, temperature, battery chemistry, and connected gateway usage | High |
| Data Security and Access Management | Encrypted communication, authenticated firmware updates, role-based administration, audit logs, and secure credential provisioning | Security architecture summary, encryption methods, update policy, vulnerability-reporting process, privacy documentation, and penetration-test summary where available | Buyers should confirm who controls cloud data, how credentials are revoked, and whether the product can operate securely if cloud service access is interrupted | High |
| OEM and ODM Capability | Documented customization process for housing, firmware, mobile applications, packaging, language support, and access-control integrations | Product-change procedure, engineering resources, sample approval workflow, firmware-release process, and integration documentation | Customization can increase tooling, certification, testing, and minimum-order requirements; changes should be frozen before mass production | Medium |
| Indicative Pricing Structure | Entry-level electronic locks often fall around US$25–60 per unit; connected or commercial models commonly range from US$70–250 or more before logistics and integration costs | Tiered quotation, tooling charges, certification costs, software or cloud fees, sample charges, packaging costs, and payment terms | Unit price alone is not a complete comparison; total landed cost may include gateways, subscriptions, spare parts, compliance testing, and after-sales service | High |
| Minimum Order Quantity | Standard products may support lower initial quantities, while customized hardware or firmware often requires higher project volumes | MOQ by model, color, finish, packaging version, firmware configuration, and annual purchase commitment | Ask whether mixed-model orders are permitted and whether pilot quantities can be converted into a production order without duplicate setup costs | Medium |
| Sample and Pilot Lead Time | Approximately 7–21 days for standard samples; customized samples may require several additional weeks depending on tooling and firmware work | Sample schedule, engineering-change timeline, testing milestones, approval sign-off process, and sample-to-production transition plan | A written pilot plan reduces the risk of shipping a product that has not been verified with the buyer’s door types, mobile platforms, or access-control system | High |
| Mass-Production Delivery | Common production lead times are approximately 30–60 days after order confirmation for standard models; customized programs may take longer | Capacity plan, production schedule, component availability, inspection points, shipment window, and delay-escalation procedure | Lead time should be measured from approved specifications and deposit receipt, not from the first quotation date | High |
| Quality-Control Process | Incoming-material inspection, in-process testing, final functional testing, traceability, and documented sampling standards | Quality manual, inspection checklist, batch records, serial-number system, corrective-action reports, and pre-shipment inspection options | Testing should cover unlocking, locking, battery voltage, wireless communication, emergency override, firmware version, and cosmetic quality | High |
| Warranty and Spare-Parts Support | Clearly defined commercial warranty, replacement process, spare-unit policy, and availability of critical mechanical and electronic parts | Warranty terms, failure-rate reporting, RMA procedure, spare-parts price list, repair instructions, and service-level commitments | Global buyers should clarify whether warranty support is handled remotely, through regional service partners, or by return shipment to the manufacturing location | High |
| Software and Firmware Support | Documented firmware-update method, mobile operating-system support, API or SDK availability where required, and a defined end-of-life policy | Compatibility matrix, release notes, API documentation, update security policy, cloud-service terms, and support-response targets | Long-term software support is essential for connected locks because discontinued applications or cloud services can reduce the usable life of the hardware | High |
| International Logistics | Export packaging suitable for electronic and mechanical components, documented HS-code guidance, and shipping options by air, sea, or courier | Packing specification, carton dimensions, gross weight, battery transport documentation, Incoterms, export records, and shipment tracking process | Locks containing lithium batteries may require additional transport documentation and carrier restrictions; confirm requirements before booking shipment | Medium |
