custom smart lock supplier American

Against the backdrop of the rapid development of the global smart security industry, Chinese smart lock companies are breaking down international market barriers through technological innovation and customized services. Among them, Kerong, with its over 20 years of technological accumulation and global layout, has become a significant customized supplier in the US high-end smart lock market.

1. Technological Foundation: From Traditional Locks to the Entire Smart Electronic Lock Industry Chain

Founded in 2002, Kerong Industrial initially entered the security market with hardware products such as electronic combination locks and steel security cabinets. After more than 20 years of development, it has achieved comprehensive breakthroughs in electronic smart lock technology. Kerong has accumulated over 50 independent intellectual property rights, including 20 national utility model patents and 2 invention patents. Its electronic combination locks have passed the national 3C certification and ISO9001 international system certification, achieving industry-leading levels in core parameters such as static current and anti-static interference. For example, the KR-210 model electronic cabinet lock uses ABS environmentally friendly flame-retardant material and a zinc alloy lock cylinder, can withstand 1470N of lateral static pressure, and has an operating temperature range of -15℃ to 65℃, meeting the needs of use in the extreme climate conditions of the United States.

2. Customization Strategy: Cracking the Code to US Market Access

Kerong's breakthrough into the US market lies in its dual-engine strategy of "customization + compliance." Addressing the stringent fire and explosion-proof requirements of the US commercial building market, the company developed a series of smart locks that have achieved UL94 V-0 fire resistance certification. Their electromagnet drive mechanisms boast a lifespan exceeding 1 million cycles, far surpassing the 500,000 cycles required by the ANSI/BHMA A156.25 standard. In the residential sector, Kerong customized fingerprint locks for high-end communities in California, integrating a decoy password function to effectively prevent password snooping risks. This design was later incorporated into the company's standard product line.

Compliance is key to Kerong's success in the US market. The company established an electromagnetic compatibility laboratory compliant with FCC Part 15 standards, ensuring that product radiation interference values ​​are below 30dBμV/m. Its Bluetooth smart locks are Apple MFi certified, allowing seamless integration with the HomeKit smart home platform. This qualification enabled Kerong to secure orders from Apple's North American supply chain in 2023. Furthermore, Corona conducts cycle life testing on its lock bodies according to the ASTM F883 standard, extending the testing cycle from the industry standard of 50,000 cycles to 200,000 cycles to meet the specific requirements of the US market for product durability.

3. Localized Operations: Building a North American Service Ecosystem

Corona has established a North American operations center in Los Angeles, forming a localized team of 12 engineers to provide full-cycle services from installation training to 24-hour emergency response. Targeting the characteristics of the US construction market, the company has developed modular installation kits, enabling smart locks to be compatible with over 80% of US standard door frames, reducing installation time from 2 hours in traditional solutions to 45 minutes. This "plug-and-play" design won the "Best Innovative Accessory Award" at the 2024 Chicago Construction Expo.

Regarding supply chain optimization, Corona has established a regional warehousing center in Houston, achieving delivery to 90% of the US market within 72 hours. Through strategic partnerships with UPS and FedEx, its logistics costs have been reduced by 18% compared to the industry average. In after-sales service, the company offers a "5-year whole-machine warranty + lifetime maintenance" policy, promising to replace faulty parts within 48 hours. This service standard has become a key factor in its victory over its South Korean competitor, Samsung SDS.

4. Ecosystem Collaboration: From Single-Product Supplier to System Solution Provider

Kerong's US market strategy is upgrading from hardware sales to scenario-based solutions. In 2025, the company customized an intelligent guest room control system for the Marriott Hotel in New York, integrating door locks, temperature control, and lighting modules, achieving low-latency linkage between devices through the Zigbee 3.0 protocol. This system reduced the hotel's energy consumption by 22%, increased customer satisfaction by 15 percentage points, and achieved a project repurchase rate of 80%.

At the technology alliance level, Kerong collaborates with Amazon AWS to develop an AIoT platform, using machine learning to analyze user unlocking habits and provide early warnings of abnormal behavior. Its collaboration with Tesla focuses on the development of smart locks for electric vehicle charging stations, achieving interconnection between "vehicle-charging station-home" through NFC near-field communication technology. These ecosystem initiatives propelled its market share in the US smart lock market from 3.7% in 2023 to 9.1% in 2025.

In 2026, Kerong will continue to invest resources in researching cutting-edge technologies such as 3D structured light facial recognition and quantum encrypted communication. We hope to collaborate with more US companies; Kerong has ample experience and production capacity in smart lock manufacturing.
