Shenzhen Zhaoyuan Automobile Technology Co., Ltd.

Shenzhen Zhaoyuan Automobile Technology Co., Ltd. is located in Shenzhen, China and currently lists 14 distinct remote‑control products. The catalogue covers key‑fobs for brands such as BMW, Cadillac, Buick, Audi, Chevrolet, Chrysler, Dodge, Ford, Hummer, GMC and Honda, with button counts ranging from 2 + 1 to 5 and frequencies of 315 MHz and 433 MHz noted in several titles. Each entry is classified under the broader “Remote Controls” category, which in international trade falls within HS Chapter 85 for electronic control devices. The product titles specify the vehicle model compatibility and key form factor - for example, folding keys for Buick New Regal or flip‑style keys for Audi A3 TT. The supplier’s “harbor” trust tier indicates that it is a verified trading entity on the platform.

The remote‑control offerings are presented without any declared certifications, so buyers should treat the list as a technical inventory rather than a compliance statement. Typical automotive remote‑key specifications include a rolling‑code micro‑chip, a CR2032 button cell, plastic housing rated for temperatures from - 30 °C to 85 °C, and an antenna tuned to the listed frequency. In customs filings these items are usually recorded under HS sub‑headings for wireless transmitters, and they are subject to standard import documentation such as CE or FCC test reports when destined for Europe or the United States. The supplier’s product count of 14 suggests a focused portfolio aimed at aftermarket replacement keys rather than a full OEM line.

The catalogue comprises 14 models, each identified by button count and vehicle brand. Examples include a 4‑button BMW CAS4+FEM Smart Key, a 5‑button Cadillac Smart Remote, a 3‑button Audi flip key for the A3 TT, and a 2 + 1 button Hummer remote operating at 315 MHz. Frequencies of 315 MHz and 433 MHz are common in the list, reflecting the two principal bands used in North American and European automotive remote systems. Typical industry grades for such devices involve a rolling‑code security level (e.g., HCS200), a battery life of 2 - 3 years, and an IP‑rated plastic shell (often IP‑54).
