Watchdata Automotive Digital Key System Security Testing: Intelligent Travel, Safe Journey Together

07/31/2025


In the wave of rapid development of intelligent connected vehicles, the automotive digital key system — the “intelligent nerve center” connecting people and vehicles — must deliver safety, stability, and a seamless user experience, as these factors are directly tied to the travel security and trust of millions of car owners. Relying on its testing capabilities covering all scenarios and all technical dimensions for automotive digital key systems, Watchdata safeguards the car owner experience. From functional verification to security protection, we provide solid guarantees throughout the full lifecycle for automakers, making intelligent travel safer and more reliable.


Covering Full-Stack Technologies, Building a Solid Functional Foundation

Watchdata has a deep insight into the core logic of digital key systems and has built an all-dimensional testing system from basic functions to extreme scenarios.

Full scenario coverage:

Whether it is the most basic remote/near-field door/trunk unlocking and locking, the safe and accurate verification of vehicle startup identity, or the complex multi-user hierarchical permission management and temporary authorization time limit control, thousands of carefully designed test cases are like a woven protective net, ensuring that every functional detail has undergone rigorous testing.

Stability in abnormalities:

By deeply simulating extreme working conditions such as low battery and network interruption, we strictly verify the functional degradation performance, ensuring that core functions remain stable and reliable in adverse situations, and every response is accurate, so that users are not afraid of sudden challenges.


In-Depth Research on Wireless Communication, Breaking Through Connection Barriers

The “smart interaction” of digital keys highly depends on the seamless connection of wireless communication technologies. Watchdata has been deeply engaged in cutting-edge technology fields such as Bluetooth, NFC, UWB, and SparkLink for many years, forming unique testing methodologies and profound technical accumulation.

Bluetooth communication:

We not only realize the stability verification of full coverage in the real distance of 0-50 meters but also strictly test the anti-interference ability in the complex “signal maze” with dense Wi-Fi/Bluetooth devices, ensuring that communication is always reliable.

UWB technology:

Through centimeter-level high-precision positioning testing, we completely eliminate the risk of false unlocking and accurately verify the priority judgment logic in scenarios where multiple keys coexist, ensuring a safe and orderly interaction experience.

NFC testing:

Full-angle induction without dead angles, compatibility verification of multi-form carriers, ensuring that every wireless connection is stable, reliable, and within reach.


Upgraded Security Protection, Building an Impregnable Fortress

Security is the lifeline of automotive digital keys. Watchdata has set up a professional vehicle security testing team to conduct comprehensive security tests on products, including hardware, systems, data, applications, passwords, communications, and software upgrades. Every link is strictly checked to accurately identify potential vulnerabilities in the system, building an indestructible “digital defense line” for vehicle safety.


Global Compatibility Verification, Adapting to Infinite Possibilities

Facing the complex ecological challenges of multiple terminals and multiple systems, Watchdata has built a global compatibility testing matrix covering “mobile phones – vehicle machines – third-party software”, laying the foundation for the unimpeded operation of automotive digital keys.

Device side:

Seamlessly compatible with all iOS and Android version iterations, as well as various mainstream smart watches and dedicated terminals, ensuring successful cross-device connection at one time and consistent functional experience.

图片

Vehicle machine side:

Deeply connect core modules such as the central control system, BMS, and ECU, strongly bridge the gap between system versions, and eliminate functional hidden dangers. Ecological side: Proactively verify the potential impact of third-party software (such as mobile phone permission management tools), ensuring that digital keys can ‘thrive’ and ‘seamlessly integrate’ in thousands of ecological environments.

Polishing the Ultimate Experience, Defining New User Standards

With user experience at the core, Watchdata has established an evaluation system combining quantification and qualitative analysis. Strictly control the delay of unlocking/starting instructions within 1 second to ensure timely feedback when the network fluctuates; verify the system fluency through tens of thousands of repeated operation tests to eliminate stutters and false triggers; optimize the friendliness and guidance of prompt information for scenarios such as insufficient power and invalid permissions, allowing every user to easily control intelligent travel.


Tempering in Extreme Environments, Coping with Thousands of Working Conditions

The complexity of vehicle usage scenarios requires testing to cover extreme environments. Watchdata verifies the stability of wireless modules in high and low temperatures ranging from -40℃ to 85℃ and high humidity environments above 95% RH; ensures the dual reliability of hardware and functions through vibration tests simulating driving bumps; tests the signal anti-interference ability in areas with strong electromagnetic interference such as substations and high-voltage lines; ensures the continuous effectiveness of remote control functions in scenarios such as weak networks, disconnected networks, and 4G/5G switching. Regardless of the environment, the digital key can be “as stable as a rock”.


Empowered by Intelligent Testing, Accelerating Product Iteration

To meet the needs of rapid iteration in the automotive industry, Watchdata has introduced automated and intelligent testing technologies. Build an automated framework based on CANoe and TSmaster, combined with self-developed CARDIDE tools, to realize the automation of functional regression and performance monitoring; accurately test the system load capacity by simulating user concurrent scenarios with a virtual device cluster; quickly locate the root cause of occasional failures by in-depth analysis of CAN bus logs, APP logs, and wireless module logs, shortening the testing cycle by more than 30% and helping automakers accelerate product launch.


Guided by Compliance Standards, Based on the Global Market

Keeping up with international and regional standards, Watchdata ensures that test results are recognized globally. Strictly follow industry technical specifications such as CCC, ICCE, ICCOA, and ISO 21434, adapt to the internal standards of well-known automakers, and meet regional regulatory requirements such as European UWB frequency restrictions and GDPR data privacy, providing automakers with a “one-stop compliance pass”.


Looking to the Future, Joining Hands to Create a Safe Future

From functional verification to security protection, from user experience to global compliance, Watchdata has won high trust from customers with its professional, comprehensive, and innovative testing capabilities, comprehensively guarding the quality of automotive digital key systems. Looking to the future, we look forward to working with industry partners to help you move towards a safer future in the field of intelligent travel and provide users with a worry-free travel experience.
