Indian OEM opts for
a CCC-compliant
digital key solution
About the Customer
A leading Indian OEM is one of India’s largest automakers and a driving force in the rapidly growing market for electric and connected mobility. With a strong focus on innovation, digital customer experiences, and sustainable mobility, the company continuously invests in technologies that are shaping the future of mobility.
As one of the first automakers in India to introduce a CCC-compliant digital key solution, the Indian OEM is strengthening its position as a pioneer in connected vehicle services and customer-centric innovation.
Fully Digital Vehicle Access
As part of its connected vehicle strategy, a leading Indian OEM wanted to offer its customers a secure, convenient, and fully digital vehicle access experience. The goal was to replace traditional physical keys with a modern digital key solution that enables vehicle access and key sharing via smartphones, smartwatches, NFC cards, and key fobs.
The project presented several challenges:
- Compliance with the current Digital Key Standards of the Car Connectivity Consortium (CCC)
Integration into the Indian OEM’s existing connected-vehicle ecosystem and cloud infrastructure
- Meeting the highest security and quality requirements for digital vehicle access
- Delivering a scalable solution with a significantly shorter time-to-market
In addition to the technical implementation, the project required close coordination among numerous stakeholders, including vehicle hardware suppliers, smartphone ecosystem providers, backend systems, and cross-functional teams across different countries and organizational boundaries.
To successfully implement this ambitious initiative, the leading Indian OEM needed a partner who understood the entire digital key ecosystem –—from vehicle hardware and OEM backend systems to smartphone manufacturers and industry standards.
End-to-End Digital Key Solution
Together with its hardware partner Marquardt, doubleSlash delivered a fully CCC-compliant end-to-end digital key solution that integrates seamlessly into the Indian OEM’s existing architecture.
The solution enables secure digital vehicle access via smartphones, smartwatches, and NFC cards without the need for a traditional physical key—in addition to key fobs.
The implementation follows global CCC specifications, thereby ensuring maximum interoperability across devices, vehicle platforms, and ecosystem partners—while maintaining the highest security standards. At the heart of the implementation is the Digital Key Backend developed by doubleSlash. It manages key provisioning, lifecycle management, friend key sharing, tracking, key deactivation, and security-critical processes.
The cloud-agnostic solution was integrated into the Indian OEM’s existing connected vehicle landscape and designed to operate seamlessly in a variety of deployment environments. The architecture supports deployment on various cloud platforms, such as AWS or Azure, thereby offering the company maximum flexibility for current and future vehicle programs.
A premium, brand-enhancing digital experience that increases customer loyalty and positions the Indian OEM as an innovation leader in the field of connected mobility.
A pioneer in CCC-based
digital key technology in India
