Unified Automotive Key Programming Solution for Multi-Vehicle Platforms. KEYDIY KD046 and KD04D Chips are automotive transponder solutions designed for key programming and immobilizer matching across 46-series and multi-type 4C/4D vehicle systems. They are built to simplify workshop inventory structure while supporting stable, cross-platform key programming performance in real-world diagnostic environments where multiple vehicle generations are handled daily.
KD046 Chip — 46-Series Replacement Standard
The KEYDIY KD046 Chip is designed as a stable replacement solution for traditional 46-series transponder applications, offering consistent compatibility across widely used OEM and aftermarket systems.
Coverage Highlights:
Volkswagen, Citroën, Renault, Opel, Fiat, Lancia
Nissan platforms, including Qashqai/X-Trail applications
Geely, Chery, Great Wall (GWM), Zotye, Haima
Mitsubishi, Peugeot, and selected GM models
Additional regional Asian and European coverage
Package:
10pcs per lot

KD04D Chip — Multi-Type 4C / 4D Integrated Solution
The KEYDIY KD04D Single-Mode Chip consolidates multiple transponder formats into a single solution, reducing the need for separate chip categories in mixed-vehicle service environments.
Supported Systems:
Toyota / Lexus: 66, 67, 68, 71, 72G, 4D70 variants (including regional and hybrid applications)
Ford / Mazda: 63, 63+, 83
Subaru / Mitsubishi: 62 Subaru, 82G Subaru, 61 Mitsubishi, 62 Mitsubishi IIII
Chrysler / Dodge / Jeep: 64-series
Motorcycle platforms: Yamaha, Suzuki, Kawasaki (6A, 6B, 69, 62-series)
Additional coverage: Hyundai/Kia 4D70 (80-bit), Epica 4D60, Excelle 70, and other 4C/60-series systems
Package:
10pcs per lot

Workshop Application Value
In mixed vehicle service environments, KD046 and KD04D work as a complementary system, allowing technicians to handle different immobilizer generations without switching between multiple chip categories. This improves workflow continuity in daily key programming tasks and supports more predictable operation across diverse vehicle platforms.
Technical Appendix
KD046: 46-series transponder replacement chip
KD04D: Multi-format 4C / 4D integrated transponder chip
Requires compatible key programming device supporting corresponding transponder protocols(eg. KEYDIY KD-X4, KD-X2, KD-MAX)
Vehicle coverage depends on the immobilizer system generation and ECU architecture
Some vehicle platforms may require online authorization or OEM-level access
Performance depends on tool’s capability and supported programming functions
