- 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 immobilizer system generation and ECU architecture
- Some vehicle platforms may require online authorization or OEM-level access
- Performance depends on tool capability and supported programming functions
