🚫 Can I Use Used Modules with Hyundai, Kia, or Genesis?

These manufacturers use modules that are preprogrammed and locked with a Vehicle Identification Number (VIN).
The VIN is written during module initialization and cannot be rewritten or changed afterward.
Especially for security modules, the system will detect any mismatch in the VIN.
If the VIN in the module does not match the vehicle’s VIN, the car will not start.

You cannot use used or salvaged modules for Hyundai, Kia, or Genesis vehicles.
To ensure proper operation, only brand new modules should be installed.
Using a new module will guarantee that the correct VIN is initialized, allowing the vehicle to start and operate normally.

Module Type	Can You Use Used?	Notes
Security Modules	❌ No	VIN mismatch prevents vehicle start
Other Modules	❌ No	VIN is locked and unchangeable

When working with Hyundai, Kia, or Genesis vehicles, it’s important to know that used modules are generally not compatible due to strict security measures.
