The same radio approval is fitted to 95440-N9500, 95440-N9510, 95440-N9570, so the part number, not the FCC ID, decides the order.

🛠️ Programming instructions

🔌OBD PROGRAMMING - DIAGNOSTIC TOOL REQUIRED

This proximity smart key cannot be learned by hand. It is registered to the car through the OBD-II port with a diagnostic tool.

Compatible tools: the Hyundai dealer diagnostic system, or a locksmith key programmer whose software lists this model and year.
Add key (spare): connect over OBD, enter the immobiliser PIN, then register the new key and every existing key the customer keeps.
All keys lost: the PIN is read or calculated first, depending on platform and tool, then each key is registered.
Blade: cut the emergency blade to the vehicle's key code and test it in the driver's door.
Check coverage first: support depends on the tool's software version and the exact model year. Verify the Hyundai Tucson 2025-2026 smart key is in the tool's supported list before the job.
