Programming & Compatibility

This transponder key requires mechanical cutting and vehicle-specific immobilizer programming before use.

The TR47 / TOY43 mechanical profile was used across several Toyota transponder generations, so a matching TR47 blade alone does not confirm electronic compatibility. The vehicle must specifically use the Texas ID 4C transponder system.
