🛠️ 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: Toyota Techstream at the dealer, or locksmith tools whose software lists this model, such as Autel APB112 (4D smart key emulator), Autel XP400.
Add key (spare): connect over OBD with a working key present and run the tool's smart key registration through the smart key ECU.
All keys lost: the route depends on the chip generation; newer platforms may need the smart key ECU read on the bench or an emulator before a key can be registered.
Blade: cut the TOY48 emergency blade, sourced separately, 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 Lexus LS430 2004-2006 smart key is in the tool's supported list before the job.
