Compatible tools: Toyota Techstream at the dealer, or locksmith tools whose software lists this model, such as Lonsdor K518 + LKE smart key emulator.

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.
