⭐ This is a new genuine factory Lexus unit: a 4-button smart key for the Lexus LX600 2022-2023, Lexus part number 8990H-78150, transmitting at 433 MHz with a DST-AES, ID 8A (Texas Instruments 128-bit) transponder. Its buttons cover lock, unlock, trunk, panic. It is supplied as the key only, without the emergency blade, and is registered over OBD with a diagnostic tool. Lexus also lists 8990H-78020, a different key (US / North American LX600 and NX 4-button 315 MHz (replaced by 8990H-78024)), so match 8990H-78150 on the original key.

🛠️ 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 a locksmith key programmer whose software lists this model and year.
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 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 LX600 2022-2023 smart key is in the tool's supported list before the job.
