⭐ This is a new genuine factory Lexus unit: a 3-button smart key for the Lexus UX200 and UX250h 2019-2020, Lexus part number 8990H-76350, transmitting at 433 MHz with a DST-AES, ID 8A (Texas Instruments 128-bit) transponder. It is supplied as the key only, without the emergency blade, and is registered over OBD with a diagnostic tool. Lexus also lists 8990H-76010, a different key (North American UX200 / UX250h 2019-2021 3-button key (Lock, Unlock, Panic), 315 MHz), so match 8990H-76350 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 locksmith tools whose software lists this model, such as Lonsdor K518, Lonsdor LKE emulator, EoneBoss TLK1.
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 UX200 and UX250h 2019-2020 smart key is in the tool's supported list before the job.
