⭐ Built for the Hyundai Elantra 2017-2018, this 4-button smart key is a new genuine factory Hyundai unit of part number 95440-F2000, running 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.
