3-button · 433 MHz · ID8A · FCC ID SEKS-VF123AOB · Part 95440-3Z003
⭐ This is a new genuine factory Hyundai unit: a 3-button smart key for the Hyundai i40 2015-2016, Hyundai part number 95440-3Z003, 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. Hyundai also lists 95440-3Z500 for the same car with a different layout or approval, so match 95440-3Z003 on the original key.
