Nissan Leaf 2018-2019 Smart Key 3-Button
3-button · 433 MHz · ID4A · FCC ID CWTWB1G0168 · Part 285E3-5SA0A
⭐ This is a new genuine factory Nissan unit: a 3-button smart key for the Nissan Leaf 2018-2019, Nissan part number 285E3-5SA0A, transmitting at 433 MHz with a HITAG AES, ID 4A (NCF29A1M) transponder. It is supplied as the key only, without the emergency blade, and is registered over OBD with a diagnostic tool. The same radio approval is fitted to 285E3-5SA1A, 285E3-5SA1B, 285E3-5SA1C, so the part number, not the FCC ID, decides the order.
