⭐ Built for the Honda Accord 2018-2020, this 4-button smart key is a new genuine factory Honda unit of part number 72147-TVA-H2, running 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 72147-TVA-A01, 72147-TVA-A11, 72147-TVA-A21, so the part number, not the FCC ID, decides the order.
