Genuine Lexus remote engine starter remote control, stylish leather-look design. - Brand: Genuine Lexus - Function: Remote engine start + smart key - Number of buttons: 4 buttons - Design: Leather-look finish Thank you for viewing. Remote control only, starter unit and wiring are not included. I think it can also be used as a smart key if you obtain a mechanical key at the dealer and set it up. Operation cannot be confirmed at present, so please understand. Since the antenna part is missing, this is a junk item. Please purchase only if you understand.
