This is a keyless entry unit with the manufacturer part number 88035AE050 designed for a 2000 Subaru Legacy Outback. It is an OEM part, indicating it is a genuine product made by Subaru for optimal performance.
Was not as advertised, NOT for a 2003 Subaru Outback.
Was advertised as fitting a 2003 subaru outback, but it had a different kind of connector and was for a different model or year. Different part number than what a 2003 subaru outback uses.
