My car has 159 miles.
My car has an automatic transmission.

Hello - replacing the ignition switch (equipped with anti-theft) requires a Honda software scan/reset tool to sync the new switch with the rest of the anti-theft system. A Honda service center (dealer or independent) with this tool will be required to do this.
