$hexified = "00,00,00,00,00,00,00,00,03,00,00,00,1d,00,3a,00,3a,00,1d,00".Split(',') | % { "0x$_"};
$kbLayout = 'HKLM:\System\CurrentControlSet\Control\Keyboard Layout';
$scancodeMap = Get-ItemProperty -Path $kbLayout -Name "Scancode Map" -ErrorAction Ignore

if ( -not $scancodeMap )
{
	New-ItemProperty -Path $kbLayout -Name "Scancode Map" -PropertyType Binary -Value ([byte[]]$hexified);
}
else
{
	Set-ItemProperty -LiteralPath $kbLayout -Name "Scancode Map" -Value ([byte[]]$hexified);
}

It worked, thanks.
One thing I want to say, is you can use Get-ItemProperty to check if Scancode Map exists, so it's not necesary to modify the script when running the first time

$prop = Get-ItemProperty -Path $kbLayout -Name "Scancode Map" -ErrorAction Ignore

if ( -not $prop )
{
	New-ItemProperty -Path $kbLayout -Name "Scancode Map" -PropertyType Binary -Value ([byte[]]$hexified);
}
else
{
	Set-ItemProperty -LiteralPath $kbLayout -Name "Scancode Map" -Value ([byte[]]$hexified);
}

Nice one! Thanks @Davido264
