Here’s a function which grabs the field key from registered field groups given a name (note it returns the first key found, so it won’t work with multiple fields with the same name):

function get_acf_field_key($name) {
    if( !empty($GLOBALS['acf_register_field_group']) ) {
        foreach( $GLOBALS['acf_register_field_group'] as $acf ) {
            foreach($acf['fields'] as $field) :
                if ( $name === $field['name'] ) {
                    return $field['key'];
                }
            endforeach;
        }
    }
}
