Aston Villa have defended increases in ticket prices announced for next season.
"Our most expensive adult season ticket is under £27 per game," she added.
Villa have also announced that there will be no concessionary prices on matchdays or for new season ticket holders in central areas of Villa Park's Trinity Road or Doug Ellis Stands.
However, Ms Keye stressed that the club were not trying to penalise young supporters: "If there are juniors that want to sit centrally in stands, they can do that at the two ends of the stadium for less than £200.
"If they want to sit centrally on the sides and don't have an existing season ticket then that will cost £510.
"But I have to say there are very few seats available in those areas and 99% are already occupied," she added.
