OP, I think Envy* is right. I know Warwick do that, as my brother had his flatmate's keys left with him. I'm not sure if Aston do it, but if you ring them up, they should be able to sort it, as it's only one person, not loads. That said, I cracked up at the irony of the situation, when there's an ad at the top of the page saying 'Aston students are better prepared'
