a bit dear at £50 delivered, but they were the only site I found still offering delivery outside the EU. The only other thing would be to see if you could buy one in person when you are in the EU.
Great work Abercol
They are more expensive than a Radar key, 25 euro for the key itself I believe. I would be happy to pay the £50 for the piece of mind and ability to plan ahead. Nice memento too.
