I have listed a lot of just over 150 Fatar spare keys on eBay:
http://www.ebay.co.uk/itm/-/282272199590I was about to dump the lot, but thought I'd list them and mention it here in case anyone needs them.
The starting price of £50 reflects nothing other than what I decided would compensate for the hassle of not dumping them.
If you're in Scotland you're welcome to collect.
