Bought my 749 with only one Black key , I was always worried as Hell that I'd lose that key and be buggered. Got on to Ducati John who made a copy and did it all for £60 in one day! Blinding, cheaper than other suppliers I'd tried and bloody quick, he gives you instructions on how to test the new key before you have it cut - worked first time - excellent service, if you've only got one key John may be able to help you out.
