I once lost my only key for a bike. After several calls I found a couple of locksmiths that claimed they would be able to make a new one from the ignition. I was quoted 75 if I brought it to them and 125 if they came out. So, I took it out and as I made my way to lock the door before I left.........There's the damn key hiding in the grass !!!!

Kinda pricey, but if you need it........
