A good locksmith should be able to lock pick your ignition and cut a spare for you.Dun have any contact to recomend tho but look up the yellow pages and there will be plenty.Charges can on the high side but it beats having to change the ignition,the tank and probably the lockset under the seat.All this is possible provided your key are not those with embedded electronics like the Honda Integrated Ignition System. The last time I had to do this was way back in 1989.Back then,there is a locksmith that was stationed at Newton Hawker Centre carpark.Luckily that unclewas there and all he did was walk to my bike with some of his trade tools.Took out a blank key file,test,file again,test again and he was done after a few tries.Skillful I shall say but that set me back by $90.For a student,it was like daylight robbery but then all that was due to my negligence.
