Okay, so I am on the home stretch on finally getting my bike completely reassembled, though by no means done, so i can ride it in the mean time between various projects. So i have a functioning ignition, works fine, looks great, and i have 2 keys for it. now here is the problem, my gas cap latch lock decided to puke it's guts out and they went bouncing around the garage floor, and there was no lock cylinder in my seat lock. btw the bike is a 1979. is the cut of the key vital for the seat and gas locks? i really don't have the money to buy a brand new matching set of ignition and both of those locks with keys, so i was looking at some used pieces on ebay. i can get each lock pretty cheap without keys, while the prices aren't too bad to buy them with keys either. problem there is i really don't want a different key for everything. if i order the parts without keys, will my keys still work, just being cb keys with the proper shape of the shank? or is the cut of the teeth crucial? i have heard any key regardless of cut will work in the seat and gas locks, just the ignition is the picky one. but i wanted to ask and find out for sure.
