These are Ironheads you can start them with a 3' piece of wire no matter which ignition switch you use.

 

My kid found it before I had to spend any time or money **whew**

 

Now that you found it, go make a couple of spares. I had my '77's key copied at a locksmith. He had the blank in stock. Cost me about 2 bucks.

 

OK, so having kids is a good thing.

Me too. First time i went years ago the 'smith was out of the correct blank, but he ordered some in.

 

Eh I got a key to keep honest folks honest, all a thief has to do is unscrew one bolt and wire the two power wires together and drive my scoot off. ( I got the dash and tanks from a Low rider.)
