The ignition keys that came with my project boat don't seem to work. They fit into the ignition but will not turn. I have removed the ignition switches and given them a little squirt of silicone lube and worked with themfor several minutes at a time over the past several daysbut the keys still won't turn.The switches are in good shape and I'm pretty sure at this point that the keys I have are not the right ones. I'm assuming that ignition keys for boats come in standard patterns. My question is where would I go to get the right ones and how do I tell which ones I need?
