Yes. This is frustrating. I wiggled the wires that connect to the key mechanism. That fixed it for one mowing. I used two jumper cables to connect to each of the two wires which go into the key lock mechanism (bypassing the key lock mechanism). I connect the other jumper ends to a plastic part. When I want to start the mower, I take the jumpers off the plastic and connect them to each other. It starts every time, but I haven't had to mow since I did this, so I don't know how durable this kludge will be.
When I connected the jumper, I noticed the jumper teeth scraped some clear plastic off the wires ends. I'm guessing this plastic was interfering with the electrical connection. This was probably waterproofing for the electrical connection. Seems like a good idea, that goes wrong, when the plastic shifts around.
By jamming the jumper onto the ends of the wire, I bent the connector on the ends of the wire. I'll never be able to reconnect those bent ends onto the key lock again. That probably voids my warrenty. But what good is a warrenty when I don't have any way to haul this mower to be repaired?
