G'Day Rod, yeah it happened to me in my 02 STS. And caused great mirth amongst the neighbours when the story got out.. We found that most earlier Deere tractor keys fit and work, but not our 9200. I think I must have inadvertantly turned the barrel back as i removed the key after unlocking it, so it opened from the inside, but not outside. You can read about my embarrasment in the latest Australian Grain magazine if you like. Ham in SA
