Hello, first time poster here. I have an '02 Sub with 134k on it. My question is about the key coming out when the ingnition is in any position (acc, dc). I haven't tried to take it out when it's running for fear of screwing something up. Should I be worried about this? Thanks.

 

Most likely the key is worn out. It is possible the lock cylinder is to try a new key first. It will not damage anything if you remove it while engine is running. Unless you are driving without the key in and the ignition gets turned off the wheel will lock and you can not steer.
