I couldn't get the lock cylinder to come out of mine. I tried WD 40 and any manner of other tricks in tapping it out. I didn't have the kind of power tools that were suggested in getting it out. I believe I'd read somewhere that WD-40 might work short term but would be a long-term bad idea. So I did the best thing I could think of, which was get my dealership to get it out for me. I at least came in with the parts that they needed to fix it, but I had to pay the full labor costs. I wasn't even allowed to watch them fix it, which is really what I'd've liked to see.
Oh well.
