One of those small common tip screwdrivers. I had a rig sitting over at a guy's house, he was being a jerk, and wouldn't give me back the key to the truck, but yet wanted the truck out of the way.

I was ready for this; took the cylinder out of another rig of mine and brought it with. Took some work and patience, but got that thing popped out, put the other assembly in, and towed it away. Gave the guy the finger as we pulled out. <img src="/forums/images/graemlins/butwiggle.gif" alt="" /> <img src="/forums/images/graemlins/nana.gif" alt="" />

You'll need a paperclip too, to push in on the retainer button while you work it with the screwdriver.
