Humph!!! Ford Focus!!!?

Okay, I have an '01 Ford Focus. My key won't turn in the ignition. I looked at the threads posted and decided to change the cylinder myself. After taking off the casing and purchasing a new cylinder, I followed the step by step instructions to remove the cylinder. Here's the problem. I've been instructed to stick a pin or phillips screwdriver into the pinhole facing the driver. But, it also states that I have to turn my Key to ACC, then insert something into the pinhole. My question is, "How can I turn the key to ACC, if my key won't turn at all." Will the cylinder not pop out if the key isn't in the right position? My fingers are sore from fooling with this issue. Please help.
