I have a 2003 Chevy Malibu and the igntion cylinder fell out when I was starting it. I was able to get it back in, but if I accidentally pull on the key when the starter is engaged (turning the key past the "on" position) it will fall out super easily. I ordered a new ignition cylinder on Amazon knowing that I would have a different key for the ignition and doors but I noticed the small pin that was causing the problems. 
I tried to pull the new pin out to transfer it but I can't seem to get it out. Is there a way to do this? Could I get a replacement part so I don't have to replace the whole cylinder?
