I went to a locksmith and he told me to buy a Ford Aerostar ignition cylinder instead of a new focus cylinder. He said he's been gettin' at least 4-5 focii a week n that if i put in another focus ignition cylinder, it would probably fail again later on. So I bought the Aerostar cylinder as the locksmith said, had my key matched to it, n had my dad install it. Costed about $45 for the cylinder and $35 for the locksmith to match my key to the cylinder. I hope this helps anyone and prevents future ignition cylinder lock-ups. Oh yeah, my ford dealer even gave me trouble when i wanted to buy the aerostar part. What's their problem? This is the last ford i ever own!
