I just called a locksmith and I've been informed that this is a very common problem with the Focus. Ford dealers even has him install the same type of ignition cylinder that will most likely seize up again even though he has mentioned to them that there is a better aftermarket one.
He said he's replaced 100's in the last few years and they keep having him install the crappy Ford replacement. He was telling me on one Focus, he's replaced the IC 4 times in the last two years.
He has an aftermarket one that is know not to seize up and is better than the one Ford uses.
It's the one he uses if customers have him replace the IC.
Also, I called 4 Locksmiths and they all know about this ignition cylinder issue.
Everyone seems surprised that there is no recall or free fix from Ford on this problem.
Anyway, I would suggest that anyone having this issue get an aftermarket one from a locksmith because getting the one from the dealer will most likely have the same issue in the future.
