Question Ignition Cylinder Tumbler question

I have an '03 ZTS that hasn't exhibitied the ignition cylinder lock issue yet (thankfully), so I want to replace it as soon as possible.

I looked on eBay and there are number of options.

Can someone recommend one of these or any other option over another??

Thanks

I didn't check eBay, but here's the Motorcraft one I bought in 2009 on Amazon. Haven't had a problem. Some seller's still sell the old version that eventually will get stuck. This is the updated one. Do a search with the part number form Motorcraft, then you can compare prices.

Hold cylinder just like in pic with keyslot toward you, orient it so the key in cylinder body faces down, if you simply take a dremel with a small rock and then grind a slight radius on the left edge of that key as looking at it like described. The radius allows the key to bump up and over groove edge with even a pretty good amount of wear on the guts. Sharp corner there and less lift from tumbler wear causes the problem. Both mine done like that now and no problems at all, one had locked up a very good while back. The other was a pre-emptive strike. My Contour also done since cylinder uses same design. It had trouble trying to hang too until done. Free and bulletproof.

What is the cylinder lock "issue" that you are referring too? What do I need to look out for?
Thanks!

See the key hole slot in the picture?

That is the revised cylinder not much worry there

If yours on the other hand have the key hole slot offset replace it ASAP

What happens if there is some sort of offset? Will the key not fit at some point? If so, will it give any kind of warning or will it just not go all of a sudden?

The ignition cylinder with offset is the old version that will eventually lock up on you.
What are you going to do if it locks up in an airport ramp, drug infested, violence infested part of town or in the middle of nowhere?

What you have is a ticking time bomb
FAR better to go to Ford garage tomorrow morning and get that replaced

Just buy it from Ford. They are only about $100 or so and that is with the tumblers set to your vin. number. Then do the install yourself. It only takes around 15 mins to do.

You stick the key in one day and suddenly the cylinder does not turn. Key however goes in fine. Lots of time no warning at all. When it happened to me at 2:00 in the morning I spent the next 45 minutes until by luck it finally worked once to let me get home.

When key goes in, the lined up tumblers then lift a key out of a groove, when they wear the lift decreases. At some point the lift is not enough to clear the key from the slot, a very sharp corner there makes it pretty much show up at once with no warning.

The slight bevel on edge I mentioned allows even a worn tumbler for less lift key to bump up over the groove edge.

Takes like 30 seconds to do it. Of course cylinder must be out of hole. I do not have the revised cylinder in any of mine.

You could always just remove the tumblers altogether
