Ignition cylinder disassembly
Greetings, I need some help. Recently our Ford Focus had the 'classic' problem with the ignition switch.
Put the key in and it won't turn. I managed to find enough info online to successfully, and without-drilling, remove the ignition lock cylinder.

I would like to just remove the tumblers, and i have seen mehtion it doing that in numerous places, the problem in, I don't know how to even get the cylinder open.
Any help/suggestions?

its a little tricky, but i just replaced the whole cylinder.
on the back of the cylinder is a cotter pin thats almost a complete circle, remove that with a pair of needle nose pliars and the rest should literally fall apart.
let me know if this works!

Oh, Thank you SOSOSO much!! That thing WAS pretty hard to get off, but once I did, with the key out, the lock just slid right apart. It's funny, that was the piece I was looking at to begin with, then I decided I must be wrong because it won't come apart with the key in and turned to anything but off. Anyway, successful disassembly, reassembly, and reinstalation. Even did a test start of the car, and it works fine. SO again, thank you!

so if I'm right - you can (if key key can turn to Accessory position) take all the springs and tabs out and put the lock back in place an it will work? Does that mean any key will work on it and is this just a temp fix?

no problem man! send some rep points my way (*cough cough*)

glad i could help! this was such an aggravating problem with my car especially in a huge snow covered parking lot at 3am lol. that sucked.

As for the key, yeah, If you can get it to the accessory position, (I did it with a little banging after a couple tries) It can be taken out easily.

The little pin ONLY goes down when the key is in the accessory position. Once out, I opened it up, then opened the little silver colored side panel. The springs took themselves out (lol) and I took the tumblers out. I put it back together, including that cotter pin, and put it back in.

Now, as I understand, the the anti theft system is not in the ignition lock cylinder, but in the area it fits into, so replacing the cylinder idoesn't change that (getting one set to your key will make things simpler, there are several threads here about that).

Even with no tumblers, though, I have to have my 'special' key to start the engine. Any key or screw driver or pretty much anything can turn the accessory power on, but the anti theft device will not let the car start the engine unless it senses the right key.
(an added odd thing, the key now can come out, even with the car started lol)

As for how permanent the fix is, That depends. It probably isn't great it the car is a lease, or if you want to resell it, but it does not effect the running of the car, It may be a little easier to steal(it the thief maybe knew how to disable the passive anti theft thing), but then again, a thief would have no way of knowing there were no tumblers, and the wheel lock and everything still works.

GZetech, rep-points, allready done ;) TY again!

ok, let me ask this. I have a '02 SE sedan i picked up 2 weeks ago. The key works just fine however, how can i tell if this hasn't been replaced before? The key cylinder face is aluminum/chrome in color.

do a message search. There is a thread which contains photos of the old and new types so that you can identify them visually.

The following thread has pictures of old and new lock cyliders:

b16sir1991 can set you right up with a new ignition cylinder. The replacement is straightforward if you take your time.

I have the ignition out, but I just can't figure out how to take it apart. Any pictures or more specific directions? Any help is appreciated.
