Can't Get KeyLock Assy Off!!

I've been working on my daughter's '94 Geo Metro, and I'm trying to take the ignition keylock assembly off so I can then try and dissassemble the key end of it to (yes, I know it's hard to believe) get a broken off key out of the thing. I've gotten everything I can see to get off the thing, but still the assy is not coming off...http://adageis.com/Misc/Geo/keyswitch-1.jpgInitially, I thought the strap across the top had a couple of screws holding the strap on there, but now that I've gotten all the other crud out of the way, it appears not to be the case...http://adageis.com/Misc/Geo/keyswitch-2.jpgThere is a little bit of movement when the assy is yanked on a bit, but it seems like the entire thing has a pin or something keeping it in place on the steering column. I've been wondering if there isn't something in the middle-underneath (in 1st pic) under a press-fit plug maybe?

Anybody got any ideas for this thing?

Thanks,

The Key will HAVE to be in it to remove the cylinder, if you broke part of the key off in it, you can have your local locksmith remove the broken piece that is still lodged in the lock or if you haven'nt already made the piece go futher into the lock, you may try to put the key back into it and turn to the on position, there is a poke hole on the side that you'll have to press to remove the cylinder, if you lose any of these wafers, your key may not work. so handle this with extreme care. Your key also works the doors and trunk locks on this model. They are prone to wear in the ignition lock and if the key has lots of use from it, most times it will break if its turn just right.

If you're trying to REMOVE the complete unit, there are two shear bolts at the top of the lock flange, there is a steering lock bolt that extends into the steering shaft with this style lock, but it should be no problem after you remove the shear bolts with a dremel cutoff tool, you'll have to buy a complete lock assy if you cut the shear bolts off completely, cut a streight groove into the bolts to accept a screwdriver head, and remove by unscrewing the bolts/nut head. It would be simplier to have your local locksmith to remove the broken key so you can continue to use the lock, but its your choice in what you need to do at this point.

Thanks for the comments -- I'm being very cautious as to how I proceed, as I'm sure a new assy isn't cheap! I'm going to explore the Locksmith extraction as my first choice. We'll see how it goes.

Thanks again...

Hopefully he/she was able to extract the broken key, I have done lots of these, including this style lock, so if he/she got it out, they should be able to make you a key with the broken one, or get the code from the lock, or if its been changed, to decode the lock for the complete key, so it would work the doors and the hatch. Should'nt have to cost you much to have the key extracted and a new key....cheaper than a new lock assy.
