lockcylinder help, I'm stuck

[CutlassKid85]

Alright the the lock cylinder stuck on my truck and I ended up snapping the key off in it.

I already got the wheel and lock ring off but now I'm lost. I can't get the cylinder out. I did a search and found this:

it is different for different years:
73-78 has a section of metal that has to be broken out (if the cylinder is still OEM) its a small rectangle, about 1/16" wide by about 3/8" tall, at the "back" of the cylinder with that gone, you depress a locking tab on the cylinder and pull it out

but I don't know what part to break out, can some one point it out to me. My truck is a 77 K5 Blazer non-tilt

Well, since Im quoted, I should help you out:

In pic #2, its the recessed section at about the 1'oclock position, just before you hit the screw hole for the turn signal switch. Knock out that 1/16" x 3/8" rectangle with a screw driver and a hammer.

However: First see if there is a tab sticking down into the hole at the 2'oclock position first, if there is, push it up and pull out on the lock cylinder, that is how most are held in. If no movement, you get to break out that section.

Make sure whatever lock cylinder you get to replace it has a large tab at the very back to lock it down, not just the piddley little one accessed thru hole at 2oclock, otherwise it wont stay in your column! (I believe the one I bought for my 73 had said large tab, and the one I bought for my 78 didnt - both ordered via Chevyduty)

alright still stuck. I checked it for the tab, knocked that little section out, and I'm not seeing anything to depress. any other methods to getting this sucker out?

DUDE!!!
Call a locksmith, they have a pig tail looking tool that threads in AROUND the broken key and pulls it right out.
No need to go tearing your column apart.

 

[mechted]

is it rotated in the housing, or at the off position?
that above method should work either way... hmmm i dunno maybe its time to break down and call the locksmith.

Finally just got it out with the help of my mechanic friend. We were working on the part for the last 1/2 hour.

big thanks to you guys for the help

Sorry to dig up an old thread, but I am having troubles removing the ignition on my 77 blazer. I knocked out the slot section of metal and I also looked around in the other opening and I can not feel or see and type of release. I lost my keys so I am hoping I do not need to have the cyl turned. I marked up cutlasskid's photo to show what I tried.

Thanks guys.

Uhm, at the risk of sounding like a know it all asshat. Do you have access to a drill? If so, just drill straight down the key hole with a 3/8's or larger bit, when you get to the bottom of the cylinder stop do not drill through to outside (bottomside) of the cyllinder. At this point things should start falling out of the cylinder.
Do not be afraid of your hammer and chisel, I've never had one of these kick my ass. iff you see the snap rig looking thing that holds in the cylinder in try moving it with a small screwdriver...
