I am trying to remove the lock cylinder on my chevy impala. However, I
cannot get it to come out of the steering column. I have removed the
steering wheel, the locking plate, and the turn signal assembly.
However, I cannot figure out how to get the cylinder out.

The haynes manual says that I should insert the screwdriver into the
turn signal slot and break the housing flash. then depress the latch
near the end of the lock and it should slide out. I am not sure what
slot they are talking about, as the only opening in the metal, is the
opening for the top of the rod. Any help would be appreciated, as I
have no idea what it means by the housing flash.

I might be talking apples vs oranges here, but some GM locks need the
key and a pin to pull them.  You put the key in the lock and push a pin
into the small hole in the lock face.  The lock can then be removed buy
pulling on the key.  I don't remember if you had to turn the key, it's
been a long time.

Other than that, the directions you mention would almost sound like you
are removing the whole column cover, not the lock out of it???

I believe thats only on newer model locks. I am going from the haynes
manual, but I really dont want to break something.  Im not trying to
remove the column cover, just the lock cylinder and sleeve from the
column.

Here is the step that I need clarification on

3. Insert a small screwdriver into the turn signal housing slot.
Keeping the screwdriver to the right of the slot, break the housing
flash loose and depress the spring latch at the lower end of the lock
cylinder. Remove the lock cylinder.

The pin was used on some older ones.  Does the face of the lock where
the key goes in also have a small pinhole in it?  If not, my advise
doesn't work.  Maybe that was only for the in-dash keys.

The would imply to me that you have to come at it from the other side.
Do you have a turn signal slot on your column case?

I don't know what Haynes means when they call it the housing 'flash'
unless there was an aluminum pin installed to set the lock that needs to
be snapped off to get it out.

Some locks go in with a set pin or even bolt that the head gets snapped
off of.  This is a security pin that either needs to be snapped or
drilled out to remove the lock.  You will need a new pin or 'flash' to
install the new lock.

What does Haynes say about re-installing the lock?  Maybe there is a
clue there.

I also think it is a 'Saganaw' brand steering column.  Maybe the
internet has generic Saganaw directions?

I just experienced the same thing and finally had some success!!  I am
removing the lock cylinder from a damaged steering column from a '79 Scout
to swap it to a new column,(Yep!  International used GM columns too!!)  and
had a hard time.  Turns out there is a small metal tab that is spring loaded
at the inner end of the lock cylinder that sticks out when the cylinder is
removed and acts as a latch when it is installed in place.  The Scout shop
manual says to use a small knife or a machinist's rule to remove the
cylinder.  Put the lock in the "Lock" position so it wil be easier to align
with the sector gear when you re-install the lock.  You will have to push
HARD on the tab with the machinist's rule and also pull outward hard on the
cylinder.  Mine started to pull out slightly, and I pried the lock gently
with a wide bladed screwdriver.  Once started, it slid right out.  Let me
know if you need a photo of the removed cylinder, it might help you see what
you have to overcome.
