If you had insurance I'd say park it where you did last time. But since
you don't I think what you want is a way to just get the thing started
and driveable. See if your mechanic can show you how to do that. You
probably have the "chipped" key and that saved it from being started.
You might Google that and find a work around. Or somebody will post how
to do it here.

You can replace the individual pieces, in general.

There are people around who will rebuild the column and swap it in
for not too much money. (Depends on your point of view, I guess)

OR you can go to a junkyard, pull a column, and either replace the
bad pieces or swap the column.  Your key/lock combo may have to
be swapped or replaced.

I rebuild these columns. Usually 145.00 labor + Parts.
Parts: Rack kit   28.00
        Housing    ??? maybe 35.00 It comes in black plastic so it has
to be paint matched.
If this is a tilt column hopefully the lower bowl didn't get busted. If
so you are most likely better off getting a used column. I think they
are around 125.00

   A junkyard column sounds good, be sure to get same year and model,
Best bet is to take a picture of harmonica plug that plugs into
under dash wiring.  With the column doing so many things * all *  the
wires must color code match.  If you buy a " Bone " column for parts
your screwing yourself out of parts you'll need if harmonica wire colors
are different, unless you only want the mechanical parts [ they swap ]
to fix damage.  Removing cylinder for re-keying is a pain you can skip
by buying column with key, have spare keys made, and test them !
