A blind hole is one with only one opening. He suggests you just have to drive
out a couple roll pins, doesn't sound like that big a deal.
Those work almost exactly the same as the side cut key locks, take all the
little wafers out making sure you keep them in order, clean each hole with
whatever it takes, a needle file will probably help. Clean each wafer until it
shines. Reassemble with plenty of lube, I didn't find Houdini to work well for
that, I like just dry graphite but you might have to use something else if you
have an alarm.
Once you've got it all clean and reassembled if it doesn't work well you can
use a file and sandpaper to shave down the outside of the wafers to get a
perfect fit. Make sure you test with multiple keys, its easy to get a lock
working with an old key so it won't with a new one.

Found this online for a 201 car, might be "close enough". Looks like I need
to remove the two pins that are in blind holes. Oh joy.

Hmmm, that link looks ugly, maybe this will work?

FSM Procedure 72-240: Well the lock / tumbler assembly is very easy to get out
of the door: on the back edge of the door, remove cover over little hole,
insert 3mm hex and turn out (CCW) hex screw four turns. Insert key, turn to
unlock (CW) direction, push lock / tumbler toward rear of car and pull out.
Easy peasy, takes me longer to get the tools out than to pop that lock /
tumbler out.
Washed it out well with brake cleaner, then with Houdini Lock Lube, no change.
Lots of black juice ran out, I kept going until it was fairly clear, but nope.
It looks like there is a pin at the end of the assembly that can be removed,
which then allows a piece and a spring and then a cir-clip to come off, and
then just maybe the tumbler will come out of its housing. There are two more
pins inserted into blind holes, I guess I'd have to grind the housing off on
the blind side to be able to drive those out, but I'm not sure what that would
gain me unless my first guess about removing the tumbler is wrong.

I'm going to remove old tumbler, flush it out really well and lubricate, and
see if that clears the problem.
New thought; if re-key of the driver's side tumbler is not possible, perhaps I
can swap the passenger side to driver's side.
