Differently-key ignition in B3?

[Doug Johnson]

I've got a B3 coupe that requires a different key for the ignition than for
all of the door locks and the hatch lock.

Can the ignition lock be re-keyed?
If not, can I do anything short of keying the other locks to end up with one
key for the car?

If you've got a spare ignition switch lying around, I'm interested in seeing
if it matches my door lock cylinders....

TIA,
