Are you sure the steering wheel does not lock?
On my manual transmission Fit the steering wheel still locks when the key is pulled. Once it is locked, putting in a key and turning to first notch unlocks it. The mechanism is subtle, compared to what they used to be. There is no interlock with the transmission, I can lock or unlock in any gear, and shift gears when the steering is locked.
The locks are mandatory equipment in many countries, so almost all cars sold globally have some sort of steering lock mechanism. Check with the dealer service department about whether or not the lock is there and working properly. Don't count on a salesman getting it right.
