I did the same many decades past. Trouble is I stopped reading after the first 40-50 pages. Drove off home feeling quite righteous and.....
Turned of the ignition and pulled the key out. Well attempted to and failed. This was before mobile phones became ubiquitous.
Quickly grabbed the Toyota manual and re-read the first 75 pages (who knew there was a manual screw system in case the pop-up lights blew a fuse) but could not find anything about "ignition key sticking".
So the dilemma -
- Did I dare get out of the car to go inside and phone leavng a brand new car with the ignition key inside.
- Sit and wait a few hours for a neighbour to come home/walk by.
- Drive back to the dealer and admit defeat.
- PANIC!
Re-read manual a few times while thinking which option to take, thought there must be a really simple explanation, surely.
Twenty minutes or so later I was down under the steering column looking up and saw the small black plastic button about half the size of a pea, sticking out around 1/16th of an inch aka 1.5mm - and pushed it. Nothing remarkable seemed to happen, so back sitting in seat pushed it again and pulled on key - miracle.
Give me COBOL, CPM, MDBS, Pascal, Fortran, BDM, even the complete set of Vax-VMS manuals (why had nobody at UNSW ever opened them?) any day.
