I thought it would not happen to me, after all I did the sticky key fix.
Lo and behold the key was jammed in the ignition when I got home yesterday, I turned it ON, turn
ed it OFF several times, still stuck.
Knowing a little about it, I turned the key ON, moved the gear shift to drive and then turned the key back to OFF and the key came out lickerty split.
When I tried to do it it always came out, but later in the day I went out and upon returning home it stuck again. I repeated the gear change solution and out the key popped.
Some fine adjustment is called for I think.
