Eventually we guessed the automatic transmission might not be set in Park, so Ich fiddled with it and got her key out, and everybody was just happy to get out of the heat.
Speaking of heat and stuck keys...
The CRV was overheating (replaced thermostat myself...not it!), so I was on my way to the repair shop when I came to a red light. No problem; I'll just put it in neutral and turn off the motor while I wait, like I'd done a couple of other times. Light turns green, battery dies (!), won't go into park, can't remove key, AAA card and cell phone at home. Brilliant.
Luckily, a couple of repo-men happened by and showed me the column mounted access panel where the transmission release button was hiding (not the convenient key slot you see on floor shifters). A jump start got me to the shop, where they kindly relieved me of many hundreds of dollars for a new radiator. Meh...the OEM unit lasted 11 years and nearly 194,000 miles.
