My key fob is stuck in the ignition and car won't start..any trick to remove?

Just happened to me for first time in 2010 Mini Cooper and have a tow truck on the way. I was able to get the fob out by putting the hook end of a coat hanger under the fob, which lifts the fob up over the two hooks, but the car still doesn't recognize any commands from it, so looks like I've got to wait for the tow anyway.

This happened to me with my 2007 Volvo S8 V8 when I was replacing the battery. The immobilizer was activated during the replacement (likely by accessing the interior to manually lock the car) & when I inserted the key to start the car, nothing happened & it kept the key. I went to the Volvo dealer for help and was advised to do a factory reset - disconnect both +ve & -ve leads from the battery and tie them together for 5 min. Reconnect & start. It worked. Note that just disconnecting & reconnecting one lead from the battery after the key was stuck did not work (I tried that before going to the dealer).
