I take it you don't have owners manual ? I am not familiar with Toyota specifically but many cars have a switch, usually in the trunk, that is meant to turn off in the event of an accident. I wouldn't blame the problem on the switch until a little more diagnostics.
Give some more info., if possible, about the events before it wouldn't start. Was it running and quit, was it turned off and wouldn't restart or what.??

car won't start..trying to find out if it's the switch but don't know where it is.
I meant the safety switch..sorry forgot to add safety..and don't be mean..people come here to ask for help not criticism!

To the left....

behind the key

The ignition switch? If you can't find that, no wonder it won't start?!
