I do t think there is any key hole for ignition. I've had problems with my fob a lot recently. Button won't work on fob or door many times and some times it won't start car either.
When it doesn't start it asks you to place the fob on the button and then it starts. Something about touching the button with the fob starts it. Weird.
I think my battery is old perhaps. Not sure though cause I've also gotten it very wet. One time LOL
