if you have a different key try that as it may be the diode in it. then check fuse with a test light as it may be the fuse block not making good contact causing problem.

The key didn't work. I don't know where the power comes from to go to the fuse. I have no power to the fuse. Is there another fuse somewhere?

check items in right fuse box underhood. It may be the maxi fuse or ignition relay not good you can replace relay with a like relay or go to repair electrical how to test a relay on our site here. The fuse is a larger one that is 40amp see pic
