Just to be clear, your locks do not work with the physical key, with the remote entry, or from inside using the door switches.

The alarm does not arm or sound.

The interior lights do not come on when you open a door nor do they come on when you press one of the buttons.

Is that correct?

Check #22 "Dome" 10Amp in the engine fuse box.

Default I don't think what you are looking for is in the kick panel fuse box.

This is a diagram of the kick panel fuse box. The useful fuses are mostly under the hood.

That 30A door fuse at the bottom toward the right might be worth checking.

Mine was a fuse... Invest in a cheap test light and verify that the fuses under the hood and inside the car is good.

The lock and trunk work with the key. the remote entry does not work. The interior light and vanity lights in the visors do not work. the door lock switches do not work nor does the clock or the door ajar notification in the speedometer is not working.

Thank you all for your help. It was the 10A fuse. 10A controls all of the interior light, the power locks. tilt steering and the remote entry. My new problem is that once the fuse is installed the door ajar chime keeps ringing and the dome light stays on.. So now I need to find out which door is not closing properly,

Did you ever figure out the problem? I've came across a similar issue to when I take the key out the chime still goes on and the dome light (when in door mode) continues to stay on.

I've went through multiple threads discussing this issue and none actually lead to a diagnosis or fix. If anyone else who is reading this don't mind pitching in on what they believe it might be, that would be really helpful.
