Key Reset / Computer Reset

I was attempting to reset the brake fluid change service indicator light and apparently messed up the computer.

The car want into some sort of check mode - all the gauges cycled to max, the hazard lights flashed and the display got bright.

The car now barly runs. It idles rough. Any help on what to do next is desperately needed.

Let it sit and tried it. Car ran rough for a few minutes then seemed to learn. Running fine now. Was going to try my spare key and discovered it is lost. Searching all over - may need to get a replacement.
