ANOTHER DO NOT PRESS THIS BUTTON!!!!/Pears/House

The door opens and you step inside. The walls are light orange inside. I hope it's not orange moss because my nostrils will wisper to me. Nobody is inside and the house is empty except a keypad on a wall and a desk with a phone. On the phone, several keys are darker than the others. You enter those numbers into the keypad and a door opens. Inside there are two buttons. One has a tag under it labeled "Jewel" and another is labeled "???" very faintly on a scratched tag. What do you push?

Jewel
