Reset is not made with Alt Amiga, it's Ctrl - Left Amiga and Right Amiga at the same time.
But you need to tell us more about what is happening.
Do you have the kickstart screen?
Can you boot from any floppy?
About the keyboard, does the caps lock lit?
Anyway, if needed, Amigakit has brand new white 1200 keyboards, even with some non US/UK layout (i am very happy to buy a brand new french keyboard lately).
