Wireless keyboard won't turn on after changing battery

This is what happened:

I got a message yesterday telling me that the battery for my wireless keyboard was low and I should replace them. This morning, before I switched on my Mac, I put in new battery for the wireless keyboard. Then I switched on my Mac. And I got a message on the screen saying that There's no keyboard connected and couldn't find any keyboards. I thought that maybe I need to turn on the keyboard to make it work. So I pressed the power button and noticed that the green light doesn't even come up..

What's going on? Is my wireless keyboard already dead??

Any advice would be appreciate it. Thanks.

G5, Mac OS X (10.5.2)

Take all Batteries Out.
Roll up a small piece of Tin Foil about the size of a Pea.
Drop the Tin Foil Ball down the Battery Compartment.
Put your Batteries Back In.
You should have a Working Keyboard.
This worked for several people on here including me.
I'm still running 2 months later with my rolled up piece of Tin Foil in my Battery Compartment.
I know it sounds Crazy. That's what I first thought.
Apparently Apple did not make the + Terminal Inside the Keyboard correctly.
Try it. What have you got to lose?

I used a small staple, folded into a square shape, and it worked!

Foil worked for me. Have the first version of the bluetooth keyboard and was frustrated that the $70 keyboard was busted. Thank you for submitting this fix!!!
