Help with bluetooth keyboard

I've had my Apple bluetooth keyboard for over a year now, but two days ago I started having some problems with it.
Whenever I turn it on, the green light is on for like a second and then it's off, but nothing happens after that (it's supposed to blink a couple times before it connects). I tried changing batteries and everything I could think of, but haven't figured out a way to get it to work again.
Suggestions?

Quite possibly the Bluetooth sync on the computer may have become corrupted. If you delete the Bluetooth connection for the device and resync it, then it may work. This has happened to me a few times in the past.

Thanks, I tried that a couple times. The problem seems to be that the keyboard doesn't really turn itself on, so it can't connect at all.

Anyone?
