Can't pair apple wireless keyboard (aluminum)

I'm trying to connect and pair a new wireless keyboard to mac mini with Snow Leopard 10.6.3 and it's determined correctly as 'Apple Wireless Keyboard', but then I'm prompted to enter few numbers and hit return. I do that but it doesn't seem to work and I get "The pairing attempt was unsuccessful. Click 'Continue' to try again." Keyboard is on and blinking during that process and my magic mouse works perfectly so bluetooth itself seems to be ok. Any suggestions?

Have you tried pulling the batteries on the keyboard and letting it power back up yet and restarting the mac as well?

Have just tried that -- it didn't help.
See if Mouse Keys is turned on. It can stop your keyboard keys from registering when you do the pairing.

To check your System Preference settings, or to enable/disable Mouse Keys:

    1. Open System Preferences and click on the Universal Access preference pane.
    2. Click the Mouse & Trackpad settings tab.
    3. Click the "Off" radio button next to Mouse Keys.

I was going to suggest new batteries. Also, be sure that Caps Lock if off as well when you hot the keys.
Have you tried paring it with another machine to see if the keyboard is good?

It also looks like you are not alone:

One post I saw said to hold the return key down and at the same time select the keyboard. Not sure why that would work, but some have said it helped.

Strangely, this just happened to be on an old 12" PowerBook and a white Bluetooth keyboard. I turned off BlueTooth on the Mac, then switched off the keyboard and then back on, and the turned BlueTooth back on. That seemed to make it work once!
