First Imac (early 09) boot with wireless Keyboard

Hello y'all. I just received my First Refurb Imac. I Powered up with my USB Wireless Mouse and Apple Wireless Keyboard. I got through the initial setup until it asked to Connect to WIFI. It asked for my Password. I then realized that My Bluetooth Keyboard was not Connected. I couldn't find any options to proceed to an option to connect it. Any advice before I go Buy A Cheep Wired Keyboard soon?

Just to clarify, you purchased a iMac that was purchased as a Refurb from someone else? You cannot purchase a refurb today any iMac that is more than 2 years old. Anyway, that machine originally shipped with OS X Leopard and a wired Apple Keyboard. While it does have Bluetooth, it was likely not configured to be enabled during initial setup since it came with a wired keyboard.

I have a late 2009 iMac that came with the wireless keyboard and the keyboard is active shortly after the iMac boots.

You should grab a wired keyboard and get into the system and then enable the Bluetooth support to connect the wireless keyboard.
