Connecting Logitech Keyboard

Go Here: Connect a Bluetooth Device with your Mac

Use the MacBook Pro's builtin Bluetooth adapter (Not the USB Bluetooth receiver), You would only need to connect it once with the MacBook Pro. When you no longer need to use it, just delete it from the list of devices. Sometimes, you might need to reset the SMC.
