need help changing device name/passkey for Bluetooth

[Xx_xBLADEx_xX]

I'm currently Using NRG EnergyROM 9/20 and before that 9/06. Anyways I can't figure out where to go to change the name of the device. My friends phone catches my device name as EnergyROM. I want to change that name to something of my own. Plus how can I setup the passkey or see what it is already? I gointo the bluetooth settings and goto the security tab and enable passkey required but it doesn't alow me to enter a passkey or change the existing one if one does exist. Thanks for any help guys.
