How can i connect tc to my secure network?

Question

for over a year now, i have had my tc connected just fine however today i found out that my roommate put a password on the network without telling me. now my tc won't connect and this is where i store my music and videos and printer not to mention all of my backups and large documents. i scanned with airport and it said that nothing was in range. how can i force airport to recognize my tc so that i can use the password to connect to my tc and have the ability to print and use it like i used to?
thanks,
eli

+yes, the tc was configured to join an existing wireless network, but i can't get it to connect at all or even for my computer to realize that the tc is there. now what do i do+
Your only option at this point is to reset the TC back to factory default settings and reconfigure the device. To do this,
Power down the TC for a few minutes
Hold in the reset button and while you continue to hold in the reset button, plug the power back in to the TC.
Release the reset button after 10 seconds
You almost need 3 hands to do this. It will help if you position the TC vertically on your desk with the rear facing upward.
Connect an ethernet cable from one of the LAN <-> ports on the TC to your computer. Restart the computer and open AirPort Utility to reconfigure the device. You can use the Manual Setup option if you are familiar with the settings. Otherwise, click Continue to follow the guided setup.
