There are 3 levels of lockout, in order here from simplest to most complex.

1) Front Panel Button Lockout  To lock/unlock, press the PREV and NEXT buttons on the faceplate at the same time (XTi, CDi, DSi, iTech).
2) Software Lockout  Use System Architect to communicate with the amp.  Open the ampís control panel and check/uncheck the FRONT PANEL LOCKOUT checkbox.
3) Password Lockout  If the amp shows up in System Architect with a small padlock icon on it, the only way to defeat this password lockout is to reflash firmware.  

XTi/CDi/DSi:    Use CLoader.exe (available here as an attachment) to manually load firmware.

All other amps:   Install iQwic and use its TCPIQ Utility  (available at crownaudio.com)to manually upload firmware.  Ignore any messages that say ďNo OIF fileĒ.  Firmware version must be post-2.0 in order for System Architect to see the amplifier after this step.
