Hi Kim,

You can try resetting the system by leaving it unpowered for 24 hours or more:

Go to the battery cabinet (usually located in places like the master bedroom closet), find and unplug the power transformer (generally in an outlet somewhere relatively close to the main cabinet), and disconnect the backup battery. This will completely shutdown the system.

Wait 24 hours, then power the system back up, AC power first, then reconnect the battery.

Then press # ***** it returns to normal run mode.
Once in normal run mode key in: * 8 5555
If it beeps rapidly for a few seconds and the program light comes back on, then the factory default installer code will work, and resetting your master code will be easy.
