Default The car is stage 3 and as far as I know the ECU has no "kill" mode

The battery is not dead either.

I'm thinking it's either the alarm, the clutch pedal sensor, or the ECU is fried.

Default here you go

APR has taken your cruise control buttons and utilized them for this function. Your cruise control will continue to function as normal, but will give you the ability to scroll through the programs you have purchased on your APR chipped ECU. The procedure is simple and involves only two steps.

Step 1: Press and hold the "set" button on your cruise control. After approximately five seconds, the "check engine" light on your dash will begin to blink once per second. This will tell you that you are activating program one. This blinking sequence will continue for approximately five seconds.

After this five second interval, the "check engine" light will begin blinking twice per second. This will indicate that you have activated the second program. This process is continued to access any remaining programs you may have purchased. (three blinks = program three, four blinks = program four).

Step 2: Once you have activated the desired program, simply release the "set" button. The "check engine" light will go off, and you will be locked in that program until you change it.

It's that simple.

From what I've read, if you disconnect the battery it defaults to kill mode as a feature...

Default When you disconnect the battery it goes into "Security Lockout" not the "Anti-Theft" (kill) mode.

It also defaults to Slot 1. So when you reconnect the battery, you can start the car without a problem, but if you want to change what slot the ECU is in, you'll have to unlock the "security lockout" with your code with the cruise control stalk.

Dats how it works. :-)
