attatched interupt seems to trip on power up

I discovered that when I power up the system, sometimes it acts like the button was pressed on D2. It's just a push button, NO.

...in Setup()
    attachInterrupt(0, OverrideSwitch, FALLING);//TURN ON INTERUPT OF MOMENTARY PUSHBUTTON ON PIN 2
    digitalWrite(2, HIGH);             //TURN ON PULLUP FOR PUSHBUTTON ON PIN 2  

...

void OverrideSwitch(){
ButtonFlag = true; //set the trigger to activate the door
}

I've change the Interrupt call routine to this, but it seems a bit lame. It just checks to make sure a few seconds have passed since startup

    if(millis() > 5000) ButtonFlag = true; //set the trigger to activate the door

Do you have pull-up or pull-down?

MarkT:
Do you have pull-up or pull-down?

...just the line digitalWrite(2, HIGH);

Try attaching the interrupt after you enable the pull-up?

I tried this to no affect. Anyway, the 5 second delay takes care of it...
