Attempted (multiple times) to program 2 new key fob sensors to group 1. Using panel keypad, went to 'programming', 'learn sensor', received screen message 'trip sensor 7(blinking). Holding the new key fob I pressed (at the same time) the top key fob buttons for at least 2 seconds, the fob red light appears. I expected the panel to 'read' the key fob sensor with an 'beep' and no 'beep' occurs. They fob us unable to activate the panel. Help!
