Check for a broken door spring and remove the cover from the motor unit and check for a stripped drive gear. The gear is white nylon and it will be obvious if it is bad.

You have 3 openers that are completely different when it comes to technology. A billion code, a security + and the opener with the purple button is on a different radio frequency. There is no way to open all 3 doors with a keypad.

When I try to put the garage door down, it will travel for 1-2 seconds. then it will stop, the unit will make 10 or so "clicking" noises that sound like a car blinker, and it doesn't close.

Check the sensors in the doorway. Make sure they are pointed at one another and the small light on each one is lit and not flickering. Tweak them a bit. If you cannot get both lights to come on you have bad sensors.
