My thought process is to get fermentation started, then once the first two days of fermentation has completed. Filling a cooler with ice and water. Then submerge the little Brown Keg (Mr Beer Keg). To keep it at the Lagering temperatures. Any more advice is very appreciated.

I have the impression you're going to ferment it at room temperature, is this correct? Is your temperature in the 7-13 C range? If its higher you might get bad fermentation byproducts. My advice: If possible, get yourself a spare fridge and a temperature controller.– rondonctbaCommented Jul 12, 2017 at 4:37

1I had an Ozzie friend place his brew bin in front of the air con unit. It definitely kept it cooler than most other places in his house– GrainMotherCommented Jul 21, 2017 at 14:50

I believe the Mr. Beer is a 1 gallon size and fits in most fridges nice. However most fridges work between 35-45°. Your target range for lagering is 48-54°F.
With out electronic temp control, you will literally need to babysit the fermentation. But you may be able to pull it off with a simple temp strip on the fermentor. By placing it in and out of the fridge every few hours, but don't let it warm up past 58°. Getting too cold really won't harm the beer, it will just slow down the fermentation.
It's a lot of work for so little beer. I would suggest sticking to ales until you expand your homebrewing more. Usually lagering is one of the last styles homebrewers perfect, because of the need for critical temp control.
