What is the best way to replace the Chrysler Pacifica key fob battery?

I had this one time in Michigan, my Chrysler Pacifica’s key fob was dead. Figured it was just the battery, so I popped it open with a knife, like I’m in a high-stakes heist. Found the battery—real tiny thing! Pop it out, slide in a new one (from the dollar store, natch), and boom, cruising again in no time. Simple fix, and home free!
