It seems to be a random thing due to loose production tolerances. My keyboard battery has been working fine since the first time I rebooted the Pinephone with the keyboard installed. At this point I've removed and installed it several times and power from the keyboard battery still works (phone turns on as soon as inserted, so at least for now. The method of shimming the pogo pins as described above is probably the best option for those experiencing this problem.
