Based on both the fob and the dashboard trunk button failing (if it were the fob battery, the dashboard trunk button would be unaffected), and the intermittent nature of the problem, my brother (former auto mechanic) suspects the problem is in the electronics that handle the electric door locks and the electric trunk release.
His theory is that solder traces/joints in the electronics are developing cracks.
The car is 7 years old, daily driver. Things break over time.
