SKS key FOBs & safety recall E0E (from 2014) plus two ECUs (motor generator MG and power management)

I have a question about a 2011 Prius Model Three which had the E0E safety recall update installed in 2014.

The E0E recall involved two new software updates being installed on the following ECU components: 1) the motor generator MG and 2) power management.

Does anyone remember if they were asked by the Toyota dealer to bring in all working FOBs when the update was installed, or if issues with FOBs, which you did not take to the dealer, began after the update?

I need to dig deeper, but I still need to confirm if the power management ECU software updates are involved in any way with FOB recognition. It is not likely that a motor generator ECU has anything to do with FOBs.
