Still wondering what made you think a magnet would affect an EPROM
(or is it EEPROM?) like that in any way. Maybe you're just used to
dealing with magnetic storage media?

Now, if you took the thing with you into a MRI machine, I guess all
bets would be off, but otherwise ...

It's a specif type of EEPROM than can be addressed (read/write) by
blocks. The old EEPROM had to be erased all at once then reprogrammed.
Like the BIOS in a PC. When you update it, the addressable part is
completely erased and then written with fresh data even though it's
just adding some features and replacing some buggy code.

But you are correct. It would take a lot of EMI energy to corrupt data
on a EEPROM.

Yep I would consider that a substantial amount more EMI/RFI than a mere
magnetic cap on a modern flash FOB.
