Yes, there was certainly a chip back in the '90s (it might have been
called Viper) where every combination had been thoroughly tested and
it was known that there were no hardware design faults. I'm sure such
chips must exist today and, if so, the simple code required for
something like a remote should also be able to be exhaustively tested
(automated testing) and provide a system that cannot fault or lock up
- ignoring hardware failure.

But a remote is a battery operated device and electronics have a limit
to how low a power supply can go.

And brownout protection simply stops them until you replace the battery.


But batterieswhen left often have a habit of "recovering" for a short
period.
