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.

So the remote crashes, reboots when the voltage is high enough and
either works for a bit or dies when you try and use it. The batteries
are dead anyway, so you've lost nothing.
