Its not just the alarm system, the computers are still powered up.
You can get a clamp on meter and measure the drain and it can be several
watts without lights or alarm.

One even more obvious thing. The remote lock/unlock. Requires an always
powered receiver. The radio often also has a memory which is lost with no
power.

These days, why do radios still lose their memory when the power goes off.
Non-volatile flash memory is so cheap that you'd think devices would be
designed to use it for things like preset station memories. Obviously if
the radio has an anti-theft code, loss of power still needs to trigger a
challenge for that, so the radio is useless unless the thief discovers the
code.

That’s the way mine, the one that came with the Getz, does it.
Nothing gets lost, but you do have to enter the code to be able
to use the radio/player again as an antitheft protection.
