Hi guys. I think the reasoning is backwards. If the security system is activated, jump-starting isn't going to change anything. It needs a jump-start because something drained the battery overnight. The same thing would happen if you disconnect the battery and reconnect it. The security system will be activated, you unlock either front door with the key, then start it up like normal.
I have a '93 Dynasty that I only drive once every other year or so and each time I plug in the smaller positive cable, the lights are flashing, I unlock the door, hop in and drive away.
I think a load test on the battery is the right approach. If it's good and not too old, disconnect the negative cable when you park it for the night. If it will crank the engine in the morning after reconnecting it and unlocking the door, suspect a drain from something that isn't turning off. If it still needs a jump-start, you know it can't be a drain if it was disconnected so it has to be a defective battery.
