2008 trailblazer remote start, dead battery

Thanks kgerry, i haven't either on any other GM except when i've used the 1700G.

brhaugen- He hasn't brought it back since we told him to stop leaving the keys in the ignition, so I haven't measured the draw on the battery while the keys are still in the ignition which (in my theory) is activating something in the 1700G.

cntrylvr79- since he has an attatched garage to his house, he'd leave the keys in it while inside, hence battery dead overnight.  But it never died on him at work, due to having the vehicle outside and the need for the remote start.

I'll cut the wire out of the trailblazer next time he's in town and all will be well.

Sorry, Let me clarify two things;

1. I know that leaving the keys in a vehicle traditionally doesn't kill a battery either, hence the 1700G keysense wire theory.

2. When he's at work, he takes his keys inside since he'd want to use the remote start when he's done.
