    My battery is completely drained.

    I had done the PIN iginition sequence to de-activate the fobs.

    When I try to charge the battery with a charger, the alarm goes off and I cannot shut off the siren.

    Is there any way to charge the battery without the siren going off the whole time?

    Or is there a way to reactivate the fobs while the battery is dead so I can click the fob to turn off the siren as soon as the battery is hooked up to the charger?

    Thanks...

    If the battery is completely drained, you should be able to disconnect it without incurring further fob decompuberation. Lift the negative post, charge the battery and when you put the post back on hit the siren killer switch. There's a good chance you will need a new battery so you might check out a proper source, and definitely find the reason for the drained battery.

    I did something stupid and completely drained the battery on my 360. I turned off the power switch and charged it back up with my trickle charger. Now I am only running on 1 bank. I know, turn off the power switch and reset everything. Interesting, when you turn off the power switch the trunk light stays on and it doesn't clear things. Next move is to disconnect the battery. I am confident that it will reset everything but not sure if I will end up at the shop or not. I will update after I get back from vacation and disconnect the battery.

    I've looked for a couple of hours for the location of this "siren killer switch" to no avail, including through my manual. Sorry to bother the forum for something that I would think would be obvious, and freely admit I couldn't find my head were it not . . . you know. Situation: got a newly reprogrammed fob and tried it, car did the double beep and all seemed fine. Then I immediately tried the original fob to re-arm the car and the alarm siren activated. It is an astoundingly piercing thing, I have to say. Nothing I could figure to do would deactivate the alarm short of turning battery cut-off knob to disconnect the car's main battery. Please advise. Thanks!
