I replaced the battery on my 2000 GS300 and the car now starts for about 2 seconds and shuts off. The security light on the left side of the dash blinks but no other lights come on in the dash when I put the key in the ignition. The buttons on the key are not working and i don't know what to do.

I would say you have two options, You can take it to the dealer and have it disconnected, or you can go to an aftermarket car stereo/alarm store they will install an aftermarket alarm and disable your stock one at the same time, for probably about as much as the dealer would charge to just disable it.

There is obviously a draw from somewhere, and if your dealer doesn't have a mechanic who knows how to narrow it down to the circuit causing the problem, then I'd question there ability. With that said, when all else fails, you simply remove negative connection off battery first, then positive.

Look for alarm Brain box and look for wires coming out black and red going to valet switch. to turn valet on turn ignition in ON position and press-switch or flip depending on the type of switch. If it a basic alarm just disconnect the main wiring harness to alarm box- unplug and the car should start. Good luck and thanks for using FIX YA
