let my car standing for 3 month battery charged wont start ?how do i reset the immobiliser 2000 LS400?

disconnect negative battery cable for a few hours

immobilizer should not care how long your car has been sitting unused - it just cares that you have the correct Lexus key for your car, and that your ECU has not been swapped (theft related stuff)

Where is the immobilizer in a 2000 ls?

I thought it would be right on the key cylinder but I don't see it.

Do I need to remove the radio to get to it?

the immobilizer is really a 3 part system, consisting of the ECU (ECM) and the Transponder Key Coil which is located surrounding the ignition key cylinder area and the Transponder Key Amplifier, which is located behind the radio.

this isn't an immobilizer issue at all, the immobilizer on '98-00 cars isn't a starter kill, it's an EFI kill. The car would crank forever but never fire.

Thanks lscowboy.
I'm going to try and finish my remote start today.

I need to tap into the code wires.

Supposedly there is a yellow keysence wire. Is that on the amp?
