Lock your car door with the key.
Wait a minute.
Unlock you car door with the key.
Then insert the key in the ignition.
Wait 2 seconds.
Turn the key.

Observe the security light throughout that process and record what it does for each step.

It appears that you are not getting past either the security system or the clutch / neutral safety switch.

That would explain why you are not getting anything even with a new battery.

Also observe the voltage needle.
See if it deflects when the key is turned.
I am betting there is no movement as you are not getting past one or both of the above steps.

Your fob sounds as if it needs a battery.
It is possible that something is out of synch with the security system, if you are never seeing the security light either flashing or on.

Also try another ignition key if you have one, and or clean your key with windex, both the pellet and the key itself.

Let us know your results.

If all of this works properly, then we can move on from there.
