I need HELP fast
Check the voltage at the battery. Then check the voltage at the under hood terminals. If you don't have at least 12.7 at both, then charge the battery. If you get 2 different readings, then look for a bad connection.
While your in the back, check the fuse by the battery.

Does the radio work? That's part of the anti-theft system. Did you accidentally break a wire? Did you accidentally disconnect a wire?
If you are lucky you just blew one of the large fuses or relays. Check everything with a VOM, not by sight. If a fusible link or diode got fried, well, troubleshooting time is expensive. You may have shorted a cell or 2 in the battery. May have fried any one of the digital modules. May have fried the PASS-KEY III+ transponder.
I think that the anti-theft will let you drive for a couple of minutes before it does anything.
As I stated "THERE IS NO NEGATIVE POST ON THE FUSE BOX". It is grounded to the frame.

It is an '06, way out of warranty. How do u check the relays, diodes? The radio does work, everything works, but when you turn the key display lights come on but no clicking, nothing like the car is going to start.
Unfortunately it sounds like you have a "cascade" type failure on your hands, one thing triggers another etc.
If you know a tech with an electrical background, its time to enlist their help. Unless you have access to a VOM, and the patience to check everything in the circuits with regards to continuity, its time to call in the cavalry.
Its all too easy to "spike" a module with either excessive current, or a momentary polarity reversal, a fried BCM is one possible cause of your issues.
But you also need to eliminate the "well it can't be that surely" things like a bad starter.
Relays can be checked off the vehicle for continuity and function by using a test light with the ability to also feed 12v to them, your local parts store will have them along with VOM's.
