I have a 2002 bonneville ssei got in my car the other day & it wouldn't start all lights came on but nothing when i turned key. Got a jump & drove home fine but when i turned it off and tried starting again did the same thing replaced battery the next day & it still wouldn't start but all lights came on the security light was flashing. After looking up info on the internet decided to go out & try some of the fixes others suggested now when i go out to start it i have no lights at all, hooked battery charger up to the brand new battery & it now will not take a charge at all also can not take the shifter out of park.

i would start by cleaning and reattaching your battery cables at both ends and any other of the big cables you might have

Have someone see if the brake lights are coming on when you step on the brakes. Sounds silly, but tust me, it will rule out one possibility.
