dashboard completely dead drove out anyway like 15 miles with dashboard black everything was off than when I stopped at auto repair was no one available so I took off while driving dashboard came back on and said 3 keys were added what does that mean why did it do that was it hacked?
I recommend taking it to a dealer. I’m not a mechanic or a Cadillac owner so I can’t speculate.

No, it wasn’t hacked.
The dash has a fault and may need to be repaired or replaced. Likely you’ll need a specialty repair shop as I’ll be you can no longer get a dash from Cadillac.

Crutchrields is a good plce to start.
Would that also explain why the dash indicated 3 keys had been added?
Possibly. Electronic failures can often give strange symptoms.

But, this also makes me wonder if the OP’s alternator is not working optimally and is about to fail.
