Check the wire that comes off the battery and goes right to the firewall. Make sure the in-line fuse holder is tight. Also check the ground from the battery to the frame. I've replaced 3-4 of those wires because the crimped end came loose from the wire. If that's not your problem then it could be the new battery. It does happen from time to time especially with cheap Autozone n Walmart batteries.

It just dead, I changed the ignition switch and new battery but nothing , I will double checked what you want me to check earlier once I get off.

You changed the ignition switch? Did you have the key reprogrammed. The ground wire off of the battery is a good place to start. Check and see if the crimped end is loose on the wire not just the bolt to the frame.

I didn't change the whole set but just the switch not the lock itself. I will check the ground asap. Hate this car already . Break my bank and this is what I got. Thanks I will keep you in touch.

My 07' Tahoe is doing the same thing. Finally got it to a parts store when it wouldn't start up, It was a PO573 brake switch/cruise control error. To get it start up, I have to pump the brake twice to get it to restart. This is after a day of having the car at the dealership and them not being able to detect any problems. Now we know what the problem is,.

My daughter has a 2010 Tahoe and it had the NO POWER AT ALL issue. There is a fuse on the positive terminal that is bolted in place. I removed it and tested if for continuity, It failed. I went to auto Zone and purchased the same fuse for $5.00. It corrected the issue.
