My 2008 trailblazer won't start
 

Hubby went out to hook up the battery charger and it reads a full charge....it's also a brand new battery. Plus when I had went out to start it it wouldn't give me my keys back!😮. They are stuck in the ignition.

Turning the steering wheel back and forth while pulling the key out will sometimes do the trick. Jiggle the key while pulling it out. Need more information about the starting problem.
