It happened near 83rd Avenue and Lower Buckeye Road.
Police say a young mother accidentally locked her keys in the car while her baby was still inside.
Anthony Garcia was working in the area when he noticed people gathering around a car in the parking lot.
He says the mom was panicking and that is when he stepped in.
"I wrapped my shirt around my hand, and I just grabbed a crowbar, and I smacked the window two times and it broke, and I opened the door and got the baby out," said Anthony Garcia.
Garcia says the baby was sweaty and crying, but otherwise okay.
Firefighters arrived moments later.
