The problem is likely related to the anti-theft. With this being a 2009, the CAN bus needs scanned to determine if there are specific diagnostic trouble codes. Otherwise, it becomes a guessing game.
CAN stands for controller area network. Basically, all modules and computers are connected via a few wires. By scanning it this way, it will retrieve codes from all modules if a problem exists.
Here is a quick video showing how it's done:
Honestly, this is what needs to be done first. If it's possible, have that done, and let me know what codes are found.
