NEED HELP QUICK....THEFT PROBLEM

Try disconnecting the battery again, this time press the brake pedal several times to drain the capacitors and let it sit for about twenty minutes. Then when you try to start it again, use your extra key (hopefully you have one). Mine did this about a couple of months ago and this is what worked for me. If that doesn't work, you will likely have to have it towed to the dealer to have it checked.
 
Flatbed is the safest way and if you look in your owner's manual it is the only approved method. Other types of tow trucks can easily damage your car. Most likely damage would be body damage but driveline damage is also possible.
