So when you try to start it the security light is flashing correct?
Here is a guide to help you reset the system:
Try to leave the battery disconnected overnight, if that doesn't work you can try a hard reboot which is done by removing the negative side of the battery, with the cable loose from the negative side of the battery, hold it to the positive terminal for 1 minute this will discharge the memory capacitors in the BCM and PCM allowing the system to reboot. Please let us know what happens.
