Grandam won't crank, security light flashing

If your Grandam won't crank, this could be due to a number of reasons including a bad battery or starter motor. There is also another reason. If you don't hear any clicks when you try to start the car, check the indication lights above your speedometer. If the key is in the ON position and you see the security light flashing, the car thinks it is being stolen. To reset this, turn the key in the ON position and wait ten minutes. After ten minutes have elapsed, the security light will no longer flash and the car should start as normal.
