My car has 12000 miles.
My car has an automatic transmission.

Hi. To reset the security system after replacing the battery, perform the following process: 1. Turn the ignition key to the "ON" position (but do not start the car), leave in the "On" position for 11 minutes. 2. Turn the ignition key to the "Off" position for 10 seconds. 3. Repeat this process 3 times. This should reset the Security light/system and allow you to start your car.

If you are still having problems getting the security light addressed, you may need to have the dealer reprogram the system so that it no longer causes trouble.
