asked by on

After changing the stereo I turned off the car and tried to start it and all my warning lights came on they don't blink and the car won't start

My car has 203865 miles.
My car has an automatic transmission.

Hi there - the security system is intentionally invoked after a battery replacement. Turn the ignition key to the "On/Run" position, and leave it for 10-15 minutes in this position. The security light will go out, then you can start the car, and unlock your radio with the code.
