Why will your car radio and lights not shut off with keys out of ignition?

This is usually caused by a faulty ignition switch. The ignition switch is responsible for turning on and off the electrical systems in your car, including the radio and lights. If the ignition switch is faulty, it may not be able to properly turn off these systems when you remove the key from the ignition.

Another possibility is that there is a problem with the wiring in your car. If the wiring is damaged or loose, it can cause the radio and lights to stay on even when the ignition is off.

Finally, it is also possible that there is a problem with the radio or lights themselves. If the radio or lights are faulty, they may not be able to properly turn off when the ignition is off.

If you are experiencing this problem, it is important to have your car inspected by a qualified mechanic to determine the cause of the problem and have it repaired.
