How to Reset Car Radio After Battery Change

Turn your car on, but do not start the engine. Turn the radio off. Hold the radio power button down for a few minutes until it resets .

Have you ever replaced the battery in your car and ended up with a radio that no longer works? If you have, then you know how frustrating it can be to try to figure out how to reset it. Some people suggest taking it to the dealer, while others recommend waiting hours or even overnight for the radio to reset. The good news is that there is a simple and free solution that you can do yourself in just a few seconds.

Firstly, it’s important to note that if you’re going to pull the battery out, you need to hook up an auxiliary power source. Otherwise, you’re going to lose all your programs and pre-programmed radio stations. In some cases, the radio itself won’t work.

For instance, an 08 Dodge Ram will not work at all if the battery is pulled without an auxiliary power source. Many people suggest taking it to the dealer, which can cost you around $150 to reprogram it. Some suggest replacing the whole radio, which can cost you about $300. However, there is an easier and cheaper way to reset the car radio.

Here’s how to reset the car radio after a battery change:

1. Take your key and put it in the ignition.

2. Turn the key backward to accessory.

3. Turn on your radio and your radio will come on and read the VIN number in that mode of the vehicle it’s in.

4. Confirm that it’s in the proper vehicle it was originally installed in.

5. Do the same thing with your CD player.

It’s weird how you have to do both of these functions, but it works. It’s also important to note that you don’t need a special code number or anything. You don’t have to panic and call the dealership or try to find a code inside the glove compartment. You simply need to follow these five steps, and your radio and CD player will be back to normal.

In conclusion, resetting your car radio after a battery change is a simple process that can save you time, money, and aggravation. You don’t need to take it to the dealer, and you don’t need to wait hours or overnight for it to reset. By following the steps outlined above, you can reset your car radio and CD player in just a few seconds and enjoy your music once again.


Why is my car radio not working after battery change?
The most common reason for a car radio to stop working after the battery has gone completely dead is that the radio has an anti-theft “feature” that kicks in whenever battery power is removed. When that happens, all you have to do is enter the right car radio code, and you're back in business.
