Why the radio asks for a code after a battery change

What to do now

1. Look for the code card in the owner’s wallet or service book.
2. Find the serial number – see how to find your radio serial.
3. Get the code from the calculator for your brand.
4. Enter it once, carefully – see how to enter a radio code.

Avoid it next time

• Use a memory saver when changing the battery.
• Write the code in the owner’s manual or keep a photo of the radio label on your phone.
• Tell the garage the code (or where to find it) when you leave the car for battery or electrical work.
