Dead battery? Get your factory radio working again

You replaced your battery (or jump-started the car), and now the radio won't play — it's showing a code prompt. This is the single most common reason factory radios lock, and it's completely fixable.

Why it happens

When the battery dies or is disconnected, the radio loses power and its anti-theft lock engages. It's a security feature, not a fault. The radio will work normally again once the correct unlock code is entered.

Step by step

1. Confirm it's locked. The display will read CODE, LOC, SAFE, or similar.
2. Get your radio's serial number or VIN. See our guide on finding your serial number.
3. Order your code. Choose your vehicle brand, enter your details, and pay securely.
4. Enter the code. We email it to you with instructions; see how to enter your code.

How fast?

Standard service delivers your code in 30 minutes to 24 hours, 7 days a week. Express service is guaranteed within one hour during business hours — for when you need the radio back today.
