Locked out of your Hyundai stereo after a battery change? Here's exactly what to do.
If your Hyundai radio is showing a lock prompt and won't play, it has activated its anti-theft lock — usually after a dead or disconnected battery. You'll need your factory unlock code to get it working again. Here's how.
Hyundai factory radios store an anti-theft code that locks the unit after a power loss. We retrieve it from the radio's details.
Send us your Hyundai radio serial number (or VIN where applicable) and we'll look up the correct factory code and email it to you. Standard delivery is 30 minutes to 24 hours, 7 days a week; Express is guaranteed within one hour during business hours.
Enter the code with the preset buttons as shown in your instructions.
We've supplied factory car stereo unlock codes since 1998, with a money-back guarantee if we can't retrieve a working code. Thousands of Hyundai owners have used us to get their radios playing again.
