Unlocking a factory GM radio can be a daunting task, especially if you’ve never done it before. But with the right instructions, it’s actually quite simple. In this article, we’ll walk you through the step-by-step process of how to unlock a factory GM radio. We’ll also provide some tips and troubleshooting advice to help you along the way.
Before you begin, it’s important to gather your materials. You will need a security code, which can be obtained from your GM dealer or by calling GM customer service. You will also need a scan tool, which can be purchased online or at your local auto parts store. Finally, you will need a USB drive or CD-ROM to store the unlock code.
Once you have your materials, you can begin the unlocking process. First, insert the security code into the scan tool. Then, connect the scan tool to the GM radio. The scan tool will read the radio’s serial number and VIN. Once it has this information, it will generate an unlock code. Write down the unlock code on a piece of paper or store it on a USB drive or CD-ROM.
Identifying the Lock Code
Understanding the Purpose of the Lock Code
A factory-locked GM radio is designed as an anti-theft measure to prevent unauthorized use of the radio. To unlock it, you will need to obtain a unique code, known as the lock code. This code is a combination of numbers and/or letters that is specific to your radio and vehicle.
Locating the Radio Label
To find the lock code, you need to locate the radio label. This label is usually affixed to the top or side of the radio. On older GM vehicles, the label may be located in the glove compartment or on a door panel.
Deciphering the Radio Label
The radio label will contain various pieces of information, including the radio’s serial number and the lock code. The lock code is typically identified as "Security Code," "TheftLock Code," or "Radio Code." It may be a combination of numbers and letters.
Using the Lock Code
Once you have identified the lock code, you can unlock the radio. To do this, follow the specific instructions for your GM vehicle model. Usually, you will need to enter the code using the radio’s controls or a combination of buttons and the power switch.

Identifying the Vehicle’s VIN Number
The Vehicle Identification Number (VIN) is a unique 17-character code assigned to each vehicle. It contains valuable information about the vehicle’s make, model, year, and assembly plant. To unlock your factory GM radio, you will need to locate this number.
Here are six methods to find your VIN:
1. Driver’s Side Dashboard
Look for a metal plate with the VIN etched into it, located on the lower left corner of the dashboard, visible through the windshield.
2. Front of the Vehicle
Open the hood and locate the firewall, which separates the engine compartment from the passenger compartment. The VIN is often found on a metal plate attached to the firewall, near the driver’s side.
3. Door Jamb
Open the driver’s side door and look at the door jamb (the part of the door that fits into the body of the vehicle). The VIN is typically located on a sticker or metal plate.
4. Vehicle Registration Card
Check your vehicle registration card, which displays the VIN prominently.
5. Insurance Card
Similar to your registration card, your insurance card usually includes the VIN.
6. Underbody of the Vehicle
In some cases, the VIN may be stamped into the frame or body of the vehicle, visible from underneath. However, this method requires lifting the vehicle or crawling under it, so proceed with caution.
Once you have located the VIN, make note of it for later use. This number is crucial for unlocking your GM radio.
Locating the Radio’s Serial Number
The serial number is crucial for unlocking your GM radio. Here are a few easy steps to locate it:
