If you own a Jeep (such as a Wrangler, Grand Cherokee, Cherokee, or Renegade) and your battery has recently been disconnected or replaced, you’ve likely encountered a common annoyance: the factory radio has entered a locked security state, demanding a PIN or "Anti-Theft Code."
Factory head units across the Jeep lineup—including Uconnect systems and classic Chrysler-based units—use this lockout as a security feature to prevent theft. While dealerships often charge high fees and require days of waiting to provide the code, you can resolve this yourself in just a few minutes.
Step 1: Locate Your Jeep Serial Number
To calculate your unlock code, you need the unique identifier of your unit.
Remove the Head Unit: Carefully use a trim tool to remove the dash bezel and unscrew the radio unit.
Read the Label: Locate the white or silver barcode sticker on the back or top of the metal casing.
Identify the Serial: Look for a string starting with T, CH, or a specific manufacturer code. You will need this exact serial number to retrieve your PIN.
Step 2: Instantly Generate Your Jeep Radio Code
Once you have your serial number, there is no need to visit a service center. You can retrieve your factory security code instantly using a dedicated online lookup tool:
For Specific Instructions & Unlocking: Head over to the dedicated Jeep Radio Code page to submit your details and get your code fast.

Step 3: Entering the Code on Your Jeep
Once you have received your 4-digit security code, entering it is straightforward:
Turn your ignition key to the ON or ACC position and power on the radio; the display should prompt you for the code.
Use the preset station buttons (1 through 4) to input your code:
Button 1: Press repeatedly for the first digit.
Button 2: Press repeatedly for the second digit.
Button 3: Press repeatedly for the third digit.
Button 4: Press repeatedly for the fourth digit.
Confirm the code by pressing the "Enter," "Seek," or "CD" button (depending on your specific head unit model). The radio will unlock, and you can get back on the road.
Note: Pay close attention to your inputs. If you enter the incorrect code multiple times, the unit will trigger a "WAIT" or "LOCKED" state, requiring you to leave the ignition turned ON for up to one hour to reset the security timer.
