Finding the S/N on a Grand Cherokee's Radio
The only thing you'll need to get the code is your radio's serial number (not part number!).
On all Jeep's, you can find it in one of these places:
- Directly on the radio screen (by using some combinations of buttons)
- On the radio body itself - you'll need to pull it out and write down your serial (which is not so hard).
Search for something like: Serial, SN, S/N, Serial Num...
1. Find the S/N on Jeep Grand Cherokee's Screen
Jeep Grand Cherokee radio does not display the serial number on the screen.
Unfortunately, the unit must then be physically removed to find the serial on a factory sticker on the radio casing.
2. Locating the Serial Number on the Radio Unit
The serial number is usually printed on a sticker attached to the head unit.
Step 1: Turn off the car.
Step 2: After that, take off the surrounding panel.
Step 3: Then unscrew the radio brackets.
Step 4: Carefully slide the unit out partially (Be careful not to damage the cables that the unit is connected to).
Step 5: Look for the serial number on the side of the unit.
Step 6: Write down the full Serial Number carefully and come back here so that we can generate the code.
Important: Differentiate the Serial Number from the Part Number!

Jeep Grand Cherokee's Most Common Radio Code Triggers
Your radio may lock automatically when it detects a power interruption.
These are the most common scenarios that activate the radio code prompt.

This happens because the radio detects a power reset, which activates the security lock.
Other Possibilities
- Installing a replacement head unit will require the original radio code.
- After an ECU or software reset, the radio may enter security mode.
- A blown fuse can cause the Jeep Grand Cherokee radio to lock.
- Jump-starting the vehicle can reset the radio, requiring the unlock code.
Quick Fixes Before Paying for a Radio Code
Looking for a free Jeep Grand Cherokee Radio Code? Actually, you may find it.
In few cases, the code may already be available in the vehicle itself or in the documentation.
Check these places to save time and money before using an online generator.
Below are the simplest places to look.
Look for it in the Vehicle Itself
- In the vehicle handbook, often on a sticker page.

- In your service book from the previous owner.
- On the head unit itself, if it was serviced earlier.
Getting a Jeep Grand Cherokee Radio Code from the Dealer

They typically ask for registration and ID before sharing the security PIN.
This is the official way to restore access to the factory radio.
Downsides:
- Some imported or older radios may need extra verification.
- You may need to visit the dealer during business hours.
- The lookup is often not instant and may require waiting.
- Dealers frequently bill for the code (sometimes more than 100$).

Now You Have the Code. How to Enter It?
You need to type in the code into the system to unlock your Jeep's radio.
In the locked unit, the screen usually shows a code prompt.
You should use control knob, touchscreen, or radio presets to set each digit, then confirm the code to reactivate the audio system.
If you make a mistake multiple times, you may cause the Grand Cherokee's head unit to block further attempts.
When this happens, the screen can display messages like "CODE ERR", "ERROR", or a blank screen.
To unlock the system, you usually need to leave the radio powered for a waiting period or up to a full hour before trying again.
What Exactly is a Radio Code?
When the radio is disconnected from power, it automatically locks and requires an anti-theft code to be entered before it can be used again.
A factory radio code (also known as an anti-theft code) is a security feature integrated into original car stereos to prevent theft.
This system ensures that a removed radio becomes useless without the original code.
Entering the valid code returns full audio and media functionality.
