How to Locate the S/N on a Cherokee
To retrieve the correct radio code, you will need the serial number from your Jeep Cherokee's radio unit.
You may be able to find it in one of two places. Common labels to look for: S/N, SN, Serial, Serial Number.
1. Getting Cherokee's S/N on the Infotainment
The Jeep Cherokee KL (2014–2023) came with three different Uconnect configurations. The first step is identifying which one you have, because each uses a different method to access Dealer Mode.
8.4" Classic (2014–2018): Hold Fan Up + Fan Down + Front Defrost for 5 seconds → Dealer Mode. Navigate: System Info → Radio Part Info → Serial Number. Also works via Engineering Menu: hold Temp Up + Temp Down for 5 seconds.
Uconnect 7" (all years with this screen): Hold Temp Up + Temp Down for 5 seconds → Engineering Menu opens. Navigate: System Info → Target Main Data → Serial Number.
8.4" NEW (2019+): Press the bottom-left + bottom-right plastic bezel edges simultaneously until Dealer Mode opens. Navigate: System Info → Radio Part Info → Serial Number. Serial: 14 characters, e.g. T00AM394958584.
2. Locating your Serial Number on the Radio Itself
The serial number is usually located on a sticker attached to the head unit.
Step 1: Turn off the vehicle.
Step 2: After that, remove the dashboard trim.
Step 3: Then unscrew the radio brackets.
Step 4: Carefully pull the radio forward partially (Be careful not to damage the cables that the unit is connected to).
Step 5: Look for the serial on the side of the unit.
Step 6: Write down the full number carefully and come back to our website so that we can generate the code.
Important: Differentiate the Serial Number for the Part Number!

Physical Radio Removal (if Dealer Mode is unavailable)
If the on-screen method is not available on your vehicle, the radio can be physically removed to read the serial number label on the top or side of the unit:
- Remove the trim bezel – Gently remove the dashboard trim surrounding the radio using a plastic trim removal tool. The bezel is held by friction clips.
- Unscrew the mounting bolts – Remove the 4 mounting screws (usually Torx or Phillips) securing the radio to the dash frame.
- Slide the unit forward – Gently pull the radio out far enough to see the label. Do not disconnect the wiring harness unless necessary.
- Locate the serial number label – Locate a white or silver sticker with a barcode on the top or side of the unit. The serial number is a 14-character alphanumeric code (e.g.
T00AM394958584).
For step-by-step guidance with video tutorials for specific vehicles, see our Uconnect radio removal guide.

When Your Jeep Cherokee Radio May Ask for a Code
Many drivers encounter radio lock problems on their Cherokee after power loss.
Below are the most typical situations when this can happen.
Battery Replacement Radio Code Problem
A disconnected battery is the most common reason a Jeep Cherokee radio asks for a code.
Even a momentary voltage drop is enough to activate the built-in security system.
Additional Scenarios
- Installing a replacement head unit will require the original anti-theft code.
- Jump-starting the vehicle can trigger anti-theft mode, requiring the PIN.
- A fuse removal can cause the Jeep Cherokee radio to request a security code.
- After an ECU or software reset, the radio may enter security mode.
Free Things to Try
Before you decide to pay, it's worth checking a few places where the code is often stored.
Some owners find their Jeep Cherokee radio code without needing any tools or paperwork.
Here are the most common things to check first.
Check the Owner's Manual and Paperwork
- In your car paperwork from the previous owner.
- Inside the center console, sometimes on a small card.
- In the trunk, on a radio label.
- In the owner's manual, often on a sticker page.
- On the head unit itself, if it was removed before.
Can You Get a Jeep Cherokee Radio Code from the Dealership?
Dealerships can generate your radio code by checking the vehicle records in their system.
They typically ask for registration and ID before sharing the security PIN.
This is the official way to restore access to the factory radio.
Potential Downsides:
- Dealers frequently bill for the code (sometimes more than 100$).
- You may need to visit the dealer during business hours.
- Some imported or older radios may not be in their database.
- The lookup is often not instant and may require waiting.
How to Enter the Security Code on Your Cherokee
Once you have the Jeep's radio code, you can enter it using the radio buttons.
Most radios display a "CODE", "ENTER CODE", or "----" message when they are locked.
You typically use the preset buttons to input the code.
After entering the full code, the radio will restore normal operation.
To input the unlock code on your Uconnect radio:
- When the radio is locked, the screen will display "ENTER CODE" or show four dashes (----).
- Use the on-screen keypad (touchscreen models) or the preset buttons (non-touchscreen models) to enter each digit of your 4-digit code.
- After entering all 4 digits, the radio will unlock automatically – no need to press a confirm button.
Tip: Ensure you enter the code carefully. Three incorrect attempts will trigger a temporary lockout.
