Where to Search for the Serial Number
To generate the right unlock code, you first need the radio's serial.
Depending on your model, you can display it on the radio screen or locate it on the unit.
Common abbreviations are: Serial Num. / S/N / Serial Number etc.
These are the typical ways to get it:
1. Find the S/N on Jeep Grand Cherokee's Screen
Every generation of the Jeep Grand Cherokee with a touchscreen gives you direct access to the serial number via Dealer Mode — no removal, no tools. Whether you drive a WK2 Laredo, a Summit, an Overland, or a Trackhawk, the same approach works across the board.
Follow the generation timeline below to find your method:
WK2 — 2011–2018 (Uconnect 8.4" Classic): Two options. Option A: Hold Fan Up + Fan Down + Front Defrost for 5 seconds → Dealer Mode opens. Option B: Hold Temp Up + Temp Down for 5 seconds → Engineering Menu. Both lead to: System Info → Radio Part Info → Serial Number.
WK2 — 2019–2021 (Uconnect 8.4" NEW): Press the bottom-left + bottom-right plastic bezel edges simultaneously and hold until Dealer Mode opens. Navigate to the serial via the same path.
WL — 2022+ Grand Cherokee L and 4xe (Uconnect 5): Uconnect 5 uses the same bezel-edge press to reach Dealer Mode, then the same navigation. If that fails on newer firmware, check Settings → System → About in the infotainment menu.
Serial format: 14 characters, e.g. T00AM394958584. Physical removal is only needed if all on-screen methods are blocked.
2. The Serial Number on the Radio Housing
The serial number is usually found 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 connections).
Step 5: Search for the serial on the rear 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: Don't mix the Serial Number for the Part Number!

Physical Radio Removal (if Dealer Mode is unavailable)
If the on-screen method does not work 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 – Carefully pry off 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 – Look for 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.

Serial Number Prefixes You'll See on Jeep Grand Cherokee
To unlock your radio, find the serial starting with T00AM, TM9, or A2C. Important: do NOT use serials ending in W, J, L, or S — those are screen/DVD/amplifier modules, not the main radio brain.
Common Jeep Grand Cherokee Radio Code Problems
Many owners encounter security code prompts on their Grand Cherokee after power loss.
Below are the most common situations when this can occur.
After a Battery Change
A replaced battery is the most common reason a Jeep Grand Cherokee radio asks for a code.
Even a momentary power loss is enough to activate the built-in security system.
Additional Scenarios
- After an ECU reset, software update, or electrical repair, some Jeep Grand Cherokee radios ask for a code.
- After a boost start, the radio may lose power and request a security code.
- When the head unit is removed, it usually requires the original code.
- If a fuse blows, the radio can enter anti-theft mode.
Before Paying for Help
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.
Check Inside the Vehicle
- In your service book from the previous owner.
- In the vehicle handbook, often on a sticker page.
- Inside the glovebox, sometimes on a label.
- On the head unit itself, if it was serviced earlier.
- In the boot compartment, on a service sticker.
Can You Get a Jeep Grand Cherokee Radio Code from the Dealer?
Dealerships can generate your radio code by checking the VIN 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.
Things to Consider:
- The lookup is often not instant and may require waiting.
- Dealers frequently bill for the code (sometimes more than 100$).
- You may need to contact service support during business hours.
- Some imported or older radios may not be in their database.

Jeep Grand Cherokee Radio Security Code Explained
A radio code, also known as an anti-theft code is a unique numeric unlock key that reactivates your car audio system after it has been disabled.
This anti-theft code is triggered when the radio detects a power interruption.
Car manufacturers use this security system to prevent stolen radios from being reused.
If power is cut, the radio locks automatically and asks for the CODE before it can function normally.
Once the valid numbers combination is entered, the stereo is unlocked.
Frequently Asked Questions about Jeep Grand Cherokee Unlock Code
Yes. Each car stereo has its own unlock code.
If you install a replacement radio, you'll need the code for that specific unit.
Many factory radios use a security code, but some versions require one.
Whether a code is needed varies by the installed head unit and the vehicle generation.
Free are rarely available.
Some service documents may help, but most codes require a database lookup.
The only free way would be to check your car and its manual to see if you have it written down.
Uconnect is the infotainment system developed by Stellantis (formerly Fiat Chrysler Automobiles) and used across Chrysler, Dodge, Jeep, Ram, Fiat, and Alfa Romeo vehicles. Most Uconnect radios feature an anti-theft protection system that activates whenever the radio loses power – for example after a battery replacement, a dead battery, or electrical work.
When triggered, the radio displays "ENTER CODE" and will not function until the correct 4-digit unlock code is entered. The code is linked to the radio's serial number, not the vehicle's VIN, which is why finding the serial number is the first step to unlocking.
Yes, in most cases. Uconnect systems from 2013 onwards feature a hidden Dealer Mode (or Engineering Mode) diagnostic menu that displays the serial number directly on screen. You can access it by holding specific button combinations – without any tools or removal.
However, some 2020+ models may have had Dealer Mode disabled via software updates. If you cannot access the on-screen menu, the radio must be physically removed to read the serial number label on the unit. See our full Dealer Mode guide for step-by-step instructions with video tutorials.
Yes. The Wrangler JK (2007–2018) uses older Uconnect models (430/430N/730N) with physical preset buttons, while the Wrangler JL (2018+) uses the newer Uconnect 4C with an 8.4" or 7" touchscreen. Both generations require a radio code after power loss, but the method for accessing Dealer Mode is different.
For the JK, use the climate control button method. For the JL, try the screen bezel edge method (8.4") or the temperature button method (7"). See our Uconnect Dealer Mode guide for specific instructions.
