Locating the S/N on Your Radio
To retrieve the correct security code, you first need the radio's serial.
Depending on your model, you can see it on the screen or locate it on the unit.
Common abbreviations are: Serial Num. / S/N / Serial Number etc.
These are the typical ways to find it:
1. View the Serial Number on Dodge Durango's Screen
As a mid-size 3-row SUV sharing its WK platform with the Jeep Grand Cherokee, the Dodge Durango benefits from the same Uconnect 8.4" infotainment system. That means the on-screen serial number method that works on a Grand Cherokee also works here — no dashboard removal necessary.
Here is how to do it, depending on your year:
2014–2018 (Uconnect 8.4" Classic): With the ignition in ACC or ON, simultaneously hold Fan Up, Fan Down, and Front Defrost for 5 seconds. Dealer Mode opens on the screen. Alternatively, hold Temp Up + Temp Down for 5 seconds to reach the Engineering Menu. Both lead to: System Info → Radio Part Info → Serial Number.
2019+ (Uconnect 8.4" NEW): Press the bottom-left and bottom-right edges of the plastic bezel frame at the same time. Hold until Dealer Mode appears. Navigate the same path as above to the serial number.
2011–2013: Early Durango models may not have a Dealer Mode display option. If neither button combination does anything, the serial label is on the radio chassis and requires physical removal. The serial is a 14-character code, e.g. T00AM394958584.
2. Locating your Serial on the Radio Unit
To find the serial number, you'll need to remove the head unit from the dashboard.
- Start by turning off the vehicle and removing the trim panel.
- Next, release the clips and slide the radio out to check the label on the side of the radio. Pay attention not to damage the connections.
- Write down the serial number carefully and come back to the website.
- Know that serial number and part number are not the same thing. You will find both of them on the unit, but you only care for the serial.
Accessing the Serial Number in Dodge Durango
The Durango shares its platform with the Jeep Grand Cherokee (WK2), so the removal process is similar. The procedure varies slightly depending on your model year:
Watch removal guides on YouTube
For 2014-2025 models with 8.4" Uconnect:
- Remove the storage tray below the radio—2 hidden 7mm screws secure it from behind.
- Remove the trim panel using a plastic pry tool.
- Unscrew the radio unit—typically 2-4 screws (7mm socket or bolts).
- Support the radio carefully as you pull it forward—there is very little cable slack. Avoid pulling too hard to prevent damaging the connectors.
For 2011-2013 models: The process is similar but simpler, as the earlier dashboard design has fewer integrated components.
Tools needed: Plastic pry tool, 7mm socket, Phillips screwdriver

Typical Dodge Durango S/N Formats
To unlock your radio, find the serial that starts 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 Dodge Durango Radio Code Issues
Many drivers encounter radio lock problems on their Durango after battery-related issues.
Below are the most typical situations when this can occur.
Battery Disconnect Triggering the Radio Lock
A replaced battery is the most common reason a Dodge Durango radio asks for a code.
Even a brief voltage drop is enough to activate the built-in security system.
Other Situations That May Trigger the Code
- A fuse replacement can interrupt the radio and prompt for a code.
- ECU reflashing may trigger the anti-theft mode on some Dodge Durango units.
- Replacing the head unit with a second-hand one requires the code for that particular radio.
- Even a quick battery boost can activate the anti-theft lock.
Possible Free Options
Before you pay for it, it's worth checking a few places where the code is often stored.
Some drivers find their Dodge Durango radio code without needing any tools or paperwork.
Here are the easiest things to check first.
Look Through Car Documentation
- In the vehicle documentation provided with the car.
- In the radio manual, often on a separate page.
- On the back of the radio if the unit was previously removed.
- On a sticker in the door pillar.
- Near the boot panel, where some manufacturers place radio labels.
Through the Dealer
A Dodge dealer can usually look up the security code using your Durango's VIN.
In most cases, you need to visit or contact them and prove ownership.
When it is verified, they can generate the original unlock code for your radio.
Possible Drawbacks:
- You usually need to visit in person and bring ID.
- Dealers often charge a fee for the lookup service and it's sometimes more than 100$.
- The process can take days depending on the model and database.
- Some older Dodge Durango radios may require manual lookup.
Entering the Security Code on Dodge Durango
With your code ready, it's time to enter it into the Dodge Durango's radio.
The locked radio will usually show a blank screen with dashes.
Use the built-in buttons or touch controls to select each number, then press OK to activate the head unit.
Once you have your unlock code, here's how to enter it in your Durango:
Standard method (most 2011-2020 models):
- Turn on the ignition—the radio displays "CODE".
- Use preset buttons 1-4 to cycle each digit into position.
- Press and hold ENTER/OK for 2-5 seconds to unlock the radio.
Touchscreen method (Uconnect 4C/5 in 2021+ models):
Newer Durango models may display an on-screen numeric keypad. Simply tap each digit and confirm.
Note: Some early 2011 models with the RBZ radio system may not have the anti-theft code feature. After 3 incorrect attempts, the radio locks for 30 minutes with the ignition ON.
