Identify Your Factory Radio
Not sure if your vehicle is equipped with the Chrysler Uconnect 8.4 UJM? Check the design, controls, display and features listed below against your factory radio.
Identifying details:
- 8.4" touchscreen in the centre of the dash
- Shipped for the Right-hand drive / Rest of World market
- Sales code UJM on the chassis label
- Serial number starting with TM9
You most likely have the Chrysler Uconnect 8.4 UJM if:
- the chassis label carries the UJM sales code
- the serial on the label starts with TM9
- the vehicle was built between 2017-2020
- the display matches the Uconnect 8.4 8.4" touchscreen
UJM is RHD mid-spec. If your steering wheel is on the left, you do not have UJM - check the UA-/UC-/UD-/UG- pages instead.
What Is the Chrysler Uconnect 8.4 UJM Radio?
Fitted as factory equipment in selected Chrysler models, the Chrysler Uconnect 8.4 UJM handles audio playback and vehicle integration from the factory. Depending on the version, it can also add Bluetooth, touchscreen operation, CD/DVD playback, navigation or wider multimedia support.
Uconnect 8.4 UJM is the right-hand-drive/Rest-of-World Panasonic 8.4-inch mid-spec head unit (the "J" middle letter denotes ROW/RHD). RHD-optimised UI, mid-tier feature set between UJQ and UJV.
Chrysler used the Chrysler Uconnect 8.4 UJM on selected models produced between 2017-2020, typically alongside the Panasonic multimedia platform. It is one of the factory units most often encountered from that era.
Common features on this unit:
8.4" touchscreen
AM/FM radio
Bluetooth hands-free and audio streaming
USB media playback
SiriusXM satellite radio*
Steering wheel control support
Anti-theft security code
*Availability depends on the vehicle configuration.
Like many factory-installed radios, the Chrysler Uconnect 8.4 UJM is secured with an anti-theft system. If power is interrupted after replacing or disconnecting the vehicle battery, the unit may request the original radio code before it can be used again.
Platform details and official documentation are available from the official Uconnect site.
Step One: The Serial Number
The code is generated from the radio's own serial number, so that number is the only thing you need before ordering. It is printed on the factory sticker of the unit itself, not in the vehicle documents.
On the Chrysler Uconnect 8.4 UJM: Top of the chassis label. Pull the radio.
Getting to the label:
- Slide the radio out of the dash - most units need a pair of release keys, which cost a few dollars online.
- Read the serial from the factory sticker on the housing, next to or under the barcode.
- Copy it into the form precisely as printed; the checker catches any typo before payment.

How Owners End Up on This Page
A locked Chrysler Uconnect 8.4 UJM is nearly always the result of one of four everyday situations, none of which mean anything is broken.
A used car with a locked radio
Second and third owners rarely get the code card. The radio itself still carries everything needed - its serial number.
Back from the mechanic, radio locked
Mechanics often disconnect the battery before electrical work. The car comes back fixed and the radio comes back locked - expected, not a fault.
A unit from a breaker
Replacement radios are the textbook case: every unit has its own code tied to its own serial. Read the serial off the newly fitted radio and order for that one.
The battery was disconnected
The most common trigger by far: the moment the battery is swapped, the radio forgets it was ever unlocked and asks for its code on the next start.
The way out is the same in every case: serial number in, original code out, within seconds.

Once the code arrives
Nothing to install and no tools needed - just the four digits.
- Put the key in accessory position so the unit powers up and asks for the code.
- A four-digit keypad appears on the display.
- Key in the code, one digit at a time, left to right.
- The unit checks the code automatically on the last digit.
- Right code in, lock screen gone - the radio is back to normal.
Common problems
Too many wrong attempts
After a few wrong entries the radio stops accepting codes for a while - cutting power only restarts the clock. 30-minute WAIT after three wrong codes.
Where the number actually is
The serial is on the unit itself, not in the vehicle papers or on the dashboard. Top of the chassis label. Pull the radio.
The radio locked itself again
Expected behaviour: the security system trips again whenever power is cut. Battery service.
I am not sure I have the right variant
Close relatives of this unit look almost identical from the driver's seat. UJM is RHD mid-spec. If your steering wheel is on the left, you do not have UJM - check the UA-/UC-/UD-/UG- pages instead.
Note the four digits somewhere safe - they are yours for good and reusable after any power cut.
Frequently Asked Questions
Real Reviews From Our Customers
A few of the latest reviews left after an unlock - the full list is on the reviews page.
"This was a simple procedure. My Chrysler 300s, I found out my radio S/N (I had to disassemble the radio to get it) and on my vehicle I had 2. The main unit was the right S/N to use and paid my fee, at the same time received my code. It beats paying an $100 + to get it from the dealership."
I was afraid this was a scam, but I took a chance and it worked perfectly. I bought the radio from a junkyard on ebay and of course it was locked. The unlock process was very easy and I received the code within seconds...
Leslie Fonk - Chrysler
Had to replace the head unit and bought one on eBay but the anti theft code wasn’t provided. This option to get it worked out well
