Before ordering a radio code it is important to confirm the exact model. Match the design, controls, display and features below with the unit in your dashboard.
Visual clues on this unit:

- A navigation unit - maps installed from the factory
- Shipped for the Japan market
- The chassis label carries the RM4 VP4 JP sales code

- the serial on the label starts with T00AM, T00BE, T0012
- the car left the factory between 2015-2018
- the screen is the 8.4" touchscreen fitted to the Uconnect 8.4
Lowest-volume regional variant. Japan-only - if your vehicle is not a Japan-market import, you have a different RA/RG/RJ unit.
How to Read the Serial Number Off Your Uconnect 8.4 RM4 VP4 JP
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 this unit: Top of the chassis label.
Getting to the label:
- Bring the radio out of its slot; release keys do it in a minute and nothing needs disconnecting.
- Read the serial from the printed label on the housing, next to or under the barcode.
- Copy it into the form letter for letter; the checker catches any typo before payment.

Introducing the Uconnect 8.4 RM4 VP4 JP
Fitted as factory equipment in selected Chrysler models, the Uconnect 8.4 RM4 VP4 JP 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 RM4 (VP4 Japan) is the Japan-market 8.4-inch navigation Uconnect - VP4 hardware with Japanese language UI, JIS-compliant DAB tuner, and Japan-specific map data.
The Uconnect 8.4 RM4 VP4 JP was installed in various Chrysler models between 2015-2018. It was commonly fitted to vehicles built on the Harman multimedia platform and remains one of the more recognisable factory radios of that period.
Common features on this unit:
8.4" touchscreen
AM/FM radio
Built-in navigation with factory maps
Bluetooth for hands-free calls and music streaming
Media playback over USB
SiriusXM satellite radio*
Steering wheel control support
Anti-theft security code
*Availability varies with the vehicle specification.
As with other Harman factory units, the Uconnect 8.4 RM4 VP4 JP locks itself when power is lost. After a battery disconnect or a workshop visit the screen will prompt for the original security code before any audio returns.
Background on the platform itself is published by the official Uconnect site.
When Does the Uconnect 8.4 RM4 VP4 JP Ask for Its Code?
The lock screen almost never appears out of nowhere - one of these four situations is behind almost every locked Uconnect 8.4 RM4 VP4 JP we see.
A battery swap
A new battery - or a flat one after the car sat for a while - cuts power to the radio, and the anti-theft system arms itself the moment power returns.
A replacement radio
The code does not transfer from one unit to another: the swapped-in unit has a different serial, and that serial is what the code is calculated from.
A repair cut the power
Alternator, starter or fuse-box work usually means disconnecting the battery - and the radio arms its anti-theft as a side effect of the repair.
You bought the car second-hand
No handbook, no code card, seller unreachable - none of it matters. The radio's own serial number carries everything needed to calculate the code.
Whichever of these applies, the fix is identical: the serial number off the radio, the form at the top of this page, and the code is emailed in seconds.

Entering the code on the Uconnect 8.4 RM4 VP4 JP
The code goes into the unit itself, not into the car's menus.
- 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 its usual self.
Things that can catch you out
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 attempts.
The serial is hiding from you
Nothing on the car's menus shows it - the number lives on the radio's own label. Top of the chassis label.
It is asking for the code a second time
By design, every loss of power resets the anti-theft lock. Battery disconnect.
I am not sure I have the right variant
Close relatives of this unit look almost identical from the driver's seat. Lowest-volume regional variant. Japan-only - if your vehicle is not a Japan-market import, you have a different RA/RG/RJ unit.
Note the four digits somewhere safe - they are permanent and reusable after any power cut.
