Radio Serial Number Explained - Finding It on Your Dodge
Very important thing to know is that factory radios use a specific serial number to identify each unitindividually.
Your anti-theft system matches the code directly to the serial.
Different from car-specific data like VIN or registration information, it is not determined by the model or production year, so you'll be able to retrieve it even if you have an aftermarket radio.
Depending on the manufacturer and radio installed in your Dodge Journey, the access method varies.
These are the most reliable ways to find it.
Radios Offered in the 2016 Journey
For 2016 the Journey kept the same Uconnect 3 (3C) generation lineup it had carried since 2011 with no platform refresh. The base Radio 4.3 / Uconnect 4.3 remained the standard head unit on SE/AVP - a 4.3-inch colour display with AM/FM/CD and hard preset buttons - while the upgraded Uconnect Touch 4.3S added touchscreen response and SiriusXM on SXT. The volume touchscreen choice was the Uconnect 8.4 (sales code RE2), an 8.4-inch Continental-built unit without navigation and with the home menu running on-screen rather than via hard keys around the bezel. The top-tier touchscreen was the Uconnect 8.4N (sales code RB5), identical to the RE2 from the front but with Garmin-based navigation, HD Radio and SiriusXM Travel Link enabled - identifiable by the NAV soft key on the home menu and the Garmin boot logo. The Journey did not move to the newer Uconnect 4 (4C) platform that other FCA models were starting to adopt for 2016.
Accessing the Serial Number Through the Radio Menu
Try the following for your 2016 Dodge Journey:
The 2016 Dodge Journey serves as a practical family vehicle and comes with the Uconnect 8.4" (RA3) infotainment system. Finding the serial number is done via Dealer Mode.
Climate Button Method:
- Turn the ignition to ACC or ON.
- On the Journey's center stack, locate the Climate Up, Climate Down, and Front Defrost buttons below the 8.4" screen. Press and hold all three simultaneously for 5 seconds.
- Dealer Mode opens on the screen.
- Select: System Info → Radio Part Info → Serial Number.
Backup Method: Hold Temperature Up (red) and Temperature Down (blue) for 5 seconds to enter Engineering Mode, then navigate to the same menu.
Screen-Based Serial Lookup Method
If your 2016 Journey has the Uconnect 8.4 (RE2) or 8.4N (RB5) head unit, the radio serial number is usually viewable on screen via the factory dealer/diagnostic mode - no removal required. The base Radio 4.3 / Uconnect 4.3 does not surface this information on its display, so for that head unit you have to read the printed label on the chassis after pulling the unit.
Place the ignition in RUN/ACC so the radio powers up but the engine stays off. Once the Uconnect home screen has finished loading, press and hold the driver-side temperature UP, the driver-side temperature DOWN, and the front DEFROST button on the climate panel below the screen at the same time for roughly 7 seconds. The display switches into a diagnostic/dealer menu showing radio information, software revisions and serial numbers - read the radio serial number entry exactly as printed and double-check ambiguous characters such as 0/O and 1/I before transcribing it. Switch the ignition off to exit; the screen returns to normal on the next start. If the three-button combination has no effect, the radio is most likely the base 4.3 unit and the serial will need to be read from the chassis label instead.
Access the Serial by Pulling Out the Unit
If the serial number cannot be accessed on-screen, use the pull-out method.
Most Dodge Journey factory radios include a label with the serial number printed on the casing.
Step-by-Step:
- Power down the vehicle.
- Detach the trim surrounding the radio.
- Unscrew the clips.
- Pull the unit outward to access the label.
The serial number is usually located near the manufacturer sticker.
If Dealer Mode is unresponsive on your 2016 Journey, the radio must be physically removed to find the serial label. The Journey's compact center stack is straightforward to work on:
- Remove the center trim bezel – The Journey's trim bezel surrounds the radio and climate section. Insert a plastic pry tool at the lower edge and gently pry along the perimeter to pop off the snap-in clips.
- Remove the 4 mounting screws – Typically Torx T20 screws at the radio frame corners.
- Pull the radio forward – Slide the unit out just enough to view the serial label on the side surface.
The serial is a 14-character barcode label. Wiring can stay plugged in.
Manufacturer Label Inspection
For 2016 Journeys with the base Radio 4.3 / Uconnect 4.3, or if the dealer-mode shortcut does not bring up the diagnostic screen on the 8.4 unit, the head unit has to come out so the printed chassis label can be read.
Safety first. Turn the ignition off, remove the key, disconnect the negative battery terminal, and wait several minutes before touching wiring. Avoid the yellow airbag/SRS connectors entirely and use plastic trim tools so nothing shorts or breaks.
Tools you will need. Plastic trim removal kit, Phillips screwdriver, small Torx bit set, flashlight, and a 7 mm socket on hand for any deeper retaining bolts.
Removal overview. Start at the lower edge of the centre dash bezel and ease it forward with a plastic pry tool, working up the sides. The bezel is held in by spring/friction clips and pops free with steady pressure - no visible screws on the face of the bezel. Once the clips release, tilt the bezel out and unplug the connector for the hazard switch and any HVAC/auxiliary plugs on the back of the panel before lifting it clear, then set it aside on a soft cloth to protect the gloss finish. Remove the screws (typically four) securing the radio chassis to the dash bracket, slide the unit forward, and disconnect the antenna lead and the multi-pin power/data harnesses on the rear.
Where the serial sits. The serial number is printed on a barcode/sticker label on the top or side of the radio chassis, next to the part number and Mopar/supplier markings.
Tips. Photograph the label up close in good light and double-check ambiguous characters such as 0/O and 1/I before submitting the serial.

Common S/N Formats Used on 2016 Journey Units
The 2016 Dodge Journey with the 8.4" Uconnect (RA3) features these serial formats:
T00AM– Harman VP2 Uconnect (most common format)T00BE– Continental buildTM9– Older Harman production
Radio designation: RA3. Serial length: 14 characters. Note: The Journey kept the classic RA3 system through 2020 — even the final production years.
Reminder The Journey's label also shows a part number (P05064... or 68...) — only the serial is used for code generation.
Standard Serial Number Patterns on This Radio
The prefix printed on the chassis label varies with which head unit was specified and which supplier built it.
Uconnect 8.4 (RE2) and 8.4N (RB5)
These Continental-built 8.4-inch head units typically print an alphanumeric serial on the case sticker. Common Mopar Uconnect 8.4 prefixes from this generation begin with the letter T followed by additional letters and digits, with the serial running as a continuous block of characters with no dashes or spaces. Treat the printed label as authoritative and copy each character exactly.
Radio 4.3 / Uconnect 4.3 (Touch 4.3S)
The base 4.3 head unit usually carries a Mopar-style serial on a chassis sticker. Avoid guessing characters that look unclear and copy what is printed on the label rather than relying on any assumed prefix.
How Our Radio Code Generator Works for 2016 Dodge Journey
Getting your radio code takes only a few simple steps.
- Locate the radio's serial number - this is the only information required by our side.
The difference with the dealership lookup is that no VIN or paperwork is needed. - When you've found the S/N, type it into the form above.
Our system checks it against a database of supported factory radios and automatically catches the matching security code. - In most cases, the code will appear instantly on the screen after payment and is also sent to your email for backup.
If manual verification is required (rare situations), you'll be notified before checkout. - Once you get it, simply enter it into the radio to restore full functionality.
Code Entry Instructions
Once you receive the correct unlock code based on the serial number, you can restore default functionality by entering it into the unit.
The code entry process depends on the head unit design, but most 2016 Journey systems follow a similar structure using preset buttons, touch controls, or rotary knobs - depending on if it's a factory or an aftermarket unit.
You will typically see ENTER CODE displayed on screen.
In-depth Entering Instructions for Journey 2016
Entering the code on the 2016 Journey's Uconnect 8.4":
- Ignition ON. Screen shows "ENTER CODE" or ----.
- Use the touchscreen on the Journey's 8.4" screen to enter your 4-digit code.
- The radio restores after the 4th digit — nothing else needed.
Lockout: 3 wrong attempts = 60-minute lockout. Keep ignition ON throughout. Turning off the ignition restarts the wait.
Entering Process Explained
Once the unlock code has been retrieved for a 2016 Journey radio, it can be entered straight at the head unit - no scan tool or dealer visit is required.
Limited attempts. After three successive incorrect codes the radio drops into a WAIT lockout state, so verify each digit before pressing it.
Entering the code. Place the ignition in RUN/ACC so the radio powers up but the engine stays off. Wait for the display to show CODE, Please Enter Anti-Theft Code, or a similar prompt. On the Uconnect 8.4 (RE2) and 8.4N (RB5) units, key the four digits using the on-screen number pad and confirm with the on-screen OK/Enter button. On the base Radio 4.3 / Uconnect 4.3 unit, press the numbered preset buttons (1-6) in sequence to enter each digit and confirm with the tune/menu knob or labelled enter button as prompted on the display.
If a wrong code was entered. If WAIT appears after three failed attempts, leave the radio powered with the ignition in RUN for a continuous 30 minutes (the vehicle may be driven during this time) before trying the correct code again.
Why Is the Radio Asking for a Code?
Journey owners face radio lockouts typically due to:
- Battery replacement — the Journey's use as a daily driver means batteries wear out with heavy use, and each replacement activates the code screen.
- Dead battery from short trips — family crossovers used mainly for short errands may not charge fully, eventually causing a dead battery and locking the radio.
- Blown fuse — fuse replacement also interrupts power and locks the radio.
- Used purchase — the Journey was a popular family used buy without the prior code means the radio is locked from the start.
Your code is permanently tied to the serial number and remains valid.
Troubleshooting Common Radio Problems - Journey 2016
On the 2016 Journey, the RA3 radio label contains the serial and the part number:
- Serial number — 14 characters, beginning with
T00AM,T00BE, orTM9. Use this. - Part number — starts with
P05064or68. Ignore this.
On the Journey, Dealer Mode is the quickest way: System Info → Radio Part Info → Serial Number. No removal needed.
The Journey's Uconnect 8.4" uses touchscreen-only input for code entry — no physical buttons are used. Once "ENTER CODE" shows:
- Tap each digit directly on the on-screen pad.
- The radio auto-unlocks after the 4th digit — no "OK" button is needed.
Should taps not register, cycle the ignition and wait 30 seconds.
After 3 wrong entries on the Journey's Uconnect, a 60-minute lockout kicks in. The screen displays "WAIT":
- Leave the Journey's ignition ON — engine off is fine but ignition must remain ON.
- Wait the full 60 minutes to pass.
- Turning the ignition off restarts the 60-minute timer.
Once clear, re-enter the correct code.
When no code prompt shows after a battery event:
- Ensure ignition is in ON (not ACC) and wait 15–20 seconds for the system to fully start.
- Check the fuse box — a blown fuse prevents the radio from starting.
- Certain models may require a brief button press to trigger the code prompt.
Should nothing appear, a blown fuse is likely the problem.
A rejected code on the Journey's Uconnect 8.4" is usually caused by a serial mismatch. The RA3 label displays both a serial number (14-char code, starts with T00AM, T00BE, or TM9) and a part number (P... or 68...) on the same sticker.
Double-check the number via Dealer Mode or the physical label and contact support for a free re-check if needed.
