Serial Number Location Guide for Dodge Caravan 2016
The initial step is locating the radio S/N.
Most drivers assume the code depends on the Dodge model or year, but actually, the unlock process depends on the unique radio unit's serial number.
The serial is the key used to calculate the correct unlock code.
This is even better, because if you have bought an aftermarket radio, the VIN or other vehicle-specific data wouldn't be of much use.
Depending on the radio version used, you may be able to see the serial directly from the screen or by checking the label on the radio chassis.
Using Hidden Radio Menus to Find the Serial
Try the following for your 2016 Dodge Caravan:
The 2016 Dodge Caravan seats up to 7 passengers and is equipped with the Uconnect 8.4" (RA3) touchscreen. The serial number can be retrieved directly from the screen using Dealer Mode.
Climate Button Method:
- Turn the ignition to ACC or ON.
- In the Caravan's center stack, the Climate Up, Climate Down, and Front Defrost buttons sit below the 8.4" screen. Hold all three together for 5 seconds.
- Dealer Mode opens on the screen.
- Go to: System Info → Radio Part Info → Serial Number.
Alternative: Hold Temperature Up (red) and Temperature Down (blue) for 5 seconds to enter Engineering Mode, then follow the same path.
View the Serial by Pulling Out the Radio
If the serial does not appear in menu, the next step is checking the radio itself.
Many Dodge radios require physical access to the serial sticker attached to the unit.
Common approach:
- Start by completely shutting off the engine - pull the key out.
- Then lift the dashboard bezel.
- Next, unscrew the mounting points and pull the radio forward.
- Look for a printed tag showing the serial number.
If Dealer Mode doesn't work on your 2016 Caravan, the radio needs to be removed to access the serial label. The Caravan's minivan center stack makes the process manageable from the front seat:
- Remove the center bezel – The Caravan's center trim panel covers the 8.4" display and HVAC section. With a pry tool, start at the lower edges to release the friction clips.
- Remove the 4 mounting screws – Torx T20 or Phillips screws at the radio frame corners.
- Pull the radio forward – Slide the unit out to expose the serial label on the top or side unit.
The serial is a 14-character code on a barcode sticker. The wiring harness can stay connected.

Radio Code Input Guide
After receiving 2016 Dodge Caravan radio code from the serial, you're ready to reactivate the radio.

When the radio shows CODE, it means the unit is waiting for the correct numbers.
Entering Process Explained
Entering the unlock code on the 2016 Caravan's Uconnect 8.4":
- With ignition ON, the screen displays "ENTER CODE".
- Tap the on-screen keypad to enter your 4-digit code. The Caravan's 8.4" screen is easily visible from the driver's seat.

How Our Radio Code Generator Works for 2016 Dodge Caravan
Car radios use anti-theft codes tied to the radio unit itself instead of the vehicle model or production year.
- The generator identifies your Dodge radio via serial-based verification.
- When you input the serial into the generator, the system identifies the radio family and generates the code that you need.
- Simply input the digits into the Caravan stereo.
- This approach saves time compared to traditional methods for 2016 Dodge Caravan.
What Caused the Radio to Lock?
Caravan owners face radio lockouts primarily due to:
- Heavy family use battery wear — Minivans used daily for family transport with heavy accessory loads put more load on the battery, making replacements more frequent and every replacement triggers the code.
- Extended parking — family minivans sitting unused between trips can deplete the battery.
- Battery replacement — routine battery service activates the lock.
- Used purchase — Caravans are popular used family purchases, so owners encounter the locked radio.
The code is permanently linked to the radio serial number and never changes.
Understanding Unlock Issues with Your Caravan
The Caravan's Uconnect 8.4" uses touchscreen-only code entry — no preset buttons are used. Once "ENTER CODE" appears:
- Tap each digit on the touchscreen.
- The radio confirms after the 4th digit — no "OK" button is required.
Should taps not register, cycle the ignition and allow 30 seconds.
If the Caravan's radio doesn't show the code screen after a battery event:
- Confirm the ignition is in ON (not just ACC) and wait 15–20 seconds to boot up.
- Check the radio fuse — a blown fuse prevents any display.
- Some Caravan units respond to a screen tap to trigger the code prompt.
If the screen stays dark, a blown fuse is worth checking first.
The RA3 label on the Caravan's radio has two different identifiers:
- Serial number — 14 alphanumeric characters, starting with
T00AM,T00BE, orTM9. This is the one you need. - Part number — begins with
P05064or68. Not used.
Your quickest option: Dealer Mode — System Info → Radio Part Info → Serial Number. No physical removal needed.
Code rejection on this minivan usually indicates the wrong serial was used. The RA3 label contains both the serial (14 characters, prefixed by T00AM, T00BE, or TM9) and the part number (P... or 68...) — only the serial generates a code.
Verify the number via Dealer Mode or the label and reach out for a free re-check if needed.
Three wrong attempts on the Caravan's Uconnect cause a 60-minute lockout showing "WAIT":
- Leave the Caravan's ignition ON — doesn't need to run but key must stay in ON.
- Wait the entire 60 minutes.
- Cycling the ignition restarts the wait from scratch.
After 60 minutes, re-enter carefully with the verified code.
