Why Is the Radio Asking for a Code?
Minivan owners encounter this most often because of:
- Heavy family use battery wear — Family vehicles with constant use of chargers, DVD players, and rear fans drain batteries faster, making replacements more frequent and every replacement triggers the code.
- Extended parking — family minivans parked for extended periods may drain enough to lock the radio.
- Battery replacement — routine battery service activates the lock.
- Used purchase — minivans change hands frequently, so owners find it locked when they buy one.
Your unlock code is permanently linked to the radio serial number and always remains valid.
How Serial-Based Dodge Caravan Radio Unlock Works
- Rather than relying on Dodge dealership lookup or online threads you can find the code online using the radio S/N.
- First locate your radio's serial. You will always find it on the unit itself, and sometimes it can be visible on the Caravan's radio screen.
- Type it into the field above, and our system will retrieve the correct 2020 Caravan unlock code.
- After receiving your code, input it using Caravan's radio controls to unlock the system fully.
- The entire process takes just a short moment and requires minimal effort.
Entering Your Unlock Code
When you obtain the correct unlock code based on the S/N, you can restore normal functionality by entering it into the unit.
The code entry process depends on the control layout, but most 2020 Caravan 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.
Detailed Input Instructions for Caravan 2020
Code entry on the 2020 Caravan's Uconnect 8.4":
- With ignition ON, the screen shows "ENTER CODE".
- Use the on-screen keypad to enter your 4-digit code. The Caravan's 8.4" screen is easy to reach from the front.
- The radio auto-confirms after the 4th digit — no confirm button is required.
Lockout: 3 wrong entries = 60-minute lockout. Leave ignition ON. Turning it off resets the timer.
Radio Serial Number Explained - Finding It on Your Dodge
The starting step is locating the radio serial number.
Many drivers assume the code depends on the Dodge model or year, but in reality, the whole process depends on the unique radio unit's serial number.
The serial is the key used to calculate the correct unlock code.
This is actually better, because if you have an aftermarket radio, the VIN or other Dodge-specific data wouldn't help.
Based on the radio version used, you may be able to see the serial directly from the display or by looking at the label on the radio chassis.
Quick Method: Find the Serial Number on the Screen
These are the steps you should follow for 2020 Dodge Caravan:
The 2020 Dodge Caravan is a family minivan and comes 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 at once for 5 seconds.
- Dealer Mode opens on the screen.
- Navigate 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 navigate to the serial.
Taking Out the Radio to Access the S/N on the Tag
If the serial number cannot be accessed on-screen, use the removal method.
Most Dodge Caravan original radios include a tag with the serial number printed on the chassis.
Steps:
- Power down the vehicle.
- Detach the bezel surrounding the radio.
- Release the clips.
- Slide the unit slightly out to access the label.
The serial number is usually located near the barcode.
If Dealer Mode doesn't work on your 2020 Caravan, the radio must 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 bezel covers the 8.4" display and HVAC section. Using a plastic trim tool, start at the lower edges to release the friction clips.
- Remove the 4 mounting screws – Typically T20 screws at the radio frame corners.
- Pull the radio forward – Slide the unit out enough to see the serial label on the side of the unit.
The serial is a 14-character code on a barcode sticker. The wiring harness can stay connected.

Typical Radio Serial Prefixes and Formats
The 2020 Dodge Caravan's Uconnect 8.4" (RA3) features these common serial formats:
T00AM– Harman VP2 Uconnect (standard format)T00BE– Continental-made variantTM9– Older Harman production
Radio designation: RA3 (or VP2 with optional Beats Audio). Serial: 14 characters.
Note The Caravan's label includes a part number (P05064... or 68...). Only the serial is used for the unlock code.
Fixing Common Code Entry Problems for 2020 Caravan
The Caravan's Uconnect 8.4" uses touchscreen-only code entry — no preset buttons are used. Once "ENTER CODE" appears:
- Press each number on the on-screen keypad.
- The radio confirms after the last digit entered — no "OK" button is required.
If the touchscreen doesn't respond, turn the ignition off and back on, then wait for the system to restart.
If the Caravan's radio doesn't show the code screen after a battery event:
- Ensure the ignition is in ON (not just ACC) and wait 15–20 seconds to boot up.
- Check the radio fuse — fuse failure prevents any display.
- Some Caravan units respond to a screen tap to activate the code entry screen.
Should nothing appear, a blown fuse is most likely the cause.
The RA3 label on the Caravan's radio has two different identifiers:
- Serial number — 14 alphanumeric characters, prefixed by
T00AM,T00BE, orTM9. Submit this. - Part number — begins with
P05064or68. Ignore this.
Your quickest option: Dealer Mode — System Info → Radio Part Info → Serial Number. No physical removal needed.
Three wrong attempts on the Caravan's Uconnect trigger a 60-minute lockout showing "WAIT":
- Leave the Caravan's ignition ON — doesn't need to run but ignition must remain ON.
- Allow the entire 60 minutes.
- Turning the Caravan off restarts the wait from scratch.
Once clear, re-enter carefully with the verified code.
Code rejection on this minivan usually indicates a serial number error. The RA3 label shows both the serial (14-char code, prefixed by T00AM, T00BE, or TM9) and the part number (P... or 68...) — submit only the serial.
Verify the number via Dealer Mode or the label and reach out for a free re-check if needed.
