Why Did the Radio Lock and Ask 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.
From Serial Number to Unlock Code for your Dodge Caravan - Explained
- Instead of contacting Dodge dealer or searching forums you can retrieve the code online using the radio S/N.
- Start by finding the serial number. You will always find it on the unit itself, and in some cases it can be visible on the Caravan's display.
- Enter it into the form above, and our system will generate the correct 2020 Caravan unlock code.
- After receiving your code, input it using Caravan's radio controls to release the blockade fully.
- The entire process takes less than a minute for most users and requires minimal effort.
How Code Entry Works on Your Dodge Radio
After generating the correct unlock code based on the S/N, you can restore default functionality by entering it into the unit.
The code entry process depends on the radio interface, 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 SAFE displayed on screen.
Entering Process
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.
Detailed Input Instructions for Caravan 2020
Once the unlock code has been retrieved for a 2020 Grand Caravan radio, it can be entered straight at the head unit - no scan tool or dealer visit is required.
- Limited attempts: Mopar head units only accept a small number of incorrect tries (commonly three) before going into a long lockout/WAIT state, so confirm each digit before pressing it.
- Place the ignition in RUN/ACC so the radio powers up but the engine stays off.
- Wait for the display to show
CODE,Enter Anti-Theft Code, or a similar prompt. - On the RBZ/RHB MyGIG (6.5-inch) units, type the digits using the on-screen number pad; on the base RES head unit, press the numbered preset buttons (1-6) in sequence.
- Confirm the entry with the on-screen OK/Enter button on the MyGIG units, or with the tune/menu knob (or labelled enter button) on the RES.
- If
WAITor a similar timeout appears after the failed-attempt limit is reached, leave the radio powered with the ignition in RUN for a continuous 30 minutes before trying the correct code again.
Finding the Radio S/N for Dodge
The useful fact to know is that factory radios use a specific S/N to identify each unit.
The anti-theft system links the code directly to the serial.
Unlike car-specific data such as VIN or registration information, it is not determined by the model or production year, so you'll be able to get it even if you have a radio that you installed afterwards.
Depending on the maker and radio installed in your Dodge Caravan, the access method varies.
These are the most reliable ways to locate it.
Identify Your 2020 Caravan's Factory Radio
2020 was the final year of the Grand Caravan, and the radio lineup ended exactly where it began in 2013 - the legacy Mopar trio with no Uconnect 8.4 platform ever introduced. Identify yours below:
- RES - Media Center 130 (base). Non-touchscreen AM/FM/CD radio. Small monochrome single-line display, hard preset buttons and rotary tune/volume knobs - no screen graphics, no NAV button, no factory Bluetooth. Standard on SE/SE Plus and the most common fit out the door.
- RBZ - 430 MyGIG (6.5" touchscreen, no nav). Glossy black bezel, 6.5-inch color touchscreen, hard buttons for Radio, Media, Controls, More and Phone flanking the screen. No NAV soft key on the home page because it has no navigation hardware. Standard on SXT and GT - the dominant touchscreen variant by far.
- RHB - 430N MyGIG (6.5" with Garmin nav). Externally identical to RBZ - same Mitsubishi-built 6.5-inch screen, same bezel, same hard keys. The on-screen tells: a NAV soft key on the home menu, Garmin splash logo at startup, and a 28GB hard drive for stored music. Rare option even by 2020.
- Optional rear-seat DVD entertainment. Overhead 9-inch flip-down headliner screen with a separate DVD player in the lower dash and wireless IR headphones - orderable with any of the three head units.
Display-Based Serial Number Retrieval
Try the following for your 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.
Manufacturer Label Inspection
If the serial number cannot be accessed via display, use the pull-out method.
Most Dodge Caravan original radios include a label with the serial number printed on the casing.
Step-by-Step:
- Switch off the vehicle.
- Remove the dashboard frame surrounding the radio.
- Loosen the fasteners.
- 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.
Access the Serial by Releasing the Radio
The factory head units offered on the 2020 Grand Caravan - the final model year before the nameplate was retired - continued with the same legacy lineup: the RES single-CD radio (standard on most trims), the RBZ MyGIG 430 (6.5-inch touchscreen, with the Single-DVD Entertainment Group), the RHB MyGIG 430N (6.5-inch touchscreen with Garmin navigation, 28 GB hard drive), and the optional REZ rear-seat DVD entertainment module. None of these legacy radios expose the serial through the screen, so the head unit has to come out for the printed chassis sticker to be read.
- Safety first: switch the ignition off, remove the key, disconnect the negative battery terminal, and wait several minutes; never disturb the yellow airbag/SRS connectors and use plastic trim tools to keep clips and metal contacts intact.
- 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.
- Ease the centre dash bezel forward at the lower edge using a plastic pry tool and work up the sides; on the post-2011 Caravan dash the bezel is held by four friction clips with no visible screws.
- With the four clips released, lay the bezel aside on a soft cloth - on this body it does not need to be unplugged from any harness to free the radio.
- Remove the four screws securing the radio chassis to the dash bracket.
- Slide the radio forward and disconnect the antenna lead and the multi-pin power/data harnesses at the rear.
- The serial number is printed on a barcode/sticker label on the top or side of the chassis next to the part number and supplier markings; the REZ rear-seat DVD module wears the same kind of printed label on its own case.
- Photograph the label up close and double-check ambiguous characters such as 0/O and 1/I before submitting the serial.

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.
S/N Patterns and Prefixes
The factory radios fitted to the 2020 Grand Caravan are legacy Mopar head units rather than the later Uconnect 8.4 platform, so the prefix on the chassis label varies with which radio was specified and which supplier built it.
RBZ MyGIG 430 and RHB MyGIG 430N
- These Mitsubishi-built MyGIG units typically print an alphanumeric serial on the case sticker.
- Common Mopar/MyGIG prefixes seen on this generation include
TM9alongside otherT-style codes. - The serial usually runs as a continuous block of letters and digits with no dashes or spaces.
RES (single-CD)
- The base RES head unit usually carries a Mopar-style serial on a chassis sticker.
- Treat the printed label on the unit itself as the authoritative reference and copy each character exactly.
REZ rear-seat DVD module
- The optional REZ overhead DVD entertainment unit also wears a printed chassis label with its own serial.
- If codes are needed for that module, transcribe its serial separately and avoid guessing unclear characters.
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.
