How the Code Retrieval Process Works for Chrysler Grand Caravan 2020
- Instead of contacting Chrysler dealer or searching forums you can generate the code online using the radio serial number.
- Start by finding the serial number. It is always present on the unit itself, and in some cases it can be visible on the Grand Caravan's display.
- Enter it into the generator above, and our system will identify the correct 2020 Grand Caravan unlock code.
- After receiving your code, type it in using Grand Caravan's radio controls to unlock the system successfully.
- The entire process takes only a few minutes and requires no VIN, documents, or technical knowledge.
Entering the Radio Security Code
When you obtain 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 Grand 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.
Step-by-Step - The Correct Way to Enter It
Entering the code on the 2020 Chrysler Grand Caravan Uconnect 8.4":
- Turn ignition to ON. Screen shows "ENTER CODE".
- Tap each digit of your 4-digit code.
- Radio auto-confirms after the 4th digit. No confirm button needed.
3 wrong entries cause a 60-minute lockout. Keep ignition ON. Switching off restarts the timer.
Step-by-Step Code Input Guide
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.
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, 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 and confirm with the on-screen OK/Enter button. On the base RES head unit, press the numbered preset buttons (1-6) in sequence and confirm with the tune/menu knob or labelled enter button as prompted on the display.
If a wrong code was entered. If WAIT or 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.
Can't Locate Your Unit's Serial Number? Follow The Steps Below for Chrysler Grand Caravan 2020
The starting step is locating the radio serial.
Most people assume the code depends on the Chrysler 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 an aftermarket radio, the VIN or other Chrysler-specific data wouldn't help.
Depending on the radio version used, you may be able to retrieve the serial directly from the screen or by looking at the label on the radio chassis.
Identify Your 2020 Grand Caravan's Factory Radio
2020 was the final model year of the RT-platform 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. The base RES (Media Center 130) is a non-touchscreen AM/FM/CD radio with a small monochrome single-line display, hard preset buttons and rotary tune/volume knobs - no screen graphics, no NAV button, no factory Bluetooth, and the most common fit out the door. The volume RBZ (430 MyGIG, 6.5" touchscreen, no nav) has a glossy black bezel, 6.5-inch color touchscreen and hard buttons for Radio, Media, Controls, More and Phone flanking the screen, with no NAV soft key on the home page because it has no navigation hardware - the dominant touchscreen variant by far. The top-tier RHB (430N MyGIG, 6.5" with Garmin nav) is externally identical to RBZ - same Mitsubishi-built 6.5-inch screen, same bezel, same hard keys; the on-screen tells are a NAV soft key on the home menu, a Garmin splash logo at startup and a 28GB hard drive for stored music - a rare option even by 2020. Optional rear-seat DVD entertainment remained available as an 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.
Find Your S/N on the Radio Display
Try the following for your 2020 Chrysler Grand Caravan:
The 2020 Chrysler Grand Caravan — the iconic American family hauler with Stow 'n Go seating — features the Uconnect 8.4" Classic (RA3). The Grand Caravan's center stack positions the climate controls right underneath the 8.4" touchscreen, providing straightforward access to Dealer Mode.
Press and hold Climate Up, Climate Down, and Front Defrost simultaneously for 5 seconds with ignition in ACC or ON. Dealer Mode opens. Go to: System Info → Radio Part Info → Serial Number.
Grand Caravan's Hardware Label Method
If the serial number cannot be accessed on-screen, use the removal method.
Most Chrysler Grand Caravan OEM radios include a label with the serial number printed on the housing.
Process details:
- Remove key from ignition.
- Gently detach surrounding mounting frame.
- Release clips holding the radio.
- Pull forward to inspect the label.
If Dealer Mode is unavailable on the 2020 Chrysler Grand Caravan, remove the RA3 from the Grand Caravan's family-oriented center stack.
- Remove the center stack bezel with a plastic trim tool.
- Remove the 4 Phillips mounting screws.
- Pull the unit forward to read the serial label on the side or back of the chassis.
The Grand Caravan's no-nonsense center stack makes removal fairly easy.
Serial Number on the Unit
The factory head units offered on the 2020 Grand Caravan - the final model year before the RT-platform 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.
Removal overview. Ease the centre dash bezel forward at the lower edge using a plastic pry tool and work up the sides; on the post-2011 Grand 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.
Where the serial sits. 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.
Tips. Photograph the label up close and double-check ambiguous characters such as 0/O and 1/I before submitting the serial.

Typical Serial Number Formats for 2020 Grand Caravan Radios
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 TM9 alongside other T-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.
