Understanding the Radio Serial Number and How to Locate It on 2016 Caravan
Very important fact to know is that factory radios use a unique serial number to identify each unitindividually.
The security system matches the code directly to the serial.
Different from car-specific data like VIN or registration info, it is not determined by the model or production year, so you'll be able to generate it even if you have an aftermarket radio.
Depending on the maker and radio installed in your Dodge Caravan, the access method is different.
Here are the most reliable ways to find it.
Radios Offered in the 2016 Caravan
For 2016 the Grand Caravan still shipped with the same trio of legacy Mopar head units - the Uconnect 8.4 RA3/RA4 platform that arrived elsewhere in the Chrysler/Dodge range never came to this minivan. The base RES (Media Center 130) AM/FM/CD radio is non-touchscreen with a small one-line display and physical hard preset buttons; no NAV key, no large screen. The volume option RBZ (430 MyGIG) has a 6.5-inch color touchscreen flanked by hard keys and no NAV soft key (because it has no navigation). The top-tier RHB (430N MyGIG) looks identical to RBZ but adds Garmin navigation - tell them apart by the NAV soft key on the home menu and the Garmin boot logo. The optional overhead rear-seat DVD entertainment system - 9-inch flip-down headliner screen with separate DVD player in the lower dash - was still on the option list. RBZ remained the dominant touchscreen fit; RES was standard on the cheapest trims.
View Your Serial Number via the Radio Screen
The method for 2016 Dodge Caravan is this:
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 it by Pulling Out the Unit
If the serial number cannot be accessed through menu, use the hardware method.
Most Dodge Caravan OEM radios include a sticker with the serial number printed on the housing.
The process:
- Ensure the ignition is off.
- Carefully remove surrounding mounting frame.
- Remove fasteners holding the radio.
- Move slightly to inspect the label.
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.
Manufacturer Label Inspection
The factory head units offered on the 2016 Grand Caravan - typically the RES single-CD radio, the RBZ MyGIG 430 (6.5-inch touchscreen), the RHB MyGIG 430N (6.5-inch touchscreen with navigation), and the optional REZ rear-seat DVD entertainment module - all keep their serial on a printed chassis label. These legacy units do not expose the serial through the screen, so the head unit has to come out for the sticker to 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. The post-2011 Caravan dash was reworked to make the head unit easier to service. Ease the centre stack bezel forward at the lower edge using a plastic pry tool and work up the sides - on this body it is held in by four friction clips with no visible screws on the bezel itself. With the four clips released, lay the bezel on a soft cloth (it does not need to be unplugged from any harness to do the job). 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 radio 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 in good light and double-check ambiguous characters such as 0/O and 1/I before submitting the serial.

What a Valid Serial Number Looks Like
The 2016 Dodge Caravan's Uconnect 8.4" (RA3) uses these common serial formats:
T00AM– Harman VP2 Uconnect (most common format)T00BE– Continental-made versionTM9– Older Harman units
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.
Typical Serial Number Examples for 2016 Caravan
The factory radios fitted to the 2016 Grand Caravan are legacy Mopar head units rather than the later Uconnect 8.4 platform, so the prefix on the chassis label depends on 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 the 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.
Got the Code? Here's How to Enter It
After generating the correct unlock code based on the serial number, you can restore normal functionality by entering it into the unit.
The code entry process depends on the head unit design, but most 2016 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.
Detailed Entering Instructions for Caravan 2016
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.
- The radio auto-confirms after the 4th digit — nothing else is required.
Lockout: 3 wrong entries = 60-minute lockout. Leave ignition ON. Turning it off resets the timer.
Entering Process Explained
Once the unlock code has been retrieved for a 2016 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.
How 2016 Dodge Caravan Radio Code Lookup Works
To get the code, you'll take only a few easy steps.
- Find the radio's serial number - this is the only information required by our side.
Unlike dealership lookup, no VIN is needed. - Enter the serial number into our generator above.
Our system checks it against a database of supported radios and automatically finds the matching anti-theft code. - In most cases, the code appears instantly on the screen after payment and is also sent to your email , just in case.
If manual verification is required (rare situations), you'll be notified before checkout. - Once you get it, just enter it into the radio to restore the functionality.
Why Did the Radio Lock and Ask for a Code?
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.
Caravan 2016 Common Radio Problems
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.
