2022 Ram 3500 Radio Models We Support
The following factory radios shipped in the 2022 Ram 3500. Open yours to check how to identify it and how the code is retrieved.
How to Find the Serial Number on Your 2022 Ram 3500 Radio?
The important thing to know is that factory radios use a specific serial number to identify each unit.
Your anti-theft system links the code directly to this serial.
Different from car-specific data like VIN or registration information, 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 Ram 3500, the access method varies.
Here are the most reliable ways to locate it.
Radios Offered in the 2022 Ram 3500
For 2022 the Ram 3500 runs the Uconnect 5 infotainment platform as standard across SLT and above (with Uconnect 4 retained on the very base Tradesman/base Chassis Cab in some markets). Uconnect 5 introduced wireless Apple CarPlay and Android Auto, five user profiles and a much faster processor compared with the Uconnect 4 hardware it replaced.
- Uconnect 3 / Uconnect 4 (sales code
UAG) - 5-inch base touchscreen, retained on the lowest Tradesman/base Chassis Cab build only. Visual ID: small 5-inch screen with conventional climate controls below. - Uconnect 5 with 8.4-inch display (sales code
UBL) - 8.4-inch landscape touchscreen with wireless Apple CarPlay and Android Auto, optional GPS navigation. Visual ID: 8.4-inch glass with the Uconnect 5 home grid (multiple user profiles, large widgets) instead of the older Uconnect 4 tile layout. - Uconnect 5 NAV with 12-inch display (sales code
UBQ) - 12-inch portrait touchscreen with built-in GPS, wireless Apple CarPlay and Android Auto. Standard on Limited and optional/standard on Laramie depending on the build. Visual ID: large vertical 12-inch glass with split-screen and the Uconnect 5 interface.
Quick test for 2022: a 5-inch screen with the older Uconnect interface means UAG, an 8.4-inch landscape screen with the new Uconnect 5 home grid means UBL, and a tall 12-inch portrait screen running Uconnect 5 means UBQ.
Find Your Serial Number via the Radio Screen
These are the steps you need to follow for 2022 Ram 3500:
The 2022 Ram 3500 1-ton heavy-duty truck is equipped with the Uconnect 4C (RA4) 8.4" touchscreen in the HD's center stack. The serial number is accessible via Dealer Mode:
- Turn ignition to ACC or ON.
- Press the bottom-left and bottom-right corners of the physical screen bezel (plastic frame) at the same time for 5 seconds.
- Dealer Mode appears on the display.
- Select: System Info → Radio Part Info → Serial Number.
Note Dealer Mode may be restricted on some 2022 Ram 3500 units after a software update. If so, physical removal is required.
Pulling Out the Radio Unit to Access the S/N on the Tag
If the serial does not appear on display, the next step is checking the radio itself.
Many Ram 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, loosen the mounting points and pull the radio forward.
- Look for a printed tag showing the serial number.
If Dealer Mode is unavailable on your 2022 Ram 3500, the radio needs to be removed to access the serial label:
- Turn off the vehicle.
- Pry off the center stack trim with a plastic pry tool. The 3500 HD's center stack can include heavy-duty trim needing steady pressure to release the friction clips.
- Remove the mounting screws (Torx T20 or T25) securing the radio.
- Pull the unit forward to access the serial on the top surface of the chassis.
Wiring don't need to be unplugged while you read the serial.
Releasing the Unit to Access the S/N on the Tag
The factory radio in the 2022 Ram 3500 also carries a printed barcode/sticker label on the chassis. On the fifth-generation DT HD dash the head unit (especially the 12-inch portrait UAX/UBQ) sits inside a wide centre-stack bezel that integrates the screen surround with adjacent climate and storage trim, so the work needs to be done methodically.
- Safety first: turn the ignition fully off, remove the key fob from the cabin, disconnect the negative battery terminal and wait at least 10-15 minutes before touching wiring so the SRS/airbag capacitors can discharge. Avoid yellow airbag/SRS connectors entirely and use plastic trim tools so nothing shorts or breaks.
- Tools you will need: plastic trim/panel removal kit, T20 Torx bit, Phillips #2 screwdriver, 7mm socket and short extension, flashlight, clean microfibre to rest the bezel on.
- Removal overview (2022 Ram 3500 dash): lift the rubber beauty pad on top of the centre stack to expose two T20 Torx screws and remove them; lift the rubber mat in the small cubby behind the 120V outlet to expose a third T20 Torx screw and remove that as well. With those three screws out, pull the centre-stack bezel rearward starting at the lower edge to release the spring clips around its perimeter. The bezel carries the hazard/HVAC switches, so unclip those harnesses before setting it aside on a clean cloth. Remove the four 7mm screws securing the radio cage to the dash support bracket, then slide the head unit straight rearward and disconnect the antenna lead and the multi-pin power/data connectors at the rear.
- Where the serial sits: the serial number is printed on a barcode/sticker label on the top or one side of the radio chassis, alongside the part number and supplier markings. Photograph the label up close and double-check ambiguous characters such as 0/O, 1/I and B/8 before submitting the value.
- Tips and professional advice: the 12-inch UAX/UBQ portrait head unit on the 3500 is deeply integrated into the wider centre-stack trim and shares hardware with the climate cluster, hazard switch and 120V outlet bezel - if the trim resists, stop and double-check for hidden screws rather than pulling harder. Owners who are not comfortable working around airbag wiring or releasing the wide integrated bezel should have a professional installer or dealer technician remove the unit instead; an experienced shop typically completes this in well under an hour.

Common Serial Number Structures
The 2022 Ram 3500 Uconnect 4C (RA4) serial number formats:
T00AM– Harman Uconnect 4C (primary prefix)T00BE– Continental variantT0MYD– Newer Harman production (2020+)
Radio designation: RA4 (Uconnect 4C, 8.4"). Serial: 14 characters. The Ram 3500 shares the same RA4 platform as the 2500 HD.
Important Do not mix up the serial with the part number (P05064... or 68...). Only the 14-char serial generates the code.
How Serial Numbers Usually Look on These Ram 3500 Radios
The factory radios fitted to the 2022 Ram 3500 are predominantly Uconnect 5 head units (with Uconnect 4 retained on the base 5-inch UAG only). The serial style follows the standard Mopar/Uconnect convention, with the exact prefix driven by the supplier and software build of the specific unit, so any pattern below should be treated as a guide rather than a strict rule.
Uconnect 5 8.4-inch (UBL) and 12-inch (UBQ)
- Typically a 14-character alphanumeric string printed on the chassis barcode label.
- Often begins with
T(for exampleT00-prefixed Mitsubishi Electric builds) or withA2Con Continental-built modules. - Printed as a continuous run of letters and digits, with no spaces or dashes.
Uconnect 3 / Uconnect 4 5-inch (UAG, base only)
- Usually carries a Mopar/Visteon or Panasonic-style serial on the chassis sticker, so the printed label on the unit itself is the authoritative reference.
- Copy the serial exactly as printed and avoid guessing characters that look unclear.
How to Enter the Radio Code
After generating the correct unlock code based on the serial number, you can restore default functionality by entering it into the unit.
The code entry process depends on the radio interface, but most 2022 3500 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 CODE displayed on screen.
The Correct Way to Enter It
To input the unlock code on the 2022 Ram 3500's Uconnect 4C:
- The 8.4" screen shows "ENTER CODE" after a battery event.
- Use the touchscreen keypad to enter each digit of the 4-digit code.
- The radio restores after the 4th digit – nothing else needed.
Lockout Warning: 3 wrong attempts = 60-minute lockout. Keep ignition ON. Turning off the ignition resets the timer.
How to Unlock a Ram 3500 Radio After Power Loss
Vehicle radios use anti-theft codes dependent on the radio unit itself rather than the model or production year.
- The system uses the 3500's radio serial to retrieve the unlock code.
- Once the serial number is submitted, the system identifies the radio unit and retrieves the corresponding code.
- Use the code to unlock the radio immediately.
- Compared to Ram dealer retrieval, this method is faster and more convenient.
What Caused the Radio to Lock?
The Ram 3500's Uconnect 4C locks automatically after the battery is disconnected or replaced. 1-ton Ram 3500 owners see this primarily due to:
- Battery replacement — primary cause. 1-ton trucks have higher electrical loads from trailers and accessories, making battery changes more frequent.
- Upfit and accessory work — 3500 owners who add fifth-wheel prep, gooseneck hitches, or commercial upfits who disconnect the battery will encounter this.
- Blown fuse — common after heavy electrical work.
- Buying pre-owned without the code.
The code is tied to the radio's serial number — not the VIN.
3500 2022 Common Radio Problems
The Uconnect 4C serial on the Ram 3500 is accessible via Dealer Mode (System Info → Radio Part Info → Serial Number) or on the physical label on the radio chassis after removal. Serial: 14 chars starting with T00AM, T00BE, or T0MYD.
Ignore the part number (P05... or 68...) on the same label.
The Ram 3500's Uconnect 4C enters lockout after 3 wrong entries. The screen keeps showing "ENTER CODE" but blocks all input.
To reset: Keep ignition ON for a full 60 minutes. Any power interruption restarts the countdown. High-use work trucks must complete the full wait in one session.
A rejected code on the Ram 3500's Uconnect 4C typically indicates the wrong serial was submitted. The RA4 label has the serial (T00AM, T00BE, or T0MYD, 14 chars) and the part number (P05... or 68...) — only the serial generates the code.
Work truck labels can be dirty in heavy-use environments. Clean the label or photograph it. Contact support for a free re-check if needed.
The Ram 3500's Uconnect 4C uses touchscreen-only code entry — press each digit on the on-screen number pad. No physical preset buttons are used. The radio auto-unlocks after the 4th digit.
No code prompt means the Uconnect 4C isn't activated. Force the lock: briefly disconnect the battery, then turn ignition ON. The prompt shows on startup.
