How to find Ram 4500 2022 radio serial number

Finding the Radio S/N for Ram

The important fact to know is that factory radios use a specific S/N to identify each unitindividually.

The security system matches the code directly to this serial.

Different from vehicle-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 4500, the access method varies.

These are the most reliable ways to find it.

Radios Offered in the 2022 Ram 4500

For 2022 the Ram 4500 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.

Quick Method: Find the Serial Number on the Screen

Try the following for your 2022 Ram 4500:

The 2022 Ram 4500 severe-duty chassis truck is equipped with the Uconnect 4C (RA4) 8.4" touchscreen fitted in the work cab interior. The serial number is accessible via Dealer Mode:

  1. Turn ignition to ACC or ON.
  2. Press the bottom-left and bottom-right corners of the physical screen bezel (plastic frame, not glass) simultaneously for 5 seconds.
  3. Dealer Mode opens on the display.
  4. Navigate to: System Info → Radio Part Info → Serial Number.

Note Dealer Mode could be disabled on some 2022 4500 units after a software update. If the bezel press fails, physical removal is the fallback.

View the S/N by Pulling Out the Radio

If the serial does not appear on screen, the next step is checking the radio itself.

Many Ram radios require physical access to the ID label attached to the unit.

Usual approach:

  1. Start by completely shutting off the engine - pull the key out.
  2. Then remove the radio surround.
  3. Next, loosen the mounting points and pull the radio forward.
  4. Look for a printed tag showing the serial number.

If Dealer Mode is unavailable on your 2022 Ram 4500, the radio must be removed to read the serial label:

  1. Turn off the vehicle.
  2. Pry off the center stack trim with a plastic pry tool. The 4500's work cab trim uses friction clips – work from the lower edge to release.
  3. Unscrew the mounting screws (Torx T20 or T25).
  4. Pull the unit out to access the serial label on the side or top of the chassis.

Wiring don't need to be unplugged while you note the serial.

Releasing the Unit to Access the S/N on the Tag

The factory radio in the 2022 Ram 4500 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 4500 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 4500 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.

These are the Common Serial Formats

The 2022 Ram 4500 Uconnect 4C (RA4) serial number formats:

  • T00AM – Harman Uconnect 4C (most common prefix)
  • T00BE – Continental version
  • T0MYD – Updated Harman production (later models)

Radio designation: RA4 (Uconnect 4C, 8.4"). Serial: 14 characters. The Ram 4500 chassis cab shares the same RA4 platform as the Ram 3500 and 5500.

Important The serial number is different from the part number (P05064... or 68...). Only the 14-char serial generates the code.

How Serial Numbers Usually Look on These Ram 4500 Radios

The factory radios fitted to the 2022 Ram 4500 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 example T00-prefixed Mitsubishi Electric builds) or with A2C on 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.

Radio Code Input Guide

Now that you've found the radio serial and retrieved the unlock code, the last part is entering it into your radio.

Ram factory radios display a ENTER CODE message when ready for input.

The process is usually quick, but button layouts and confirmation methods may change depending on the radio version installed in your 4500.

In-depth Input Instructions for 4500 2022

Entering the unlock code on the 2022 Ram 4500's Uconnect 4C:

  1. The 8.4" screen presents "ENTER CODE" after a battery event.
  2. Tap the touchscreen keypad to enter each digit of the 4-digit code.
  3. The radio auto-unlocks after the 4th digit – nothing else needed.

Lockout Warning: 3 wrong attempts = 60-minute lockout. Keep ignition ON. Cycling the ignition restarts the wait.

Locked 4500 Radio? Here's Exactly How to Get the Code

Vehicle radios use security codes tied to the radio unit itself instead of the vehicle model or production year.

  • The system uses the 4500's radio serial to retrieve the unlock code.
  • After entering the serial into the form above, the system identifies the radio family 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.

Understanding Unlock Issues with Your 4500

The Ram 4500's Uconnect 4C enters lockout after 3 wrong entries. The screen keeps showing "ENTER CODE" but ignores all input.

To reset: Keep ignition ON for a full 60 minutes. Turning off resets the timer. Commercial fleet vehicles must complete the full wait without interruption.

The Uconnect 4C serial on the Ram 4500 is accessible via Dealer Mode (System Info → Radio Part Info → Serial Number) or on the barcode sticker on the radio chassis after removal. Serial: 14 chars starting with T00AM, T00BE, or T0MYD.

Do not use the part number (P05... or 68...) on the same label.

A rejected code on the Ram 4500's Uconnect 4C usually means the wrong serial was submitted. The RA4 label shows the serial (T00AM, T00BE, or T0MYD, 14 chars) and the part number (P05... or 68...) — the serial alone generates the code.

Commercial-use labels can be worn or dusty. Wipe down the label or photograph it. Reach out for a free re-check if needed.

The Ram 4500'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 unlocks after the 4th digit.

No code prompt means the Uconnect 4C isn't locked. To trigger the code screen: briefly disconnect the battery, then turn ignition ON. The prompt shows on startup.

Why Is the Radio Asking for a Code?

The Ram 4500's Uconnect 4C activates anti-theft after any power interruption. Commercial chassis cab owners encounter this most often because of:

  • Battery replacement during service — primary cause. Commercial vehicles undergo frequent service and battery changes are common.
  • Upfit electrical work — these trucks get bodies and equipment added which requires electrical disconnects, triggering the lock.
  • A failed radio fuse — frequent after commercial electrical work.
  • Buying fleet-retired without a known unlock code.

The code is tied to the radio's serial number — not the VIN.
