2019 Ram 5500 Radio Code: How to Get It?

Where to Find the Serial Number on your 5500

The first part is to find and write down the radio's serial number.

Depending on the radio unit installed in your 2019 5500, the serial can be found either through the display menu or by pulling the unit out and checking the label on the radio itself.

Below are the most common methods to identify your serial quickly.

Factory Radios on the 2019 Ram 5500

The 2019 Ram 5500 - part of the all-new fifth-generation DT HD platform launched for 2019 with a redesigned dash - shipped with the Uconnect 4 family of head units. Across the trim ladder (Tradesman, Big Horn/Lone Star, Laramie, Power Wagon on the 2500, Limited and on Chassis Cab models Tradesman, SLT, Laramie and Limited) several screen sizes were available.

Uconnect 3 / Uconnect 4 (sales code UAG) - 5-inch base touchscreen. Standard on Tradesman and base Chassis Cab. Visual ID: small 5-inch screen mounted high in the centre stack with conventional climate controls below; Bluetooth audio and basic media support.
Uconnect 4C 8.4 NAV (sales code UAQ, Canadian equivalent UCQ) - 8.4-inch touchscreen with built-in GPS navigation, Apple CarPlay and Android Auto (wired). Standard or part of the upgrade group on most mid trims. Visual ID: 8.4-inch landscape glass dropped into the upper centre stack with a dedicated NAV/Map tile on the home screen.
Uconnect 4C NAV 12-inch (sales code UAX) - 12-inch portrait touchscreen with split-screen capability, GPS navigation, Apple CarPlay and Android Auto (wired). Optional on Laramie, standard on Limited. Visual ID: large vertical 12-inch glass that fills the upper centre stack and can show two apps stacked on top of one another.

Quick test for the 2019 5500: 5-inch screen means UAG, 8.4-inch landscape means UAQ/UCQ, and a tall 12-inch portrait screen means UAX.

Fast Serial Lookup Using Radio Controls

Try the following for your 2019 Ram 5500:

The 2019 Ram 5500 largest-class chassis cab features the Uconnect 4C (RA4) 8.4" touchscreen fitted in the work cab. The serial number is retrievable via Dealer Mode:

Turn ignition to ACC or ON.
Press the bottom-left and bottom-right corners of the physical screen bezel (plastic frame, not glass) simultaneously 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 2019 5500 units after a software update. If the bezel press fails, physical removal is required.

Display-Based Serial Number Retrieval

The 2019 Ram 5500 ships with Uconnect 4 hardware (8.4-inch UAQ/UCQ landscape and the optional 12-inch UAX portrait), and both touchscreens respond to a hidden dealer/diagnostic shortcut that prints the radio serial on screen - no head-unit removal required.

Switch the ignition to RUN/ACC and let the Uconnect interface finish booting.
Press and hold the driver-side temperature UP button, the driver-side temperature DOWN button and the front DEFROST button together for roughly 5-10 seconds until the dealer/engineering screen opens.
If the climate-button shortcut does nothing, press and hold the bottom-left and bottom-right corners of the screen at the same time for about 5-10 seconds.
Once inside the diagnostic interface, browse to the radio/system info section to read the serial number printed on screen.
Photograph the screen so each character can be transcribed without typos - treat 0/O, 1/I and B/8 carefully.

The 5-inch UAG base radio is much less consistent with the on-screen shortcut, so for that unit fall back on the chassis-label method described below.

Serial Number on the Unit

If the serial number cannot be accessed on-screen, use the hardware method.

Most Ram 5500 original radios include a label with the serial number printed on the housing.

Step-by-Step Approach:

Turn off the vehicle.
Remove the dashboard frame surrounding the radio.
Release the mounting bolts.
Pull the unit outward to access the label.

The serial number is usually located near the printed code.

If Dealer Mode is not accessible on your 2019 Ram 5500, the radio needs to be removed to access the serial label:

Turn off the vehicle.
Pry off the surrounding bezel with a plastic pry tool. The 5500's commercial cab trim uses friction clips – start at the bottom.
Unscrew the mounting screws (Torx T20 or T25).
Pull the unit forward to read the serial label on the side or top of the chassis.

Wiring can remain connected while you note the serial.

View Serial by Pulling Out the Radio Unit

The factory radio in the 2019 Ram 5500 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 (2019 Ram 5500 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 5500 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 2019 Ram 5500 Uconnect 4C (RA4) serial number formats:

T00AM – Harman Uconnect 4C (most common prefix)
T00BE – Continental version
T0MYD – Newer Harman production (2020+)

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

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

Typical Serial Number Formats for 2019 Ram 5500 Radios

The factory radios fitted to the 2019 Ram 5500 use the standard Mopar/Uconnect head-unit serial style. The exact prefix depends on the Uconnect tier shipped with the truck and the supplier (Mitsubishi Electric, Continental, Harman or Visteon) that built the unit, so any prefix list found online should be treated as a guide rather than a strict rule.

Uconnect 4C 8.4 (UAQ / UCQ) and 12-inch UAX

Typically a 14-character alphanumeric string printed on the chassis label.
Commonly begins with T - frequent prefixes include T00AM, TM9 and TQ1 - or with A2C on Continental-built variants.
Usually a continuous run of letters and digits with no dashes or spaces.

Uconnect 3 / Uconnect 4 5-inch (UAG)

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.
Always copy the serial exactly as printed and avoid guessing characters that look unclear.

Unlock Your 2019 Ram 5500 Radio in Minutes - How It Works

Car radios use security codes dependent on the radio unit itself instead of the model or production year.

Our lookup service works by matching your Ram 5500 radio's serial number.
When you input the serial into the generator, the system identifies the radio family and generates the code that you need.
Use the code to unlock the radio immediately.
This approach saves time compared to traditional methods for 2019 Ram 5500.

Inputting the Security Code

Now that you've generated 2019 Ram 5500 unlock code from the S/N, you're ready to reactivate the radio.

Some drivers get stuck at this stage because input methods can look different across radio versions, but it's usually easy.

When the radio shows ENTER CODE, it means the unit is waiting for the correct numbers.

Correct Entering Process

Entering the unlock code on the 2019 Ram 5500's Uconnect 4C:

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

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

Step-by-Step Code Input Guide

Once the unlock code has been retrieved, the 2019 Ram 5500 Uconnect 4 head unit can be unlocked at the dash without a scan tool or dealer visit.

Limited Attempt Warning: Mopar/Uconnect head units only accept three incorrect tries before the radio enters a WAIT state. If the lockout activates, the radio must remain powered with the ignition in RUN for roughly 30 continuous minutes (the vehicle may be driven during this time) before another attempt is allowed. Repeated wrong-code lockouts can extend the wait significantly, so confirm every 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, Please enter Anti-Theft Code, or a similar prompt.
On the Uconnect 4C 8.4 (UAQ/UCQ) and 12-inch UAX, tap the on-screen number pad to enter each digit and confirm with the OK/Enter touch button.
On the 5-inch UAG base radio, use the numbered preset buttons (1-0) to key each digit of the code in sequence; confirm with the OK/Enter soft key if the unit prompts for it.
If WAIT appears after wrong attempts, leave the radio powered with the ignition in RUN for the documented cool-down period before trying the correct code again.

If a correct-looking code is rejected, double-check the radio serial that was used to retrieve the code, and that the VIN tied to the code matches the truck the radio is currently installed in - a VIN mismatch is the most common reason an apparently correct code is refused.

Understanding Unlock Issues with Your 5500

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

A rejected code on the Ram 5500's Uconnect 4C typically indicates a serial number error. The RA4 label has both the serial (T00AM, T00BE, or T0MYD, 14 chars) and the part number (P05... or 68...) — only the serial generates the code.

Heavy-duty labels may be hard to read. Take a photo and zoom in to verify each character. Reach out for a free re-check if needed.

The Uconnect 4C serial on the Ram 5500 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.

Ignore the part number (P05... or 68...) on the same label.

The Ram 5500's Uconnect 4C uses touchscreen-only code entry — press each digit on the on-screen number pad. No physical preset buttons are involved. The radio auto-unlocks after the last digit.

The Ram 5500'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. Turning off restarts the countdown. Fleet-managed vehicles must complete the full wait without interruption.

Why Did the Radio Lock and Ask for a Code?

The Ram 5500's Uconnect 4C activates anti-theft after the battery is disconnected or replaced. Ram 5500 commercial operators encounter this primarily due to:

Battery replacement during service — primary cause. 5500s carry heavy electrical loads that wear batteries faster.
Commercial upfit electrical work — these trucks get heavily upfitted which frequently involves battery disconnects, activating the anti-theft.
Blown fuse — common in heavily upfitted vehicles.
Buying fleet-retired without the code.

The code is derived from the radio's serial number — not the VIN.
