How Our Radio Code Generator Works for 2022 Ram 5500
Vehicle radios use anti-theft codes tied to the radio unit itself instead of the model or production year.
- The generator identifies your Ram radio via serial-based verification.
- Once the serial number is submitted, the system identifies the radio family and generates the code that you need.
- Simply input the digits into the 5500 stereo.
- Compared to Ram dealer retrieval, this method is faster and more convenient.
Finding the Radio S/N for Ram
The first part is to locate the radio's serial number.
Depending on the radio unit installed in your 2022 5500, the serial can usually be found either through the display menu or by checking the label on the radio itself.
Follow the steps below to identify your serial quickly.
Radios Offered in the 2022 Ram 5500
For 2022 the Ram 5500 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.
Access the Serial Number via the Radio Display
Try the following for your 2022 Ram 5500:
The 2022 Ram 5500 largest-class chassis cab features the Uconnect 4C (RA4) 8.4" touchscreen in the commercial cab. 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, not glass) simultaneously for 5 seconds.
- Dealer Mode opens on the display.
- Navigate to: System Info → Radio Part Info → Serial Number.
Note Dealer Mode may be restricted on some 2022 5500 units after a software update. If the bezel press fails, physical removal is the fallback.
Releasing the Radio to See the S/N on the Tag
If the serial does not appear in menu, the next step is checking the radio itself.
Many Ram radios require physical access to the ID label attached to the unit.
Common approach:
- Start by completely powering down the engine - pull the key out.
- Then remove the dashboard bezel.
- Next, release the mounting points and slide the radio forward.
- Look for a printed tag showing the serial number.
If Dealer Mode is not accessible on your 2022 Ram 5500, the radio must be removed to access the serial label:
- Turn off the vehicle.
- Pry off the center stack trim with a plastic pry tool. The 5500's commercial cab trim has friction clips – start at the bottom.
- Remove the mounting screws (Torx T20 or T25).
- Slide the unit out to read the serial label on the side or top of the chassis.
Cables can remain connected while you read the serial.
Releasing the Unit to Access the S/N on the Tag
The factory radio in the 2022 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 (2022 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.

Typical Radio Serial Prefixes and Formats
The 2022 Ram 5500 Uconnect 4C (RA4) serial number formats:
T00AM– Harman Uconnect 4C (most common prefix)T00BE– Continental variantT0MYD– 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 not the same as the part number (P05064... or 68...). Only the 14-char serial generates the code.
How Serial Numbers Usually Look on These Ram 5500 Radios
The factory radios fitted to the 2022 Ram 5500 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.
Code Entry Instructions
Once you have the serial number and generated the unlock code, the last part is entering it into your radio.
Ram original head units display a locked screen when ready for input.
The process is simple, but button layouts and confirmation methods may change depending on the radio version installed in your 5500.
Entering Process
Entering the unlock code on the 2022 Ram 5500's Uconnect 4C:
- The 8.4" display shows "ENTER CODE" after a battery event.
- Use the touchscreen keypad to enter each digit of the 4-digit code.
- The radio auto-unlocks after the 4th digit – no confirm step needed.
Lockout Warning: 3 wrong attempts = 60-minute lockout. Keep ignition ON. Cycling the ignition restarts the wait.
Why Did the Radio Lock and Ask for a Code?
The Ram 5500's Uconnect 4C activates anti-theft after any power interruption. Ram 5500 commercial operators see this primarily due to:
- Battery replacement during service — primary cause. 5500s run significant accessory loads that wear batteries faster.
- Commercial upfit electrical work — these trucks get heavily upfitted which often requires disconnecting the battery, activating the anti-theft.
- A failed radio fuse — common in heavily upfitted vehicles.
- Buying pre-owned without a known unlock code.
The code is derived from the radio's serial number — not the VIN.
Understanding Unlock Issues with Your 5500
The Ram 5500's Uconnect 4C enters lockout after 3 wrong entries. The screen continues to display "ENTER CODE" but ignores all input.
To reset: Keep ignition ON for a full 60 minutes. Turning off resets the timer. Fleet-managed vehicles must complete the full wait without interruption.
The Uconnect 4C serial on the Ram 5500 can be read 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.
Do not use the part number (P05... or 68...) on the same label.
The Ram 5500's Uconnect 4C uses touchscreen-only code entry — tap each digit on the virtual number pad. No physical preset buttons are used. The radio auto-unlocks after the last digit.
No code prompt means the Uconnect 4C isn't locked. Force the lock: pull the radio fuse and reinsert it, then turn ignition ON. The prompt appears on startup.
A rejected code on the Ram 5500's Uconnect 4C typically indicates a serial number error. 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.
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.
