Which radio unit could your 2017 Ram 5500 use?
Every link below opens a radio model fitted at the factory to the 2017 Ram 5500. Compare the display and faceplate to pick the right one, then confirm the serial prefix.
Why Did the Radio Lock and Ask for a Code?
Uconnect activates anti-theft after a battery disconnect or replacement. Commercial vehicles see this more than most because battery work is routine in construction and commercial fleets.
Common causes:
- Battery replacement — the most frequent trigger
- Failed fuse — common after upfit installation
- Buying the truck fleet without any unlock documentation
- Battery completely discharged from storage
The code is derived from the radio's serial number — not the truck's VIN.
Can't Find Your Unit's Serial Number? Follow These Steps for Ram 5500 2017
The initial step is to find and write down the radio's serial num.
Based on the head unit type installed in your 2017 5500, the S/N can usually be accessed either through the screen menu or by checking the label on the radio itself.
Below are the most common methods to identify your serial the right way.
Which Head Unit Is in Your 2017 Ram 5500?
The 2017 Ram 5500 keeps the same four Uconnect head units that have been on offer since 2013. There are no major hardware changes to the radio fleet for this model year - the new 4C generation with Apple CarPlay/Android Auto does not arrive on the HD trucks until later.
- Uconnect 3.0 / RA1 - base AM/FM/CD radio on fleet Tradesman builds. Small monochrome strip display, hard knobs, no touchscreen.
- Uconnect 5.0 / RA2 - 5-inch colour touchscreen, common on Tradesman and entry SLT. AM/FM, Bluetooth, USB and aux. No CD slot, no NAV button.
- Uconnect 8.4 / RA3 - 8.4-inch landscape touchscreen, optional on SLT and standard on Laramie. Capacitive shortcut row across the bottom of the display, no Nav tile on the home screen.
- Uconnect 8.4N / RA4 - same 8.4-inch hardware as RA3 with the Garmin nav engine enabled. A Nav tile sits on the home screen and a SiriusXM Traffic/Travel Link badge appears at startup. Standard on Longhorn, optional on most other trims.
Quick tell: no screen = RA1; 5-inch screen = RA2; 8.4-inch screen with no Nav tile = RA3; 8.4-inch screen with a Nav tile = RA4. The sales code is printed on the label on top of the radio chassis.
Accessing the Serial Number Through the Radio Menu
These are the steps you need to follow for 2017 Ram 5500:
The 2017 Ram 5500 heavy-duty truck features the same Uconnect infotainment system as the Ram 1500. Based on trim level, you'll find a Uconnect 3.0/5.0" (base trims) or Uconnect 8.4" (premium trims).
For 8.4" Uconnect (RA3): Press and hold the Climate Up, Climate Down, and Front Defrost buttons together for 5 seconds to launch Dealer Mode. Then go to: System Info → Radio Part Info → Serial Number.
For base Uconnect: Dealer Mode is not supported. Removing the radio is required to access the serial label.
Get the Serial From the Touchscreen
For 2017 Ram 5500 trucks fitted with the 8.4-inch Uconnect, you can usually pull the serial number directly off the screen using a hidden dealer/diagnostic menu. This is much faster than removing the radio. The smaller RA1 and RA2 head units do not have a reliably documented on-screen serial readout for this generation.
Uconnect 8.4 (RA3) and Uconnect 8.4N (RA4)
- Place the ignition in the RUN position so the 8.4-inch touchscreen is fully booted.
- Press and hold the driver's temperature UP, temperature DOWN and front DEFROST buttons together for around 7 seconds.
- When the dealer/diagnostic menu opens, choose the radio-information entries near the top of the list - they list serial numbers, hardware/software revisions and similar identifiers.
- Note the full serial exactly as printed, including any leading letters such as
T00AMorTM9. - Press Done, or cycle the ignition off/on, to leave the menu.
Uconnect 5.0 (RA2) and Uconnect 3.0 (RA1)
- An equivalent on-screen serial-number readout is not consistently documented for these smaller radios.
- If the dealer-mode shortcut does not surface a serial entry, fall back to the chassis-label method.
Check the Serial by Pulling Out the Unit
If the serial does not appear on display, 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 shutting off the engine - pull the key out.
- Then detach the radio surround.
- Next, release the mounting points and move the radio forward.
- Look for a barcode label showing the serial number.
To remove the radio from the 2017 Ram 5500:
- Power down the vehicle and remove the negative battery cable for safety.
- Pry off the dashboard trim panel using a trim removal tool. Ram heavy-duty trucks can have sturdier trim pieces than the 1500.
- Remove the 4 Phillips mounting screws securing the radio to the mounting frame.
- Slide the radio out and locate the serial label on the radio casing.
HD Truck Note: Commercial trims of the 2017 5500 may have a more basic center stack that makes radio access quicker than higher trims.
Removing the Unit to Reach the S/N Tag
If the on-screen method is unavailable, or the radio is locked at the CODE prompt and you cannot reach the dealer menu, pulling the head unit out and reading the chassis label is the dependable way to get the serial on a 2017 Ram 5500.
Safety first
- Turn the ignition fully off and remove the key.
- Disconnect the negative terminal of the 12V battery.
- Wait several minutes before working near the dash so airbag circuits can fully discharge.
- Stay clear of yellow airbag wiring while pulling trim.
Tools to have ready
- Plastic trim/panel pry tools to release the dash bezel without marks.
- A T20 Torx driver for the screws hidden behind the rubber beauty plates at the top of the bezel.
- A Phillips driver for the two screws inside the lower console cubby (if your truck has the centre floor console).
- A 7 mm socket or driver for the four radio retaining screws.
- A phone/camera to photograph the chassis label.
Removal overview
- Lift the rubber RAM-branded beauty plate at the top of the bezel with a fingernail or plastic pick to reveal two T20 Torx screws and back them out.
- Lift the rubber pad inside the cubby above the centre HVAC vents to expose a single T20 screw and remove it.
- If the truck has the centre floor console, lift the rubber pad at the front of the console well and remove the two Phillips screws underneath.
- Beginning at a lower edge, gently pry the bezel outward; it is held by retaining clips. Walk the tool around the perimeter to release each clip.
- Pull the bezel forward and unplug any small switch/HVAC connectors on its back.
- Undo the four 7 mm screws now visible at the corners of the radio chassis.
- Slide the head unit out and disconnect the main wiring harness and antenna lead.
Where the serial sits
- Look for a printed label on the metal housing - typically on the top or side face of the chassis.
- Copy the long alphanumeric string next to the barcode and watch out for similar characters (O vs 0, I vs 1).
Tips
- Photograph the label so the serial is preserved as a permanent reference.
- Reassembly is the reverse: harnesses on, four 7 mm screws home, bezel pressed in until each clip seats, T20 and Phillips screws restored, then reconnect the battery.

These are the Common Serial Formats
The 2017 Ram 5500 uses the same radio components as other Ram trucks. Serial number prefixes:
T00AM– Harman Uconnect (standard prefix)T00BE– Continental Uconnect variantTM9– Older Harman unitsT0MYD– Newer Harman units (2019+)
The 2017 5500 may have: RA2 (4.3" base), RA1 (5.0"), RA3 (8.4" Classic), or RA4 (8.4" 4C, newer). Serial is 14 characters.
Reminder The serial number starts with a code prefix (T00AM, T00BE, etc.) – don't mistake it with the radio part number (starts with P05064 or 68).
Common Serial Number Patterns You May See
The 2017 Ram 5500 could leave the factory with one of several Uconnect head units, each built by a different supplier, so the serial-number format varies by radio. The patterns below are the ones most often reported by owners and unlock services for this generation.
Continental-supplied Uconnect 8.4 (RA3 / RA4)
- Frequently shown with a
T00AMprefix followed by a numeric tail, for example a string resemblingT00AM1234567. - The prefix is printed inline with the rest of the serial on the chassis label.
Panasonic-supplied Uconnect units
- Often start with
TM9followed by additional digits or letters. - This pattern has been widely associated with Panasonic-built Mopar radios from the Uconnect 8.4 era.
Uconnect 5.0 (RA2) and Uconnect 3.0 (RA1) base radios
- Also carry a printed serial label on the chassis, but the prefix can vary by supplier batch.
- Copy the full string off the label rather than assume a fixed format.
If the alphanumeric you read does not match any of these patterns, double-check that you have the serial line and not the part number. The serial is normally the longest string on the label and is the one tied to the barcode.
Got the Code? Here's How to Enter It
After receiving 2017 Ram 5500 radio code from the serial, you're ready to reactivate the radio.
Many drivers get stuck at this stage because input methods can look different across radio versions, but it's usually quick.
When the radio shows ENTER CODE, it means the unit is waiting for the correct numbers.
Step-by-Step Code Input Guide
To input the unlock code on the 2017 Ram 5500:
- Turn ignition to ON. The radio display displays "ENTER CODE" or "CODE".
- Touchscreen models (8.4" Uconnect): Tap the on-screen keypad to enter each digit of the 4-digit code.
- Non-touchscreen (base Uconnect): Press preset buttons 1-4 to cycle to each digit, then press Enter/OK to confirm.
Lockout: 3 wrong attempts = 60-minute lockout. Ignition must stay ON. Commercial vehicles that frequently have battery disconnects may encounter this lock more often.
How to Enter the Code on the 2017 Ram 5500
Once you have the correct anti-theft code for your 2017 Ram 5500 radio, the entry itself is quick - but the radio will lock you out for half an hour if you keep guessing, so verify before you start.
Limited Attempt Warning
Three attempts is the limit. Three wrong codes in a row place the radio in a WAIT state and the display reads WAIT. To clear it, the radio must remain powered with the ignition in RUN for a continuous 30 minutes. Switching the key off does not bypass the timer (the truck may be driven during this time).
Entering the code
- Turn the ignition to RUN or ACC so the radio powers up and shows the CODE / Anti-Theft prompt.
- On the 8.4-inch Uconnect (RA3/RA4), tap each digit on the touchscreen number pad.
- On the 5-inch Uconnect 5.0 (RA2), enter the digits using the on-screen keypad.
- On the base Uconnect 3.0 (RA1), enter the four-digit code using the preset (1-6) buttons in sequence.
- Confirm with the OK/Enter on-screen control or the equivalent hardware button.
- When accepted, the radio returns to the normal home screen and audio resumes.
If it does not unlock
- Stop after the second wrong attempt and re-verify the serial used to obtain the code.
- Make sure no leading letters or trailing digits were dropped from the serial.
- If
WAITappears, leave the radio powered for the full 30 minutes before retrying.
Steps to Unlock Your 2017 Ram 5500 Radio
Vehicle radios use anti-theft codes tied to the radio unit itself rather than the vehicle model or production year.
- The system uses the 5500's radio serial to retrieve the unlock code.
- After entering the serial into the form above, the system identifies the radio unit and generates the code that you need.
- Use the code to unlock the radio immediately.
- This approach saves time compared to traditional methods for 2017 Ram 5500.
Fixing Common Code Entry Problems for 2017 5500
HD Ram radios may have the serial accessible via Dealer Mode (8.4" RA3: hold Climate Up + Climate Down + Front Defrost 5 sec; then System Info → Radio Part Info → Serial Number) or on the barcode sticker on the radio chassis.
Serial: 14 chars starting with T00AM, T00BE, TM9, or T0MYD. Never mistake this with the part number (P05... or 68...).
No code prompt means the anti-theft hasn't triggered yet. To trigger it: pull the radio fuse and reinsert it, then restore power and turn ignition ON. The "ENTER CODE" screen appears on startup.
HD Ram code entry varies by radio trim: 8.4" Uconnect (RA3/RA4) uses touchscreen-only entry — tap each digit on the on-screen keypad. Base Uconnect (RA1/RA2) uses preset buttons 1–4 to scroll to each digit, then Enter/OK to confirm.
The Uconnect enters lockout after 3 wrong entries. The screen keeps showing "ENTER CODE" or "CODE" but ignores all input.
To reset: Ignition ON, 60 full minutes without switching off the truck. Fleet-managed heavy-duty trucks that get turned off frequently must finish the full wait in one sitting. Cycling the ignition restarts the 60-minute timer.
HD Ram trucks have a mix of radios (RA1/RA2/RA3/RA4 depending on trim and year). Each unit's label contains both the serial (14 chars: T00AM, T00BE, TM9, or T0MYD prefix) and the part number (P05... or 68...). Only the serial generates the unlock code.
Base trim radios often have hard-to-read labels. Clean the label before reading, or photograph it and zoom in to verify each character.
