- The entire process takes only a few minutes and requires minimal effort.
Serial Number Location Guide for Ram 3500 2017
The important fact to know is that factory radios use a specific serial number to identify each unitindividually.
Your anti-theft system matches the code directly to this serial.
Different from car-specific data such as VIN or registration information, it is not determined by the model or production year, so you'll be able to get it even if you have an aftermarket radio.
Depending on the manufacturer and radio installed in your Ram 3500, the retrieval method varies.
Here are the most reliable ways to find it.
Which Head Unit Is in Your 2017 Ram 3500?
The 2017 Ram 3500 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.
Fast Serial Lookup Using Radio Controls
The method for 2017 Ram 3500 is this:
The 2017 Ram 3500 heavy-duty truck features the same Uconnect infotainment system as the Ram 1500. Depending on trim level, the vehicle could have a Uconnect 3.0/5.0" (standard trims) or Uconnect 8.4" (upper trims).
For 8.4" Uconnect (RA3): Press and hold the Climate Up, Climate Down, and Front Defrost buttons simultaneously for 5 seconds to access 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 find the serial label.
Get the Serial From the Touchscreen
For 2017 Ram 3500 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.
Pulling Out the Unit to Access the S/N on the Tag
If the serial number cannot be accessed through menu, use the hardware method.
Most Ram 3500 original radios include a sticker with the serial number printed on the chassis.
Steps:
- Turn off the vehicle.
- Remove the trim surrounding the radio.
- Unscrew the clips.
- Pull the unit forward to access the label.
The serial number is usually located near the printed code.
To remove the radio from the 2017 Ram 3500:
- Power down the vehicle and disconnect the negative battery cable as a precaution.
- Detach the center stack trim bezel using a plastic pry tool. Ram heavy-duty trucks may have thicker trim pieces than the 1500.
- Unscrew the four Torx T20 mounting screws securing the radio to the dash bracket.
- Slide the radio forward and locate the serial label on the radio casing.
HD Truck Note: Base W/T trims of the 2017 3500 may have a stripped-down center stack that makes radio access slightly easier than premium configurations.
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 3500.
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.

S/N Patterns and Prefixes
The 2017 Ram 3500 shares the same radio platform as other Ram trucks. Serial number prefixes:
T00AM– Harman Uconnect (most common prefix)T00BE– Continental Uconnect versionTM9– Earlier Harman productionT0MYD– Newer Harman units (2019+)
The 2017 3500 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 letter prefix (T00AM, T00BE, etc.) – do not mistake it with the FCA/Stellantis part number (starts with P05064 or 68).
Common Serial Number Patterns You May See
The 2017 Ram 3500 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
Once the system gives you 2017 Ram 3500 anti-theft code from the serial, you're ready to reactivate the radio.
Many drivers get stuck at this stage because input process 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.
Step-by-Step - Correct Entering Process
To input the unlock code on the 2017 Ram 3500:
- Turn ignition to ON. The radio display displays "ENTER CODE" or "CODE".
- Touchscreen models (8.4" Uconnect): Use the on-screen keypad to enter each digit of the 4-digit code.
- Non-touchscreen (base Uconnect): Press preset buttons 1-4 to select each digit, then press Enter/OK to confirm.
Lockout: 3 incorrect attempts = 60-minute lockout. Ignition must stay ON. Heavy-duty trucks that often have battery disconnects may see this lock more frequently.
How to Enter the Code on the 2017 Ram 3500
Once you have the correct anti-theft code for your 2017 Ram 3500 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.
Why Did the Radio Lock and Ask for a Code?
Uconnect self-locks after any power interruption. Heavy-duty work trucks see this more than most because batteries are replaced as part of regular fleet maintenance.
Common causes:
- Battery replacement — the most frequent trigger
- Failed fuse — especially after upfit installation
- Buying the truck fleet without the code
- Battery fully drained from sitting on a lot
The code is derived from the radio's serial number — not the truck's VIN.
Understanding Unlock Issues with Your 3500
HD Ram trucks have a mix of radios (RA1/RA2/RA3/RA4 depending on trim and year). Each unit's label includes both the serial (14 chars: T00AM, T00BE, TM9, or T0MYD prefix) and the part number (P05... or 68...). Just the serial generates the unlock code.
Base trim radios often have hard-to-read labels. Wipe it down before reading, or take a picture and zoom in to verify each character.
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 physical label on the radio chassis.
Serial: 14 chars starting with T00AM, T00BE, TM9, or T0MYD. Don't confuse this with the part number (P05... or 68...).
The Uconnect locks after 3 wrong entries. The display still shows "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 used in rotation must finish the full wait without power interruption. Cycling the ignition resets the 60-minute timer.
HD Ram code entry depends on radio trim: 8.4" Uconnect (RA3/RA4) uses touchscreen-only entry — tap each digit on the virtual number pad. Base Uconnect (RA1/RA2) uses preset buttons 1–4 to cycle each digit, then Enter/OK to confirm.
No code prompt means power hasn't been interrupted. To trigger it: briefly disconnect the battery, then restore power and turn ignition ON. The "ENTER CODE" prompt appears on startup.
