How to find Ram 1500 2020 radio serial number

Steps to Unlock Your 2020 Ram 1500 Radio

Car radios use anti-theft codes tied to the radio unit itself instead of the vehicle model or production year.

  • Our lookup service works by matching your Ram 1500 radio's serial number.
  • Once the serial number is submitted, 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.

Entering the Radio Security Code

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

Ram OEM units display a CODE prompt when ready for input.

The process is simple, but button layouts and confirmation methods may differ slightly depending on the radio version installed in your 1500.

Entering Process Explained

Entering the unlock code on the 2020 Ram 1500's Uconnect 4C:

  1. The touchscreen displays "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. Turning off the ignition restarts the timer.

Correct Entering Process

Once the unlock code has been retrieved for a 2020 Ram 1500 Uconnect 4 head unit, it can be entered straight at the dash - no scan tool or dealer visit required.

  1. Limited attempts: Mopar / Uconnect head units only accept three incorrect tries before the radio enters a WAIT state, so confirm every digit before pressing it.
  2. Turn the ignition to RUN / ACC so the radio powers up while the engine stays off.
  3. Wait for the display to show CODE, Please enter Anti-Theft Code or a similar prompt.
  4. On the 8.4-inch UCQ / UAQ and the 12-inch UAX, key the digits using the on-screen number pad and confirm with the OK / Enter touch button.
  5. On the 5-inch UAG base radio, press the numbered preset buttons in sequence to enter the four-digit code.
  6. If WAIT appears after wrong attempts, leave the ignition in RUN with the radio powered for the documented cool-down period (about 30 minutes; the vehicle may be driven during this time) before trying the correct code again.

How to Find the Serial Number on Your 2020 Ram 1500 Radio?

The important thing to know is that factory radios use a specific serial number to identify each unitindividually.

The anti-theft system links the code directly to the serial.

Different from car-specific data such as VIN or registration info, it is not determined by the model or production year, so you'll be able to retrieve it even if you have a radio that you installed afterwards.

Depending on the manufacturer and radio installed in your Ram 1500, the access method varies.

Here are the most reliable ways to locate it.

2020 Ram 1500 - Which Radio Did You Get?

The 2020 Ram 1500 carries the same Uconnect 4 line-up as the 2019 launch year. Four head units are split across the trim ladder, separated mainly by screen size and built-in navigation.

  1. Uconnect 3 / 4 5-inch (UAG) - 5-inch non-touchscreen base radio standard on Tradesman. Visual ID: small 5-inch display with surrounding hard buttons and tuning knobs, no Apple CarPlay or Android Auto. The simplest radio in the line-up.
  2. Uconnect 4C 8.4-inch non-NAV (UCQ) - 8.4-inch landscape touchscreen without built-in GPS. Standard on Big Horn / Lone Star, optional on Tradesman. Visual ID: 8.4-inch screen filling the dash bezel, Apple CarPlay and Android Auto present, but no Map / NAV tile on the home screen.
  3. Uconnect 4C NAV 8.4-inch (UAQ) - 8.4-inch landscape with built-in GPS. Standard on Laramie and higher, optional on Big Horn. Visual ID: identical 8.4-inch glass to UCQ, but the home screen carries a dedicated NAV / Map tile and full turn-by-turn navigation.
  4. Uconnect 4C NAV 12-inch (UAX) - the headline 12-inch portrait touchscreen, optional on Laramie, standard on Longhorn and Limited. Visual ID: very large vertically oriented 12-inch screen, split-screen multitasking, CarPlay / Android Auto run in the top half with vehicle controls below.

Quick field test: small 5-inch with knobs = UAG, 8.4-inch landscape with no Map tile = UCQ, 8.4-inch landscape with a Map tile = UAQ, very large vertical 12-inch screen = UAX.

Screen-Based Serial Lookup Method

The method for 2020 Ram 1500 is this:

The 2020 Ram 1500 5th-generation is equipped with the Uconnect 4C (RA4) with either the 8.4" standard-option or optional 12" portrait touchscreen on Rebel, Laramie, and above. 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 the glass) at the same time for approximately 5 seconds.
  3. Dealer Mode opens on the display.
  4. Navigate to: System Info → Radio Part Info → Serial Number.

12" Screen Note: On the 2020 1500 with the 12" portrait display, press both bottom bezel corners. Some owners find it easier to using both thumbs simultaneously. The Dealer Mode method is preferred before attempting removal of this larger module.

Display-Based Serial Number Retrieval

The 2020 Ram 1500 continues with Uconnect 4 across all trims, so the radio serial number can usually be read on screen via the hidden dealer / diagnostic menu, although some 2020 builds had dealer mode tightened by a Stellantis software update.

Uconnect 4C 8.4-inch (UCQ / UAQ)

  1. Switch the ignition to RUN / ACC and wait for the Uconnect interface to finish booting.
  2. Press and hold the driver-side temperature UP, the driver-side temperature DOWN and the front DEFROST buttons together for roughly 5-10 seconds.
  3. If the climate-button shortcut does nothing on a software-updated unit, press and hold the bottom-left and bottom-right corners of the screen at the same time for about 5-10 seconds.
  4. Browse to Radio Part Information / System Info to view the serial number on screen.
  5. Photograph the screen before transcribing the characters.

Uconnect 4C NAV 12-inch portrait (UAX)

  1. Place the ignition in RUN / ACC and let the 12-inch display finish loading.
  2. Press and hold the first (far-left) and last (far-right) hard buttons along the bottom edge of the 12-inch screen together for about 5-10 seconds until the dealer mode menu opens.
  3. Open the radio / system info section and read the serial number on screen.
  4. Snap a photo of the display so the characters can be copied accurately.

The 5-inch UAG base radio does not expose the serial through a documented dealer menu, so on that unit the chassis label remains the next step.

Releasing the Unit to View 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.

Usual approach:

  1. Start by completely turning off the engine - pull the key out.
  2. Then lift the trim panel.
  3. Next, loosen the mounting points and slide the radio forward.
  4. Look for a factory sticker showing the serial number.

If Dealer Mode won't open on the 2020 Ram 1500, physical removal is the alternative:

  1. Turn off the vehicle.
  2. Pry off the center stack trim using a plastic pry tool. The 5th-gen 1500's redesigned dash uses snap-fit clips.
  3. Unscrew the mounting screws (Torx T20 or T25) securing the infotainment unit.
  4. Pull the unit out to access the serial label on the rear of the module.

12" Screen Note: The 12" portrait module is heavier than the 8.4". Hold it with both hands when extracting. Try the on-screen method before removal.

View Serial by Pulling Out the Radio Unit

If dealer mode has been disabled on a 2020 Ram 1500 by a Uconnect software update, the printed chassis label remains the next reliable source for the serial. The DT Ram 1500 dash is closely integrated, and the 12-inch portrait UAX in particular is part of a deeply integrated centre stack.

  1. Safety first: turn the ignition off, remove the key, disconnect the negative battery terminal and wait a few minutes before touching wiring; never disturb the yellow airbag / SRS connectors and use plastic trim tools to avoid shorts and broken clips.
  2. Tools you will need: plastic trim removal kit, Phillips and small Torx (T20 / T15) bit set, 7 mm socket, flashlight.
  3. Removal overview - 8.4-inch UCQ / UAQ: lift the rubber mat in the cubby at the top of the centre dash to reveal two T20 Torx screws, and lift the rubber mat in the small cubby above the 12 V / AC outlet to reveal a third T20 screw. Remove all three, then carefully pry the centre stack bezel free with a plastic trim tool.
  4. Removal overview - 12-inch portrait UAX: the 12-inch portrait screen lives in a much larger integrated bezel that extends across most of the centre stack and is tied into the climate cluster - removal involves more trim panels and connectors than the 8.4-inch unit.
  5. Once the bezel is free, remove the four 7 mm screws holding the radio cage to the dash support, then slide the head unit rearward.
  6. Disconnect the antenna lead, the USB / aux harness and the multi-pin power / data connectors before fully extracting the unit.
  7. The serial number sits on a printed barcode / sticker label on the top or side of the radio chassis, next to the part number and supplier markings.
  8. Photograph the label and double-check ambiguous characters such as 0 / O, 1 / I and B / 8 before submitting the serial. Because the 12-inch portrait UAX is so deeply integrated with the surrounding bezel and climate cluster, we strongly recommend having a professional installer or dealership remove that unit if you are not experienced with DT-platform interior work.

Typical Serial Number Formats for 2020 1500 Radios

The 2020 Ram 1500 (5th-gen) Uconnect 4C (RA4) serial number formats:

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

Radio designations: RA4 (8.4" Uconnect 4C), UAQ/UAR (12" screen option). Serial: 14 characters alphanumeric.

Important Do not mix up the serial with the part number (P05064... or 68...) on the same label. Only the 14-char serial generates the code.

Common S/N Formats Used on 2020 Ram 1500 Units

The factory radios fitted to the 2020 Ram 1500 use the standard Mopar / Uconnect serial style. The exact prefix depends on the Uconnect tier shipped with the truck and on which supplier (Continental, Harman or Panasonic) built the unit.

Uconnect 4C 8.4-inch (UCQ / UAQ)

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

Uconnect 4C NAV 12-inch (UAX)

  1. Typically also follows the 14-character Mopar / Uconnect alphanumeric pattern printed on the chassis sticker.
  2. The label on the unit itself is the authoritative reference because the supplier mix can vary on this larger NAV unit.

Uconnect 3 / 4 5-inch (UAG)

  1. Usually carries a Mopar / Harman or Panasonic-style serial printed on the chassis sticker.
  2. Always copy the serial exactly as printed and avoid guessing characters that look unclear.

Troubleshooting Common Radio Problems - 1500 2020

The Uconnect 4C label on the Ram 1500 shows both the serial number (14 chars: T00AM, T00BE, or T0MYD) and the part number (P05... or 68...). Only the serial generates the unlock code.

For the large screen: the serial label is on the back of the module, visible only when removed. Re-read the label and reach out if the code still fails.

The 5th-gen Ram 1500's Uconnect 4C enters lockout after 3 wrong entries. The screen still shows "ENTER CODE" but blocks all taps during the lockout.

To clear: Keep ignition ON for a full 60 minutes. Turning off resets the timer. Ram 1500s used for towing that get turned off at job sites must complete the full wait in one sitting.

The Uconnect 4C serial is accessible via Dealer Mode on the 1500's touchscreen (System Info → Radio Part Info → Serial Number), or on the physical label on the unit housing after removal.

Serial: 14 chars starting with T00AM, T00BE, or T0MYD. Ignore the part number (P05... or 68...).

The Ram 1500 Uconnect 4C uses touchscreen-only code entry — tap each digit on the virtual keypad. No physical preset buttons are involved. The radio unlocks after the 4th digit. With the large screen: same process — tap each digit as normal.

No code prompt means the Uconnect 4C hasn't triggered. To force the code screen: pull the radio fuse and reinsert it, then turn ignition ON. The prompt appears on startup.

Why Did the Radio Lock and Ask for a Code?

The 5th-gen Ram 1500's Uconnect 4C locks automatically after the battery is disconnected or replaced. Fifth-gen 1500 owners see this primarily due to:

  • Battery replacement — the most common trigger across all Uconnect variants.
  • A failed fuse — frequent after aftermarket audio or accessory installation.
  • Buying used without the code.
  • Battery drained completely from sitting unused.

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