Why Is the Radio Asking for a Code?
The 5th-gen Ram 1500's Uconnect 4C activates anti-theft after any power interruption. Fifth-gen 1500 owners encounter this most often because of:
- Battery replacement — the most common trigger across all Uconnect variants.
- A failed fuse — frequent after aftermarket audio or accessory installation.
- Buying pre-owned without a known unlock code.
- Battery drained completely from long storage.
The code is tied to the radio's own serial number — not the VIN.
Locate the Serial Number Needed to Generate Ram 1500 2022 Radio Code
The important fact to know is that factory radios use a specific S/N to identify each unitindividually.
The anti-theft system links the code directly to this serial.
Unlike car-specific data like 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 maker and radio installed in your Ram 1500, the retrieval method is different.
Here are the best ways to locate it.
Radios Offered in the 2022 Ram 1500
For 2022 Stellantis dropped Uconnect 4 from the 8.4-inch and 12-inch screens on the DT Ram 1500: Uconnect 5 became the standard infotainment platform on those displays. The base 5-inch radio carried over for fleet / Tradesman buyers.
Uconnect 3 / 4 5-inch (sales code UAG) is the small base radio, standard on Tradesman. Visual ID: 5-inch display flanked by hard buttons and tuning knobs, no Apple CarPlay / Android Auto. The simplest 2022 head unit.
Uconnect 5 8.4-inch (sales codes UBM non-NAV and UBL NAV) is the 8.4-inch landscape Uconnect 5 unit, standard across Big Horn / Lone Star, Laramie and most non-Limited trims. Visual ID: 8.4-inch landscape glass running the redesigned Uconnect 5 multi-tile home screen, wireless Apple CarPlay and wireless Android Auto, multi-profile support, over-the-air updates.
Uconnect 5 12-inch (sales code UBQ) is the headline 12-inch portrait Uconnect 5 touchscreen, optional on Laramie and standard on Longhorn and Limited. Visual ID: very large vertically oriented 12-inch screen with split-screen multitasking, wireless CarPlay / Android Auto in the top tile, vehicle controls below.
Quick field test: small 5-inch with knobs = UAG; 8.4-inch landscape with the multi-tile Uconnect 5 home screen = UBM (no NAV) or UBL (with NAV); large vertical 12-inch portrait with the same Uconnect 5 graphics = UBQ.
Before Removing the Radio, Try This Screen Method
The method for 2022 Ram 1500 is this:
The 2022 Ram 1500 DT-body is equipped with the Uconnect 4C (RA4) with either the 8.4" standard or optional 12" portrait touchscreen in higher trims. 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 the glass) simultaneously for about 5 seconds.
- Dealer Mode appears on the display.
- Navigate to: System Info → Radio Part Info → Serial Number.
12" Screen Note: On the 2022 1500 with the 12" portrait display, press both bottom bezel corners. Try using two fingers at once. The Dealer Mode method is preferred before attempting removal of this larger module.
Before Removing the Radio, Try This Screen Method
The 2022 Ram 1500 with the 8.4-inch UBM / UBL or the 12-inch UBQ ships with Uconnect 5. Stellantis has restricted dealer-mode access on Uconnect 5 head units via over-the-air updates, and there is no consistently documented hidden-menu shortcut for displaying the radio serial on these units.
Result: for 2022 Ram 1500 Uconnect 5 trucks the on-screen serial method is not a reliable path. We do not list a specific button shortcut here because we cannot confirm one that works across current Uconnect 5 software builds.
If the truck is fitted with the legacy 5-inch UAG base radio, that unit also does not expose the serial through a documented dealer menu.
For all 2022 Ram 1500 trims, plan on reading the serial from the chassis label (head-unit removal, see the next section) or have a Mopar dealership pull it via a wiTECH diagnostic session. The chassis-label method remains the most dependable way to capture the correct serial on Uconnect 5 trucks.
Check it by Pulling Out the Unit
If the serial number cannot be accessed through menu, use the hardware method.
Most Ram 1500 original radios include a label with the serial number printed on the casing.
Step-by-Step Approach:
- Switch off the vehicle.
- Lift the bezel surrounding the radio.
- Loosen the fasteners.
- Move the unit forward to access the label.
The serial number is usually located near the printed code.
If Dealer Mode won't open on the 2022 Ram 1500, physical removal is the alternative:
- Turn off the vehicle.
- Remove the surrounding trim panel using a plastic pry tool. The 5th-gen 1500's modern interior uses snap-fit clips.
- Remove the mounting screws (Torx T20 or T25) securing the infotainment unit.
- Pull the unit forward to access the serial label on the side of the module.
12" Screen Note: The 12" portrait module is larger than the 8.4". Support it carefully when extracting. Try the on-screen method before removal.
Manufacturer Label Inspection
On a 2022 Ram 1500 the printed chassis label is the most dependable place to read the radio serial because Uconnect 5 has restricted on-screen dealer mode. The DT centre stack is closely integrated, and the 12-inch portrait UBQ in particular sits inside a deeply integrated bezel.
Safety first. Turn the ignition off, take out 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 so nothing shorts or breaks.
Tools you will need. Plastic trim removal kit, Phillips and small Torx (T20 / T15) bit set, 7 mm socket, flashlight.
Removal overview - 8.4-inch UBM / UBL. 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 for a third T20 screw. Remove all three, then carefully pry the centre stack bezel free with a plastic trim tool. With the bezel off, four 7 mm screws hold the radio cage to the dash support; remove them, slide the unit rearward and disconnect the antenna lead and the multi-pin power / data harness.
Removal overview - 12-inch portrait UBQ. The 12-inch portrait Uconnect 5 screen sits 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.
Where the serial sits. The serial number is printed on a barcode / sticker label on the top or side of the radio chassis, next to the part number and supplier markings.
Tips. Photograph the label up close and double-check ambiguous characters such as 0 / O, 1 / I and B / 8. Because the 12-inch portrait UBQ is so deeply integrated with the surrounding bezel and climate cluster, we strongly recommend a professional installer or dealership pull that unit if you are not experienced with DT-platform interior work.

Typical Serial Number Formats for 2022 1500 Radios
The 2022 Ram 1500 (5th-gen) Uconnect 4C (RA4) serial number formats:
T00AM– Harman Uconnect 4C (most common prefix)T00BE– Continental Uconnect 4C variantT0MYD– Updated Harman production (2020+)
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.
Serial Number Format Guide for 2022 Ram 1500
The factory radios on the 2022 Ram 1500 use the standard Mopar / Uconnect head-unit serial style. The exact prefix depends on which Uconnect tier shipped with the truck and on which supplier (Continental, Harman or Panasonic) built the unit.
Uconnect 5 8.4-inch (UBM / UBL) and 12-inch (UBQ)
The serial is typically a 14-character alphanumeric string printed on the chassis label. Because Uconnect 5 hardware is newer than the well-documented Uconnect 4 line, there is no published consensus prefix list specific to UBM / UBL / UBQ - so the label on the unit itself is the authoritative reference. Copy the serial exactly as printed and avoid guessing.
Uconnect 3 / 4 5-inch (UAG)
The 5-inch UAG base radio usually carries a Mopar / Harman or Panasonic-style serial printed on the chassis sticker. Copy the serial exactly as printed and avoid guessing characters that look unclear.
How Serial-Based Ram 1500 Radio Unlock Works
- Instead of contacting Ram dealer or searching forums you can find the code online using the radio S/N.
- Start by finding your radio's serial. The best place to search is on the unit itself, and sometimes it can be visible on the 1500's display.
- Enter it into the form above, and the system will retrieve the correct 2022 1500 unlock code.
- After getting it, input it using 1500's radio controls to release the blockade successfully.
- The entire process takes only a few minutes and requires no VIN, documents, or technical knowledge.
Code Entry Process for 2022 1500
After receiving 2022 Ram 1500 anti-theft code from the serial number, 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 simple.
When the radio shows dashed lines, it means the unit is waiting for the correct numbers.
Step-by-Step - The Correct Way to Enter It
Entering the unlock code on the 2022 Ram 1500's Uconnect 4C:
- The touchscreen displays "ENTER CODE" after a battery event.
- Use the touchscreen keypad to enter each digit of the 4-digit code.
- The radio restores after the 4th digit – no confirm button needed.
Lockout Warning: 3 wrong attempts = 60-minute lockout. Keep ignition ON. Turning off the ignition restarts the timer.
Detailed Input Instructions for Ram 1500 2022
Once the unlock code has been retrieved for a 2022 Ram 1500 head unit, it can typically be entered at the dash. Manual code entry is well documented on Uconnect 4 hardware; on Uconnect 5 trucks of this era, owner-forum reports continue to describe a manual code prompt rather than a fully VIN-only auto-pairing.
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.
Entering the code. 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 8.4-inch UBM / UBL and the 12-inch UBQ, 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, press the numbered preset buttons in sequence to enter the four-digit code.
If a wrong code was entered. If WAIT appears after incorrect attempts, leave the radio powered with the ignition in RUN for the documented cool-down period (about 30 minutes; the vehicle may be driven during this time) before trying the correct code again.
Understanding Unlock Issues with Your 1500
No code prompt means the Uconnect 4C hasn't locked yet. To force the code screen: briefly disconnect the battery, then turn ignition ON. The prompt shows on startup.
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 last digit. On the 12" portrait display: same process — same touchscreen input.
The 5th-gen Ram 1500's Uconnect 4C locks after 3 wrong entries. The screen continues to display "ENTER CODE" but ignores all taps during the lockout.
To clear: Keep ignition ON for a full 60 minutes. Any power interruption resets the timer. Work trucks or tow rigs that get turned off at job sites must complete the full wait without interruption.
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 rear of the module, accessible only after removal. Double-check the label and contact support if the code still fails.
The Uconnect 4C serial can be read via Dealer Mode on the 1500's touchscreen (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...).
