Find Ram ProMaster City 2020 Radio Code In Seconds

Why Did the Radio Lock and Ask for a Code?

The ProMaster City's Uconnect self-locks after any power interruption. Small commercial vans frequently go through battery service and fitout work, so this happens regularly.

Common causes: battery replacement (most frequent), fuse failure after accessory installation, buying pre-owned without the code, or battery fully drained from sitting unused.

The code is tied to the radio's serial number — not the vehicle VIN.

Radio Serial Number Explained - Finding It on Your Ram

The first step is finding the radio S/N.

Many people assume the code depends on the Ram model or year, but actually, the unlock process depends on the unique radio unit's serial number.

This number identifies the exact head unit installed in your Ram ProMaster City.

This is actually better, because if you have bought an aftermarket radio, the VIN or other vehicle-specific data wouldn't be of much use.

Depending on the radio used, you can see the serial directly from the screen or by looking at the label on the radio chassis.

2020 Ram ProMaster City - Which Radio Did You Get?

The 2020 ProMaster City carries forward the same single-tier Uconnect 3 lineup used since the mid-cycle refresh, with no Uconnect 4 or Uconnect 5 option offered for this Doblo-based body. There is one factory head unit, plus an optional Mopar/Garmin navigation card.

Uconnect 3.0 with 5-inch touchscreen (RA2-style) - standard on Tradesman and Tradesman SLT trims for 2020. Visual ID: small 5-inch colour touchscreen at the top of the centre stack with hard buttons running along the bottom edge of the screen, AM/FM/SiriusXM with Bluetooth streaming audio, Voice Command and a single USB port. Apple CarPlay and Android Auto are not supported on this generation Uconnect 3.
Uconnect 3.0 with 5-inch touchscreen plus Mopar Navigation - the same 5-inch hardware activated with the optional Mopar/Garmin navigation SD card. Visual ID: identical fascia to the standard 5-inch unit, but with a NAV/Map tile on the home screen and a Mopar SD card seated in the dash slot.

Field check: 5-inch screen with hard buttons below it, no Apple CarPlay or Android Auto on the home screen, and an upper dash clipboard tray sitting directly above the radio.

Quick Method: Find the Serial Number on the Screen

The method for 2020 Ram ProMaster City is this:

The 2020 Ram ProMaster City is a compact commercial van built on the Fiat Doblo platform. It is equipped with the Uconnect 5.0" (RA1) touchscreen in most trims. The ProMaster City's radio does not typically support the Dealer Mode screen diagnostic.

To retrieve the serial number, you must physically remove the radio and locate the serial from the barcode sticker on the back or side of the unit.

ProMaster City's Hardware Label Method

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.

Usual approach:

Start by completely powering down the engine - pull the key out.
Then detach the dashboard bezel.
Next, unscrew the mounting points and move the radio forward.
Look for a barcode label showing the serial number.

To remove the radio from the 2020 Ram ProMaster City:

Switch off the vehicle.
Look for release holes on each side of the radio faceplate. The ProMaster City may use European-style extraction holes.
If release holes are present: Insert DIN removal keys into the slots and ease the unit out.
If no release holes: Remove the center stack trim with a plastic pry tool, then remove the fasteners and pull the unit out.

ProMaster City Tip: The smaller dashboard of the ProMaster City gives you access to the radio without much difficulty. The radio unit is more compact than in full-size Ram trucks.

Find the S/N by Pulling Out the Unit

For the 2020 ProMaster City the most reliable way to read the radio serial is to pull the head unit and read the printed sticker on the chassis. The Doblo-based dash uses the same upper clipboard storage tray sitting directly above the radio that was used since launch, so the same removal sequence applies.

Safety first: turn the ignition off, take out the key, disconnect the negative battery terminal, and wait several minutes before touching wiring; never disturb any yellow airbag/SRS connectors and use plastic trim tools so nothing shorts or breaks.
Tools you will need: plastic trim removal kit, Phillips screwdriver, T-25 and T-10 Torx bits, flashlight, and a pair of DIN radio release keys (Mopar/Metra 86-3528 or equivalent); bent coat-hanger wire shaped to match the release-key profile can substitute in a pinch.
Removal overview: deal with the upper dash clipboard/storage tray above the radio first; lift the lid, back out the visible Torx screws and ease the tray forward to expose the upper mounting points around the radio.
Releasing the radio: insert the DIN release keys into the small holes either side of the head unit fascia until the internal clips release, then pull the radio straight out using the keys as handles.
Disconnect carefully: release the antenna lead and the multi-pin power/data connectors on the back of the unit before lifting it fully out.
Find the label: the serial number is printed on a barcode/sticker label on the top, side, or rear of the chassis, alongside the part number and supplier markings.
Tips: photograph the label up close in good light and double-check ambiguous characters such as 0/O, 1/I and B/8 before submitting the serial. If the DIN keys do not release the radio cleanly, reseat the keys rather than forcing the unit and risking the internal latches.

Common Serial Number Structures

The 2020 Ram ProMaster City radio features the same Stellantis serial format:

T00AM – Harman-manufactured Uconnect units
T00BE – Continental-manufactured units
TM9 – Older production Harman units

The ProMaster City most commonly features the RA1 (Uconnect 5.0") radio. The serial number is 14 characters and appears on a manufacturer label on the radio body.

Note Similar to the larger ProMaster, the ProMaster City is derived from a Fiat platform (Doblo). Nevertheless, the Uconnect serial format is the same with other Stellantis vehicles.

S/N Patterns and Prefixes

The 2020 ProMaster City still rides on the Italian/Turkish Fiat Doblo platform, so the head-unit supplier mix is closer to a European Fiat than to a US-built Mopar truck. The exact prefix on the chassis label depends on which supplier built the Uconnect 3 unit, and the printed sticker on the chassis is always the authoritative reference.

Uconnect 3.0 5-inch (with or without Mopar Navigation)

Often a 14-character alphanumeric string printed on the chassis label.
Mopar-style units may begin with T (for example T00AM, TM9 or TQ1); Continental-built variants are commonly seen with an A2C prefix on Doblo-platform radios.
The serial is usually a continuous run of letters and digits with no dashes or spaces.

Because the ProMaster City shares its dash and electronics with the Fiat Doblo, owner reports also describe shorter numeric serials and Magneti Marelli supplier codes. Copy the serial exactly as printed on the unit and avoid guessing characters that look unclear.

Entering the Radio Security Code

Once the system gives you 2020 Ram ProMaster City unlock code from the serial number, 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 dashed lines, it means the unit is waiting for the correct numbers.

Detailed Input Instructions for ProMaster City 2020

To enter the unlock code on the 2020 Ram ProMaster City:

Turn ignition ON. The Uconnect screen displays "ENTER CODE" or "CODE".
Press the touchscreen keypad to enter each digit of the 4-digit unlock code.
The radio restores after the final digit is entered.

Lockout: Entering three wrong codes results in a 60-minute lockout. The ignition must stay ON for the full lockout countdown.

Detailed Input Instructions for ProMaster City 2020

Once the unlock code has been retrieved for a 2020 ProMaster City Uconnect 3 head unit, it can be keyed in directly at the dash - no scan tool or dealer visit is required. Before paying for a code, it is worth checking the small storage compartment on the top right side of the dash (and the glovebox), as Mopar shipped many ProMaster City vans with the original anti-theft code printed on a card in a plastic bag stowed in that area.

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.
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 Uconnect 3 5-inch touchscreen, tap the on-screen number pad to enter each digit of the 4-digit code and confirm with the on-screen OK/Enter button.
If the on-screen keypad is unavailable on a particular software build, the numbered preset buttons (1-6) on the fascia can be used in sequence as the unit prompts.
If WAIT appears after wrong attempts, leave the radio powered with the ignition in RUN for a continuous 30 minutes before trying the correct code again; some owners report success after disconnecting the battery for around 30 minutes and reconnecting.

Understanding Unlock Issues with Your ProMaster City

The ProMaster City features a touchscreen (Uconnect 5.0" RA1). Tap each digit on the digital number pad. No physical preset buttons are involved. The radio unlocks automatically after the 4th digit is entered.

No code screen means the radio hasn't triggered yet. Trigger the lock: briefly disconnect the battery, then restore power and turn ignition ON. "ENTER CODE" appears on startup.

The ProMaster City radio label has both the serial number (14 chars: T00AM, T00BE, or TM9 prefix) and a part number (P05... or 68...). Always use the 14-character serial — not the part number.

After 3 wrong attempts, the radio locks out for 60 minutes. The display still shows "ENTER CODE" but blocks input during the wait.

To reset: Ignition ON, wait 60 full minutes without cutting power. Any power interruption restarts the 60-minute countdown.

As a compact van, its radio may use European-style extraction holes, making removal quicker than in pickup trucks. The serial label is on the side or back of the unit: 14 chars starting with T00AM, T00BE, or TM9.
