What Exactly is a Radio Code?
A factory radio code, also known as an anti-theft code is a security PIN that restores access to your car stereo after it has been locked.
This factory security PIN is triggered when the radio is disconnected from power.
This system helps prevent stolen radios from working in other vehicles.
If power is interrupted, the radio locks automatically and requires the unlock CODE before it can be used again.
Once the valid numbers combination is entered, the stereo is fully reactivated.
Ram ProMaster City's Most Common Radio Code Causes
Your radio may lock automatically when it detects a power interruption.
These are the some well-known scenarios that trigger the radio code prompt.
Battery Change (Most Common)
After a battery replacement, your radio may lock.
This happens because the radio loses power, which activates the security lock.
Other Possibilities
- Installing a replacement head unit will require the original anti-theft code.
- After an ECU or software reset, the radio may enter security mode.
- A blown fuse can cause the Ram ProMaster City radio to lock.
- Jump-starting the vehicle can reset the radio, requiring the unlock code.
Is Getting a Free Ram ProMaster City Radio Code Possible
Before you pay for it, you should check a few places where the code is often already written down.
Some owners find their Ram ProMaster City radio code without needing any tools or paperwork.
Here are the easiest things to check first.
Look for it in the Car Itself
- In the owner's manual, often on a code card.
- Inside the center console, sometimes on a small card.
- In the trunk, on a service sticker.
- In your car paperwork from the previous owner.
- On the head unit itself, if it was removed before.
Getting a Ram ProMaster City Radio Code from the Dealer
A Ram dealer can usually retrieve the security code using your ProMaster City's VIN.
In most cases, you need to contact the service department or visit the dealership and prove ownership.
Once verified, they can generate the original anti-theft code for your radio.
Disadvantages:
- You usually need to visit in person and bring ID.
- Dealers often charge a fee for the lookup service and it can cost more than 100$.
- The process can take days depending on the model and database.
- Some older Ram ProMaster City radios may require manual lookup.
Finding the Serial N. on a ProMaster City's Radio
The only thing you'll need to find the corresponding code is your radio's serial number (not part number!).
On all Ram's, you can find it in one of these places:
- Directly on the radio screen (by using some combinations of buttons)
- On the radio body itself - you'll need to extract it and write down serial (which is not so hard).
Search for something that looks like: Serial, SN, S/N, Serial Num...
1. Viewing ProMaster City's S/N on the Display
Unfortunately, on Ram ProMaster City radios the serial number is not shown on the screen.
In that case, you'll need to remove the radio unit and check the label on the side of the radio.
2. Locating the Serial Number on the Radio Unit
To find the serial number, you'll need to take out the radio unit from the dashboard.
- Start by turning off the ignition and taking off the dashboard bezel.
- Next, unscrew the mounting bolts and pull the unit forward to check the label on the side of the radio. Be careful not to damage the cables.
- Write down full serial number precisely and come back to the website.
- Know that serial number and part number are not equal. You will find both on the unit, and you only care for the first one.

You've Got the Code. How to Enter It?
You need to enter the code into the system to unlock your Ram's radio.
In the locked unit, the screen usually shows a security message.
Based on the radio, use radio presets, control knob, or touchscreen to set each digit, then confirm the code to restore radio functionality.
If you fail multiple times, you may cause the ProMaster City's head unit to block further attempts.
When this happens, the screen can display messages like "CODE ERR", "ERROR", or a blank screen.
To unlock the system, you usually need to keep the ignition on for a waiting period or up to a full hour before trying again.
