Finding the S/N on a 5500's Radio
The only thing you'll need to get the code is your radio's serial number (not part number!).
On all Ram's, you can find it in one of these places:
- Displayed on the radio screen (sometimes)
- On the radio unit itself - you'll need to pull it out and write down serial (which is not as hard as it seems).
Search for something like: Serial Num., SN, S/N, Serial, Serial Number...
1. Viewing 5500's S/N on the Display
Unfortunately, on Ram 5500 radios the serial number cannot be viewed on the screen.
In that case, you'll need to take out the head unit and check the label on the back of the radio.
2. Find the Serial Number on the Radio Sticker
To find the serial number, you'll need to take out the head unit out.
- Start by turning off the vehicle and taking off the dashboard bezel.
- Next, release the clips 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 carefully and come back to the website.
- Know that serial number and part number are not the same. You will find both on the unit, but you only care for the first one.

Many drivers encounter security code prompts on their 5500 after power loss.
Below are the most typical situations when this can happen.

Other Situations That Trigger a Radio Code on Ram 5500
- After a boost start, the radio may lose power and request a radio code.
- When the radio is removed, it usually locks automatically.

Places to Check Before Buying a Radio Code
Before you pay for it, it's worth checking a few places where the code is often already written down.
Some drivers find their Ram 5500 radio code without needing any tools or paperwork.
Here are the most common things to check first.
Check the Car and Its Documentation
- In the user guide, often on a separate code card.
- In the maintenance records provided with the car.

Can the Dealer Get You the Code?
A Ram dealer can usually retrieve the security code using your 5500's vehicle identification number.
In most cases, you need to contact the service department or visit the dealership and show vehicle documents.
Once verified, they can generate the original unlock code for your radio.
Disadvantages:
- You usually need to visit in person and bring ID.
- Dealers often ask for payment for the lookup service and it's sometimes more than 100$.
- The process can take hours depending on the model and database.
