Common Acura MDX Radio Code Problems
Many owners encounter radio code issues on their MDX after electrical work.
Below are the most frequent situations when this can occur.
Lock After a Battery Work
After a battery change, your radio may show a CODE message.
This happens because the radio loses power, which triggers the anti-theft system.
Other Scenarios
- After a jump-start, the radio may lose power and request a radio code.
- When the radio is removed, it usually locks automatically.
- If a fuse blows, the radio can lock itself.
- After an ECU reset, software update, or electrical repair, some Acura MDX radios ask for a code.
The Radio Code - What is It and Why It's Important?
A radio unlock code, also known as an anti-theft code is a unique numeric unlock key that restores access to your car stereo after it has been disabled.
This anti-theft code is triggered when the radio is disconnected from power.
Automakers include this feature to protect factory stereos from theft.
If power is cut, the radio locks automatically and asks for the CODE before it can be used again.
Once the correct numbers is entered, the stereo is fully reactivated.

Below are the most reliable places to look.
Look for it in the Vehicle Itself
- In the owner's handbook, often on a separate code card.
- In the service booklet provided with the car.
- On the head unit casing if the unit was previously removed.
- On a sticker in the center console.
- Near the spare tire, where some manufacturers place radio labels.
Can the Dealer Get You the Code?
A Acura dealer can usually retrieve the security code using your MDX'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 anti-theft code for your radio.
Disadvantages:
- You usually need to book an appointment and bring vehicle paperwork.
- 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.
- Some older Acura MDX radios may require manual lookup.
How to Find the Serial Number on a MDX's Radio
To get the correct unlock code, you first need the serial number from the radio.
Depending on your MDX, you can see it on the screen or find it on the radio unit itself.
Common abbreviations are S/N, SN, Serial, Serial Num., Serial Number...
These are the easiest ways to locate it:
1. Viewing MDX's S/N on the Display
Unfortunately, on Acura MDX radios the serial number is not shown 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 S/N on the Radio Sticker
To find the serial number, you'll need to take out the head unit from the dashboard.
- Start by turning off the ignition and removing the trim panel.
- Next, release the clips and pull the unit forward to check the label on the back 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 equal. You can find both on the sticker, but you only care for the first one.
