Radio Code - Quick Explanation
A radio unlock code, sometimes also known as an anti-theft code is a security PIN that reactivates your car audio system after it has been locked.
This security code is triggered when the radio detects a power interruption.
Automakers include this feature to protect factory stereos from theft.
If power is lost, the radio stops functioning and asks for the CODE before it can be used again.
Once the valid numbers combination is entered, the stereo is unlocked.
Common Acura RL Radio Code Problems
Many owners encounter radio code issues on their RL after battery-related issues.
Below are the most typical situations when this can occur.
Battery Change Lock
When the battery is removed, the Acura RL radio locks automatically.
This security feature is designed to prevent theft by disabling the radio after power loss.
Other Scenarios
- Installing a used head unit will trigger the original radio code.
- After an ECU or software reset, the radio may lock.
- A fuse removal can cause the Acura RL radio to request a security code.
- Jump-starting the vehicle can reset the radio, requiring the PIN.
Quick Fixes 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 owners find their Acura RL 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 radio label.
- In your maintenance booklet from the previous owner.
- On the head unit itself, if it was serviced earlier.
Can the Dealer Get You the Code?
A Acura dealer can usually look up the radio code using your RL'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 vehicle paperwork.
- 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 Acura RL radios may require manual lookup.
Where to Search for the Serial Num. on your RL
The only thing you'll need to get the code is your radio's serial num. (not part number!).
On all Acura's, you can find it in one of these places:
- Directly on the radio screen (by using some combinations of buttons)
- On the radio unit itself - you'll need to extract it and write down your serial (which is not as hard as it seems).
Search for something that looks like: Serial, SN, S/N, Serial Num...
1. Viewing RL's S/N on the Display
Unfortunately, on Acura RL 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 sticker on the side of the radio.
2. Find the S/N on the Radio Unit's Sticker
To find the serial number, you'll need to remove the radio unit out.
- Start by turning off the ignition and taking off the dashboard bezel.
- Next, release the clips and slide the radio out to check the label on the side of the radio. Be careful not to damage the cables.
- Write down full serial number carefully and then come back to the website.
- Know that serial number and part number are not the same. You can find both on the sticker, but you only care for the first one.

Common Serial Number Prefixes on Acura RL Radios
Your Acura RL radio serial number may start with:
T0MYDTM9
You've Got the Code. How to Enter It?
Once you have the Acura's radio code, you can type it in using the radio buttons.
Most radios display "ENTER CODE", "----" or "XXXX" message when they are locked.
You typically use the number keys to select each digit.
After entering the full code, the radio will unlock automatically.
Be careful, because too many wrong attempts can temporarily lock the radio.
It allows a few missed shots before showing a LOCKED message.
You can reset the lockout by keeping the ignition on for one hour or a set waiting period.
