Radio Code Explained
When the radio is disconnected from power, it immediately locks and requires an anti-theft code to be entered before it can be operated.
A factory radio code (also known as an anti-theft code) is a security feature integrated into original car stereos to protect theft.
This system makes sure that a stolen radio becomes useless without the original code.
Entering the valid code restores full audio and infotainment functionality.
Acura TLX's Most Common Radio Code Triggers
Many drivers encounter security code prompts on their TLX after electrical work.
Below are the most common situations when this can occur.
Battery Change Problem
When the battery is disconnected, the Acura TLX radio enters anti-theft mode.
This security feature is designed to prevent theft by disabling the radio after electrical reset.
Other Scenarios
- Installing a used head unit will require the original anti-theft code.
- After an ECU or software reset, the radio may enter security mode.
- A fuse removal can cause the Acura TLX radio to lock.
- Jump-starting the vehicle can reset the radio, requiring the PIN.
Is Getting a Free Acura TLX Radio Code Possible
Before you pay for it, you should check a few places where the code is often stored.
Some drivers find their Acura TLX radio code without needing any tools or paperwork.
Here are the most common things to check first.
Look for it in the Vehicle Itself
- In the radio manual, often on a sticker page.
- Inside the glovebox, sometimes on a small card.
- In the boot compartment, on a radio label.
- In your maintenance booklet from the previous owner.
- On the radio unit itself, if it was removed before.
Can the Dealer Get It for You?
Dealerships can retrieve your radio code by checking the vehicle records in their system.
They typically ask for registration and ID before sharing the unlock code.
This is the official way to restore access to the factory radio.
Downsides:
- Some imported or older radios may need extra verification.
- You may need to contact service support during business hours.
- The lookup is often not instant and may require waiting.
- Dealers frequently charge a service fee (sometimes more than 100$).
Where to Search for the Serial Num. on your TLX
The only thing you'll need to find the corresponding code is your radio's serial number (not part number!).
On all Acura's, you can find it in one of these places:
- Displayed on the radio screen (by using some combinations of buttons)
- On the radio unit itself - you'll need to extract it and write down serial (which is not so hard).
Search for something that looks like: Serial Num., SN, S/N, Serial, Serial Number...
1. View the Serial Number on Acura TLX's Screen

Unfortunately, the unit must then be physically removed to find the serial on a manufacturer label on the radio casing.
2. How to Find the Serial Number on the Radio Unit's Sticker
The serial number is usually printed on a label attached to the radio casing.
Step 1: Turn off the ignition.
Step 2: After that, remove the dashboard trim.
Step 3: Then unscrew the radio brackets.
Step 4: Carefully pull the radio forward partially (Be careful not to damage the cables).
Step 5: Look for the serial number on the rear of the unit.
Step 6: Write down the full S/N carefully and come back to our website so that we can generate the code.

Now You Have the Code. How to Enter It?
You need to type in the anti-theft code into the system to unlock your Acura's radio.
When the unit is locked, the screen usually displays a code prompt.
You should use radio presets, control knob, or touchscreen to enter the numbers, then submit the code to reactivate the audio system.
Try not to make mistakes, because too many wrong attempts can temporarily lock the radio.
It will allow you a few incorrect tries before showing a SAFE message.
You can reset the lockout by leaving the radio on for 60 minutes or a set waiting period.
