How to Enter Radio Code Acura TL 2005

Having the radio code for your Acura TL 2005 is essential, especially if you experience a power interruption or replace the battery. Without the proper code, you won’t be able to use your radio or access other functions of the audio system. In this article, we will guide you through the process of entering the radio code for your Acura TL 2005 model.

Determining the Radio Code

If you don’t have the radio code for your Acura TL 2005, you can retrieve it using these steps:

  1. Check the User Manual: The radio code might be written down in the owner’s manual that came with your vehicle. Look for a card or a sticker with the code in the manual.
  2. Check the Glove Box: Some car owners keep the radio code card or sticker inside the glove box. Look for any labels or cards with alphanumeric codes.
  3. Contact the Dealership: If you can’t find the radio code anywhere, you can contact your local Acura dealership. Provide them with your vehicle identification number (VIN) and they should be able to retrieve the code for you.

Entering the Radio Code

Once you have the radio code, follow these steps to enter it into your Acura TL 2005:

  1. Turn on the Ignition: Start by turning on the ignition key to power up the audio system.
  2. Disable the Theft-Lock Function: If your audio system displays the word ‘CODE’ or ‘ENTER CODE’ on the screen, this means that the theft-lock function is enabled. To disable it, press and hold the radio power button until you hear a beep. The word ‘CODE’ or ‘ENTER CODE’ should disappear, allowing you to enter the radio code.
  3. Use the Preset Buttons: Your Acura TL 2005 radio system has six preset buttons labeled 1 to 6. These buttons will be used to enter the digits of the radio code.
  4. Enter the Code Digit by Digit: Use the preset buttons to enter the digits of the radio code one at a time. For example, if your code is ‘1234’, press the preset button 1 four times, preset button 2 three times, preset button 3 twice, and preset button 4 once.
  5. Confirm the Code: After entering the complete code, make sure it is correct. If it is, press the ‘FM’ button to confirm. The radio should now be unlocked and ready for use.

It’s important to note that the radio code is unique to each vehicle, and you should keep it in a safe place for future references. If you don’t have the code, make sure to retrieve it and perform the above steps to unlock your radio system.


In case you encounter any issues or the radio code doesn’t work, here are a few troubleshooting tips you can try:

  • Double-check the Code: Ensure that you have entered the correct radio code. Even a single wrong digit can prevent the radio from unlocking.
  • Check the Battery: If you recently replaced the battery or experienced a power interruption, ensure that the battery is properly connected and charged.
  • Disconnect the Battery: Disconnect the car battery for a few minutes and then reconnect it. This can sometimes reset the radio system and prompt the ‘CODE’ display.
  • Contact the Dealership: If all else fails, it’s best to contact your local Acura dealership. They will have the resources to assist you in unlocking your radio system.

Remember, each Acura TL 2005 comes with a unique radio code, and it’s essential to have it to fully enjoy your audio system. Keep the code in a safe place and perform the necessary steps whenever required to unlock your radio.
