What does Acura radio code look like?

Acura radio codes are numeric security sequences that unlock the factory stereo after power is restored. In most models, the code appears as a short string of digits—typically 4 to 6 numbers—that must be entered correctly to regain radio operation.

What the code looks like

The unlock code is a purely numeric string. Its length can vary by model year and radio system, but common patterns are four, five, or six digits such as 1234, 48271, or 439102. There are no letters or symbols in the code, and you enter it using the radio keypad or preset buttons.

Typical formats across Acura models

Most Acura radios display a 4–6 digit code when the unit is locked. Some older or specialty systems may use longer sequences, but the standard is a concise numeric string without spaces or letters.

Where the code comes from

The Acura radio code is tied to the radio’s unique serial number, not a universal car password. The code is usually provided by the dealer or documented in the vehicle’s records. If you’ve lost the code, you’ll typically need the radio serial number (S/N) and proof of ownership to retrieve or reissue it.

Finding or confirming the radio serial number can involve checking the owner’s manual, a radio-code card that came with the car, or a label on the radio itself or inside the glove box. If you cannot locate the serial or the code, contact an authorized Acura dealer or Acura customer support for assistance.

Before attempting retrieval, be aware that access to the serial number and corresponding code requires proper ownership verification. In some cases, the dealer will generate a fresh code after confirming the vehicle and radio details.

Where to look or who to contact to obtain the code or serial

• Owner’s manual or any radio-code card supplied at purchase.


• Label on the radio unit or a sticker inside the glove box or trunk area, depending on the model.


• Acura or Honda dealership, or official customer support, with your VIN and proof of ownership.


• Authorized service centers or reputable code-recovery services that can generate the code from the radio’s serial number (verification required).

Having the radio serial number is the key to retrieving the correct code and resolving a locked unit.

Using the code to unlock the radio

Once you have the numeric code, input it on the radio’s keypad. The digits are entered one by one; a correct sequence restores normal operation. Be mindful that repeated incorrect attempts can trigger a lockout or require dealer intervention to reprogram the unit.

If the code is entered correctly, the radio should resume normal function and recall saved stations. If the system remains locked or you cannot input the code, contact your Acura dealer for assistance to avoid potential damage or permanent lockout.

Summary

Across Acura models, the radio unlock code is a numeric, 4–6 digit sequence tied to the radio’s serial number. It is not universal and must be obtained from the dealer or documented in the vehicle records. To recover it, locate the radio serial number or consult the owner’s materials, then verify ownership with an authorized dealer. With the correct code, the radio unlocks and returns to normal operation; without it, professional assistance is typically required.

Manufacturers sometimes put a sticker with the radio code on the inside of the glove box door or along the sides. Take a good look for a sticker with a 4- to 5-digit code—this is often the radio unlock code.

How do I find my Acura radio code?

You can retrieve an Acura radio code by checking your owner's manual for the Anti-Theft Radio Identification Card, looking for a sticker in the glove box, or using the online retrieval tool on the Acura website with your VIN and radio serial number. If you only have the serial number, you can call Acura Customer Service to get the code after verifying your identity.
 
1. Check your vehicle and documents

• Owner's Manual: Look for the "Anti-Theft Radio Identification Card." The code is usually the shorter, bold number in the lower-right corner. 
• Sticker: Check for a sticker with two numbers in your glove box, on the door jamb, or in the trunk jamb. The top number is typically your radio code. 
• Maintenance Journal: Your code may have been recorded by the technician in your maintenance journal. 

2. Use the online retrieval tool 

• Go to the Acura radio code retrieval website. 
• Enter your vehicle's VIN, the radio's serial number, and your contact information (email and phone number). 
• The code will be sent to you via email. 

3. Contact Acura Customer Service

• If you have the serial number but not the code, call Acura Customer Service. 
• You will need to verify your identity before they provide you with the code. 

How to find your serial number

• Manual/Sticker: The serial number is often on the same card or sticker as the radio code. 
• Display: For some models, you can find the serial number by holding down presets 1 and 6 while turning the radio on. The serial number will appear on the display.

You need to look in your glove compartment inside your service booklet. It is possible that the car radio code is written on one of the pages. Also in the user manual of the original car radio, you can find the code printed inside the booklet.

How do you figure out your radio code?

To find your radio code, first check the owner's manual or glove box for a sticker or card containing the code. If you can't find it there, you may need to retrieve the radio's serial number from the device itself and then use the manufacturer's website or a dealership to get the unlock code. 
Option 1: Check your vehicle and documentation 

• Owner's Manual: Look inside the vehicle's owner's manual. The code may be on a sticker or a separate card that came with the manual. If you bought the car used, the previous owner may have written it down there. 
• Glove Box: Many manufacturers put a sticker with the radio code and serial number inside the glove box. 

Option 2: Retrieve the serial number and use the manufacturer's website 

• Find the Serial Number: The method for finding the serial number varies by car model, but you can often retrieve it by a specific button combination while the radio is on. For some cars, like Honda, you can find the serial number on the display by following instructions on the manufacturer's website. 
• Use the Manufacturer's Website: Go to the official website for your car's brand (e.g., Honda MyGarage, Acura's website) and use the serial number and your vehicle's VIN to get the code. 
• Contact the Manufacturer: If you can't find the code online, contact the manufacturer's customer service hotline. You will likely need to provide proof of ownership and your VIN. 

Option 3: Visit a dealership

• Contact a Dealership: If other options fail, contact a local authorized dealership for your car's brand. 
• Provide Information: You will need to provide the radio serial number (if you know it) or the vehicle's VIN. You may also need to provide proof of ownership. 
• Remove the Radio: In some cases, a dealership may need to physically remove the radio to find a sticker on the back with the serial number.
