You can find your 2003 Acura MDX radio code sticker in the glove box or affixed to the car’s manual. Look for a white sticker with a code labeled “Anti-Theft Radio Code.” Acura owners can also use their MDX’s VIN and radio serial number to retrieve the code.

If your battery has recently died or you’ve had it replaced, chances are you won’t be able to access your car’s radio again without inputting a security code.

If you’re confused about how to find a 2003 Acura MDX’s radio code, you’ve come to the right place!

Why your 2003 Acura MDX needs a radio code

Acuras are high-end, luxury cars, and their radios are popular targets of car thieves.

Your MDX’s anti-theft radio system makes the radio inoperable whenever it’s been disconnected from your SUV’s battery. So each time you disconnect an old battery to install a new one, your radio interprets this event as theft and shuts down accordingly.

To get your MDX radio back up and running, you’ll need to input a unique code assigned to your radio. But what if you don’t know where to find the radio code?

How to find your 2003 Acura MDX radio code

Finding a 2003 Acura MDX’s radio code is pretty straightforward. Begin by following these steps:

First steps for finding an MDX’s radio code
Step 1: Open your glove box. Inspect the inside and outside of the glove box, looking for a white sticker with the words “anti-theft radio code.” If you locate those words, they should be followed by a 5-6 digit code.
Step 2: If you can’t find the sticker in the glove box, locate the original owner’s manual. You may find a card in the owner’s manual with the code, or you may find a sticker on the manual with the code.

How to look up a 2003 Acura MDX radio code

If your MDX is more than 4-5 years old, the sticker may have fallen off, or your owner’s manual could be lost. It happens.

Luckily, you can still find your 2003 Acura MDX’s radio code. You’ll just need two pieces of basic information.

Find your Acura's Vehicle Identification Number (VIN)

and your radio’s serial number.

A VIN is the alpha-numeric code of 17 numbers and letters you’ve likely seen on your title, insurance documents, or your MDX’s registration.

Other places to look for the VIN are the plate fastened to the top of your MDX’s dashboard and the bottom side of the driver’s windshield.

Let’s say you find the VIN pretty easily. But what about your radio’s serial number? Thankfully, Acura engineers designed a way to get the radio’s serial number without taking out the radio!

How to find your radio’s serial number
Step 1: After putting the key in the ignition, turn the key to the ON/Accessory position, being careful not to turn over your MDX’s engine.
Step 2: Hold down the 1 and 6 preset buttons on the radio simultaneously for 6-7 seconds.
Step 3: With the help of a friend or by using your other hand, press down on the ON button for the radio while still holding down the 1 and 6 preset buttons.

Then, the radio’s 10-digit serial number should appear on the display.

Once you have found your MDX’s VIN and the radio’s serial number, the next step is to retrieve your 2003 Acura MDX’s radio code. Here are some options for getting the code:

Visit Acura’s

online lookup tool

and type in the requested information, which will include your VIN and the serial number of the radio

Call 1-800-999-1009 and provide the VIN and serial number (along with other information to prove you’re the MDX’s owner)

Call up your nearest Acura dealership and ask if they will provide the code over the phone. If not, go in with your VIN, serial number, and proof of ownership

Once you’ve found your 2003 Acura MDX’s radio code, the rest is simple. Input the 5-6 digit code using the radio preset buttons. After you enter the code, your radio should start working right away!
