You just had your battery replaced or a recent service completed. You turn on the radio and discover the radio has stopped working. Now what? In most cases, your radio has stopped working because a factory-enabled security system has been triggered — one designed for anti-theft purposes. Luckily, this common issue is rather simple to resolve when you have access to the radio code assigned to your particular year, make, model, and sometimes specific VIN number.

You might be wondering how to find the radio code to unlock your car stereo. If you’re in this situation, here are a few easy ways to gain access to the radio security code. Soon, you can reactivate your stereo and get back to enjoying those tunes as you drive down the road. Follow the listed 4 steps to find the radio code to your car’s stereo.

1. Check Your Owner’s Manual

The best place to locate a radio code is in the owner’s manual of your car. In most cases, the owner’s manual will be located in your glove box and will include general automotive service and maintenance tips, along with instructions on how to operate each system on the vehicle. Inside the owner’s manual, you’ll find an index located in the back, listed in alphabetical order. Simply look for radio, stereo, or security sections to see if this information is documented inside the manual. Sometimes, the car radio code will be written on a plastic or cardboard card inside the owner’s manual or the cover that holds the manual. If you purchased the car from a private owner or it’s a used car that has an owner’s manual, you might want to also inspect the inside covers or “notes” section. Sometimes previous owners will write down the radio security code.

2. Visit the Manufacturer’s Website

If you’re unable to locate the radio security code inside the glove box or the owner manual, the next step should be visiting the vehicle manufacturer’s website. Many automotive manufacturers have an online database that allows you to enter your year, make, model, VIN number, and even serial number to retrieve the security code or have it emailed to you. If you have an upgraded or aftermarket radio, you’d want to follow this step — except contact the radio’s manufacturer instead.

3. Visit your Local Dealership

If you’re unable to locate the radio security code on the manufacturer’s website, the next place to search is the dealership where the car was sold or any dealership of your car’s manufacturer. For example, if you own an Acura, contact the service or parts department of any local Acura dealership. In some cases, you can find the radio unlock code from partnering dealerships — such as Honda for Acura, Toyota for Lexus, and so forth. To provide you with the radio security code, you’ll need to provide proof of ownership, such as your vehicle registration for security purposes.

4. Contact a Local Automotive Audio Installation Center

If none of these resources work for you, the final option is to visit a local automotive audio installation center. Depending on the type of radio you own, they might be able to reset the stereo code for you.

Once you’ve received the security code, it’s relatively easy to enter the code to disable the security function. Most of the time, the code is adjusted by turning the volume or tuner knobs, or preset buttons. The most important thing to remember is entering the code correctly and as recommended by the manufacturer. Your dealership should be able to provide you with the instructions on how to accomplish this step.

Andrew has come to fix my car on two occasions and both times he was on time for the appointment, professional , and extremely thorough in his examination of my car and diagnosis. He is honest and straightforward as to what my vehicle actually needs done immediately, and what I can hold off on for awhile. Money can be tight sometimes, so I do appreciate that. I highly recommend this mechanic!
