How Do I Reset a Locked Radio on a 2002 Volvo S40?

Updated February 21, 2017

Appearing in 2002 in Dark Blue and Bamboo Green, the Volvo S40 offers a few package options, which include a power driver's seat, power sunroof, leather upholstery and an emergency boot release. The 2002 Volvo S40 also provides you with a theft-proof system for your car radio to prevent unauthorised users from operating it. Resetting your radio, when it locks, will take just a few minutes of your time.

Obtain the four-digit radio code that came with your 2002 Volvo S40 at purchase. This radio code is on a card that looks like a credit card. When you turn the radio on, the radio display will show "Input CODE ****."

Contact your local Volvo dealer if you cannot find your four-digit antitheft code for the radio. The dealer can find it in a database. You may need to drive to the dealer so they can cross-reference your radio's serial number. Make sure you bring proof of ownership, such as vehicle registration and your driver's license. (See Reference 2)

Rotate the "1-20/Disc" knob on the radio to select the first digit of the four-digit code.

Push the knob to enter your selected number. Rotate the knob and push it in to select each of the remaining digits of the code.

Re-enter the correct radio code from the beginning if you enter an incorrect code. An "Error" message will display on the screen if you make a mistake. Your radio will lock for two hours, displaying the message "Off," if you make three errors trying to enter the code.

Re-input the code after two hours. The headlights must be turned off, and the ignition key turned to the first position, "I>L1" during the two-hour wait.

Store the four-digit radio code in a safe location. Do not keep the radio code inside of your car.

Tip

You must reset your radio antitheft code whenever you disconnect your car's battery. You must also reset the radio code if you pull up the yellow fuse holder to remove a blown fuse.
