How to Reset Your Car Radio Without A Code?


Are you struggling to reset your car’s radio system? If so, don’t worry too much. In this article, we will look at various methods for resetting a car’s radio without a code, along with the precautions that must be followed while doing so.  

Sometimes we notice that our car radio is locked and asks for a “CODE” to restart. Usually, this is a common occurrence if the car recently had its service, other settings restored, or the battery got replaced (or) repaired. Basically, your car radio displays “CODE” on the screen, asking you to enter the security code to reactivate the head unit at this point.  You must enter the security code to access your car’s audio system. This is where the radio codes come into the picture.

What are Car Radio Codes?

The car radio codes are a unique short security string of numbers associated with the security feature. These codes are designed to avoid the theft of your car’s audio system. They are used to unlock the car radio system when the power is lost (or) the radio is removed from the car. This security feature also kicks in during battery replacement (or) when the battery is dead (or) disconnected (or) stolen. 

Why Do Car Radios Need Codes to Reset?

Car radios are a vital component of any car audio system. Car radios need a short security code to unlock if the car battery is disconnected, stolen, (or) replaced. The main purpose of radio code is to prevent theft and discourage thieves from stealing car radios because they can neither use nor sell them. Moreover, you will not be able to access the car audio system without a code. Simply, enter the security code when your car radio flashes “CODE” on the screen to unlock the car radio.  

Methods For Resetting A Car’s Radio Without Code

Here are some methods for resetting a car’s radio without code. Walk through them to learn more. 

1. Refer to the User’s Manual (or) Guide

In some cases, you might find radio code in the owner’s booklet. So, check your car’s user manual (or) guide to find the radio code. This book is often found in the glove box. Usually, all the information including regular maintenance updates, servicing recommendations, and guidelines on how to operate each system on your car are clearly mentioned in the owner’s manual. Look for the index at the back and read the security section (or) radio/stereo section to find out whether the manufacturers provided any radio code data. 

Note: If you bought a used/second-hand car, don’t forget to collect the radio code from the owner for future use. 

2. Reach Your Local Dealership

Visit the local dealership from where you have purchased the car (or) the local dealership of your car’s manufacturer and provide them with the car model, make, and vehicle registration details to get the radio code. You can also get a radio code with VIN number at the local dealership.

3. Visit The Manufacturer’s Website

Many automobile manufacturer websites now offer an online database that allows you to obtain car radio codes (or) get them in the mail by just submitting your vehicle model, make, vehicle registration, and VIN. 

Note: This would be completely useless if you have an updated car radio system. Rather visit your nearby local stereo manufacturers. 

4. Contact a Local Stereo Installation Center

Various online code-generating tools are readily available to reset your car radio. Be careful while using them, as they may not be reliable and safe. Make sure the website you’re using is credible and trustworthy.

9. Battery Memory Keeper Devices

Memory keeper devices prevent the radio from asking for a code even after removing the battery. When the battery is disconnected, these devices normally plug into the cigarette lighter and supply limited power to the electrical system. 

10. Bypass Car Radio Codes

Start your engine and turn on your car’s audio system. Turn it off if it asks for “code”. Press and hold the radio button for approximately 40-50 minutes. During this interval, your car’s audio system will ignore the code and start playing music.

11. Contact Customer Care Support

Several automobile companies offer various customer care services including live chat, phone, and email features for instant support. Provide them with parameters such as the car model number, year, serial number, and so on. They might provide you with suitable car radio code based on the radio type.
