A car radio code is a brief series of digits connected to a security function that some head units have. Making a stolen head unit unusable when it is unplugged from the battery serves as a barrier to theft. Still, if your battery runs out, this feature activates. Either way, you must enter the code to get the head unit operating again. Usually, the radio will flash “CODE” to let you know.

How to Find the Car Radio Code of Your Car
These are the primary methods, listed in decreasing order of difficulty and expense, for finding an automobile radio code.
Check the Owner’s Manual
The owner’s manual may contain the automobile radio code in some circumstances. Since most people keep their manuals in their cars, this isn’t a very safe place, although some manuals have a designated spot for them. Your car’s previous owner may have entered it there if you purchased it used.
Visit the websites of the manufacturers
Visit the websites of the stereo manufacturer and your car manufacturer. Car radio codes may be stored in online databases by companies. You may be able to get the code you need by entering information like your vehicle identifying number (VIN) or the serial number of the radio.
Some free databases provide codes for different kinds of radios in addition to OEM databases.
Speak with your dealer
Any dealer should be able to assist, regardless of which one you purchased your vehicle from. Get the serial and part numbers of the radio out of your pocket, together with the make, model, year, and VIN of your car.
Pay for a Service
You will have to pay for a local or internet service that has access to a database of vehicle radio codes if none of those solutions work. Usually, they want the radio’s part and serial numbers, the brand and model of the radio, and the make and model of your car.
Tip: Once you’ve located your code, write it down and store it in a secure location with easy access.
Inputting the Code
The process for inputting the car radio code varies depending on the stereo’s make and model. Generally, choose numbers using the volume or tuner knobs or buttons, then click the knob or press another button to move forward.
Instead of entering a code, some sound systems and late-model cars need you to press a series of buttons.
Warning: Entering codes too frequently could lock you out, so proceed with caution. You will then need to finish a reset process. Sometimes you have to unplug the battery once again and leave it that way for a while. In other situations, you have to switch on the radio, turn on the ignition (without starting the engine), and wait a while. Consult your car’s owner’s manual as the process may differ.
Devices for Battery-Powered Memory Keepers
Devices are known as memory keepers, or keep alive, stopping the radio from requesting a code once the battery has been removed. When the battery is disconnected, these devices, which usually plug into the cigarette lighter, give the electrical system some limited power.
These devices are dangerous for the electrical system even though they usually function well. When one of these devices is plugged in to replace a battery, for instance, a short circuit will occur if the positive battery wire comes into touch with any ground (such as the negative battery cable, the frame, or the engine). Read the instruction booklet attentively since there may be other precautions to be aware of.
