A car radio code is a short string of numbers associated with a security feature found in some head units. If your radio is flashing CODE, then it has that feature, and you’ll have to put the code in if you ever want to use your stereo again. Most head units have a memory keep alive feature that allows the radio to remember the time, presets, and other information. This information is all lost if the battery ever dies or is disconnected, but for most head units, that’s the extent of the damage. However, some head units also include a theft deterrent feature that causes them to stop working if they lose power. That means if a thief ever steals your radio, your radio will theoretically become a worthless paperweight as soon as he cuts the harness. Unfortunately, this feature also kicks in if your battery ever dies, which is what you’re dealing with right now. In order to get your head unit working again, you’ll have to locate the proper car radio code and input it using a method that is specific to the particular make and model of your stereo.

You may come across keep alive devices that are designed to prevent the radio from requiring a code after the battery has been disconnected. These devices typically plug into the cigarette lighter, and they provide a limited amount of power to the electrical system while the battery is disconnected. While these devices typically work just fine, they do pose the danger of creating an electrical short. If you plug one of these devices in when replacing a battery, the positive battery cable contacting any ground will cause a short. Additionally, a lot of work that requires the battery to be disconnected has to do with components that can be damaged if they are hot when you unplug or reconnect them. So while these keep alive devices are handy, they should be used sparingly and with great care.
