Alpine Radio Code Generator [updated]

Enter your Alpine serial number and exact stereo model number into the generator fields.

Most "generators" are actually interfaces for databases that link a unit’s Serial Number to its original factory-set code.

Select a tool or service. This can be a mobile app downloaded on your phone, an online website, or PC software.

Leave your car ignition turned to the "ACC" (Accessory) position with the radio turned on.

Before you can use any generator, you must locate your radio’s serial number. This is not the model number (e.g., CDE-172BT), but a unique identifier consisting of letters and numbers. Method A: Check the Original Documentation
