How to Unlock a Bosch Radio in Alfa Romeo
Bosch built many of the older Alfa Romeo cassette and CD radios from the era before touchscreen infotainment, often shared with Fiat and Lancia. Each Bosch unit has a serial number on its label that is used to calculate the unlock code. It is that serial on the radio, not the vehicle VIN, that matters.
Losing power, whether from a dead battery, a battery change or electrical work, causes a Bosch Alfa Romeo radio to lock and ask for its code, usually showing CODE or LOCKED. This is normal factory anti-theft behaviour rather than a fault. Pull the unit, read the serial, type it in here and recover your Alfa Romeo Bosch radio code.
A Bosch radio asking for a code is not usually a sign of damage. Most original car stereos include built-in anti-theft protection that requests a security code whenever the battery is disconnected.
If you have the serial number of your stereo, we can help you find the correct unlock code online. Everything can be completed online, so you can reactivate your infotainment system without unnecessary delays.

Help & FAQs
Yes. As long as you have the radio serial number, the radio code can usually be generated online without visiting a dealership.
Once the correct radio code has been entered successfully, it is normally stored in the radio's memory.
The code will only be requested again if the radio loses power.
First, verify that the radio information was entered correctly and that the code was typed into the radio exactly as provided.
If the issue persists, contact our support team so the order can be reviewed and resolved.
Not necessarily. Radio suppliers often vary depending on the model. The quickest check is the maker's label or the serial number on the unit itself.
For most Bosch radios, the vehicle identification number alone is not enough. The correct unlock code is normally generated using the radio serial number, which uniquely identifies the radio.
Most original radios go into a timed lockout after a few wrong entries. You may have to leave the unit switched on for a set time before trying again, depending on the maker.
