Opel radio code
In the factory model of Opel cars (among other things – CAR 300, CAR 400, CDR 500 or CDR 2005), anti-theft protection with 4-digit code was used. In older models, the radio code is assigned to the serial number of the device. In newer models (e.g. CD30), the radio is connected (coupled) with electronic modules in the car. This may be a problem during the replacement of the radio to another model. During service repairs or replace of the car battery, the radio will ask for a code (information: SAFE or CODE on the radio’s display). If we do not have a Car-Pass card with a saved Security Code, we need to search in specialized services.
Some models can be decoded for free remotely (online) or with the use of specialized code calculators. Thanks to the information about the radio’s serial number (the number saved or extruded on the unit’s housing), it is possible to generate the unlocking code with the help of appropriate software.
