Delphi uses a different algorithm. | | Wrong algorithm version | Some early Blaupunkt 1 units use the "Old" algorithm. Try an "Old" calculator. | | Radio is from a different car | The code is tied to the radio serial, not the VIN. The calculator is still correct. |

Once your radio is unlocked, save the code in three places:

If you ever replace your car battery, the radio will revert to "SAFE," but you will have the code ready.

Write this number down exactly. One wrong digit will generate an invalid code.

Once you have the 4-digit code (e.g., "1532"), follow these steps precisely:

Warning: You have 3 attempts to enter the correct code. On the 4th failed attempt, the radio will lock for 1 hour (display "SAFE" and a countdown timer). Do not turn off the ignition during this lockout period; leave the radio on until it resets.
