Dacia Logan radios are usually Renault-based units, so the precode method is very common. CODE or SAFE appears after battery replacement or complete discharge.
Quick answer: identify the exact radio input required by your unit before entering any code. Renault and Dacia usually use a precode; Ford usually uses a serial number.
How to unlock it safely
Hold 1 + 6, note the precode, calculate the unlock code and enter it using the number buttons. Confirm with the correct key for your model.
- Turn the ignition on and power the radio.
- Display or read the precode/serial number.
- Use the correct calculator for that input format.
- Enter the four digit code carefully and confirm it.
Important notes
Save the code after unlocking. It will remain the same for that radio.
Warning: avoid repeated random attempts. Many OEM radios lock temporarily after several wrong codes.
When the online method may not work
The calculator method is intended for supported OEM units. It may not work for aftermarket radios, VIN-paired multimedia systems, damaged displays, locked dealer-only units or radios that have already been replaced with a different model.
