Three simple steps to unlock your car radio
Remove the radio from the dashboard (or check the screen by holding a button). The serial is printed on the sticker on the chassis, or shown after holding a preset button for 3 seconds.
Choose the radio manufacturer from the dropdown — not the car brand. Check the front panel or the label on the radio unit itself to identify the make and model series.
Your code appears instantly. Use the station preset buttons (1–4 or 1–6) on the radio to enter each digit, then confirm. Your radio will resume normal operation.

All modern car radios include an anti-theft system: when the unit loses power (battery replacement, accident, repair work), it locks and asks for a PIN code. Without the correct code, the radio remains disabled — making it worthless to a thief.
The serial number (also called "Security Code Reference" or "Unit Serial Number") is usually on a white or silver sticker on the side, back, or top of the radio unit. You may need to remove the radio from the dash using release keys. Some radios also display the serial on-screen by holding a button for 3–5 seconds.
Our database covers the most common OEM and aftermarket units. For brands not listed (Alpine, JVC, Pioneer, Kenwood, etc.), the unlock code is usually available from a local dealership or the radio manufacturer's website with proof of vehicle ownership.
Most radios allow 3–5 incorrect attempts before entering a lockout mode. Leave the ignition in the ON position (without starting the engine) for 30–60 minutes to reset the counter. Do not try another code until the timer has expired. Always confirm you have the correct code before entering it again.
Yes — completely free, no registration, no limits. The database contains codes obtained through legitimate reverse-engineering of factory radio databases. You are responsible for confirming you own or have authorization to unlock the vehicle.
This can happen if: (1) the radio was previously programmed with a custom code by a dealer or previous owner; (2) you selected the wrong brand variant (e.g., Ford M vs Ford V series); (3) the serial was entered with an extra leading character. Try the other variant for your brand, or contact a dealer for a direct read from the radio's EEPROM.
