How to enter your radio unlock code

Once you have your unlock code, entering it usually takes under a minute. The exact buttons vary by radio, but the process is similar across most vehicles.

The general steps

1. Turn the ignition on so the radio powers up (it may show CODE, LOC, or 0000).
2. Use the preset buttons (1–6) or the tuning/seek controls to enter each digit of your code.
3. Confirm with the SEEK, AM/FM, or ENTER button as directed.
4. The radio unlocks and returns to normal.

With the ignition on, use the HR and MN (hour/minute) buttons to enter your code, then confirm.

Avoiding a lockout

• Enter the full code carefully — many radios give you only a few attempts.
• If you make a mistake mid-entry, finish the sequence rather than restarting, then enter the correct code.
• If the radio shows INOP or "wait," leave the ignition on for about one hour to reset before trying again.
