Solution

1. Preparation

Gather necessary tools:
- Owner's manual (for security code)
- Pen and paper (for writing down codes if needed)

2. Locate Security Code

Refer to the vehicle’s owner's manual to find the radio security code.
This code may also be found on a card in the glove compartment or in the original purchase paperwork.

3. Enter Security Code

Turn on the ignition without starting the engine.
Turn on the radio; it should display "CODE" or "LOCKED."
Use the preset buttons (1-6) to enter the security code.
- For example, if your code is 1234:
  - Press button 1 once
  - Press button 2 twice
  - Press button 3 three times
  - Press button 4 four times
After entering the code, press the “Enter” button if available, or simply wait for the radio to activate.

4. Verify Radio Functionality

Once the code is accepted, test the radio by changing stations and adjusting volume.
If the radio does not unlock, repeat the code entry process or re-check the entered code.
