Solution

1. Preparation

Gather necessary tools: OBD-II scanner (optional), multimeter, and the owner's manual.
Ensure the vehicle is parked in a safe location with the engine off.

2. Retrieve Radio Security Code

Locate the radio security code in the owner's manual or on the Honda website by entering your VIN (Vehicle Identification Number).
If you cannot find the code, contact a Honda dealership with your VIN for assistance.

3. Enter Radio Security Code

Turn on the ignition without starting the engine.
Turn on the radio; it will display "Code" or "Enter Code."
Use the radio preset buttons to enter the security code:
- For example, if the code is 1234, press "1" then "2" then "3" then "4" on the preset buttons.
After entering the correct code, the radio should unlock and resume normal function.

4. Reprogram Settings (if necessary)

Re-enter any previously saved radio presets.
Set the clock to the correct time.
