The radio in your 2001 Mitsubishi Eclipse uses an auto-locking feature so that whenever power is cut to the radio, the radio will lock. This feature helps prevent unauthorized use of your Eclipse's radio. It also acts as a deterrent to theft, since the thief can't use your radio, even if they were to steal it. However, if you are working on your Eclipse, and you need to disconnect the battery, you will need to know how to enter the code on your 2001 Eclipse so that you can use the radio again.
Turn the ignition key to the "II" position and turn on the radio.
Wait for the words "CODE" to appear on the digital display of your 2001 Eclipse.
Enter the radio code given to you by your Mitsubishi dealership using the numeric keypad on your Eclipse radio.
