Yes, you can modify the settings on a Mitsubishi Navigation System to make all the doors unlock: Then select Power Door Locks > Unlock Operation under SET > Equipment. Using the buttons on your FAST-key fob, you can still modify the settings if you don’t have a navigation system:
- First, hold down the Lock #1 button.
- Step 2: Press and hold Lock #1 for four seconds, then press and hold Unlock #2 for four seconds (do not allow more than ten seconds to pass).
- Step 3: Continue to hold both buttons down, and then let go of Lock #1 first.
- Release the Unlock #2 button second in step four.
