I don't know what to do!! Please Help!!

Answer
Julia,
I believe you need the factory keyless entry remote (fob) to disable the alarm if turning the key in the door does not work. The factory alarm works when the doors are locked and unlocked by remote, ONLY. There is no simple wire to ground in this case to disarm it.

You may need to replace the OEM key fob from Mitsubishi, else contact your local dealership's service department.
Good luck!
