Question edited for a little more clarity.
Question moved to model category.
This site doesn't do well on abbreviations. By 'acc' (I changed to 'ACC', do you mean the Accessory position on the ignition switch?
Is the key worn out, is a recut key? Can you start the vehicle? You can try spraying Switch Cleaner into the lock.
