Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
Pretty much anyone can cut the key to match yours but to get it to start the car you will need to have it programmed.
Do-It-Yourself programming is not available for this vehicle. This vehicle requires a diagnostic scan tool to be connected to the vehicle to program the key. You will need to find a local automotive locksmith or a dealer to program it. I would probably go with the locksmith as it will be much cheaper.
Are you sure they aren't referring to the key cut code? If you don't have a key to copy then you will need a key cut code- only the dealership can get that for you and they usually want to see proof of ownership before they will give it to you- a title, or registration in your name.
Other than that a locksmith shouldn't need any other codes to program the key.
You don't have a key to copy?
Oh yeah. That's bummer. Only the dealer can get you that key cut code. They are very protective of them.
