Hi Im David, thanks for using the site. allow me a moment to look up some information on your issue. thank you.

Expert:  david craig replied 7 months ago.

first of all do you have another key?

Expert:  david craig replied 7 months ago.

hello?

No
No
Expert:  david craig replied 7 months ago.

Look on your drivers B pillar, just behind the door. You should see a sticker that has "serial number" written on it. The sticker is about 1" x 2".
Provide that serial number exactly as it appears and I can provide your temporary over ride code for you and instructions on how to use it.

I did lose the key and had a locksmith make another will this make any difference? I do have the key code from locksmith
Expert:  david craig replied 7 months ago.

The key code is not what i need. i need the immobilizer code at the location i provided above.

Expert:  david craig replied 7 months ago.

your immobilizer over ride code should be

5669

To input the code you will use the brake pedal in the sequence shown below from the original owners manual insert. Please note that timing isabsolutely critical. If you take too long between steps or rush it will not process correctly.
Also please note that this is meant to be done with a flat metal key only. If you are using a transponder key (whether new and unprogrammed or programmed incorrectly etc) it will not work. This is because when the system sees an RFID signal it automatically disabled the over ride. You can get around this by wrapping the head of the key in aluminum foil several times to shield the RFID signal.
Once you perform the over ride the engine will start, and then you will have one more start after that before it locks again. so you need to drive it right to the dealer to have new keys programmed.

Thank you, isn't there anyway to just get rid of the immobiliser?
Expert:  david craig replied 7 months ago.

this above procedure may or may not work if you dont have a spare key. as a professional licensed technician i am not allowed to give any tampering advise/direction..i beleive there are videos of things like that.

Customer: replied 7 months ago.
OK thanks I do have a regular blankie and I and I hope it works
Expert:  david craig replied 7 months ago.

if not call the dealer give them that # you gave me ans see what code they come up with.

Customer: replied 7 months ago.
Okay I tried the number and it didn't work and then I called the Mitsubishi guys and they said they don't give it out over the phone and I can't really afford to have my car towed up there can you check and make sure there's not another number that might work for my car or some other way I can get it started

Expert:  david craig replied 7 months ago.

Customer: replied 7 months ago.
No the dealer is on the other side of town and my car , well you know so don't know what to do
Expert:  david craig replied 7 months ago.

Customer: replied 7 months ago.
the bypass code he gave me didn't work.
Expert:  Amedee replied 7 months ago.

Is your key all metal or does it have plastic on or around it?

Customer: replied 7 months ago.
All metal and a plastic one
Expert:  Amedee replied 7 months ago.

So you have two different keys?

One is plastic and one is metal?

Customer: replied 7 months ago.
Expert:  Amedee replied 7 months ago.

Thank you for that information. This problem is either caused by a bad key or a bad security module provided the inputs are correct. I would start by checking all fuses under the hood and inside the vehicle and then check the inputs to the security module and replace it as needed. Once it is replaced, it will need to be programmed and or the key will need to be configured to the vehicle or new security module and you will be good to go!
