Is this a KOS system (the vehicle can be started with the key in your pocket, or a traditional RKE system (metal key that must be inserted into the column to start the car, with remote buttons built into key)?
The instructions for fixing your problem, and the requirements to do it yourself, are different depending on the system.
Let me know which system you have so we can see about getting you fixed up.
I have a tradional RKE system with metal key and built in buttons. None of my keys (2) can remote unlock my car, but they can start the car. At the beginning, only one of my keys could unlock and lock the car, but it suddenly stopped.
The procedure sent by you could not help me.
This is a relatively easy one to program... however I am moderately concerned that your keys both stopped working, potentially indicating there may be another issue at hand.
I will provide your programming instructions for you however as an opening step.
Give me a few moments to organize the instructions for you (I need to go to another location to do this). It will only be a few minutes.
3. Connect the Data Port terminals 1 and 4 with a jumper wire, leave the jumper wire connected, and turn ignition switch ON within 5 seconds
5. Press the LOCK button on the remote key to be registered three times within 10 seconds. The door will lock and unlock once.
7. Disconnect the wire and remove the keys from the ignition.
Yes unfortunately with the upper model system with anti-theft system, you are not going to be able to program a new key without two functioning keys, or taking the vehicle to a dealership or locksmith with Mitsubishi KOS programming capability.
Sorry, I know not the most ideal situation, but rest assured it makes it much more difficult for unauthorized access or stealing of the wireless code that was an issue with the earlier systems.
