Have a 2007 Mitsubishi Raider won't start changed starter took after market alarm system out had locksmith come out to make new key he was able to plug into ECM get code but would not read old or new key
Based on the information you have provided, it sounds like the problem with your 2007 Mitsubishi Raider is likely related to the immobilizer system. The immobilizer system is a security feature that prevents your car from starting unless it recognizes the correct key.
When you had the locksmith come out to make a new key, they were able to get the code from the ECM, but they were not able to read either the old or new key. This suggests that there is a problem with the immobilizer system itself.
There are a few things that could be causing this problem. One possibility is that the immobilizer chip in the key is damaged. Another possibility is that the immobilizer module in the car is defective.
To diagnose the problem, you will need to take your car to a qualified mechanic. They will be able to scan the car's computer for error codes and test the immobilizer system. Once the problem has been diagnosed, they will be able to repair or replace the necessary components.
Here are some of the common causes of immobilizer problems:
Damaged key
Defective immobilizer module
Faulty wiring
Corrupted software
If you are having trouble starting your car, it is important to have the immobilizer system checked as soon as possible. Driving with a malfunctioning immobilizer system can be dangerous, as it could allow someone to start your car without the correct key.
Here are some tips for preventing immobilizer problems:
Keep your keys in a safe place and avoid dropping them.
Avoid exposing your keys to extreme temperatures or moisture.
Have your immobilizer system checked regularly by a qualified mechanic.
