I am having problems with my 2004 pacifica. My ignition switch fuse blew and car would not start. Once I replaced it, the car still would not start and now just says "system immobilizer" every time I try to start the car.

That sounds like an issue with the security system. I hate to say it, but you need a dealer that has the proper test equipment to check it. Otherwise, you will be replacing parts that are good.

The key has a transponder programmed to the ignition switch. You might have to take the car to a dealership to use a DRB III scan tool to reprogram the computer to accept the key. I attached an image to relearn the key so you can try that and let me know if it works.
