Hi,
When you replaced the PCM, did you have the keys reprogrammed to match?
The PCM stores the immobilizer key data, and if you change it out without reprogramming two major problems occur:
1) The key data is lost, so the car does not recognize your key
2) The PCM and immobilizer ECU are no longer paired, locking the system out entirely.
