The immobilizer is not a component that can be removed or bypassed as it is built into the PCM.
You either have a bad transponder antenna or bad key if the key does not work.
Try a system reset to see if the key can be made to work.

If it does not work then a trip to a dealer or locksmith to have new fobs made is about the only solution.
