Hello,

There is a way to reset the immobilizer if it is activated.
It can be reset by disconnecting the power to engine control module.
Look in the fuse block under the hood, it should have a fuse for the engine control module.
Unplug the fuse for a minimum of five minutes.
That should reset the immobilizer.
Connect the fuse back.
Should be able to start the engine.

Let me know of any questions.
Thank you.
