Changed and programmed key sentry immobilizer and now engine doesn't want to turn on?

Let's run the codes to see if the reprogram is successful, you can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

here is a video to show you how:

Here is information on the system on how to reset it, please check the images below:

Conventional diagnostic methods may not prove conclusive in the diagnosis of the Sentry Key Remote Entry Module (SKREEM), sometimes referred to as the Wireless Control Module (WCM), and the Sentry Key Immobilizer System (SKIM), sometimes referred to as the Sentry Key Remote Entry System (SKREES), the ElectroMechanical Instrument Cluster (EMIC), the Powertrain Control Module (PCM), the Controller Area Network (CAN) data bus, or the electronic message inputs used to provide the electronic features of the SKREES. The most reliable, efficient, and accurate means to diagnose the SKREEM, the EMIC, the PCM, the CAN data bus, and the electronic message inputs for the SKREES requires the use of a diagnostic scan tool.

I have also included how to change the ignition key/immobilizer in case you missed a step. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.
