After getting a new key cut and reprogrammed the car still has power but does not crank over?

When you say it does not crank over do you mean the engine cranks (starter working) but not run? Also, can I ask if the security light is flashing? If so, this is your problem, the security system cuts the fuel pump operation so nobody can steal the car. I would redo the ignition key coding because it sounds like it was not done correctly. Here is a guide to help you reset the system which you can try to see if it helps:
