Unfortunately this was designed to prevent exactly what you are trying to do. If the transceiver module does not see a valid key trying to start the engine then the PCM will disable the engine so that it does not start.
I attached the info about this system and highlighted the important part that is causing your issue. Basically all elements needs to function or the engine will not start.
Your only option is to get a new key and program it to the vehicle.
Sorry for the bad news, let me know if you have questions. Thanks
