This will solve the theft issue but it is likely to cause some VIN mismatch issues. The reason is the BCM pretty much controls this theft system but it needs valid input from the key and other inputs listed below to disarm the system and allow the SKIS system to tell the PCM to start the engine.
Couple options may be cheaper and easier and that is to put all your original parts back on and just get a key programmed to the vehicle.
The other option is to look into getting a PCM that has this system deleted. That way you can just use any key that fits the vehicle and does not require programming. Clearly this comes with concessions as well but it is just a PCM replacement rather then all these other parts.
The reason I would recommend against all this is what if one of these parts has an issue with it? Then you have to use them in order to solve the theft issue but now you need to replace it or fix the new issue which is just going to put you back in the same situation.
If it were me, I would just go back and get replacement keys but let me know if you have questions and we can go from there. Thanks
