In my opinion, your Chevy Tahoe should start if you're using the right key, even if you're not unlocking it with the key fob. If it's not, it could be because the alarm system needs recalibrating or rewiring after removing the aftermarket system. I'd start by checking the wiring and programming, and maybe try resetting the system if needed.
