stranded-remote start and immobilizer light

Hi, I have an aftermarket remote start on my 2019 tundra. I recently used it, then entered my car. With this particular remote start, it requires you to step on the brake which turns off the engine, then I can use my key as normal. I forgot the step on the brake, and put the key int to start. This apparently did something so that my engine light (red immobilizer) turned on and now I am unable to start the car. I have tried unlocking, etc but no luck. I was hoping for some suggestions to get the truck started again....
