Ok, roll a window down then lock all of the doors except the drivers from the inside, then close and lock the drivers door with the key wait at least 30 seconds or longer, then using the key unlock the drivers door, that should deactivate the system. HTH

Try running the disarm protocol listed in the owners manual first, if that don’t work then try this: from the inside manually lock all the doors except the drivers, exit the vehicle with keys in hand, close and then using the key lock the drivers door, remove the key and wait at least 1 minute, then using the key unlock the drivers door and see if it will start. If this fails then you most likely have a door switch that will is not operating, so that means that means that you will need to find a shop that knows this system and can do a good diagnostic.

You didn't get all of the security system, it's has went into full active mode, the only thing to do is put back the sensors and wiring and then you will need a dealer or a smart locksmith to reprogram the security system recognize the new components. I recommend a locksmith as it will be a lot cheaper than the dealership.
