If you are refering to an aftermarket system, then you simply remove the aftermarket equipment from your vehicle and restore the vehicle to the original configuration that the vehicle was designed with.
If you are refering to the factory installed vehicle theft system (door locks and alarm), there are some parameters that can be reprogrammed. However, there is no way to disable the system without also disabling features that are required to make your vehicle run.
