Our customer opted for this system after having his previous vehicle stolen. The unfortunate thing is most of our customers don't know how common car theft is until it happens to them. We programmed this system so that if the tag isn't present then the vehicle will simply not start. However, we can also program this system to only start once when the tag is absent. The immobiliser module is also wireless so there is no wiring running to the tracking system making this system one of the most secure that we do.
