I asked the person for details and.here is the reply
At system arming through remote or in gun point robbery, the petrol, self, ignition, fuel-pump, cdi, efi, fuel valve are automatically disabled. One can not start by any hot wire connection. In addition to it the system can not be disabled by cutting any or all of its wires. In all such cases vehicle is completely immobilised. And on contrary all systems (whatever) available in market can be bypassed by cutting , just a single wire and can also be started by hot wire connection.
