Bhai plug and play means that it fits grip to grip, No wire need to cut. It is not a usb for plug and play . if car lifter will cut any wire then system will kill the engine instantaneously. First Car lifter have to study the system by wasting time then to do some alteration, he still needs to open steering wheel plastic with screwdriver but when he will do something with ignition grip then fuel will be cut off to engine (hope car lifter is not reading this explanation ).
On a straight line of sight range is 300 to 500 meter. I personally checked it till 200 meter.
Obviously if i am not in the range then how could the remote will get the signal for beeping. Check other two way communication security system in the local market and compare their ranges to its range.
