There are lot of security arrangements possible. however fuel cut is best among all
1.It is plug and play. You don't need to cut even a single wire. Installation is very easy.
2.With this system, car is now having Hand-free key-less entry. you just need to go near the car with a remote in your pocket and the door will unlock and vice versa.
3.It has a pushstart plus remote start. Go near the car , doors unlock automatically, just sit on driving seat press the push button and engine starts and your remote is still in your pocket.
4.Remote start. In a hot weather, your car cabin gets hot if you park your car in direct sunlight. You just need to press a button from your car remote while sitting in your office and engine of your car starts with closed doors and your car AC starts too if you set it in an ON condition before. Same goes for a cold weather. :)
5.Protection. It has a two way Communication protection. The remote will start beeping in your pocket if someone is trying to have some chitchat with your car :D and displaying which door has been opened by someone. It also has RFID system so no one can start your car without remote and for any instance, someone is trying to break/uninstall/cut any wire of this system then the system will kill your engine instantaneously.
