Maruti introduces Immobilisers across all models. Do you get sleepless nights worrying about the security of your car…that it might be stolen?? Well, if you are planning to buy a Maruti car now, then you can sleep away to your heart’s contentment without fretting about your car’s security anymore। Maruti Udyog, the biggest car-maker in the country, has introduced the engine immobiliser system as an option on all its models to prevent their theft. The introduction of immobilisers has been brought about by an increase in cases of car thefts. Once a car is lost, its recovery is very rare. So, security systems have become a necessity for cars.
The incorporation of engine immobiliser in a car will increase its price slightly but at least it’s better than losing the car itself. And anyway, the hike is going to be minimal, just about Rs. 3,000-3,500. People would not mind shelling out that extra amount for a device which will guard their car. But how an immobiliser can prevent a car’s theft, you might wonder. Here’s how…An immobiliser is a chip that will immobilise the car’s engine if it is not opened with its original key. It is the technique of cryptography that makes an immobiliser work. Actually, the car’s steering column has a base station unit, in which lies a chip. There is a similar chip in the car key as well. When the original key is inserted into the car’s key-slot, it transmits wireless message to the steering’s base station unit. The chip in the base station unit then uses a unique secret code to read this message.
If the message transmitted by the key’s chip matches the one stored in the base station unit’s chip, the car key is allowed to rotate and activate the starter motor। However, if the key fails to transmit the message or if the transmitted message and the one stored in the base station unit’s chip do not match, the connection between the key and starter motor is broken and the car does not start.
What’s more!! Even if the thief tries to figure out the exchange of wireless messages between the original key and the base station unit, it will be impossible for the thief to decode what’s there in the chip।
In case a car is tried to be opened repeatedly with a wrong key, the chip locks the Electronic Control Unit (ECU) of the car. Once it is locked, the car will never start, till the original key is used. So much so for the immobiliser… Sure, it will take care of your car’s security but that does not mean that you become reckless in performing your duties towards your car’s safety. Always park it in a safe place, roll up its windows and lock it properly. And yes, always keep its keys carefully.
