The engine immobilizer is a device which prevents the engine from starting if an incorrect key was used. Subaru keys are especially equipped with a specific code, which the engine reads and compares to the stored and registered code. If the code on the key does not match the one stored in the system, then it will not start and vital engine parts like the ignition, starter motor and fuel system will all be disabled, making it literally impossible to drive. The engine immobilizer technology also prevents other theft techniques like re-wiring because the system cannot be deactivated. Needless to say, your car cannot be taken away as long as you have the key with you.
Meanwhile, the DataDot anti-theft system works via a license verification code etched to the car, making it almost impossible to change the identity of the stolen cars. The police can simply match-up the code with the plate, and if it doesn't match then the stolen car is immediately reported. Subaru is in fact so confident with this system that they are willing to pay the theft insurance excess if ever the stolen car is not returned to the owner within 45 days.
If ever you wish to further upgrade this already stunning system, you can simply add other security measures like tracking systems and steering wheel locks after you purchase a car from established Covington, LA car dealerships like Baldwin Subaru, in order to ensure that your new set of wheels will not be taken from you so easily.
