Immobilizer System

When you put the key in the ignition, it sends an identification code to a receiver inside the car. If the ID code matches that in its memory, then the car’s computer will let the engine begin. If the ID code does not match, an immobilizer is activated, which stops the car from getting started.

This technology isn’t 100% secure however it does work even in the event you lose your keys. It is possible to “hack” an anti-theft system using radio waves. The thief could use an aerial antenna to spoof the signal to inform that the car has the key in the ignition.

To avoid this experts are developing more secure systems. Some provide WiFi connectivity with undetectable installation as well as pin code entry via dashboard buttons. Thatcham Research has developed a system of grading and approbation for buyers to evaluate products.

If one blows up, the replacement can be purchased from an auto parts store.

Key Blade
