A chip key can make your car more efficient than ever before. It not only provides security from the intruders but also performs a number of functions in your car which makes it a must have tool for your car.
A microchip resides in the top of the key has a code number which is uniquely defined to each car key separately. The chip key has a digital chip for identifying radio frequency which is securely embedded inside its head. Control units of the chips send a request to the vehicle to confirm the encrypted coding. The corresponding device in the car receives the radio signals and checks whether the code is the right one. If the car is not able to read the signals of the chips, it will not respond. This ensures that no one can access your car with another set of keys. Even if a thief breaks into your car and tries to hotwire it, it will not start rather trigger an alarm and notify you through your key.
