New York City Locksmith Automobile Keys Programming New York, NY
How does remote programming work?
The key fob or head of all modern automobile keys come embedded with a microchip. When you press the button, the microchip emits a unique code that is received by the car’s electronic control unit. Upon verification, the car’s ignition gets activated to allow access. In case a wrong code is provided, the immobilizer in the car locks down the system and refuses access. Modern automobiles contain microchips that send a different code each time you access the car to ensure that no thief can copy the code to gain access.
