Mechanical Keys

You can still buy mechanical car keys, the ones that you put into an ignition lock cylinder to start your vehicle. If your car has one of these keys, replacing the fob and keys is fairly inexpensive (if they get lost or stolen).

A spare key is crucial because modern cars won't begin when a key that isn't programmed with the proper chip is used.

Transponder keys are similar to mechanical keys, but they have an electronic chip hidden in the base. The chip communicates with the computer system in your vehicle. Your car will recognize the code contained in the chip and accept it, however it will refuse to start if any other code is used.

The key chips are programmed with a serial number that is unique to your vehicle. When the key is inserted into the ignition, the serial number is transmitted to the immobilizer of the car and checked to ensure that it matches up and allows the engine to run. This security feature can only be blocked by a specially designed device that can read the chip to match it to another vehicle.

The shaft of the key is thicker, which is another sign that this is not a regular car key. Locksmiths generally make use of milling tool to cut these types of keys. vehicle key replacement is similar to a drill bit, and is designed to remove metal in very precise angles.

These are among the most secure keys you can get for your car, as they are extremely difficult to duplicate and only cut by a dealer or a licensed locksmith.

Smart keys communicate with the vehicle via radio-frequency identification (RFID) instead of the conventional single piece of carved metal. They come with a chip with an individual code, which is encoded on every key. When you open your car doors or pop the trunk key, it transmits a signal to your vehicle's computer onboard. The computer then prompts the appropriate frequency and allows you to connect to your car and begin it.

The chip inside the smart key is equipped with several security features to protect it from theft. First the key emits a very low-frequency signal that can't be picked up by any receiver other than your car. If the computer onboard detects this signal, it will display a different one that is a unique sequence that only your car can recognize. This prevents a tech-savvy criminal from using an external pulse generator to "fool" the system and create the key function for other vehicles.

In addition to locking and opening the car, some smart keys also have additional functions like storing specific driver preferences remotely opening windows, the sunroof, among others. These are accomplished by activating the key's proximity sensor, pressing a button on the key itself or, in certain cases, twisting a small metal part inside the key.

Certain key fobs are opened by placing the dead key in a slot, or by placing it next to an inductive coil that is located on the dashboard. Some key fobs feature a mechanical (fully emergency) key blade in the key.

Replacing a smart lock usually requires a visit to the dealership, who will either have the replacement on hand or make it available for you to purchase.
