Key Programmers
Modern automobiles require a key-programming procedure to start the vehicle's system and then start the vehicle. In some cases the key will have to be programmed by an auto locksmith or a dealer.

This is why it's a good idea to always have two working keys for a modern automobile and to have the replacement key programmed if required.
A keyprogrammer can reprogram the transponder chip of the new mechanical key or key fob. It is also able to clone data of an existing key and allow duplicate keys to be made. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software, which allows them to communicate with a computer. They also feature a bidirectional user interface for working with an immobilizer system.

Transponder Chips
Transponder chips can be found in cars manufactured within the past 20 years. It's a small piece of plastic on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the car's computer system to confirm that the transponder chip inside the key is the right one for your specific vehicle.
This prevents the vehicle from being started by hot-wiring, or by tampering. The chip inside the key verifies that the owner is the person who owns the vehicle. This helps to prevent car theft.
Transponder keys look like normal keys but they have caps made of plastic. The chip is contained within the plastic portion of the keys. There are several different cuts: a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will be taken up by the chip and cause it to send a signal back to the car. If the computer in the car detects the signal as being correct, it will disable vehicle immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as being the correct one, it will prevent the engine from running and will notify you by flashing its lights and sounding a siren. This function is designed to discourage people from tampering with the vehicle. However it isn't a foolproof measure of security. A skilled and committed thief could still be able to bypass this system by using a special device to intercept the signal.
As you can see, there are quite a few advantages to getting transponder keys. This is something that all car owners should consider if they want to protect their investment and reduce the chance of theft.

In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate the car in a parking space, today's key fobs can also turn on the heated steering wheel or roll down all windows with just a single click. A lot of these additional features may appear convenient however they could make it more difficult to keep the track of your car keys.
Key fobs utilize radio frequencies to communicate with one another and the car. These frequencies are transmitted via a small antenna that is located in the middle of the key. The communication is encrypted, which helps to stop others from stealing and re-transmitting the signal.
You can program a keyfob in different ways based on the model and brand of your vehicle. Certain models allow you to do this by yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order for them program a replacement key fob or an additional one.
When you hit the button on a key fob the microchip inside sends an informational code to the car's radio that it is linked to. car key fob programmer compares this information with the 'allowed' signals stored on the fob and either opens or locks the door. If the data doesn't match an chirping sound is heard and the car isn't allowed to operate.
Once the car has been associated with a particular fob, it only accepts signals from the device. Other fobs won't work with the car, despite the fact that they appear identical. This safeguards the integrity of the computer system of the vehicle and stops unauthorized key fobs gaining control over it.
Most newer car dealerships will only accept cars with original fobs, or genuine replacements offered by the manufacturer. It is because the only place with the expertise to prepare the replacement fob is the service department of a dealer. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by customers without the need for an authorized dealer.
