Key Programmers

Modern vehicles require a key-programming method to set up their systems and to start the car. In some instances the key needs to be programmed by an auto locksmith or a dealer. This is because the key could not function properly, or it will not start the vehicle at all. This is because the key hasn't yet been programmed into the vehicle's system. This can be costly. This is why it's a good idea to always have two keys that work for a modern car and have the replacement key programmed when required.
Keyprogrammers can recode the transponder chip of an entirely new mechanical key or key fob. It can also clone the data of an existing key to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with computers and also provide bidirectional interfaces to work with the immobilizer system.
There are many different types of keyprogrammers on the market. They are available in a variety of sizes, shapes and colors. Some are cheap, while others are very advanced and can cost thousands of dollars. Certain are designed for specific vehicles and can provide advanced diagnostics of the vehicle's electronic system.

Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the last 20 years. This is the little piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then taken up by the antenna that is fitted around the ignition barrel of your car. This allows the car's computer system to confirm that the transponder chip that is in the key is the right one for your specific vehicle.
This stops the vehicle from being started by hot-wiring, or by altering the key. The chip in the car key ensures that the owner is the person who is the owner of the vehicle. automotive key programming helps to reduce the risk of theft from your car.
Transponder keys appear like normal keys but they have a plastic cap. The chip itself is housed inside the plastic portion of the key, and there are a few different cuts that can be found on the keys: a standard cut laser cut (also called a sidewinder), or a Ford Tibbe key.
A circuit within the induction coil emits a signal when the transponder is inserted into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the car's computer detects this signal as the correct one, it will turn off the vehicle immobilizer and allow the engine to begin.
If the vehicle does not recognize the transponder signal as being the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding a siren. This system is designed to deter individuals from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined thief could still be able to get around this system using a device that can intercept the signal.
You can see that a transponder is a great option. This is something that all vehicle owners should consider if they want to protect their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate a car in a parking lot, today's key fobs can also activate a heated steering wheel, or open all windows with a single button click. These extra features can make it difficult for you to find your car keys.
Key fobs make use of radio frequencies to communicate with one another and with the car. These frequencies are sent through a small antenna located inside the middle of the key. The transmission is encrypted, which helps prevent others from intercepting and re-transmitting the signal.
There are a few different ways to program a key fob, based on the make and model. You can sometimes do this yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob.
When you press the button on your key fob the microchip inside sends an encoded code to the car's radio that it is paired with. The receiver then compares this information with the 'allowed' signals in the fob and then either opens or closes the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't allowed to operate.
Once the car is paired with a specific fob, it can only receive signals from that device. Other fobs will not work with the car, despite the fact that they look like. This safeguards the integrity of the computer system that runs the car and prevents the use of unauthorized key fobs to gain control of it.
Most newer car dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially those for older models that have less advanced systems, can be programmed without the need for a dealer.
