Key Programmers

Modern cars often require a key programming procedure to set up the car's system and allow the car to start. In certain instances the key needs to be programmed by an auto locksmith or dealer. This is because the key could not function correctly, or it will not start the vehicle at all. This is because the new key has not been programmed into the vehicle's system - and this can be very costly. This is why it's a good idea to always have two keys working for a modern car and to have the replacement key programmed when required.
Keyprogrammers are devices which can reprogram the transponder chip in the form of a new mechanical or key fob key. It is also able to copy the data of an existing key to make duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with a computer. They also feature a bidirectional user interface to work with an immobilizer system.

Transponder Chips
If your car was built within the last 20 years, then it has a transponder inside of it. This is the little plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then absorbed by a special antenna attached to the barrel of ignition. The computer system of the vehicle is then able to verify that the key's transponder chip is the correct one for your car.
This prevents the vehicle from being started through hot-wiring, or by tampering. The chip inside the car key ensures that the owner is the person who owns the vehicle. This helps to prevent car theft.
Transponder keys that are regular in shape like regular keys, but with a plastic top. The chip is contained within the plastic part of the key and there are different types of cuts on these keys: a standard cut laser cut (also called a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil emits an electrical signal when the transponder is put into ignition barrel. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer onboard the car is able to recognize the signal as correct it will turn off the vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine and alert you with flashing lights and an alarm. This function is designed to discourage people from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and skilled criminal could still bypass this system using a special device that blocks the signal.
As you can see there are quite number of benefits to having transponder keys. Every car owner must take this into consideration if they wish to protect their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely or making chirping sounds to help find a car in a parking lot, today's key fobs can also switch on a heated steering wheel, or roll down all windows with just a single press. These extra features can make it difficult for you to find your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies which are transmitted via an antenna that is located in the middle of the key. This communication is encrypted to stop others from intercepting or replicating the signal.
There are a few different ways to program a key fob depending on the vehicle's make and model. Certain cars let you do it yourself. However, most newer models require you to visit an expert locksmith or dealer to program a new key fob or an additional one.
When you hit the button on a key fob it transmits an informational code to the car's receiver that it is linked to. The receiver compared the information with the 'allowed signals' that are stored in the key fob, and then locks or opens the car's door. If the information isn't in line, a chirping sound is heard and the car isn't allowed to operate.
Once the car is linked with a specific fob it will only accept signals from that device. Other fobs won't work with the car, despite the fact that they look like. This ensures the security of the computer system of the car and prevents unauthorized key fobs gaining control of it.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements supplied by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise which can only be obtained in the dealer's service department. Some aftermarket fobs, usually ones for older models with less advanced systems can be programmed with out the need for a dealer.
