Key Programmers
Modern vehicles typically require a key programming process to set up the car's system and allow the car to begin. In some instances the key needs to be programmed by the dealer or auto locksmith. This is because the key may not function correctly, or it will not start the car at all. The reason is because the new key has not been programmed to the car's system - and this can be quite costly. This is why it's a good idea to always have two working keys for a modern automobile and have the replacement key programmed if necessary.
Keyprogrammers are devices that recodes the transponder chip on an entirely new key fob or mechanical key. It also can clone information from an existing key in order to create duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with a computer. They also feature a bidirectional user interface that works with an immobilizer system.
There are a number of different kinds of keyprogrammers that are available and they are available in a variety of sizes and shapes. Some are inexpensive and others could cost thousands of dollars. Some are made for specific automobiles and offer advanced diagnostics of the car's electronic system.

These are less expensive than going to a dealer, but they're still not cheap. Be sure to research the seller before purchasing one. Some aren't reliable and can damage your vehicle.
Transponder Chips
If your car was built within the past 20 years, chances are it has a transponder chip 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 code unique to your vehicle.
When it is activated by an electromagnetic field the chip emits a low level signal. This signal is then amplified by the specific antenna that is positioned around the ignition barrel of your car. The computer system of the vehicle can then verify that the chip in the key's transponder is the correct one for your car.
This stops the vehicle from being started by hot-wiring, or by manipulating. The chip inside the key also confirms that you are the legal owner of the vehicle. This can help to reduce car theft.
Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip itself is housed inside the plastic portion of the key and there are different kinds of cuts available on the keys: a standard cut laser cut (also called a sidewinder key) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal will then get received by the chip and cause it to transmit a signal back to the car. If the computer inside the car is able to recognize the signal as valid, it will disable vehicle immobilizer so that the engine can start.
If the car does not recognize the transponder signal as the proper one, it will stop the engine from starting and will alert you by flashing its lights and sounding an alarm. This function is designed to discourage people from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined thief may still be able to bypass this system by using a device that can take over the signal.
It is evident that the transponder is an excellent option. All car owners should consider this when they want to safeguard their investment and decrease the risk of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start your vehicle remotely, make chirping noises to aid in finding the car, or turn on the heated steering wheel. Many of these extra features may seem convenient, but they can also make it harder for you to keep the keys to your car.
Key fobs communicate with each other and the car using radio frequencies that are transmitted via a small antenna located in the middle of the key. This signal is encrypted to stop others from intercepting or replicating the signal.
There are several ways to program a key fob, based on the vehicle's model and make. You may be able to do it yourself, however most modern vehicles require an expert locksmith or dealer to program a replacement or a second fob.
When you press the button on a key fob the microchip transmits an indication to the receiver inside the vehicle that it is paired. The receiver compares the information with the 'allowed signals' that are stored on the key fob and then it opens or closes the car's door. If the information doesn't match the fob's information, the car won't be allowed to operate.
Once the car has been connected to a specific fob, it can only receive signals from the device. In turn, other fobs won't be able to work with the vehicle even if they appear similar. This ensures the security of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control over it.
The majority of newer dealerships will only deal with cars with original fobs or genuine replacements supplied by the manufacturer. This is because the only place with the knowledge to create the replacement fob is a dealer's service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by the consumer without the need for dealers.
