In order to work correctly, these vehicles require that a transponder chip-integrated key be programmed into the vehicle by a certified locksmith or mechanic/car dealer.
There are many kinds of car key programming that can be accomplished by professional locksmiths. Certain types are more complex and require sophisticated tools. These tools aren't generally available to the public and are utilized only by professionals. This type of car key programming is referred to as EEPROM Programming and requires soldering, electronic expertise and a lot of time.
key programmers of key programming can be done by anyone. They are accomplished using the onboard diagnosis port, which can be accessed by a specific tool for key fob programming. This method can be done by a professional locksmith using an online guide or an owner's manual.

Key Programmers
Modern cars require a key-programming method to set up their systems and then start the vehicle. In certain instances, the key will need to be programmed by an auto locksmith or dealer. This is because the key may not function correctly or start the car in any way. This is because the new key hasn't been programmed into the vehicle's system. This can be very costly. This is why it's a great idea to always have two working keys for a modern car and to have the replacement key programmed when required.
A keyprogrammer is a tool which can reprogram the transponder chip in an entirely new mechanical or key fob key. It also can clone data from an existing key in order to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with computers. They also have a bidirectional user interface for working with an immobilizer system.
There are a number of different kinds of keyprogrammers that are available and they come in a variety of shapes and sizes.

Transponder Chips
Transponder chips can be found in vehicles manufactured within the last 20 years. It's a small plastic piece in the head 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 an low-level radio signal once it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is positioned around the ignition barrel of your vehicle. The computer system in the vehicle is then able to verify that the transponder chip of the key is the right one for your vehicle.
This is the reason why doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip in the key also proves that you are the legal owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Transponder keys resemble regular metal 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 kinds of cuts available on these keys: a cut, a 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 an electrical signal. The signal will then get absorbed by the chip, causing it to send a signal back to the car. If the computer onboard the car recognizes the signal as valid it will turn off the vehicle immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder signal as the right one, it will keep the engine from running and will alert you by flashing its lights and sounding an alarm. This system is designed to deter those who would attempt to alter the vehicle. However, it is not an unbreakable security measure. A skilled and committed thief could still be able to get around this system using a special device to detect the signal.
As you can see there are quite number of benefits to having a transponder key. Every car owner should consider this if they wish to protect their investment and reduce the chance of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also turn on the vehicle from a distance, make chirping sounds to aid in finding a car, or switch on the heated steering wheel. These extra features could make it difficult to locate your car keys.
Key fobs use radio frequencies to connect with one another and with the car. These frequencies are sent through a small antenna located inside the middle of the key. This signal is encrypted to stop others from intercepting or replicating the signal.
There are many ways to program a key fob depending on the vehicle's model and make. You may be able to do it yourself, but most newer automobiles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on a key fob, the microchip sends a signal to the receiver inside the vehicle with which it is linked. The receiver compared the information with the 'allowed signals' that are stored in the key fob and then opens or locks the car's doors. If the data does not match the signals, the car will not be allowed to run.
Once the car is paired with a specific fob, it only accepts signals from that device. In turn, other fobs won't work with the vehicle even though they appear similar. This protects the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
Most dealerships with newer cars will only accept cars with original fobs, or genuine replacements supplied by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security knowledge that can only be found in the dealer's service department. Certain aftermarket fobs, typically ones for older models that have less sophisticated systems can be programmed without the need for a dealer.
