The newer models have computer systems that are more secure against theft. To function properly, these cars require that a transponder chip-integrated key be programmed to the vehicle by a certified locksmith or car dealer/mechanic.
Professional locksmiths can perform a variety of different types of programming for keys for cars. Certain types are extremely complex and may require advanced tools. These tools aren't generally available to the public and are only used by professionals. This kind of programming is referred to as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot time.
Other kinds of key programming can be performed by anyone. These are done using the onboard diagnosis port, which is accessible by a specific tool for key-fob programming. This method can be performed by a trained locksmith using an online guide or an owner's manual.

Key Programmers
Modern cars require a key-programming method to start the vehicle's system and to start the car. In a number of cases keys must be set up by the dealer or an auto locksmith. This is because the key might not function correctly, or it will not start the vehicle in any way. The reason is because the new key has not been programmed to the car's system. This can be very costly. It's best to have two keys that are compatible for your modern car so you can program the replacement key when needed.
Keyprogrammers can recode a transponder chip on the new mechanical key or key fob. It can also clone the data of an existing key in order to create 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 have a bidirectional user interface to work with an immobilizer system.

Transponder Chips
Transponder chips can be found in vehicles manufactured within the past 20 years. It's the tiny plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car.
When it is activated by an electro-magnetic field, the chip emits a low level signal. The signal is then absorbed by a special antenna attached to the barrel of ignition. This allows the computer in your vehicle system to verify that the transponder chip in the key is the right one for your specific vehicle.
This stops the vehicle from starting by hot-wiring, or by tampering. The chip inside the key verifies that the owner is the one who is the owner of the vehicle. This helps to prevent car theft.
Transponder keys appear like normal keys but have a plastic cap. The chip itself is housed in the plastic portion of the key, and there are different kinds of cuts available on these keys: a regular standard cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil will emit signals when the transponder is inserted into ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the onboard car computer recognizes this signal as the correct one, it will disable the vehicle immobilizer and allow the engine to begin.
If the vehicle does not recognize the transponder signal as the right one, it will keep the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage those who would attempt to alter the vehicle. However it isn't an absolute security measure. A skilled and determined thief could still bypass this system with a specially designed device that detects the signal.
It is evident that the transponder is a good option. This is something that all vehicle owners should consider if they want to safeguard their investment and reduce the risk of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start your car from a distance, make chirping sounds to aid in finding the car, or turn on the heated steering wheel. Many of these extra features might seem useful, but they can also make it harder for you to keep track of your car keys.
Key fobs communicate with each other and the car using radio frequencies that are transmitted by an antenna in the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and re-transmitting the signal.
You can program a keyfob in various ways based on the model and brand of your car. Certain models allow you to do this yourself. However, the majority of newer models require you to visit a professional locksmith or dealer to program a new key fob, or an alternative one.
When you hit the button on a key fob the microchip inside sends a code to the car's radio that it is paired with. The receiver then compares this information to the 'allowed' signals inside the fob, and either opens or locks the door. If the information does not match the signals, the car will not be allowed to operate.
When a car is connected with a specific fob it will only accept signals from the device that is associated with it. This means that other fobs won't work with the vehicle, even though they look the same. programming car key of the computer system that runs the car and prevents unauthorized key fobs gaining control over it.
Most newer car dealerships will only deal with cars that have original fobs or genuine replacements sold by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills that can only be found in the dealer service department. Certain aftermarket fobs, typically ones for older models with less sophisticated systems can be programmed with out the need for a dealership.
