The latest models come with computer systems that are more secure against theft. The cars require a transponder chip-integrated key to be programmed by a professional locksmith, mechanic or dealer in order to function properly.
Professional locksmiths are able to perform various kinds of programming for keys for cars. Certain types are extremely complex and require sophisticated tools. These tools are usually not available to the general public and are used only by professionals. This type of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.
Other kinds of key programming can be done by anyone. They are accomplished using the onboard diagnosis port, which is accessible by a specific tool for key-fob programming. This method can be done by a trained locksmith using an online guide or the vehicle's owner's manual.

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 set up by the dealer or auto locksmith. The key may not work properly or it may not even start the car at all. This is because the new key hasn't been programmed to the car's system - and this can be quite costly. It is recommended to have two keys that work with your current car so you can program the replacement key when needed.
A keyprogrammer is a tool that can recode the transponder chip into an entirely new key fob or mechanical key. It can also clone information from an existing key in order to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional user interface that works with an immobilizer system.

Transponder Chips
Transponder chips can be found in vehicles manufactured in the last 20 years. It's a small plastic piece inside the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is fitted around the ignition barrel of your vehicle. The computer system of the vehicle is then able to verify that the transponder chip of the key is the correct one for your vehicle.
This is what prevents from modifying or hot-wiring the ignition system of the vehicle to start it. The chip inside the key also confirms that you are the legal owner of the vehicle. This helps to reduce the risk of theft from your car.

A circuit inside the induction coil will emit signals when the transponder is placed in the ignition barrel. The signal will be taken up by the chip and cause it to send a signal back to the car. If the computer inside the car recognizes the signal as correct it will turn off the vehicle immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to deter people from trying to alter the vehicle, but it isn't a foolproof security measure. A determined and skilled thief could still bypass this system by using a specific device that intercepts the signal.
As you can see, there are quite a number of benefits to having a transponder key. This is something that all car owners should think about if they want to safeguard their investment and decrease the risk of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start the car from a distance, make chirping sounds to aid in finding cars, or switch on the heated steering wheel. Many of these extra features might seem useful but they could make it more difficult to keep the keys to your car.
Key fobs communicate with each other and with the car through radio frequencies that are transmitted via an antenna in the center of the key. The transmission is encrypted, which helps to stop others from stealing and re-transmitting the signal.
You can program a keyfob in different ways based on the make and model of your vehicle. You can sometimes do this yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or a second fob.
When you press a key fob's button it transmits a code to the car's radio that it is linked to. reprogram car key compared this information with the 'allowed' signals inside the fob, and either opens or closes the door. If the information does not match the signals, the car will not be allowed to operate.
Once the car is paired with a specific fob, it will only accept signals from the device. Other fobs won't work with the car, even if they look similar. This helps to protect the integrity of the car's computer system and to prevent unauthorized key fobs from gaining control of the vehicle.
Most newer car dealers will only work on a car with 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 is only available in the dealer's service department. Some aftermarket fobs, usually those from older models with less advanced systems can be programmed with out the need for a dealer.
