The newer models have computers with improved anti-theft protection. To function properly, these cars require that a transponder chip key be programmed into the vehicle by a certified locksmith or mechanic/car dealer.
There are many types of car keys programming that can be accomplished by professional locksmiths. Some are very complex and may require sophisticated tools. These tools are generally not available to the general public and are only used by professionals. This kind of key programming is called EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.

The reason is because the new key hasn't been programmed to the automobile's system, and this could be very costly. This is why it's a great idea to have two keys that work for modern vehicles and have the replacement key programmed if needed.
A keyprogrammer is a tool which can reprogram the transponder chip into a new key fob or mechanical key. It is also able to copy information 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 enables them to communicate with the computer and also provide a bidirectional interface for working with the immobilizer system.
There are a myriad of types of keyprogrammers on the market. They are available in a variety of sizes, shapes, and colors. Some are affordable while others are advanced and can cost thousands of dollars. Certain are designed for specific vehicles and can provide advanced diagnostics of the car's electronic system.

Transponder Chips
Transponder chips are likely to be found in cars manufactured within the past 20 years. It's a small piece of plastic in the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is attached to the ignition barrel of your vehicle. This allows the vehicle's computer system to confirm that the transponder chip inside the key is the correct one for your particular car.
This prevents the vehicle from being started by hot-wiring or tampering. The chip inside the car key confirms that the owner is the person who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys that are regular in shape like regular keys, but with a plastic top. The chip is housed in the plastic portion of the key and there are a few different types of cuts on these keys: a regular standard cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.
A circuit inside the induction coil emits an electrical signal when the transponder is placed in the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer in the car is able to recognize the signal as valid it will turn off the car immobilizer to allow the engine start.
If the car does not recognize the transponder signal as being the correct one, it will stop the engine from starting and will notify you by flashing its lights and sounding an alarm. This feature is designed to discourage individuals from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined criminal may still be able to escape this security system by employing a device designed to intercept the signal.
You can see that the transponder is a good option. All car owners must take this into consideration in order to safeguard their investment and minimize theft risk.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start your vehicle from a distance, make chirping sounds to help locate a car or turn on the heated steering wheel. A lot of these features may seem convenient but they could make it more difficult to keep track of your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted through a small antenna located in the middle of the key. This signal is encrypted to prevent others from stealing or stealing the signal.
There are several ways to program a key fob based on the model and make. It is possible to 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 the button on a key fob the microchip transmits a signal to the receiver inside the car with which it is paired. The receiver then compares this information to the 'allowed' signals stored on the fob and either opens or closes the door. If the information does not match the fob's information, the car won't be allowed to run.
Once the car is linked with a particular fob, it will only receive signals from that specific device. As a result, other fobs won't be able to work with the vehicle even though they appear 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.
The majority of newer dealerships will only deal with vehicles that have original fobs or genuine replacements offered by the manufacturer. This is because preparing a replacement fob requires technological and security knowledge that is only available in the dealer's service department. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by customers without the need of dealers.
