Newer models are equipped with computers that have improved security against theft. To function properly, these cars require that a transponder chip-integrated key be programmed into the vehicle by a professional locksmith or mechanic/car dealer.
Professional locksmiths can perform various types of programming for keys to cars. Certain types are extremely complex and require sophisticated tools. These tools aren't generally available to the public and are utilized only by professionals. This kind of car key programming is known as EEPROM Programming and requires soldering, electronic knowledge and a lot of time.
Other kinds of car key programming are much easier and can be done by anyone who is able to.

This is because the key hasn't yet been programmed into the car's system. This can be expensive. This is why it's a great idea to always have two keys that work for a modern automobile, so you can get the replacement key programmed when required.
A keyprogrammer is a device that can recode the transponder chip in the form of a new mechanical or key fob key. It is also able to copy the data of an existing key in order to create duplicates. These are handheld devices that connect to the 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 interface for working with an immobilizer system.
There are a myriad of types of keyprogrammers that are available on the market. They come in all sizes, shapes, and colors.

Transponder Chips

Transponder chips are likely be found in cars that were manufactured in the last 20 years. It's the small plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When it is activated by an electromagnetic field, the chip emits a low-frequency signal. The signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system in the vehicle will then confirm that the transponder chip of the key is the correct one for your car.
This stops the vehicle from being started by either hot-wiring or by altering the key. The chip in the key also verifies that you are the legal owner of the vehicle. This can reduce car theft.
Transponder keys that are regular in shape like regular keys and have an outer layer of plastic. The chip is contained within the plastic part 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 a Ford Tibbe key.
A circuit inside the induction coil will emit signals when the transponder is put into ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the onboard car computer detects this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as the proper one, it will stop the engine from starting and will notify you by flashing its lights and sounding an alarm. This feature is intended to discourage people from attempting to alter the vehicle, but it is not a foolproof security measure. A determined and skilled thief can still get around this system using a special device that blocks the signal.
As you can see there are quite a few advantages to getting transponder keys. This is something that all car owners should consider if they want to protect their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find the car in a parking lot, today's key fobs can also turn on a heated steering wheel or roll down all of the windows with a single click. These additional features can make it difficult for you to find your car keys.
Key fobs use radio frequencies to communicate with each other and with the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. This communication is encrypted, which helps to keep others from stealing and retransmitting the signal.
You can program a keyfob in different ways based on the model and make of your car. You may be able to do it yourself, however most modern cars require that you visit an expert locksmith or dealer to program a replacement or additional fob.
When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's receiver that it is linked to. The receiver compares the information with the permitted signals stored in the key fob and then locks or opens the car door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.
Once the car is linked with a specific fob, it will only accept signals from the device that is associated with it. Other fobs will not work with the car, even though they look like. This safeguards the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control of it.
The majority of newer dealerships will only deal with vehicles that have original fobs, or genuine replacements sold by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security skills that is only available in the dealer service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by consumers without the need for an authorized dealer.
