The latest models are equipped with computer systems that are more secure against theft. In order to work properly, these cars require that a transponder chip-integrated key be programmed to the vehicle by a professional locksmith or mechanic/car dealer.
Professional locksmiths are able to perform various types of programming for keys to cars. Some are extremely complicated and may require sophisticated tools. These tools are usually not accessible to the general public and are only used by professionals. This type of car key programming is known as EEPROM Programming and requires soldering, electronic skills, and a lot of time.
Other types of programming for car keys are a lot simpler and can be performed by anyone who is able to. They are accomplished using the onboard diagnosis port, which is accessible with a special tool for key fob programming.

Key Programmers
Modern automobiles require a key-programming procedure to initialize their vehicle's systems and to start the car. In some instances the key needs to be programmed by an auto locksmith or a dealer. The key may not function properly or not start the car at all. This is because the key hasn't yet been programmed into the vehicle's system. This can be costly. It is best to have two keys that work with your current car so you can program the replacement key when needed.
A keyprogrammer is a tool which can reprogram the transponder chip into the form of 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 an interface that works bidirectionally with the immobilizer system.
There are a number of various kinds of keyprogrammers that are available and they are available in all sizes and shapes. Some keyprogrammers are cheap, while others may cost thousands of dollars. Some are specifically designed for certain types of cars and can provide advanced diagnostics for your car's electronic systems.

Transponder Chips
Transponder chips can be found in cars manufactured within the past 20 years. This is the little plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to your car.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by the antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system in the vehicle can then verify that the chip in the key's transponder is the right one for your vehicle.
This prevents the vehicle from being started by hot-wiring, or by tampering. The chip inside the key verifies that the owner is the person who is the owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys appear like regular metal keys but they have a plastic cap. The chip is located inside the plastic part of the keys. There are various cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe.
Source in the induction coil emits an electrical signal when the transponder is inserted into the ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer inside the car recognizes the signal as being correct it will turn off the car immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as being the right one, it will stop the engine from starting and will notify you by flashing its lights and sounding siren. This feature is designed to discourage people from tampering with the vehicle. However it's not a foolproof measure of security. A determined and skilled thief could still evade this system with a specially designed device that detects the signal.
It is evident that a transponder is a great option. This is something that all car owners should consider if they want to protect their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making chirping sounds to help find a car in a parking space, today's key fobs can also turn on a heated steering wheel or roll down all windows with just a single click. A lot of these additional features might seem useful but they could make it difficult for you to keep track of your car keys.
Key fobs use radio frequencies to communicate with one another and with the car. The frequencies are transmitted through a small antenna located inside the middle of the key. The signal is encrypted to prevent others from stealing or stealing the signal.
Keyfobs can be programmed in different ways based on the model and brand of your car. You can sometimes do this yourself, however most modern automobiles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press a key fob's button, the microchip inside transmits an informational code to the car's receiver it is linked to. The receiver compared this information with the 'allowed' signals stored inside the fob, and either opens or locks the door. If the data does not match the signals, the car will not be allowed to operate.
Once the car is linked with a particular fob, it will only receive signals from the device that is associated with it. In turn, other fobs will not work with the vehicle even if they look the same. This helps to protect the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.
The majority of newer dealerships will only accept cars with original fobs, or genuine replacements sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge that is only available in the dealer's service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems can be programmed by customers without the need for an authorized dealer.
