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 can carry out various kinds of programming for car keys. Certain types are more complex and require specialized tools. These tools are usually not accessible to the general public and are used only by professionals. This kind of programming is referred to 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 can be done by using the onboard diagnosis port, which is accessible via a tool specifically designed for key-fob programming.

car key programming
If your car was built in the last 20 years, then it has a transponder inside of it. This is a little plastic thing on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. This signal is then amplified by the specific antenna that is fitted around the ignition barrel of your car. The computer system of the vehicle can then verify that the transponder chip of the key is the correct one for your car.
This prevents the vehicle from starting by either hot-wiring or by altering the key. The chip inside the key verifies that the owner is the one who owns the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys look like normal keys, but with a plastic cap. The chip is inside the plastic portion of these keys. There are several different cuts that are a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.
The circuit in the induction coil emits signals when the transponder is inserted into ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the onboard car computer recognizes this signal as the correct one, it will turn off the immobilizer on the vehicle and allow the engine to start.
If the vehicle doesn't recognize the transponder as being the proper signal, it won't start the engine and alert you with flashing lights and an alarm. This is designed to deter people from trying to tamper with the vehicle, but it's not a 100% security measure. A skilled and determined thief might be able escape this security system by using a special device to detect the signal.
As you can see there are quite a number of benefits to having transponder keys. All car owners should consider this in order to safeguard their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making chirping sounds to help find a car in a parking lot keys of today can also activate a heated steering wheel or roll down all windows with just a single click. These additional features can make it difficult to locate your car keys.
Key fobs make use of radio frequencies to communicate with each other and with the car. These frequencies are transmitted by a small antenna within the middle of the key. This communication is encrypted, which helps to keep others from stealing and retransmitting the signal.
Keyfobs can be programmed in various ways based on the model and make of your vehicle. You can sometimes do this yourself, but the majority of newer automobiles require an expert locksmith or dealer to program a replacement or a second fob.
When you hit the button on a key fob it transmits a code to the car's receiver that it is paired with. The receiver then compares this information with the 'allowed' signals on the fob and either opens or closes the door. If the information does not match, the car will not be allowed to drive.
After the car has been connected to a specific fob, it only accepts signals from that device. Other fobs will not work with the car, despite the fact that they look similar. This ensures the security of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control of it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise that can only be found in the dealer's service department. Some fobs from the aftermarket, especially those from older models that have less sophisticated systems can be programmed with out the need for a dealership.
