The cars require a transponder chip-integrated key to be programmed by a professional locksmith car dealer or mechanic to function properly.
Professional locksmiths can carry out various kinds of programming for car keys. Some are complex and require specialized tools. These tools are usually not accessible to the general public and are used only by professionals. This kind of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot time.

These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software, which allows them to communicate with computers. They also have a bidirectional interface to work with an immobilizer system.

Transponder Chips
Transponder chips are likely to be found in cars manufactured within the last 20 years. It's the tiny piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your car.
When it is activated by an electromagnetic field the chip emits a low-level signal. This signal is then amplified by the specific antenna that is positioned around the barrel that controls your ignition in your car. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the right one for your specific vehicle.
This is what prevents from modifying or hot-wiring the ignition system of the vehicle to turn it on. The chip in the car key ensures that the owner is the person who owns the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular metal keys with a plastic top. The chip itself is housed in the plastic portion of the key, and there are a few different cuts that can be found on the keys: a standard cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer in the car is able to recognize the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as being the proper one, it will stop the engine from running and will notify you by flashing its lights and sounding siren. This function is designed to discourage individuals from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and determined criminal may still be able to bypass this system by employing a device designed to intercept the signal.
As you can see, there are quite a few advantages to getting transponder keys. Every car owner must take this into consideration in order to safeguard their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making sound chirps to help locate the car in a parking lot keys of today can also activate the heated steering wheel or roll down all of the windows with a single button push. These extra features could make it difficult to find your car keys.
Key fobs communicate with one other and the car using radio frequencies which are transmitted through an antenna that is located in the middle of the key. This communication is encrypted, which helps to stop others from stealing and replicating the signal.
You can program a keyfob in different ways based on the make and model of your vehicle. It is possible to do this yourself, but the majority of newer automobiles require a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob, the microchip transmits an indication to the receiver in the car with which it is linked. The receiver then compares this information to the 'allowed' signals in the fob and then either locks or opens the door. If the information doesn't match the fob's information, the car won't be allowed to operate.
Once the car is connected to a specific fob, it only accepts signals from the device. This means that other fobs won't be able to work with the vehicle, even though they look the same. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control over it.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements supplied by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security expertise that can only be found in the dealer service department. Some aftermarket fobs, usually ones for older models with less advanced systems can be programmed without the need for a dealer.
