In order to work correctly, these vehicles require that a transponder chip key be programmed to the vehicle by a certified locksmith or car dealer/mechanic.
There are several types of car key programming that can be accomplished by professional locksmiths. Some are complex and require specialized tools. These tools are generally not accessible to the general public and are used only by professionals. This kind of programming is referred to as EEPROM Programming. It requires the ability to solder, electronic skills and a lot of time.

They come with diagnostic software that enables them to communicate with the computer, and they also have a bidirectional interface for working with the immobilizer system.

Transponder Chips
Transponder chips can be found in vehicles manufactured in the last 20 years. It's a tiny plastic piece in the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then received by a specific antenna attached to the barrel of ignition. This allows the car's computer system to verify that the transponder chip in the key is the correct one for your particular car.
This is what stops from modifying or hot-wiring the ignition system of your vehicle to get it started. The chip inside the key also verifies that you are the legal owner of the vehicle. programming car key helps to reduce the risk of theft from your car.
Transponder keys that are regular in shape like regular keys and have a plastic top. The chip is contained within the plastic part of the key, and there are a few different types of cuts on the keys: a standard cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.
A circuit within the induction coil will emit an electrical signal when the transponder is inserted into ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer inside the car detects the signal as correct it will turn off the vehicle immobilizer to allow the engine start.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine and will warn you with flashing lights and an alarm. This system is designed to deter those who would attempt to alter the vehicle. However it's not a foolproof measure of security. A skilled and determined thief could still bypass this system with a specially designed device that intercepts the signal.
As you can see there are quite number of benefits to having transponder keys. This is something that all car owners should consider if want to protect their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making sound chirps to help locate the car in a parking space, today's key fobs can also activate a heated steering wheel or open all windows with a single button push. Many of these extra features may seem convenient but they could make it difficult for you to keep the keys to your car.
Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are transmitted via a small antenna that is located in the middle of the key. This communication is encrypted to stop others from stealing or stealing the signal.
Keyfobs can be programmed in various ways based on the make and model of your vehicle. You may be able to do it yourself, but most newer cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on a key fob, the microchip transmits signals to the receiver inside the car that it is paired. The receiver compares the information with the 'allowed signals' stored on the key fob and then it opens or closes the car's doors. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate.
Once the car is linked with a particular fob, it will only accept signals from that device. Other fobs won't work with the car, even if they appear identical. This safeguards the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control of it.
The majority of newer dealerships will only accept cars 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 skills which can only be obtained in the dealer's service department. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
