Self Programming
As technology for cars has improved over the years, the ignition keys have evolved as well. The days of the simple mechanical keys that you could purchase from the hardware shop for less than $10 are long gone. The latest models come with computers that have improved anti-theft security. The cars require a transponder chip-integrated key to be programmed by a professional locksmith, mechanic or dealer for proper operation.
Professional locksmiths can perform various types of programming for keys for cars. Certain types are extremely complex and may require sophisticated tools. These tools aren't usually available to the public and are used only by professionals. This type of car key programming is referred to as EEPROM Programming and requires soldering, electronic expertise, and a lot of time.
Other types of car key programming are a lot simpler and can be performed by the average person. These are done using the onboard diagnosis port, which can be accessed with a special tool for key-fob programming. A locksmith can perform this method with the help of a guide online and the owner's manual.

They have diagnostic software that allows them to communicate with the computer and also provide bidirectional interfaces to work with the immobilizer system.

Transponder Chips
Transponder chips are likely to be found in cars manufactured in the last 20 years. This is a little plastic thing inside the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is then absorbed by the special antenna that is fitted around the barrel that controls your ignition in your car. This allows the vehicle's computer system to determine if the transponder chip inside the key is the correct one for the car you have.
This stops the vehicle from being started through either hot-wiring or by altering the key. The chip inside the key confirms that the owner is the one who owns the vehicle. This will help reduce the possibility of theft from your vehicle.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip is contained within the plastic portion of these keys. There are several different cuts that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
A circuit inside the induction coil will emit signals when the transponder is placed in the the ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the car's computer recognizes this signal as being the correct one, it will disable the immobilizer on the vehicle and allow the engine to start.
If the vehicle doesn't recognize the transponder signal as being the correct one, it will keep the engine from starting and will notify you by flashing its lights and sounding an alarm. This feature is designed to discourage those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A skilled and determined criminal may still be able to get around this system employing a device designed to detect the signal.
It is evident that the transponder is a good option. Every car owner should consider this if they wish to protect their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate a car in a parking space Key fobs today can also activate the heated steering wheel or roll down all windows with just a single press. Many of these extra features may appear convenient but they could make it difficult for you to keep track of your car keys.
Key fobs communicate with each with the car via radio frequencies which are transmitted through an antenna in the center of the key. This communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.
Keyfobs can be programmed in different ways based on the model and make of your vehicle. It is possible to do this yourself, but the majority of newer cars require that you visit a dealer or professional locksmith to program a replacement or additional fob.
When you press the button on your key fob it transmits an encoded code to the car's radio 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's doors. If the information doesn't match the fob's information, the car won't be allowed to drive.
Once the car is associated with a particular fob, it can only receive signals from that device. Other fobs won't work with the car, despite the fact that they look identical. This ensures the security of the computer system in the car and prevents 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 because the only place that has the knowledge to create the replacement fob is the service department of a dealer. Certain aftermarket fobs, typically ones for older models that have less sophisticated systems can be programmed without the need for a dealership.
