The latest models come with computers with improved anti-theft protection. In order to work properly, these cars require that a transponder chip-integrated key be programmed into the vehicle by a professional locksmith or a car dealer/mechanic.
Professional locksmiths can carry out a variety of different types of programming for keys to cars. 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 type of key programming is called EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.
Other kinds of key programming can be carried out by anyone. These are usually done by using the onboard diagnostics port, which can be accessed with a special key-fob-programming tool. Locksmiths can execute this method with the help of a guide online and the owner's manual.

A keyprogrammer can reprogram the transponder chip of the new mechanical key or key fob. It can also clone the data of an existing key, allowing duplicates to be made. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They come with diagnostic software that 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 in the last 20 years. It's the small plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is absorbed by a special antenna that is attached to the ignition barrel. The computer system in the vehicle can then verify that the transponder chip of the key is the right one for your car.
This prevents the vehicle from being started through either hot-wiring or by manipulating. The chip in the car 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 look like normal keys but they have a plastic cap. The chip is contained within the plastic portion of the keys. There are various cuts: a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
The circuit in the induction coil will emit an electrical signal when the transponder is put into ignition barrel. The signal is taken up by the chip, which then transmits a signal to the vehicle. If the computer onboard the car detects the signal as valid it will turn off the car immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine, and will notify you via flashing lights and siren. programming car key is designed to discourage those who would attempt to alter the vehicle. However, it is not an unbreakable security measure. A skilled and determined thief might be able bypass this system by employing a device designed to detect the signal.
As you can see, there are quite a few advantages to getting transponder keys. This is something that all vehicle owners should consider if they want to protect their investment and decrease the risk of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start your car remotely, make chirping noises to aid in finding a car or turn on the heated steering wheel. 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 via an antenna in the center of the key. The communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the model and make 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 a second fob.
When you press the button on a key fob, the microchip sends an indication to the receiver inside the car with which it is linked. The receiver compares this information with the signals that are allowed in the fob and then either locks or opens the door. If the information doesn't match, the car will not be allowed to drive.
After the car has been connected to a specific fob, it only accepts signals from the device. Other fobs won't work with the car, even though they look similar. This is to safeguard the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.
Most dealerships with newer cars will only work with cars with original fobs or genuine replacements offered by the manufacturer. It is because the only place with the knowledge to create a replacement fob is in a dealer's service department. Some aftermarket fobs, usually those from older models that have less advanced systems can be programmed without the need for a dealership.
