These cars require a transponder-chip integrated key to be programmed by a professional locksmith mechanic or dealer for proper operation.
Professional locksmiths can carry out various kinds of programming for car keys. Certain types are extremely complex and require sophisticated tools. These tools are generally not accessible to the general public and are only used by professionals. This type of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.
Other kinds of key programming can be carried out by anyone. They are accomplished using the onboard diagnostic port, which can be accessed with a special tool for key fob programming.

This is because the key could not function properly or start the vehicle in any way. This is because the new key has not been programmed into the vehicle's system - and this can be quite expensive. It is best to have two keys that work for the modern automobile so that you can program the replacement key when required.
A keyprogrammer is a tool that recodes the transponder chip into a new key fob or mechanical key. It is also able to copy the information from an existing key which allows duplicate keys to be created. 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 a computer. They also feature a bidirectional user interface for working with an immobilizer system.
There are many various kinds of keyprogrammers that are available, and they come in all sizes and shapes. Some are affordable while others are sophisticated and could cost thousands of dollars.

These are less expensive than visiting a dealership however, they're not cheap. Before you purchase one, do some research on the seller. Some are not reliable and could damage your vehicle.
Transponder Chips
If your car is made within the past 20 years, it is likely that it has a transponder chip inside of it. It's a small piece of plastic in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then taken up by an antenna that is attached to the ignition barrel. The computer system of the vehicle is then able to verify that the transponder chip of the key is the right one for your car.
This prevents the vehicle from being started by hot-wiring, or by tampering. The chip inside the car key verifies that the owner is the one who is the owner of the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular metal keys with a plastic top. The chip is contained within the plastic portion of the keys. There are several different cuts that are a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe.
A circuit within the induction coil emits an electrical signal when the transponder is placed in the an ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the computer onboard the car is able to recognize the signal as valid it will turn off the car immobilizer so that the engine can start.
If the car doesn't recognize the transponder as being the proper 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 an unbreakable security measure. A determined and skilled thief could still evade this system using a special device that blocks the signal.
You can see that the transponder is an excellent option. This is something that all vehicle owners should consider if they want to safeguard their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making chirping sounds to help find the car in a parking lot Key fobs today can also turn on a heated steering wheel or open all windows with just a single click. These extra features could make it difficult to find your car keys.
Key fobs utilize radio frequencies to connect with one another and with the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. The transmission is encrypted, which helps prevent others from intercepting and retransmitting the signal.
Keyfobs can be programmed in different ways based on the make and model of your vehicle. Some cars allow you to do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a replacement key fob, or an alternative one.
When you press the button on your key fob, the microchip inside transmits a code to the car's receiver that it is linked to. The receiver then compares this information with the signals that are allowed inside the fob, and either opens or closes the door. If the information does not match the fob's information, the car won't be allowed to run.
Once the car is linked with a specific fob, it will only accept signals from that device. This means that other fobs won't work with the vehicle even though they look the same. This ensures the security of the computer system that runs the car and prevents unauthorized key fobs gaining control over it.
Most dealerships with newer cars will only accept cars that have original fobs or genuine replacements offered by the manufacturer. It is because the only place that has the experience to design the replacement fob is the service department of a dealer. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for a dealership.
