These 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 kinds of programming for keys for cars. Some are complex and require sophisticated tools. These tools aren't generally available to the public and are utilized only by professionals. This kind of key programming is called EEPROM Programming. It requires the ability to solder, electronic skills and a lot of time.

This is why it's a good idea to always have two working keys for modern vehicles and have the replacement key programmed if required.
A keyprogrammer can reprogram a transponder chip on an entirely new mechanical key or key fob. It is also able to copy the data of an existing key to make duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that allows them to communicate with computers and also provide bidirectional interfaces to work with the immobilizer system.
There are many different types of keyprogrammers available on the market and they are available in all shapes and sizes. Some keyprogrammers are cheap, while others may cost thousands of dollars.

Transponder Chips
If your car was built in the past 20 years, it is likely that it has a transponder inside of it. It's a small plastic piece in the head of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
When activated by an electro-magnetic field, the chip emits a low-frequency signal. The signal is received by a specific antenna attached to the ignition barrel. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the correct one for your car.
This stops the vehicle from being started through either hot-wiring or by altering the key. The chip inside the key ensures that the owner is the one who owns the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular metal keys with an outer layer of plastic. The chip is located inside the plastic portion of these keys. There are a variety of cuts such as a standard cut a Laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.
A circuit inside the induction coil emits a signal when the transponder is placed in the an ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer onboard the car detects the signal as valid, it will disable vehicle immobilizer, allowing the engine to start.
If the vehicle does not recognize the transponder signal as the proper one, it will keep the engine from running and will notify you by flashing its lights and sounding siren. This feature is intended to deter people from trying to hack into the vehicle, however it's not a 100% security measure. A skilled and determined criminal could still be able to get around this system using a device that can intercept the signal.
As you can see there are quite number of advantages to having transponder keys. This is something that all car owners should think about if they want to safeguard their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find a car in a parking lot, today's key fobs can also turn on a heated steering wheel or open all windows with a single push. automotive key programming can make it difficult for you to locate your car keys.
Key fobs make use of radio frequencies to communicate with one another and the car. These frequencies are sent through a small antenna located in the middle of the key. This communication is encrypted to stop others from intercepting or replicating the signal.
There are several ways to program a key fob based on your vehicle's make and model. You may be able to do it yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on a key fob, the microchip transmits a signal to the receiver inside the vehicle with which it is paired. The receiver compared this information to the signals that are allowed in the fob and then either opens or closes the door. If the data does not match the fob's information, the car won't be allowed to run.
After the car has been connected to a specific fob, it can only receive signals from that device. Other fobs won't work with the car, even though they appear similar. This safeguards the integrity of the computer system of the vehicle and stops unauthorised key fobs from taking control over it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements sold by the manufacturer. This 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 typically for older models that have less sophisticated systems -- can be programmed by the consumer without the need of dealers.
