To function properly, these cars require that a transponder chip-integrated key be programmed to the vehicle by a professional locksmith or a car dealer/mechanic.

These tools aren't usually available to the public and are utilized only by professionals. This type of car key programming is referred to as EEPROM Programming and requires soldering, electronic knowledge and a lot of time.

Key Programmers

In some instances, the key will need to be programmed by an auto locksmith or dealer. This is because the key may not function correctly, or it will not start the vehicle at all. This is because the new key has not been programmed to the automobile's system, and this could be quite expensive. This is why it's a good idea to always have two keys working for a modern car, so you can get the replacement key programmed when necessary.
A keyprogrammer can recode the transponder chip of a new mechanical key or key fob. It can also clone the information from an existing key which allows duplicate keys to be made. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software that enables them to communicate with computers and also provide a bidirectional interface for working with the immobilizer system.
There are a number of different kinds of keyprogrammers on the market and they are available in all shapes and sizes. Certain keyprogrammers are affordable and others could cost thousands of dollars. Certain models are specifically designed for vehicles and can provide advanced diagnostics of the vehicle's electronic system.

Transponder chips are likely to be found in vehicles manufactured in the last 20 years. It's the small plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to confirm that the transponder chip that is in the key is the correct one for your specific vehicle.
This is what prevents from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip inside the car key confirms that the owner is the person who is the owner of the vehicle. This helps to prevent car theft.
Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is housed within the plastic part of the key and there are different types of cuts on these keys: a cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.
A circuit inside the induction coil emits an electrical signal when the transponder is placed in the an ignition barrel. The signal will be absorbed by the chip and cause it to transmit a signal to the car. If the computer on the car recognizes this signal as the correct one, it will disable the immobilizer on the vehicle and allow the engine to start.
If the car does not recognize the transponder signal as the proper one, it will prevent the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage those who would attempt to alter the vehicle. However it's not an absolute security measure. A skilled and committed thief could still be able to bypass this system by using a device that can intercept the signal.
As you can see there are quite a number of benefits to having transponder keys. All car owners should consider this when they want to safeguard their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely or making chirping sounds to help find the car in a parking lot, today's key fobs can also activate the heated steering wheel or roll down all of the windows with a single button click. A lot of these additional features may seem convenient, but they can also make it more difficult to keep the track of your car keys.
Key fobs use radio frequencies to connect with one another and the car. These frequencies are transmitted through a small antenna located within the middle of the key. The communication is encrypted, which helps stop others from stealing and re-transmitting the signal.
There are many ways to program a key fob based on the vehicle's make and model. Certain cars let you do it yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order to program a new key fob or additional one.
When you press the button on a key fob the microchip transmits signals to the receiver inside the vehicle that it is paired. The receiver compares this information to the 'allowed' signals 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 operate.
Once the car is linked with a particular fob, it will only receive signals from that specific device. Other fobs will not work with the car, despite the fact that they look similar. This helps to protect the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.
Most newer car dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security knowledge which can only be obtained in the dealer's service department. Certain aftermarket fobs, typically ones for older models with less sophisticated systems, can be programmed without the need for a dealer.
