In order to work correctly, these vehicles require that a transponder chip key be programmed into the vehicle by a certified locksmith or a car dealer/mechanic.
Professional locksmiths are able to perform various types of programming for keys to cars. Some are complex and require sophisticated tools. These tools are generally not accessible to the general public and are used only by professionals. This type of car key programming is referred to as EEPROM Programming and requires soldering, electronic skills and a significant amount of time.
Other kinds of programming for car keys are much simpler and can be accomplished by the average person.

Key Programmers
Modern vehicles frequently require a key programming process to initialize the vehicle's system and allow the car to start.

This is because the key has not yet been programmed into the vehicle's system. This could be costly. This is why it's a great idea to have two keys working for modern vehicles and have the replacement key programmed when required.
A keyprogrammer can reprogram the transponder chip on an entirely new mechanical key or key fob. It is also able to copy the data of an existing key in order to create duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with the computer and also provide a bidirectional interface for working with the immobilizer system.
There are a variety of keyprogrammers on the market. They come in all sizes, shapes and colors. Some are inexpensive while others may cost thousands of dollars. Certain models are specifically designed for certain kinds of vehicles, and they can even offer advanced diagnostics for the car's electronic systems.

Certain manufacturers employ proprietary technology that guarantees that the dealership is the only entity that can create new keys. However, other manufacturers make it simple for anyone to do it on their own.

They're less expensive than going to the dealership however, they're not cheap. Before buying one, do some research on the seller. Some aren't reliable and may damage your vehicle.
Transponder Chips
Transponder chips are likely to be found in cars manufactured within the last 20 years. This is the little plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by an antenna that is attached to the barrel of ignition. The computer system in the vehicle is then able to verify that the key's transponder chip is the right one for your car.
This is what stops from modifying or hot-wiring the ignition system of the vehicle to start it. The chip in the car key verifies that the owner is the one who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are designed like regular metal keys with a plastic top. The chip is contained within the plastic part of the key, and there are different types of cuts on these keys: a regular cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
A circuit inside the induction coil will emit a signal when the transponder is inserted into ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the computer in the car detects the signal as being correct it will turn off the vehicle immobilizer so that the engine can start.
If the car does not recognize the transponder signal as being the right one, it will prevent the engine from running and will notify you by flashing its lights and sounding a siren. This function is designed to discourage people from tampering with the vehicle. However, it is not an unbreakable security measure. A determined and skilled thief could still bypass this system by using a specific device that blocks the signal.
As key programer can see there are quite a few advantages to getting a transponder key. Every car owner should take this into consideration when they want to safeguard their investment and reduce the risk of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start your car remotely, make chirping noises to help locate cars, or switch on the heated steering wheel. These extra features can make it difficult for you to locate your car keys.
Key fobs use radio frequencies to communicate 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 communication is encrypted, which helps to stop others from stealing and replicating the signal.
You can program a keyfob in a variety of ways depending on the model and brand of your car. Certain models allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer to program a replacement key fob or additional one.
When you press the button on a key fob the microchip sends an indication to the receiver in the vehicle with which it is linked. The receiver compares this information with the 'allowed' signals in the fob and then either opens or locks the door. If the information does not match, the car will not be allowed to drive.
When a car is connected with a particular fob, it will only receive signals from that device. This means that other fobs won't be able to work with the vehicle, even though they look the same. This ensures the security of the computer system of the car and blocks the use of unauthorized key fobs to gain control over it.
Most newer car dealerships will only work with vehicles that have 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 that is only available in the dealer service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
