In order to work properly, these cars require that a transponder chip key be programmed to the vehicle by a certified locksmith or a car dealer/mechanic.
Professional locksmiths are able to perform various kinds of programming for keys for cars. Certain types are more complex and require advanced tools. These tools are generally not accessible to the general public and are used only by professionals. This kind of key programming is called EEPROM Programming. It requires expertise in soldering, electronic knowledge and a significant amount of time.
Other forms of programming for car keys are much simpler and can be performed by the average person.

A keyprogrammer can reprogram the transponder chip of a new mechanical key or key fob. It can also clone information from an existing key in order to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with the computer as well as an interface that works bidirectionally with the immobilizer system.
There are a variety of keyprogrammers that are available on the market. They are available in a variety of shapes, sizes and colors. Some are inexpensive and others can cost thousands of dollar.

Transponder Chips
If your car was manufactured in the last 20 years, then it has a transponder inside of it. It's a tiny plastic piece in the head of your key that contains a 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. This signal is then taken up by the antenna that is positioned around the ignition barrel of your vehicle. This allows the vehicle's computer system to determine if the transponder chip that is in the key is the right one for your particular car.
This is what stops from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip in the car key verifies that the owner is the one who is the owner of the vehicle. automotive key programming helps to reduce the risk of theft from your car.
Regular transponder keys are designed like regular keys and have a plastic top. The chip is located inside the plastic portion of these keys. There are several different cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
The circuit in the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the onboard car computer recognizes this signal as being the right one, it will disable the vehicle's immobilizer and allow the engine to start.
If the car doesn't recognize the transponder as the correct signal, it will not start the engine and warn you with flashing lights and siren. This is designed to discourage people from attempting to tamper with the vehicle, but it's not a 100% security measure. A determined and skilled thief can still get around this system using a special device that detects 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 decrease the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also turn on the vehicle remotely, emit chirping sounds to help locate the car or turn on the heated steering wheel. These additional features can make it difficult for you to find your car keys.
Key fobs communicate with one with the car via radio frequencies that are transmitted by an antenna in the middle of the key. This communication is encrypted to stop others from stealing or stealing the signal.
You can program a keyfob in different ways based on the model and make of your vehicle. You can sometimes do this yourself, however most modern automobiles require an expert locksmith or dealer to program a replacement or a second fob.
When you hit the button on a key fob the microchip inside sends an informational code to the car's receiver that it is paired with. The receiver compares this information to the 'allowed' signals in the fob and then either opens or locks the door. If the data doesn't match an chirping sound is heard and the car isn't able to operate.
Once the car is connected to a specific fob, it only accepts signals from that device. Other fobs won't work with the car, even if they appear like. This ensures the security of the computer system of the vehicle and stops the use of unauthorized key fobs to gain control over it.
The majority of newer dealerships will only accept cars with original fobs or genuine replacements offered by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise that is only available in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by customers without the need of an authorized dealer.
